To test the Antec TruePower New TP-650 power supply we started with one instance of SiSoft Sandra's Burnin Wizard set for maximum processor utilization. We then ran a copy of Prime95 to make things work kust a bit hearderThe Load tester we use is adjustable from about 25 watt up to a maximum of 900 watts +-5%, so we adjusted it to as close to 620 watts as possible and then ran our testes.
Our first tests were done on the 3-volt rail and we watched as the voltage went to a high of 3.420 volts DC and then saw the lowest point which is 3.360 giving use a difference of 0.060 volts well within the specified 5% tolerances.
On the 5-volt rail we see a high reading of 5.174 not the 51.74 volts as it reads I forgot to take the 10X counter off. The minimum voltage was 5.118 volts thus giving us a total difference of 0.056 Volts, once again well within our limits.
The final test we ran was on the 12-volt rail and this one also measured the tightest on the rail voltage of any the ones we checked. Starting with a high or 12.02-volts and a low of 11.96-volts, giving us a difference of 0.04-volts which is a close to perfect as you can get.
