New PSU worked for a few days and then stopped

[Steveh_monkey]

Two days ago I upgraded my graphics card to a AMD RX 6600 XT. My old PSU was 10 years old so I decided it was probably time to upgrade that as well. Install went fine, everything's working great for a few days, and then today I try to turn on the PC and nothing. Instead when I try to turn in on I hear the PSU make a clicking sound but nothing happens. It made the same clicking sound when it was working correctly, as far as I know it's normal for when a PSU turns on.

My first thought is this is a faulty PSU as from what I know PSUs normally fail quite quickly if they fail at all, and everything else was working fine. I've rechecked some of the connections in case they weren't secure when I installed but everything seems fine. Are there any others things I should try or test before removing and sending back?

The Power supply is a BeQuiet Straight Power 11 650W. My system is Ryzen 3600, RX 6600XT, 16GB of ram so I think the power supply has plenty of power to cover those components.

Thanks for your help!

Do you still have the old PSU? If so can you try and plug that up to the motherboard and see if it powers the board, then you will no that the other newer one is dead. You are just checking power so no need to rip everything out to do this.

Just a quick question, but the wires you are using are all from the new psu correct? You didn't reuse any of the older wiring did you?
