WindsFPS Posted July 27, 2021 Share Posted July 27, 2021 So like the title says I need help with the psu, everytime I click the power button it flashes on, like it turns on for a second then turns off, the cpu cooler, fans and things like that turn on for a second then off, it turns on completely when I hold it for a bit, is there a way to fix it to where it just turns on when I press the button, and is this harmful for my system?

Corsair Employee jonnyguru Posted July 27, 2021 Corsair Employee Share Posted July 27, 2021 That's not the PSU if we're talking about you pushing the button on the front of the case. The two pins on the power button go to the motherboard and then the motherboard tells the PSU to turn on. For some reason, the motherboard is not holding onto that power on signal. Maybe try updating your BIOS? Could be a known issue with whatever motherboard you're using. Link to comment Share on other sites More sharing options...

I've seen similar behavior on some Gigabyte boards with a backup BIOS. They'll do this when the (current) primary BIOS fails to POST ... it'll auto-switch to the backup BIOS and act very much the same. Disappointing that it didn't pan out. 😞 Link to comment Share on other sites More sharing options...

Corsair Employee jonnyguru Posted July 28, 2021 Corsair Employee Share Posted July 28, 2021 Does it only do it on a cold boot? In other words, if you shut down from within Windows, don't turn off the PSU from the switch on the back, and then turn it back on with the case power button, does it still do this?
