Hi, i just bought a Shappire pulse rx 570 4gb and realized that maybe my psu could not handle it because of amperage problems.

My psu is the Thelmaltake TR2 600W Non PFC.
I currently have an i5 3330 3.0Ghz, Gainward GTX 660 OC 2gb vram, 8gb RAM, 1tb HDD.

The box of the psu says: (+3,3V 22A ; +5V 18A ; +12V1 23A ; +12V2 20A; -12V 0.3A ; +5VSB 2.5V).

I do not undestand how to calculate the amperage of the psu that is going to be for the new GPU. I also failed to find the amperage for this particular gpu that i bought ¿is my PSU going to suply enough amperage?

Thanks.
 
Solution
What is the EXACT and SPECIFIC model of that TR2 unit? The reason I ask is because there are two different versions of it. Neither of them are very good, but one is EXTREMELY poor quality while the other is just slightly below mediocre.

If you have the lesser and older of the two models, I would suggest that you never use it again and immediately throw it in the trash before it damages anything, if it hasn't already.

If you have the other of the two models, I'd suggest that you begin to make plans to replace it as soon as possible if you are going to use it with anything other than a very basic system that does not use a gaming card.

As you can see at the following link, that exact model of power supply is what brought me to Tom's...

I'll gladly sell him another one if he wants to buy it as a backup. LOL.

If you sell a TR2, I think the police show up and take you straight to jail. No trial.
 
Ahh, but that's what disclaimers are for!

However, in the case of the TR2, that's ONLY if you sell one to somebody NEW. Since this is used, there are no merchantability laws governing it's sale. LOL.

For those who can't quite grasp the sarcasm, yes, it's a joke. I keep that unit around only so I can show potential customers that have one that it is not my first rodeo when it comes to the TR-600. And so that I don't ever consider taking chances with Thermaltake units, not even their Toughpower grand units which I know are good but are unrealistically overpriced.

As to the amperage of your power supply and your graphics cards requirements, your slot is only capable of 75w. The 8 pin is capable of 150w. That is a maximum of 225w your card could EVER pull. 225w divided by 12 volts is 18.75 amps. For the sake of the rest of the system we can safely say about another 150w considering you have a relatively low TDP processor at 77w. If we say 200w, to play it safe, that takes us to 425w which means having a power supply that is capable of supplying 35 amps total. So any GOOD 450-550w power supply is more than capable of handling your graphics card and the rest of the system.

The link I provided earlier at RealHardTechX offers 100% valid recommendations based on HUNDREDS of hours of testing. I don't know why you think you need to re-think a process that has already been highly polished and has no reason to be doubted. If you get a good unit that is 450w or higher, and I'd recommend a 550w unit of good quality just to give yourself some headroom for future upgrades or hardware changes, then you have no reason to need to know anything further about the requirements. The Sapphire website says 500w unit for that graphics card. If you want the official recommended amperage capabilities that Sapphire says you should have for that graphics card AND the rest of the system, then the number is going to look more like 41amps but there's no way your system and that card are going to pull 41amps continuously, ever. It would be incredibly doubtful that it could ever manage to even spike to anything near that amount. There is no need to reinvent the wheel. Just leave that to the wheel manufacturers.

The problem with your answer is that, as i stated before, there is a page that lists amperage and wattage for video cards and the rx 570 need 25A, not even close to 10A. So, until someone shows why that site is wrong, i still hold doubts (i want to be 100% sure that my pc is not going to explode). Still, thanks for your answer.
Let's say it needs those extra 15A. Now you'd need about 36A. If you get a quality psu then the rated wattage must be slightly more than the wattage from the 12v rail. If so, for >500w rated wattage then it should have no less than 40A, for 550w about 45A. That should still be enough.
What PSU do you want to get?
 
Not necessarily. The one I dealt with in my first post here, was purchased in 2013, only six years ago.
Good god, they were selling this still in 2013?
I bought mine in 2017.

Must have been old stock or something. Thermaltake hasn't made a PSU without PFC in over a decade. Selling a PSU without PFC has been illegal in the EU for over a decade, which is why all of these "230V only" PSU have cropped up.

I am thinking in buying this PSU: Xfx P1-500B-XTFR 500w, it says that have 38A in a single +12V rail.

I've checked a psu tier and XFX XT series (this includes that unit) is low ranked. Anyway, a CX550 for example has 45.8A on the 12v rail, which should give extra headroom for upgrades. It does lack OCP, but if you can push the budget to $90 for psu, the Focus+ 550w gives you OCP and 10 years warranty.

i disagree a little bit, if you search "Power requirements for graphics cards 2.0" and enter the msi page your will finde that the rx 570 need 25A. I do not know if this translates to the shappire version but i do not think both will be SO different.
That's GOT to be a mistake. There's no way that even an overclocked 570 is going to ever need 300W.

The "standard" RX 570 is generally rated at 150W TDP.

He doesn't have a "standard" card. He has a a model that specifically states up to 180w and has an 8 pin power connector. 75w slot power plus 150w for an 8 pin connector MEANS that that card COULD pull up to 225w based strictly off the standards for those connections. I'm not saying it WILL, but it CAN. You always want a power supply that is more than capable of supporting anything that your hardware CAN pull, regardless of whether or not it ever DOES pull it.

The problem is the availability of those PSU in my country (Argentina). Some of those are not reachable and some, like the Focus+, cost the triple of the Xfx. When you said low tier, that is comparable to the Termaltake or is much better?
There is not a lot of options in here. Is that Xfx or the Sentey SNP550-HS 550w which is a little bit cheaper.

The problem is that if the XFX is as low ranked as it is, then it's probably worth paying triple the cost in order to protect the rest of your system.

Are you stuck with local brick and mortar stores or are there online vendors you can link us to, so we can get a more complete look at what's available to you?

I am going to buy from Mercado libre which is an online store of the country, of course with the currency of the country. To put in perspective: the Fucus+ cost aprox. $12000 and the Xfx cost $4000. The video card (used) cost me $7000 and i have a low amount of money for the PSU now, aprox. $4000.

This might help you to find a suitable unit on your own, based on what actually IS available to you in your region. Especially if you have to source from local shops as many members from your region and south american countries in general, that I've helped in the past, have had to do.

It's not ALL inclusive, but it covers a pretty damn big chunk of what's available out there both in terms of what's good and what you should absolutely avoid.

Let's start with the biggest misconception out there, which is that if a unit has high watts it will be ok or is good. Well, that couldn't be further from the truth.

There are plenty of 750-1000w units out there that I wouldn't trust to power a string of LED lights and might in fact be a much worse choice than a unit with a significantly lower listed capacity.

If the platform isn't good to begin with, how many watts or amps it says it can support is irrelevant.

Higher 80plus certification doesn't mean anything, UNLESS it is a PSU platform that we already know is good anyhow. For example, a Seasonic Prime platinum unit is going to be a better product than a Seasonic Prime Gold unit, because we already know the Prime platform is very good, and platinum efficiency along with it shows there are some improvements internally to account for the higher efficiency.

In a case like that, it might be worth it. It's likely the unit will create less heat, it will probably have better performance in regard to ripple, noise and voltage regulation. It might shave a few pennies, or dollars, off the electric bill over the course of a year.

Other than that, it is not going to perform any better than the same platform with Gold efficiency. On the other hand, just because a unit has Titanium 80plus ratings doesn't mean the unit is any good at all. For example, there are Raidmax units with Titanium efficiency and I wouldn't trust one of those to power a light bulb. There are a lot of units like this out there.

If the platform isn't good to begin with, whether or not it has an 80plus certification or is irrelevant.

Whatever you do, don't EVER buy a power supply based on whether it has RGB or lighting, or looks like it might be a quality unit. Some of the biggest hunks of junk out there look just as good as a Seasonic Prime Ultra Titanium, but I assure you, they are not. So far there are very few very good units out there that have RGB built in. Maybe one or two models, but rest assured you'll be be paying for the lighting, not for the quality of the power supply.

I don't know what country you reside in, and I know that sometimes it's hard to come by good units in some regions, but when possible, when it comes time to get that PSU, I'd stick to the following if you can.

Seasonic. Seasonic isn't just a brand, they are a PSU manufacturer, unlike many of the PSU brands you see they make their own power supply platforms AND a great many of the very good PSU models out there from other brands like Antec, Corsair and older XFX are made by Seasonic.

Just about anything made by Seasonic is good quality for the most part. There are really no bad Seasonic units and only a very few that are even somewhat mediocre. They do make a few less-good quality OEM style units, but mostly those are not going to be units you come across at most vendors, and they are still not bad. Also, the S12II and M12II 520 and 620w units are older, group regulated models. At one time they were among the best units you could buy. Now, they are outdated and not as good as almost any other Seasonic models. They are however still better than a LOT of newer designs by other manufacturers.

The Seasonic 520w and 620w S12II/M12II units CAN be used on newer Intel platforms, if you turn off C6/C7 in the bios, but I'd really recommend a newer platform whenever possible. Prices are usually pretty good on those though, so sometimes it's worth accepting the lack of DC-DC on the internal platform. Higher capacity versions of the High current gamer are not based on that platform, so they are fine. Those being the 750w and higher versions.

Most common currently, in order of preference, would be the Seasonic Focus series, then Focus plus, then Prime, then Prime ultra. It's worth mentioning that there are generally Gold, Platinum and Titanium versions within each, or most, of those series, but that does not necessarily mean that a Focus plus Platinum is necessarily better than a Prime Gold. It only means that it scored better in the 80plus efficiency testing, not that the platform is better.

Again, don't let yourself get tangled up in the idea that a higher 80plus rating specifically means that it is a better unit than another one with a lower rating, unless you know that it is a good platform from the start. All these Focus and Prime units are pretty good so you can somewhat focus on the 80plus rating when deciding which of them to choose.

Super Flower. Super Flower is another PSU manufacturer. They are like Seasonic and they make power supplies for a variety of other companies, like EVGA. Super Flower units are usually pretty good. I'd stick to the Leadex, Leadex II and Golden Green models.They also make most of the good units sold by EVGA like the G2, G3, P2 and T2 models.

Super Flower doesn't have a very broad availability for the units with their own brand name on them, and are not available in a lot of countries but for those where there is availability you want to look at the Leadex and Leadex II models. The Golden green platform is fairly decent too but is getting rather long in the tooth as a platform AND I've seen some reviews indicating a few shortcomings on units based on this platform.

Even so, it's a great deal better than a lot of other platforms out there so you could certainly do worse than a Golden green model. Units based on the Leadex and Leadex II platforms are much better though.

Corsair. The CX and CXm units are ok as a budget option, but I do not recommend pairing them with gaming cards. The newer 2017 models of CX and CXm are better than the older ones, but still not what we'd call terrific, so if it specifically says 2017 model, or it has a capacity other than an even 100, like 550w, 650w, 750w, etc., then it's likely at least better than those older ones. Aside from that, any of the TX, RMx, RMi, HX, HXi, AX or AXi units are good. Those are listed from best to worst, with the best being the AX and AXi units.

Antec. The True power classic units are made by Seasonic, and are very good, but are not modular. The High current gamer 520w and 620w, or any other PSU you see on the market that is 520w or 620w, are also made by Seasonic, based on the S12II and M12II platform for modern versions, and are pretty good units but again they are an older platform that is group regulated so if you go with a Haswell or newer Intel configuration you will want to avoid those because they do not support the C6/C7 Intel low power states.

The Antec High current gamer 750w and 850w units are very good and are not the older design, which came in 520w and 620w capacities and were good for back then but again, are an aging Seasonic platform that is not the best choice most of the time these days. Occasionally, these older units MIGHT be the best unit available and you could do worse than one of them, but a newer DC-DC platform is desirable when possible if it doesn't mean sacrificing quality elsewhere in the platform. There are however older and newer HCG models, so exact model number will likely be a factor if choosing one of these however both the older models and the newer models are good.

Antec Edge units are ok too, but reviews indicate that they have noisy fan profiles. I'd only choose this model if it is on sale or the aesthetics match up with your color scheme or design. Still a good power supply but maybe a little aggressive on the fan profile. This may have been cured on newer Edge models so reading professional tear down reviews is still the best idea.

Antec Earthwatts Gold units are very good also.

BeQuiet. BeQuiet does have a few decent models, BUT, you must be VERY selective about which of their models you put your trust in. From model to model their are huge differences in both quality and performance, even with the same series. If you cannot find a review for a BeQuiet unit on HardOCP, JonnyGuru or Tom's hardware that SPECIFICALLY says it is a very good unit, and does not have any significant issues in the "cons" category, I would avoid it. In fact, I'd probably avoid it anyhow unless there is a very great sale on one that has good reviews, because their units are generally more expensive than MUCH better units from Antec, Seasonic, EVGA and Corsair.

EVGA. They have BOTH good and not very good models.

Not very good are the W1, N1, B1, B3 (Most models failed testing), BQ, BR, BT and G1 NEX models.

Good models are the B2, G2, G2L, G3, GQ, P2 and T2 models.

FSP. They used to be very mediocre, and are a PSU manufacturer like Seasonic and Super Flower, although not as well trusted based on historical performance. Currently the FSP Hydro G and Hydro X units are pretty good.

I would avoid Thermaltake and Cooler Master.

They do have a few good units, but most of the models they sell are either poor or mediocre, and the ones they have that ARE good are usually way overpriced.

This is just ONE example of why I say that. Very new and modern CM unit. One of the worst scores ever seen on JonnyGuru for a well known brand name product. Doesn't look to be much better than a Raidmax unit. Sad.

Cooler Master Masterwatt Lite 600W review

And most of the models I have linked to the reviews of at the following link are at least good, with most of them being fantastic.

Power supply discussion thread

The Powerspec units sold my Microcenter are a mixed bag. Some of them are fairly decent using the same platform as the Sirfa High power astro lite platform, so not total dumpster fire type units, but not particularly good either, and some of their units are simply garbage and should be listed below in the DO NOT USE category, but I'm leaving them out because there are really no reviews of them and since there are a few units from them that are ok-ish, I'm giving them a "use at your own discretion but buy a better model if you can" grade.

A gray label CX or CXm unit would probably be an upgrade from one of those Powerspec models, without any doubt.

Certainly there ARE some good units out there that you won't see above among those I've listed, but they are few and far between, much as a hidden nugget of gold you find in a crevice among otherwise ordinary rocks and don't EVER assume a unit is good just because of the brand.

If you cannot find an IN DEPTH, REPUTABLE review on Tom's hardware, JonnyGuru, HardOCP, Hardware secrets (Old reviews by Gabe Torres), Kitguru (Only Aris reviews), TechPowerUP, SilentPC crew or a similar site that does much more than simply a review of the unboxing and basic tests that don't include reliable results for ripple, noise, voltage regulation and a complete teardown of the unit including identification of the internal platform, then the unit is a big fat question mark.

I recommend not trusting such units as companies generally always send out review samples of any unit they feel is going to get a good review, and don't send them out if they know they are going to get hammered by the reviewer. No review usually equals poor quality. Usually.


Other models that should never be trusted OR USED AT ALL, under any circumstances, include

A-Top, AK Power, Alpine, Apevia, Apex (Supercase/Allied), Artic, Ace, Aerocool (There might be one model worth using, but I'd still avoid them.), Aspire (Turbocase), Atadc, Atrix, Broadway com corp, Chieftech, Circle, CIT, Coolmax, Deer, Diablotek, Dynapower, Dynex, Eagletech, Enlight, Eurotech, Evo labs, EZ cool, Feedtek, Foxconn, G7, HEC/Compucase Orion, HEDY, High power, iBall, iStar computer co., Jeantec, JPac, Just PC, Kolink, LC Power, Linkworld electronics, Logisys, Macron, MSI, NmediaPC, Norwood Micro (CompUSA), Okia, Powercool, Powmax, Pulsepower, Q-tec, Raidmax, Rave, Rocketfish, Segotep, SFC, Sharkoon, Shuttle, Skyhawk, Spire, Startech, Storm, Sumvision, Tesla, Trust, Ultra, Wintech, Winpower, Xilence (Until I see a reputable review of a model showing different), xTreme (Cyberpower), Youngbear and Zebronics.

They do have a few good units, but most of the models they sell are either poor or mediocre, and the ones they have that ARE good are usually way overpriced.

This is just ONE example of why I say that. Very new and modern CM unit. One of the worst scores ever seen on JonnyGuru for a well known brand name product. Doesn't look to be much better than a Raidmax unit. Sad.

Cooler Master Masterwatt Lite 600W review

And most of the models I have linked to the reviews of at the following link are at least good, with most of them being fantastic.

Power supply discussion thread

The Powerspec units sold my Microcenter are a mixed bag. Some of them are fairly decent using the same platform as the Sirfa High power astro lite platform, so not total dumpster fire type units, but not particularly good either, and some of their units are simply garbage and should be listed below in the DO NOT USE category, but I'm leaving them out because there are really no reviews of them and since there are a few units from them that are ok-ish, I'm giving them a "use at your own discretion but buy a better model if you can" grade.

A gray label CX or CXm unit would probably be an upgrade from one of those Powerspec models, without any doubt.

Certainly there ARE some good units out there that you won't see above among those I've listed, but they are few and far between, much as a hidden nugget of gold you find in a crevice among otherwise ordinary rocks and don't EVER assume a unit is good just because of the brand.

If you cannot find an IN DEPTH, REPUTABLE review on Tom's hardware, JonnyGuru, HardOCP, Hardware secrets (Old reviews by Gabe Torres), Kitguru (Only Aris reviews), TechPowerUP, SilentPC crew or a similar site that does much more than simply a review of the unboxing and basic tests that don't include reliable results for ripple, noise, voltage regulation and a complete teardown of the unit including identification of the internal platform, then the unit is a big fat question mark.

I recommend not trusting such units as companies generally always send out review samples of any unit they feel is going to get a good review, and don't send them out if they know they are going to get hammered by the reviewer. No review usually equals poor quality. Usually.


Other models that should never be trusted OR USED AT ALL, under any circumstances, include

A-Top, AK Power, Alpine, Apevia, Apex (Supercase/Allied), Artic, Ace, Aerocool (There might be one model worth using, but I'd still avoid them.), Aspire (Turbocase), Atadc, Atrix, Broadway com corp, Chieftech, Circle, CIT, Coolmax, Deer, Diablotek, Dynapower, Dynex, Eagletech, Enlight, Eurotech, Evo labs, EZ cool, Feedtek, Foxconn, G7, HEC/Compucase Orion, HEDY, High power, iBall, iStar computer co., Jeantec, JPac, Just PC, Kolink, LC Power, Linkworld electronics, Logisys, Macron, MSI, NmediaPC, Norwood Micro (CompUSA), Okia, Powercool, Powmax, Pulsepower, Q-tec, Raidmax, Rave, Rocketfish, Segotep, SFC, Sharkoon, Shuttle, Skyhawk, Spire, Startech, Storm, Sumvision, Tesla, Trust, Ultra, Wintech, Winpower, Xilence (Until I see a reputable review of a model showing different), xTreme (Cyberpower), Youngbear and Zebronics.
Thanks, that reduced the amount of PSU that i am concidering to three. Unfortunately, none of them has rewiews in that sites (al least i cannot find them, but i will keep looking).
-Gigabyte PB500 500w
-Sentey SNP550-HS 550w
-Xfx P1-500B-XTFR 500w
 
I'll be honest. None of those units is worth a crap.

There has to be something at least halfway reliable available to from Corsair, Antec, Seasonic, older XFX, Super Flower, FSP or even Thermaltake. All of them have some crappy models, but all of them also have decent budget models and then some excellent products as well.

Those XTFR units from XFX are poor quality, most of the Gigabyte units are not particularly good (Although they DO have a very few that are ok) and Sentey only makes maybe one unit, ever, that I'd be willing to look the other way on if somebody bought one. And that one isn't it.

I know that's not what you want to hear, but unfortunately, that's the truth.

I know this is late, but I think I know what's the thing.
I've read a magazine about a build with a Sapphire Nitro+ RX 570 4GB. I did not know, but this model has one 6 pin connector and one 8 pin connector. The PCIe slot deliveres 75w, 6 pin delivers 75w and 8 pin delivers 150w. Now you have up to 300w that the card can use, so 300w : 12v = 25A.
Note that this is the Nitro+ model with 2 power connectors. If I'm right, Pulse should have either one 6 pin or one 8 pin.
For PCIe slot add 6.25A, for 6 pin add also 6.25A and for 8 pin add 12.5A an see what you get.

I am going to buy from Mercado libre which is an online store of the country, of course with the currency of the country. To put in perspective: the Fucus+ cost aprox. $12000 and the Xfx cost $4000. The video card (used) cost me $7000 and i have a low amount of money for the PSU now, aprox. $4000.
In your budget you can get Corsair CX450, but that might not be enough.
If you can go over the budget a bit, this Corsair CX550 would be a better choice.

Thanks for the previous comment, i understand now how a card can consume 25A. In regard to the PSUs that you recommend: their are not possible to find local (in the country).

I think i will buy the Gigabyte PB500, i know is crap but i have no choice more that the three that i mentioned.
