Seasonic X750's High 12v Rail

post #1 of 4
Thread Starter 
My Seasonic X750's 12v rail reads 12.288v in the bios and I know that this is "in spec", but it seems a bit high to me. I've had it for months and it runs fine, no coil whine, etc... but it kinda bugs me to see the 12v rail so high (the other rails are normal). I'm kinda tempted to just "upgrade" to something else, but I'm curous: for other people who own the psu, what do your 12v rails read? Is this that big of a deal? It's my first Seasonic psu and the Corsair's that I've tested on the system seemed to be .1v lower.

Don't use the BIOS readings as reference, grab a multimeter.

What's bad is for the voltage to jump around a lot, not be consistent. 12.288V, if true (grab a multimeter), is well in spec and not an issue.

If it makes you feel any better, your computer is probably not loading the power supply much in BIOS; it will drop some under load.

Like SimpleTech said, BIOS readings can be inaccurate. Using a multimeter to physically read the voltages will be much more accurate.
