PSU diagnosis confirmation

Hey, recently been looking into why my computer has been shutting down unexpectedly, no bsod, and fails to boot after.
Looked into hardware monitor and saw my voltage was exceedingly low on my -12v side.

Referring to said chart :

Supply [V] Tolerance Range (min. to max.) Ripple (p. to p. max.)
+5 VDC ±5% (±0.25 V) +4.75 V to +5.25 V 50 mV
−5 VDC ±10% (±0.50 V) –4.50 V to –5.50 V 50 mV
+12 VDC ±5% (±0.60 V) +11.40 V to +12.60 V 120 mV
−12 VDC ±10% (±1.2 V) –10.8 V to –13.2 V 120 mV
+3.3 VDC ±5% (±0.165 V) +3.135 V to +3.465 V 50 mV
+5 VSB ±5% (±0.25 V) +4.75 V to +5.25 V 50 mV

Seems like that is the problem, but I'm just making sure, because, seems too easy...

Check the voltages in the bios an report back !

Why the ****. Ask next time before buying. Xfx 550 W Pro core is better and cheaper 54$ @ncix !
