Firstly thanks in advance for any help regarding this matter.

I recently purchased a few pieces from OC to complete a new PC Build.

Corsair Vengeance LPX 32GB (2x16GB) DDR4 PC4-25600C18 3600MHz Dual Channel Kit (CMK32GX4M2D3600C18)£54.161£54.16
Asus Prime B660M-A WIFI D4 - Intel B660 DDR4 Micro ATX Motherboard£108.331£108.33
Corsair RMe Series RM750e Fully Modular Low-Noise ATX Power Supply v2 (CP-9020262-UK)£74.991£74.99
AeroCool Trinity V2 Mini Tower PC Case - Black£24.991£24.99
WD Blue SN580 1TB SSD NVME M.2 2280 PCIe Gen4 Solid State Drive£48.29


In addition to these I have a cpu and gpu I purchased from a different supply due to stock issues before Christmas.

The PC has worked flawlessly over the past month or so without a single issue.

Now the PC will not turn on at all, no lights, no fans spinning, no beeps.

The PC did not die whilst is was being used was just off then on.

I have tried the following.

1. Different PSU - still nothing
2. Different Case - still nothing

Any ideas what else to test ? I’m confident with a multimeter if there are places I can check before speaking with OC technical tomorrow.

I want to at the very least be able to pin point the issue so that I’m not wasting anyone’s time with a return if it is something I can fix myself.

The pc has only ever been plugged in with a surge protector so I’m baffled as where to check.

Again thanks for any helping with this.
 
You say you tried a different PSU, but did you use the same power cable? (thinking fuse gone)

Have you tried plugging straight into wall socket and not the suge protector?

Sorry i can't be much more help, but am sure some of the more knowledgeable people will be along soon.
 
Yeah I tried new lead, the PSU was pulled from a working machine also.

I’ve also been through the fault finding sticky here on the forums also.

Appreciate your time helping sir
 
Have you tried jump starting the original PSU to see if it's alive?
If the PSU is good and nothing is happening I'd be inclined to say it was the board as it would still all light up without a CPU or ram..
 
When you tried a different psu
Did you reuse the original modular cables?
Or the ones that came with the different psu?
Assuming that was also modular

Could try taking the 2 pin connector from the
Power on/off button off
And see if bridging the pins with a screwdriver works
Just in case the pc case on/off button is wonky

If you're confident with a multi meter
You should be able to test the psu?
Though like the paper clip test
That may only show if its totally dead/not dead
But not whether it's fully functional under load

Don't think a board in that price range will have dedicated
Voltage read out spots
Usually find those on more expensive boards
