I am trying to figure out if my PSU is on the way out...

I am not experiencing any crashing or anything like that, but I noticed in GPU-z for my 290x that under full load my volts will drop from 11.63v to 11.03v

how accurate or important is that 12v reading in GPU-z?
 
What PSU do you have?
GPUz pulls from the sensor. 11.63v isn't very strong either. I would be concerned about your PSU with those numbers.
 
its important enough to check the voltage with a meter.....that is a bit to low to ignore
 
My 290 voltage in shows 11.75 with no load, and 11.65 with a load applied. So it also shows a bit low, but not as drastic of a difference as yours shows. ATX voltage spec is 11.40 V to +12.60 V, so I would be a little worried about your numbers. Can you use a voltage meter? Is your PSU low wattage etc?
 
Mine shows 11.75v with no load .
Its better to use hwinfo for accurate info.
 
11.63v-11.75v on my 290x's. I had 3 mining with the same psu I'm using now. It's a silverstone 1200watt strider gold evolution. I don't think the gpuz sensor is accurate.
 
Sure enough..i upgraded my PSU to an Corsair TX-850 and now my 12V is rock solid at 11.63V (same number reported by others)

last week it got so bad it was dipping down to 10.5V on the 12v reading
 
Thermal Take TR600 (600W)

the reason I even started looking at this is I was getting black screens after playing a game and freezing in games and sure enough this fixed it :)

You are exactly right. My single 290, heavily OC'd to 1.275Ghz with +100mV, would show 11.65V when it was loaded 99% (Furmark) along with my 5Ghz 3770K (Prime95 AVX) to stress test. I ran that loop for 36 hours without a hiccup and voltage loads never wavered (I checked them with a higher end Fluke multimeter since my MB has checkpoints)..

When I added my second 290 and the same as above, the 12V still read 11.65V..These SeaSonic X850s (i have the V3) are bulletproof.
 
My 290x in 2D mode is 11.63v with a Corsair TX 950 that will be 6 years old come March.. my 290x is the Sapphire Tri X New Edition with 6 phase power design.

Im a little confused to what you implied? Your saying gpuz result was incorrect or was correct per what the fluke displayed?
 
My 290x under load show 11.63 to 11.33v in GPU-Z. Running furmark to see if voltages sag over time under load. I've been having instability issues after a cold boot when running my GPUs under load.
 
GPU-Z shows my 12V going to 10.88V when the GPU hits 100%, and Sapphire Trixx shows dips into 11v. I'm using an Enermax Maxrevo 1350w PSU on a RIVE mb - I'm a little concerned with these readings. Is my PSU on the way out?
 
GPU-Z shows 11.88v @ idle and 11.75v during heavy load. My psu is the Silverstone Zeus 1350w. Checked with DMM and my 12v line shows 12.20v solid.

Never had any issues with my 290 while gaming.

This is probably due to the resolution of the sensor. Like the next step up from 11.63 is 11.75 that it can display.

Sorry I didn't see your question Sean..What I was trying to say was that the numbers were correct, the 12V from the cards PCB was the same as the sensor..My 12V line itself was higher @ 12.15V (measurement from the Mobo checkpoint and also from a molex connector)..
 
11.4v to 12.6v is within spec on the 12v rail. If you start dropping below 11.4v, your 12v rail isn't delivering power to spec, and you'll lose performance....especially if your system / overclocks are power hungry.

That said...you should check it with a multi-meter, and not GPUz sensors tab.
