Psu is msi mag a650bn,
I5 13400f
16*2 crucial pro DDR5
Crucial p3 plus 1tb
What could be causing the issue here?
Ive reseated the cpu, checked and found 0 bent pins, reseated the ram and all other power cables properly.

Dram and cpu, they tend to come on when powering up iirc

It’s been a while since I’ve had to look at some of this

The yellow lights tell nothing. Red light means cpu

smoky moth
#

Is your cpu new?

tired palm
#

It is new yeah

Is it because the psu keeps turning off
If yes then why does it keep turning on and off

Well so, what is the power draw vs the power supply output

#

Could be the power supply just doesn’t have enough power

#

Well it is a 650w power supply.. on a 13400f and no gpu..

If it’s a modular PSU check the CPU cable is used and not PCIE for the motherboard

Can you hear anything from the psu when the lights switch off?
