Hi there
I have an Asus PRIME H310M-C R2.0 motherboard & a seasonic 2500W power supply, using to mine 2 GPUs & also turning on several HDDs for farming, anyway everything was ok, specially the ability that PC turns on automatically after a power loss as in my country power loss happens seldom, but today I wanted to replace a new motherboard, which was actually an older model and at the end I switched back to same Asus H310M, but when I wanted to replace the MB I didn’t shut down PC properly in windows and just pulled off PSU cables including 24 pin MB & 4 pin CPU cables right while the PC was on! Well I did that before specially with GPUs and there were no problem after restarting, but this time I noticed system shut down but didn’t turn on when I manually used a screwdriver to shorten the motherboard 2 pin power switch, I thought maybe I damaged MB, tried the older MB but same issue, then tried another much weaker 380W PSU and it worked.
But I simply couldn’t accept I have destroyed the costly 2500W Seasonic PSU so I played a lot with it and now I know if I switch off the PSU button or just unplug it, and replug back it won’t turn on automatically as it should and I have to touch the MB 2 pin switch buttons for about 20 seconds and it turns on in most of the times!
It turns on and work fine without shutting down so I assume no damage has happened, also I noticed if I shut down it properly using windows 10 shut down menu, It will turn on immediately as I shorten the 2pin, but it won’t if I switch it off or anything else to simulate a power loss.
There are many times I am not here to do this and I really need the feature that turns it on after a power failure, so please any help and advice is appreciated to know what is really happened? Is something in PSU has damaged? I really can’t afford to buy another PSU like this.
Thanks guys
