Resolved 2008 MacPro Power Supply Fail?

just want double check before order replacement power supply, symptoms don’t seem match others or service manual. may ocd, however.

2008 macpro not power up. no advanced warning, refused power 1 day. pulled video card , hard drives see if loading issue. smc has been reset.

power-on led above power button not light up. trickle power led (2) lights no led 8 (main power ok). when power button pressed, hear faint click power supply area , 1 few seconds later.

reading tons of info on line, mean short somewhere, bad cpu, or bad connection, failed power supply, or logic board. don’t see obvious short or extraneous metal laying around, , there little dust.


so, assuming i’ll end needing power supply, whats current opinion on buying power supply used ($100) vs new ($300). tips on outlets better others?
