PC not posting after PSU & GPU replacement

[Pixelfie]

So I just upgraded my PSU and GPU. Now my PC gives a black screen with a red light on CPU and DRAM. All fans are spinning full speed, except for my exhaust fan which is not spinning at all. I've made sure all cables are connected properly and they are.

 

 

i5-10400F

MSI Gaming X RX 5500 XT 8gb

2x8gb HyperX Fury RGB 3200 CL16

ASRock B460M Pro4 (P1.50)

Corsair RM650x 2018

What were the old PSU and GPU? Did you make sure the new parts are not defective?

Old PSU was a System Power 9, old GPU was a 4gb Sapphire Pulse 5500 XT (was sent for RMA because it made a weird sound, was offered a replacement). GPU was fully tested by the seller, not sure about the PSU

 

Will try a CMOS clear and RAM reseat

Just did a CMOS clear and RAM reseat, still the same issue. Rear fan is spinning now though

I know you don’t have integrated graphics but have you tried booting without the GPU to see if the lights go away? I don’t really see the relation between the parts swapped and your issue but it clearly exists

Damn, I'm so dumb. I somehow forgot to plugin the 8 pin CPU connector into the PSU itself xD
