I have 2 machines
One an ASUS b150m with a Corsair rm550 psu and a
ASUS z270-a with Corsair hx1200i psu
The hx1200i was RMA’d after going ‘bang’ after 2 yrs
Now the new hx1200i won’t post the z270-a. However the Corsair Rm550 PSU will post that mobo into Win10 just fine.But the hx1200i itself seems ok because it will post the b150-m just fine.
So I seem to have proved both z270-a and hx1200i work with components but not together as they did before.
I’ve tried everything I can think:
Stripped z270-A down to cpu+Ram
Reset cmos
Booted it with another psu ok
Reseated all components.
I know the ram is ok.
Plugged the hx1200i into another pc & booted to bios to check the voltage rails are stable. 12,3,5 & cpu voltage.
Tried different modular cables for PSU
Why will one psu post the board but the other won’t but the other posts another pc.
When trying to post with the hx1200i the green led power light is on when I switch the psu on. On start button (on mobo) the cpu fan spins but no beep or post.
I’m stuck and going in circles now. Any suggestions? Thinking of getting a psu tester but as I said it posted my other pc (B150-m) fine and was stable for 24hrs. Voltage in bios looked fine
I’m leaning towards a weird mobo fault (a bit in despair) because my Corsair 550 boots that machine fine.
any suggestions r appreciated. Thanks.
