Bad voltage readings from Antec SmartPower350

I just bought an Antec SmartPower 305W in like new condition from someone on the forum. I received it today and it looks in great shape. I just installed it and am a little concerned with the voltage readings i'm getting. The new supply has the positive readings much closer to accurate than the old supply, but the negative readings are much further off than before. I have a mobile 2400 at 2.2ghz and these are the voltage readings under no load: 3.3@3.26, +5@4.89, -5@-6, +12@12.04, -12@-12.86, +5VSB@5.46. Should I be concerned?
 
Modern motherboards don't use the negative voltages and if I recall correctly, the revised ATX power-supply standard doesn't even include either of the negative voltages anymore. So I would disregard that, and if you want accurate voltage readings, also use a digital multimeter and not BIOS or software readings. 🙂 Hope that helps ease your mind 🙂
