I have had the RP650-2 for a few years now, I'm not entirely certain for exactly how long.

I just wanted to ask, do you think that it is decent, and do you think it is possible I could be having some problems with it now?

I ask because I have been having graphics problems where the screen, during a game or something similar, will go black for ten or so seconds and then the screen will return to the game. I went through a bunch of other troubleshooting and some people have suggested that my PSU may be the culprit, in that it may not be supplying enough power to my graphics card.

This recently became a problem when I upgraded from the geforce 460 to the 670. So, I guess I am mostly asking whether or not my PSU is powerful enough to run the new card.

Here are my other specs in case you need them too:

MSI 790FX-GD70 motherboard
AMD Phenom II X64 965 3.4ghz quad core
F3-12800CL9-4GBRL (x2)
Galaxy GeForce GTX 670
then just a HDD, cd-rom, usb keyboard and mouse, and monitor.

None of it is overclocked - except for the factor oc on the GPU, but I have reduced that to normal, even below, and not had any change.

Thanks for the help!

That Rosewill has plenty of power on the 12V rails, which is what a GPU feeds off of.

Rosewill is a Newegg brand and is decent but nothing I would buy as building PCs is my hobby so I tend to put more money into my parts.

That said, it could be the culprit but you need a test PSU to be certain. It could also be the GPU is bad. You state it is only during load. Have you noticed any artifacting or weird glitches that are not normally there? Also, is the GPU new, used, Open Box etc?

The GPU is brand new, but I don't think it is the culprit. I put it into a new system entirely where it ran fine and I ran a few benchmarks on high settings, and did not have any problem.

Also, no other problems at all, just the black screens under load.

I'm not too sure how to test the PSU, and I don't have any kind of PSU tester... I suppose I may need to buy one or find someone with one to test it.

I have a 550W in another computer (don't have the model on hand atm), and the 670 says a 500W is recommended, do you think that would be something I could test on the system to see if the problem is in fact my PSU in my computer?

I hope that makes sense.

In other words, would that be an effective test to see if my current PSU does not work effectively? Meaning, if the replacement works, does it mean my current PSU does not?

So I just tried it by switching the PSUs but the same thing happened, the black screens.

I have no idea where to go now.

I've tried different ram, a different hard drive,a clean install, overclocking/underclocking, different PCI slots with the GPU.

The only thing I have yet to really try is updating my BIOS. I am only hesitant to do it because I never have before and don't want to screw it up. Also, I looked at the updated version of my BIOS and all it says is: "updated AGESA code." Which as I understand would not necessarily help me at all.
