Windows 7: Is it possible my PSU is Maxed out

Is it possible my PSU is Maxed out

Here is the run down guys and gals

I recently stabilized my oc to 4.8 Ghz I have 2x HD7970's and also 850 w corsair gold PSU

now I was gaming and all of the sudden I just shut down out of nowhere the system was kinda warm but I felt the Psu it felt warmer then usual so I let my rig chill for a bit then it came back on fine

I didn't see any problems with heat when I did this overclock I ran IBT with 5 passes max temp 54c my ceiling is 61c and when I previously played the same game for a while my temps only were at 33c so is it possible my PSU is starting to tap out because of too much stress and if so i am going to replace it asap

Ps my V-core is flexing on different voltages and i have on llc so it should be solid

When you say just shut down, do you mean your game shut down(crashed) or your entire system shut down? If you were previously at 4.7xxGHz and went to 4.8GHz, I'm almost sure that didn't make or break anything. I also don't think the AX850 is being stressed, unless something is physically wrong with it. I would find a program that stresses CPU and GPU.....I think Furmark has such a program, and run it to see if you can reproduce the problem.

I was going to suggest the 1000 watt, but you beat me too it.

But shouldn`t the 850 be sufficient ? I thought today`s cards were supposed to be real energy efficient. Although, don`t your cards use 2 8 pin connectors.

Run 3D Mark ?

It is possible. This says around 625 recommended (575 minimum),

May have missed a component or two.

One thing, how old is the PSU? If it is a couple of years old, it could be down to capacitor aging.

That's the thing though i did a few stress test and everything but it completly shut down and the PSU felt hot meaning it had to heat up

This is the first time this has every happened even with a bad overclock it never shut down like that

and if you see the v-core reading they are different across but before they were all solid on the same voltage which has me beliving im stressing it out and my cards are clocked close to max as well

recently finished the whole tomraider at basicly the same speed and never had a single shut down or gpu issue only when i played darksiders 2 it would heat up like crazy

I used that PSU calculator and got 602 Watts MIN and 652 Watts MAX. I still don't think your PSU is being overworked. I would bet on the CPU OC before the PSU.
