(Random shut offs) BIOS reading conflicting with DMM on +12v rail (11.3/12.08)

Pc has been event 41 shutting off for a while, replaced my GPU and PSU because of it, here are my current specs:
Warning: Spoiler! (Click to show)
I7 920

Asus rampage ii gene (cg5290)

CM g750m (3 months old)

Msi 280x 3g (6 months old, bought used)

3x4gb patriot g series 1600

Seagate 1tb 7200 sata

CM hyper 212 evo

Basically I noticed a low +12v rail in my BIOS hardware monitor (jumping between 11.1-11.4), especially after a shut off. However on my DMM, I probed the +12v on the molex,pcie,and every other power cord that has that rail including the motherboard ones and they all read 12.08v stable at the same time the BIOS was showing the 11.1-11.4v readings.

Does this mean my 6 year old motherboard is dying? Or could it be the 3 month old PSU calling it quits? Alternatively the used GPU I have could also be a culprit.

Looking forward to hearing your responses

Ps: memtest, sfc /scannow, chkdsk (all passed); temperatures and GPU/CPU usage % all normal.

Voltage readings using the BIOS or software programs?

I'll try giving my motherboard cables some slack, one of them is really tight, maybe causing some resistance.
