Is it really my PSU???

[Gregory1566]

I built my computer about 3-4 years ago, all premium parts at the time:

PSU- Corsiar TX-950W

Rest of the build
Twin gigabyte 6970's in crossfire
core i7-930
Gigabyte MB X58A-UD3R
12GB Ram

Lately any time I Play almost any game it crashes within a few minutes give or take, its stable all day long if i dont launch something gpu intensive. I have been reading about this maybe being a PSU issue, when it freezes i can still hear the audio for about 10 seconds, then the whole computer locks up and it needs a hard reset, lately it seems to be getting worse and worse, i dont have another power supply modern enough to power my system to see if thats the issue, i was wondering if ordering one is worth it, and if anyone had any suggestions for a good PSU(money not a major concern) if i should need to order one. All i have read online points to a potential power issue, but id hate to spend 200 to find out one of my video cards is toasted... any help is appreciated

FYI, I have good cooling on CPU/GPU and the whole case, temps have been fine

What are your sources for this information?

Try a game with just one card. Then try just the other.

I would run a hardware monitor for your system, something like MSI's afterburner, then run whatever again, and have afterburner log the data.
Also, would run CUPID HWMonitor and see what voltages it is showing, and make sure they are all in spec.

I found something called CPUID at http://www.cpuid.com/softwares/hwmonitor.html.

@Elixer: Is this what you meant?

Yes, that will show your voltages...

@Elixer: thanks for confirming.

My problem appears to be similar to the original post in this thread. My Windows 7 PC often shuts down suddenly during graphics-intensive game play (like Steam games). Additionally, it has of late developed a problem of not shutting down or restarting. I have to do a power off from the back (PSU) to reboot it. Also, in a somewhat bizarre development, I was not able to open Google Drive's initial dashboard on Chrome (I recently moved to the "new and improved" dashboard!). It, however, worked when I disconnected my second monitor and restarted the system.

All of these problems seem to suggest that my PSU (Rocketfish 700W purchased in 2008) is either not able to bear the load of my GPU (AMD Radeon HD 5750), or it has started breaking down for other reasons. It seemed to work fine for several years. I was wondering if there were any suggestions on a good PSU or how to estimate my requirements. I have a decent load of peripherals connected via USB but nothing major. Any help would be greatly appreciated.

There's your problem right there. ("Rocketfish PSU")

Get an Antec, Corsair, Seasonic, or Enermax. Should clear up the problem, that is, if the crappy PSU didn't damage any of your components, which is a possibility.

What are the voltages showing for your rocketfish ?
Seems that this is made by huntkey. http://www.hardwaresecrets.com/article/Rocketfish-700-W-Power-Supply-Review/556
