The majority of the NeoPower Blue’s 650 Watts of power is delivered through three individual +12V rails, which deliver a substantial 19 Amps each, with the +3.3V and +5V rails able to pump out 24 Amps each. Plenty of grunt for a decent gaming system, and then some. Antec claim this PSU can run at its peak load of 650W continuously, all day every day, which is quite a claim of reliability and backed up by its 5-year warranty – so go nuts with it.

Power Spec Sheet

When testing the PSU under load, we had our test bench (Intel E6600, 2 x GeForce 8800GTS’s in SLI) running 3DMark06 and the difference between idle and on-load voltages was negligible, around 0.01V to 0.02V difference across the board. The voltages were very well within tolerances when on idle, coming in at:

• +12V1 @ 12.11V
• +12V2 @ 12.07V
• +12V3 @ 12.08V
• +5V @ 5.01V
• +3.3V @ 3.34V

And again there was only the most minor variation in the voltages when under load. A good sign of a quality power supply unit.
