I just installed speccy (1.30.730) as a new user. All the data looks reasonable excepting the +12V bus reports about 9.8V. I installed it on a second PC and the 12V bus also reports about 9.8V. Since the PCs otherwise work fine I suspect a data gathering or presentation issue. Both are white boxes, one an MSI CD55 MB and the other an EVGA E650, both of 2009 vintage.
have you checked for BIOS upgrades to that MSI motherboard?
maybe the E650 PSU is showing its age!
All MSI updates have been applied. Consider that two different power supplies on two different mother boards, both working well, have an identical error circumstance with the +12V rail. Possible, but. FWIW one PSU was replaced about 2 years ago. Now if either PC had demonstrated any problem at all, but neither has.
a multimeter would confirm that.
but none the less, your post would be read by the Dev team and looked into.
