If you do need to buy a new power supply, we’d recommend these. We’d suggest swapping out the power cable you’re using, and possibly trying a different wall socket before going down that road, though. If not, then you might need a new power supply. If you’re still getting absolutely nothing when you press the power button, look to see if your motherboard has any idle indicator lights to confirm that the motherboard is definitely receiving power.

For more information on that, check out our comprehensive PC build guide. It’s also worth checking that your motherboard and CPU power cables are plugged in correctly. Is the power cable plugged into the wall and the other end into your power supply? Are the wall socket and PSU switched on? Double-check each end to make sure everything is connected properly. Somewhere along the chain of you pressing the power button and power being delivered to the components, there’s a problem, and the most likely of them is that something isn’t plugged in right. However, the fact that nothing happens is a clue in and of itself. This might be the most demoralizing of all PC fixing problems, because you don’t have much to go on when your PC won’t turn on.
