So I’m wondering if my psu is bad. Yesterday I was working on stability testing my cpu and the system just abruptly shut off and would not turn back on. If I flipped the PSU switch off and left it off for a few seconds then flipped it back on and pressed the power button my rig would turn on the immediately shut off. I kind of panicked and thought I fried my cpu but my vcore is at a conservative setting of less than 1.3V. I tried the trick of shorting two of the pins on the 24pin connector and the psu turned on and stayed on. So I thought it was ok. Plugged the 24pin connector back to my mobo and tried to power on and it turned on (didn’t post because I had the cpu power pulled and no ram). Put everything else back in and it posted and booted just fine. Had no issues for the rest of the night. Well now today I’m having the same issue. It started with a few BSODs and shutting off but allowing me to power back up so just to be safe and eliminate variables I tried setting all my clock speeds back to stock but before I could do that it shutoff again and will not power on. I even tried shorting out the 2 pins on the 24pin connector and the PSU flicks on then immediately off.
Anyways any help would be much appreciated and I’m hoping I didn’t kill my cpu… (I did try powering it without the cpu power again to see if it would try to post and fail but it still immediately shuts off).
i7 8700k @4.9GHz with about 1.285V vcore
16Gb G.Skill Trident Z ram @ 3000MHz
Asus Maximus X Hero mobo
Asus Strix GTX 1070 Ti
Corsair H100i V2 AIO
Corsair AX1200i psu
What’s puzzling me is how I could have killed the PSU as it’s less than 2 years old and it’s WAY overkill for my system, however I did get it by RMAing my old original AX1200 to Corsair. My system draw in Corsair link is usually less than 400W. I know it isn’t filled with dust because the psu dust filter is practically spotless.
Anyways I’d appreciate any info and hopefully I didn’t kill my CPU as that would be much more pricey and a hassle to replace. Thanks!
EDIT: I don’t know if this means anything but after I got it to power on and stay on last night i was monitoring power draw / delivery in Corsair link and every so often it would say 0W output then go back up to it’s normal idle output.
