Question PSU keeps blowing 5A plug fuses ?

[bill001g]

It all likely doesn't matter. If it is not something simple like power cable itself is defective or maybe the surge protector this can't be fixed. Likely try a different power cable rated at the same amp. If it blows that one also then you pretty much know it is the power supply. Running with it directly plugged into the wall would eliminate the surge protector.

There is not going to be anyway to fix the power supply and if he had those skills he would not be here asking.

It is highly unlikely it is some issue with the computer. Almost all modern power supplies have protection on the DC side of the power supply. If say the video card tries to pull too much power it will just trip off the protection or on some very cheap models it blows fuses internally. This protection circuitry prevent the issue from getting to the AC side. If these circuits have failed or there is a issue in the AC side of the power supply it is time to buy a new power supply.

I can confirm that it was the 5A fuse in the PSU's plug that blown. And I've always used a surge protector with it, even when it blew the replacement fuse.

When I first noticed that my PC wasn't turning on, my monitors (which were both plugged into the surge protector) still powered on and went into standby, if that helps.

Truth be told upon getting in and looking at it, I don't know. I think I'm just going to RMA it and buy a new PSU - then pray that it's not an issue with my rig that'll just ah heck up PSUs.

Double check the surge protector it might have also a blown fuse on a good surge protector most plugs are wired as just 1 on cheap surge there wired as a group of 2

I don't have much to add to this. I bought and fitted a new PSU and it's been working swimmingly, and thankfully none of my components have fried.

I've had no problems the surge protector, but I'll probably replace it within the week just to be sure.

I also picked up a PSU bridger but I didn't test the old PSU as I can't trust it - even if it turned on in the test without a hitch, there's no way I could guarantee my rig's safety if I plugged it back in.

Bit of a non-climatic ending I'm afraid. If I RMA the old PSU and find out what the fault was, I'll make a note of it here. Cheers x

you can always test the psu with a psu tester like this

if all the lights minus the -5v turn on then the psu is fine
