I need help determining if my OCZ ZX 1000w PSU is faulty or if Newegg sent me a second broken Gigabyte R9 280X. I used OCCT to test the PSU and these are the results for the 12v, 5v, and 3.3v rails which I'm assuming are the important part. 11.68-11.78v, 4.88-4.91, and 3.13v. I got the results after a 30 minute long test and I'm hoping someone can confirm that the PSU is fine. Here is a link to my first thread in Graphics and Displays,http://.

Bump/Update
I'm pretty sure the GPU is broken but can anyone confirm from the results above that the PSU is fine? I've been using it with my HD7770 for about 3 months without a problem.

Voltages have a tolerance of + or - 10% which means they can be off buy up to 1.2V (on the 12v rail) before theres a problem. All your voltages are well in that range so no problems. Why are you worried? Do games crash or something?

The frame rates are really low and most of my games freeze after a few minutes with the 280X. It's the second 280X that I've had this problem with and somebody in my other thread said it could be the PSU.

It could still be a PSU problem, just because voltages are normal doesn't mean the unit is good. OCZ units aren't bad but it's still possible to get a dud.

How can I check to make sure the PSU is fine? HWMonitor and Gigabyte OC Guru both show 1.2v for the card under full load.

unless you have a oscillator, you can't. You can check voltage with a multimeter but again it'll only tell you so much.

Do you think it's very likely that the PSU is the problem?

Is there anything I can look for in the OCCT results that that would point to the GPU as the problem? Are there any other programs that might help?

There's no software that is going to tell you if you PSU is bad. I would try a different unit although it could be just as likely that you got another bad GPU

Honestly I don't really care for OCZ units, they're overrated and much higher quality units are only a small price difference away. Try a Seasonic X series, it's the best unit on the market right now hands down. You don't need 1kw for a 280x not even for 2 of them.

I bought the PSU before I had picked out a GPU and I knew I was going to do a SLI or CrossFire build. There isn't any software that can monitor how much power the GPU is getting?

To my best understanding with the atx specs that only goes for the negative rails like the -12volt,but for the positive rails the tolerance is a max of 5% which means that the value of 11,68 on the 12voltrail is getting close to the minimum limit and 3,13 volt on the 3.3 rail is under the minimum.

Those read outs are by the way all very low imo.

@ WhatamIdoingWrong,

The program hwinfo32 can make a log, for this you install it,open it,in the first window check=V sensors,in the next window on the bottom click "logging start" and choose a name and place for the log like hwinfolog and desktop.You might do some heavy loading like with prime95 or furmark.
This wiil keep on logging until you stop it,leave it running for a good period like a half hour up to 2 hours.You can read the log by opening it with either excel or libre office calc.

In the end it's only a software read out but it might give a hint wether the psu is faulty and it will give info about the cpu/gpu too,like temps and voltages.

HWiNFO is showing 12.15v, 5.01v, and 3.26v.

Those values look good,but like i said it's a software tool,using a multimeter would be better.

A log like i explained would show fluctuations in those values over a longer period or keep the program open for a longer time so you can keep an eye on the minimum and maximum values.

I got an XFX 280X Black OC Edition a few days ago and I can max out all my games at 1080p now except for Far Cry 3 which doesn't get along with something on my PC. I know Gigabyte is supposed to be a pretty good company so I'm surprised that I got 2 duds from them. Thanks for the help.
