[SOLVED] Is this PSU(picture of the specs in post) good enough for an ASUS DUAL RX 580 8GB ?

[peckata2]

https://photos.google.com/share/AF1...?key=S1VDTzZfcWpZaW5acEJYb1Q5cHZqWGpYLTlzem9n its a Cooler Master brand.
Can a PSU with these specs power a RX 580 specifically this version https://www.asus.com/Graphics-Cards/DUAL-RX580-8G/ ? I have used this PSU with an R9 270 for 6 years.
link to the specific r9 270 I was using: https://www.asus.com/us/GraphicsCards/R9270DC2OC2GD5/
What are the differences between these 2 GPU s in power requirements (not talking about watts) ?
I don't understand any of the specs on the PSU other than the power output (watts) any explanation or link to a guide would be very much appreciated.
ps. If it matters my CPU is an intel i5 4670k (running on stock clock not overclocked at the moment)

Well, it is not that complicated -
most todays GPUs use 12V input and adapt it to their needs using VRM. You can find out if the PSU can supply sufficient 12V output power by taking the card power in watts and dividing by volts (/12) to get Amps. Then checking the PSU PCIe rating in Amps (usually right there on the sticker). Now you have to leave room for the CPU and HDDs which also use it in a similar manner (W=V*A). A nice table here.

So the CPU and HDD also use the 12v?

That's a 250w PSU at best(only 20a on the 12v rail). It is not going to power a RX 580. The fact it has managed to power even a R9 270 that long is next to miraculous.

In a modern system the 12v rail is the most used and most important. Many if the big OEMs use 12v only power supplies and Intel is even working on a ATX12VO(12v only) spec.

The tdp diffirence is 30 watts between these 2 GPU s

 

[vov4ik_il]

CPU is powered through VRM which takes 12v in most cases. Desktop HDDs usually use 12V for the motor and 5v for the logic board. Fans and water coolers - 12v, USB controllers, memory controllers, SSDs, most low power peripheral devices use 5v or 3.3v.
Now if a device (say CPU) states it is 95W, it is up to an average 95W dependent on usage.

Thermal Design Power(TDP) is not a measure of power usage, it's a thermal/cooling spec. If you read some reviews the RX 580 can use ~200w by itself and has high transient loads. For a RX 580 you want a good quality 550w PSU, not some bargain bin 500w PSU that has a misleading(straight up false) rating like you current have.

What about this one? https://www.bhphotovideo.com/c/prod...r_mpw_5001_acaan1_us_elite_v3_500w_power.html
Can this power the rx580 and an i5-4670k?

 

[bignastyid]

While better than what you have it's still low quality and not a good choice for a 580. Cheapest unit I would use with a rx 580 is a CX550. However with current prices you can get a Antec earthwatts gold pro for $1 more.

Well those arent available in my stores and also i have a very limited budget and want to get a gpu quickly cus the one i had isnt functional anymore
What do you think of this compared to the other one?

That unit is junk. A cheap PSU can end up costing you alot. The PSU is a very important part as a poor quality one can destroy other components.

What sites are you looking at buying from? I can look through them and possibly give you some options.

Ow and btw if you think I cant stay withing budget with an rx580 and a PSU suggest anothet GPU with close performance and with or without a new PSU

You are putting the 'cart before the horse'. You want a gpu so you can get back to gaming, thinking that the gpu is the priority. It's not. The psu is. You can get a really sweet gpu that'll get you great fps and a really good picture, at the cost of not having a usable pc since the psu is garbage.

Much better to get a decent psu that'll actually work, and work well and settle for less than stellar graphics.

The psu is the only corner that should never be cut. Ever.

Would it be fine to use a ASUS DUAL GTX 1650 4G as its TDP is very low with my current PSU ?
From the advice that all of you gave me I can see that I need a good PSU if I want to get a RX 580 or similar GPU in performance and power consumption and I think the combined total of a good PSU and the RX 580 would be over budget for me as money is tight with the pandemic.

NO NO NO NO NO NO NO NO NO!

You are LUCKY that PSU lasted that long.

That PSU is so cheap, Cooler Master refuses to put their own name on it (Thermal Master is Cooler Masters low end... if you can believe there is such a thing!)

• Hardly any power: 12V X 20A = 240W. Hardly anything uses +3.3V and +5V so who cares if the addition of those even makes it a total of 500W.
• Passive PFC. Where did you even FIND that PSU? Anything but active PFC is "illegal" in most countries because it puts too much strain on the grid.
• No safety certifications. The CE is probably fake because to meet CE, you have to meet certain efficiency standards that this PSU does not have. (Edit: It could mean "China Export": https://support.ce-check.eu/hc/en-u...-Real-CE-Mark-From-A-Fake-Chinese-Export-Mark )

And I won't even get into the technical aspects such as the topology, regulation, lack of protections, etc.

It is not "safe" to use that PSU to power a potato.

It came with the case k380 in a bundle was very cheap considering I get a Cooler Master PSU with a good looking case I got at the time I had almost no info about the PSU after I made the purchase I saw what it looked like and the specs of it.
Could you give me some examples about the trouble this PSU could cause ?
PS Don't take this question the wrong way I believe what you say is true I just want to understand the problem better

The facts are surprising.

In 2007-2011, there were an estimated 730 reported U.S. home structure fires involving office equipment per year, resulting in:

11 civilian deaths per year
51 civilian injuries per year
$28 million in direct property damage per year

48% of the time, a computer was the cause of the fire.

That's exactly where continued use of your current power supply is probably headed. It's a real thing, it's no joke, it's not an exaggeration.

I actually wonder if Cooler Master set up Thermal Master as a separate shell company that they can fold up at any time if someone tried to sue them for burning their house down.....

All of the feedback you guys gave me was very useful so far but I still need help deciding so could you please keep replying ?
Thanks in advance
How about this PSU with an RX 580 ? http://www.deepcool.com/product/powersupply/2017-10/10_7115.shtml

If Deep Cool is a good option in your country, at least consider the DA500: http://www.deepcool.com/product/powersupply/2016-06/10_5493.shtml

That one is not available, but what do you think about the one I asked about is it good for a RX 580 ?

This one should probably make the cut. While not perfect, it should provide well enough power for AMD RX580 and i5 4670k.

Goodness no.

That one is arguably worse than the Deep Cool he was looking at!

 

[jonnyguru]

From that "Setek" site, this is the cheapest I would suggest: https://setec.mk/index.php?route=product/product&path=10019_10020&product_id=22742

That's a VERY good power supply. Probably more than you want to spend. But that site doesn't have a very good selection.

I'm surprised how much stuff they sell that would be deemed "illegal" in other countries because they don't meet local regulations. I guess Mecidonia doesn't have any kind of safety certification body.
