Seems nice (im considering getting one) and its been very well reviewed. Here's the technical lowdown if you're interested
Voltage Range
115 Volt Nominal: 103V Minimum, 132V Maximum
230 Volt Nominal: 206V Minimum, 264V Maximum
Maximum Steady State Current
115VAC (RMS): 10A
230VAC (RMS): 5A
VAC = Volts Alternating Current
RMS = Root Mean Square
Maximum Cold Start Inrush Current @ 25 degrees Celsiis
115 VAC: 50 A
230 VAC: 100A
Operating Frequency
50Hz-60Hz
Power Efficiency
A maximum of 70% at full load, 115230 VAC 60Hz/50Hz
Outputs
Probably the most important part of any power supply.
+5 Volts
Maximum Load: 30 A
Minimum Load: 0.3 A
Regulation: 5%
Ripple & Noise (mv): 50
+12 Volts
Maximum Load: 34 A
Minimum Load: 2 A
Regulation: 5%
Ripple & Noise (mv): 120
+3.3 Volts
Maximum Load: 28 A
Minimum Load: 0.5 A
Regulation: 5%
Ripple & Noise (mv): 50
-5 Volts
Maximum Load: 0.3 A
Minimum Load: 0 A
Regulation: 10%
Ripple & Noise (mv): 50
-12 Volts
Maximum Load: 0.3 A
Minimum Load: 0 A
Regulation: 10%
Ripple & Noise (mv): 120
+5VSB Volts
Maximum Load: 2 A
Minimum Load: 0 A
Regulation: 5%
Ripple & Noise (mv): 50
Note that the total continuous maximum output wattage is 500Watts for all the lines, however it is 480Watts for the +5V, +12V and +3.3V.
Overvoltage Protection
Overvoltage protects the power supply and your components from deep frying in the even of a spike or a short. This feature kicks in if the +5V rail reaches 6.1V or the +12V rail reaches 14.3 or the +3.3V rail reaches 4.1 V.
Operating Environment
Ambient operation temperature: 0 to +40
Ambient operation relative humidity: 20% to 90%
Ambient storage temperature: -20 to +85
Ambient storage relative humidity: 10% to 95%
