i recently bought an antec smart power 500 watt supply and i was wondering if the 12v line should read at over 12.6 in bios. should i return this? even on my cheapo psu the 12v line was max 12.3 and all the other lines are within .1 of the rated. should i be concerned with this? this is my first antec power supply and i bought it because ive heard a lot of great things about antec.
