650w PSU WITH R9 290 OC EDITION

[MDR3VO]

will a 650w psu work with an asus r9 290 OC edition gpu

Specs
Intel i5 4460
8gb ram
Vs650 corsair
1tb hdd
Asus r9 290 oc

Yes it will however just beware the Corsair CX and VS series have a lot of issues, moreso the CX than VS. So while it will work, if you begin to notice stability issues or crashes its likely your PSU, not because of the wattage, but the brand/model.

Is the coolermaster g650m good and stable

As per above its not bad, but then talk about capacitors has them worried about its longetivity. EVGA, Seasonic, and XFX all have PSU's without this issue. If you can find yourself an EVGA GS, G2, or B2 unit, or an XFX TS or XTR those would be better ways to go.

Would corsair TX series be good

 

[Rogue Leader]

I would get the Coolermaster over that.

 

[MDR3VO]

Would that do for my system e.g no more crashing and stability

 

[GhislainG]

Do you already have the Corsair VS650 and the system is unstable? There was no mention of stability issues in the OP and the motherboard was left out.

 

[MDR3VO]

Yeah I do and I have stability issues with my r9 290. bearing in mind that the psu was bought a few days ago new. When I down clock the GPU it works fine.

 

[GhislainG]

Even though it certainly isn't the best PSU, it provides up to 600W on the 12V rail. If I understand correctly, the overclocked GPU works fine when not overclocked. The PSU is new, but what about the GPU? If not new, what was the previous PSU and did you have the same issue?

 

[MDR3VO]

This is a new build and the card is factory oc no previous psu

 

[MDR3VO]

My mobo h81m e33 maybe incompatiable

A GPU becomes unstable because of too much heat, or lack of voltage. Now we know heat isn't the problem, so if a factory overclocked card is having voltage issues either the PSU doesn't put out enough voltage, or its not of the best quality. That PSU is rated for enough, so that leaves us with the last conclusion. The PSU is low quality and having issues.

Replace it, with the Coolermaster, it should solve your problems.

 

[GhislainG]

Unlike Rogue Leader I believe the issue is with the GPU, but both are possible.

 

[MDR3VO]

Could you tell me why you may think that it may be the GPU (just wanna know)

Because it works fine when you down-clock it; that doesn't significantly change the power requirements, but it runs cooler. In the end it's up to you to decide if you RMA the GPU or buy a different PSU. If you buy a new PSU and you still have the issue, then you'll know for sure it's the GPU. Do you have issues when stress testing the GPU?

 

[MDR3VO]

artefacts appear one sec before it crashes with a blue screen in game i think the same thing or worse with happen when i stress test

 

[Rogue Leader]

Artifacts are from too little voltage, however crashes are from heat. Its a combination of issues.

I would say your PSU is definitely a problem, and I would change that before seeing if the GPU is also the issue.

I've never seen artefacts be caused by the PSU; they always were caused by the GPU being clocked too fast and/or overheating.

Yes, not enough voltage for the clock speed set. Heat causes it to straight up crash.

 

[GhislainG]

How often have seen that in your career?

 

[Rogue Leader]

How often have seen that in your career?

Any time you over clock something too much without increasing the voltage accordingly.

Or when a PSU can't put out the power needed.

 

[GhislainG]

You can increase the voltage on the GPU, but not on the PSU. The GPU should work as released by the manufacturer; the OP shouldn't have to down-clock it or increase voltage. If the PSU didn't provide 12.0 volts ± 5%, then other issues would also occur. The OP will have to determine if the PSU or the GPU is defective, but I still bet on the GPU.

 

[MDR3VO]

Does it matter that the cards minimum power requirement is 750w
