PSU tier list 2.0

[turkey3_scratch]

In any freeze where you can ctrl-alt-del out of it it's always software related. A hardware freeze is permanently frozen, you ain't getting out of it.

@logainofhades: CX750M worst of the bunch? It was always a more modern design than the others with DC-DC converters. The lesser-wattage ones were group regulated. That alone makes it better.

I tried to Alt-Tab out of the game but that didnt work. So i could only Ctrl-Alt-Delete out of it . Probably his graphics card. We popped it in my system due to it stuttering in his system.

For some reason I doubt that. If you can ctrl-alt-del out of a game it's just a software freeze with the game. One misplaced byte they said. It will freeze they said.

But Windows is designed so that a freeze with one program doesn't freeze the whole OS like it would in the 90s.

The hardware of a computer does not communicate with the PSU at all. The GPU does not say to the CPU, "cough cough this voltage sucks, what say you we tell ol' volty to step up the game, and if he doesn't let's just quit performing well". The only thing the CPUs and GPUs do are follow their orders, and frequency does not lie. Frequency is in 1/ s or Hz. How many cycles per second, each cycle an instruction or part of a big instruction is executed. The PSU does not have any say in slowing down or speeding up these cycles, only if they function or not, and if the PSU causes it not to function it's pretty much a whole system freeze that won't be fixed by ctrl-alt-del.

Lets keep it to power supplies guys. To diagnose an issue start another thread.

From the JG review.

What we have here today, for most of us enthusiasts, is a decent performing 650 watt unit with a 750 watt number on the side.

That alone is enough for me to say avoid.

The new version may be the same platform, but it appears that improvements were made to it, to make it a decent unit.

Don't just skip to the end though. It only happened since Oklahomawolf was basically cooking bacon into the fan. In any normal case these days where the PSU fan sucks in air below the case it should handle 750W well without over-temperature protection cutting in.

Plus since the mentality of most people here is don't run a PSU at 86.6% load all the time, what harm is it anyway then in a system using less than 650W??

Nice find. The Disassembly page does indeed show the same platform so it's just a refresh.

So the question was a CX750M v2 vs a Seasonic G 650w?

I'd take the Seasonic.

 

[Jeff_116]

Anybody know if the NZXT Hale82 V2 550W is still 2B/3? I'm only powering a single SSD, i3 6100 and gtx 1060 3GB, but I really want to continue my white theme with a white modular PSU(there's even a white cable option too!)

 

[BalorGr]

Are we sure 750GQ is tier I ?It gave bad ripple results.

 

[CurnRaisin]

Should I pull the trigger on getting a HX850i while its on deal (only 10 left in stock), or wait to see if a AXi(or another other high end Seasonic OEM) model goes on sale but run the risk of losing out on the HX850i deal. Will me as a user really notice any difference, since they are both top end? Or if anyone has other suggestions for a PSU around the £120 mark please speak up.

 

[superninja12]

@jeff, no its a bad psu. consider the superflower leadex gold (its white)
@Balor take the list with a grain of salt, yes its actually not tier 1 but tier 2 imho , nevertheless its a super stable psu
@curnraisin get the hxi its a fantastic psu.

Ordered. Thanks for helping me decide, I would be still here next year waiting on new deals ;p

Since people in this thread know their shit on PSUs. I am helping my friend fix his younger brothers PC, now this is a hand-me-down pc from a few different sources and a new GPU he got for his birthday:

i7 920,
4GB DDR3, Soon to be 8(2x4GB)
1TB HDD
R9 8GB 390
2x140mm Fans

Long story short his old PSU blew, then the "new" one his Dad got off ebay for £20 (no big surprise) also failed the test. Any way since his younger brother literary has no income, it will their parents paying for it, what is the cheapest PSU you can suggest to make do.

 

[logainofhades]

Evga B2 750 would be my pick. XFX 750w would work too. Those 390's are power hungry, and so is the i7 920. Hopefully nothing got damaged by using those junk units.

Yeah that is what I'm going to check first, make sure everything is working, before going and buying a new PSU. Really 750W,wow, I knew the 390 where power hungry but didn't think that much. I was thinking 600-650 to be safe. I will try and keep an eye out for deals over the next week.

 

[logainofhades]

A good 650w isn't going to be much different, price wise. Avoid any B1, Nex/G1 Evga. http://uk.pcpartpicker.com/products/power-supply/#sort=a9&e=4,2&W=650,2000&m=52,14,71,39

 

[turkey3_scratch]

Nobody said the 390 NEEDS a 750W unit but it will certainly put it at 50℅ load about when gaming.

Yea, with the pricing structure, a 650w isn't a very good deal, over there, when trying to save as much as possible.

 

[CurnRaisin]

Yeah I get what your saying, and I agree that a solid PSU is the cornerstone to any good PC build. But the problem is that the kid has 0 source of income and it will be his parents paying for it, and there is no way they will want to fork out the cash for a "good" psu, so I was looking for the best of the worst sorta thing. I guess I can just tell them to get good model and wipe my hands clean of the situation, then they can get what they want.

 

[logainofhades]

Get a good PSU, or watch the system go up in flames, that is their options. PSU is the single most important component, in the system.

 

[Mac070]

As long as you get a good brand then your pretty much set. I mean if you have a Corsair or EVGA PSU in a low tier take any components with it then the manufacturer will replace everything.

 

[Onus]

If they just saw one go "bang!" hopefully they will be receptive.

Care to show us a line in the Corsair warranty that states this?

 

[Mac070]

Don't know if they state this or not but I know people who have experienced their Older CX PSU's going out or even catching on fire taking everything with it. As long as you have evidence like a video or send in all the dead components then they will replace them.

Also Salazar Studio or Science Studio on Youtube had an incident where his PSU killed his components and they sent him a better EVGA P2, which was better than his original one and replaced all of his components.

If you've never heard of this then you must be living in a cave 😀 Lol

Replacing some youtube dudes stuff is simply good PR. And sending a better quality part IS in their warranty terms.
You and me? That's a whole different story.

And, while I do not live under a rock, neither do I follow the bobbleheads on youtube.
I have no time for crap information.

 

[logainofhades]

I must be a cave dweller, as I have never heard of any such thing. Never heard of those channels either. I have better things to do, than spend all day on youtube, though. 😛

 

[Onus]

What a vendor might do, and what Corsair is obligated to do, are not the same thing.

 

[Mac070]

Well you guys need to live a little lol. Never watched Tech channels or so called "Bobbleheads" on Youtube like Techsource, JayTwoCents or TechOfTomorrow. They didnt just replace the components since he was a Youtuber. EVGA or Corsair would have done it for any regular person.
