High 12v Rail

Wiggins · 1 Sep 2007 at 12:26

I'm hoping someone can put my mind at rest.

I bought a 580w Hiper the other day and after installing it I booted, looked in the bios and the 12v was @ 12.28v :confused:

This was with everything at stock and the weight of the hardware power balanced over the psu.

When I overclocked the cpu it jumped to 12.35v. Now I know that there is 10% headroom you have to give on psu's but isnt this a little too high?

When I stress the system on Orthos, the vcore hits 1.31v which is cool but the 12v only drops to 12.29v.

Your advice would be greatly appreciated.

Many Thanks

It's a 5% variance that's allowed, 12.35v is well within that.

Fantastic......

Many Thanks for your help

As Raikiri says that is well within tolerance levels but you should also remember that any reading not done with a multimeter might not be entirely accurate.

check hiper's website they say the purposley keep the rails a littler higher than thier actual rating. its a good thing since when the rails are loaded up they drop a tiny bit but still end up above 12v.

Thanks guys

I did check voltages in bios, everest and speedfan and they all reported the same voltages.

Nice to have a PSU that doesnt drop to 11.94v when under load

Again, many thanks.
