    psu failing....possible damages??

    Hey guys, first time posting. Ill start from the begining. I had a cooler master GX-II 750W PSU, and MSI 970 GPU. I noticed that the 970 had a really bad coil whine during 3Dmark ice storm benchmark, which i had never heard before, so i swapped it out to the ASUS Strix 970 GPU. I still noticed it afterward so i looked closer at my PSU. I found after start up at idle, it was floating at about 11.9 volts. During a CPU stress test i saw the voltage fluctuating at about 11.83 volts, and when i ran a Furmark Test during the CPU's stress test, i saw 11.7 volts. This was Done at stock CPU/GPU settings. So i went and picked up an the Corsair AX860 and the Fluctuating Voltage has disappeared, It is a stable 12.X now.

    I was curious if the undervolting from the Coolermaster PSU, possibly caused higher current draw and damaged more than just the GPU. I know that coil whine can be caused from either crappy coils, or low amperage on the 12volt rail. I haven't been able to reach my OC's that were once stable. I have had crashes/BSOD during simple CPU/GPU benchmarks/Stress tests. I just haven't been able to figure out what I'm chasing. Could i have effected the stability of my circuitry on the MotherBoard. Its only about a week old, or possibly the CPU's stability with the integrated voltage controller?

    Thanks everybody
    My current set up is:

    Intel 4790k

    Asus strix 970
    Pny ssd 120gb

    So you have a UPS that can carry the actual AC current wattage for your PC. If not, get it and add wattage for your Cable Modem, Routers, Switches and LCD or HDTV

    Hello bbaxter18, welcome to the ROG forum !

    Sorry to hear you're having issues.

    Try resetting the bios to defaults and start over with your overclock, let's hope your previous psu hasn't done any damage.

    @sk2play - im sorry that wasn't simple enough for you to understand, i will be sure to edit my post once I'm not on mobile.

    @nate152 - I've gone back to defaults, and slowly stepped up to my original OC's, failing before i reach them. I used XTU in the past and had profiles saved as well but i cannot get the pc stable when using the higher ones that were once stable. All of my gear is under warranty and the processor itself is only maybe 2 months old, all the other components are younger. Im not worried about needing to return them i just dont want to take brand new gear back that isnt truely bad. I guess what i am after is maybe some help troubleshooting to identifiy problems with the motherboard Or processor if any exist.

    All right

    Have you updated to the latest Nvidia driver 352.86? This could help with the gpu crashing.

    Tell me your settings you previously had for your highest cpu overclock.

    Yes the latest Driver has been updated, in fact the GPU has yet to fail, I revised my OP to explain it better, but Ive had BSOD and system crashes where the system just powers off during A GPU or CPU test. My highest OC, stable enough for a benchmark using 4.8~ @ 1.32V, 102 bclk. since swapping the PSU, i'm am having trouble benching 4.7 @100 bclk.

    All PSUs drop voltage a little under load. The core ATX specification allows a a +12V tolerance of ±10% (10.8V-13.2V), but most PSU manufacturers adhere to the ATX2.x "recommendations" for a +12V tolerance of ±5% or less (11.4V-12.6V). PSUs which meet 80 Plus standards (Bronze/Gold/Silver/Platinum/Titanium) typically require better design/components which intrinsically offer tighter voltage regulation.

    To be honest, any PSU these days which lacks Active PFC and can't offer (at worst) ±1% regulation is best avoided. It will be inefficient, hot, loud, and have to work harder to deliver the same power load, and the "dirty" power it outputs will be a lot more wear and tear on the (already hard-working) motherboard-integrated VRM circuitry.

    I think a 750W PSU would be the minimum recommended for your listed hardware.

    The GX-II was an 80+ bronze, i only replaced it because the symptom was still there after i swapped GPU's. When i would boot to Bios, i remember seeing it at +12.1 volts then as time continued, pushing the OC, i saw it on HW monitor in bios it fall to 11. I was monitoring my 12v rail with the multimeter as i began troubleshooting with stock settings, i saw the voltage fluctuate.
