Hi all, my current system is becoming a PSU graveyard and i'm not sure where to go from here.
Specs:
i7 4790k stock (Never got around to OC'ing it)
Corsair H105
Gigabyte GA-Z97X-UD5H-BK
16GB HyperX RAM
MSI GTX980
Lamptron hardware fan controller
PSU #1: EVGA 850 G2
PSU #2: EVGA 750 GQ
PSU #3: Corsair CX750
Timeline of events:
April 2018: My PC starts losing power randomly. No BSOD, no shutdown sequence, no warning of any kind. As far as I could tell, the power losses were completely random; sometimes it would drop a couple minutes after booting, sometimes I would go a week with no issue. All temperatures and usage seemed more than fine. Nothing in the event viewers logs other than a generic Kernel Power 61 error. After a couple of weeks, the PSU started making noises that no PSU should ever make, so I replaced it, and everything seemed fine.
Three weeks ago: Same thing started to happen again. Randomly dropping power, no BSODs, no error message, no warnings. Seemed a huge coincidence but I had stuff to do so change the PSU.
Last week: Same thing happened again with a two week old PSU. I found mention somewhere that USB ports could possibly pull too much power, so I disconnected my cases' front panel USB hub. The machine successfully idled without fail for two days, then yesterday morning I booted it, it was on for maybe 30 seconds before shutting off, and it won't boot again.
During this time I have tried using the machine from different wall outlets, and I have tested the wall outlets and they all seem fine. I popped the CMOS to reset it, tried each RAM stick independently, tried booting without my GPU installed. Tried different cables, reseated everything etc. The lights on my motherboard are lit up when a power supply is connected, but trying to boot just produces an audible click and nothing else.
I don't know what to try next. PSU #1 i'm not plugging in under any circumstances, and PSU #3 appears to be totally dead. PSU #2 might still have some life in it but in the current situation it doesn't look as if it will last long if I power it up with this machine. I don't have an alternate machine to test the PSUs on, and my friends won't let me anywhere near their rigs with my cursed power supplies.
Any suggestions?
