My pcs power keeps blinking on and off everything connected blinks on and off . the PSU fan moves a little bit and the power stays on for a split second then turns off for about 2 seconds then blinks on again. This is even when I haven't pressed power button and it is connected to mains. Please help

Might be a bad PSU.

Disconnect everything in your computer. Take our your graphics card and RAM, and disconnect your CD Drives/ Harddrives. So just literally just leave the power connecter in the motherboard/ CPU part.

Now turn it on. If the symptoms are the same then it's probably a bad PSU. If the fans whine up, shut your computer off and connect everything one by one until you have the same symptoms.

What ever makes it not power on 100% then that'll be the faulty part. Try in another computer if you can just to make sure!

XFX, Seasonic and Corsair make the best PSUs. The PSU is the most important part of a build. A crap one is dangerous one. Return the one you have for being faulty, then buy a good one.
