Its when i have had a faulty mobo or psu there as always been some life, but ive only have one dead cpu and there was just nothing. but it could easily be the mobo too

its a tough 1 to narrow down without parts or tools to do checks.

Just had a look at CPU compatibility list and the Ryzen 7600 is supported from bios 0602, there is no bios 0602. :confused:

Hope the new board works out for you. Did you order the same one?

Tested with new mobo and same issue..

New mobo has LED indicators and getting nothing on them either so must be the psu then.
Just tried jump start on the psu with the paperclip and again nothing from the psu, no fan spinning or the slightest hum

if you have the right 2 cables and get nothing its dead.
for poo and giggles you have the switch on the psu to on right... i ones did that and it about an hour of messing till i noticed :cry:

at least the PSU will have warranty.

yeah I checked that a few times just to check! Amount of times I have made mistakes like that! It's just surprising that I was able to flashback the bios using that PSU yet I can't get anything from it at all!

PSU or CPU .

Are you testing outside the case ?

djc_2005 · 2025-01-12T17:03:07+0000

All tested outside the case and tested without the CPU present too which I would expect the PSU to fire up case fans etc when connected but still no dice

no if there is no CPU at all you get nothing, its not like ram where you get an error message on screen.

it would use standby voltage for flash back... but yer you would think dead is dead...
check all cables are seated right on the PSU side, and that EPS is in the right socket

Well this new mobo has led indicators to show CPU, ram, VGA or boot fault and none light up either. I would hope this would detect CPU if the CPU was at fault

it would. so yer psu.

did you boot board with just cpu and ram?
any AM5 board will support 7600x from day one bios so you can rule that out

get the psu RMA'ed
