3.28-volts to 3.26-volts = 0.02-volts Δ

Looking at the 12-volt rail we can see that the rail starts off at 12.3-volts and jiggles along to end 12.25-volts a Δ of 0.02

 Most computer supplies use a tolerance of 10% on their rail voltage before they will get the green light from the manufacturer we prefer to use a 5% option and it is clear that even using that number the the power supply past with flying color.

Conclusion

Our results show that the CoolerMaster Real Power Pro 1000 is truly a workhorse that can easily handle a dual core processor along with a dual GPU video card combined with a cooling system that consists of six thermal interface devices. This is the first power supply to date that we have tested that would allow use to combine a pair of HD3780X2 video cards since the power supply has dual eight pin plugs and more than enough 6-pin PCI-e connectors.

If you are in the market for a new power supply or just want a spare to have on hand, look no further than the CoolerMaster Real Power Pro 1000 watt power supply, you are not just making a purchase you are also making an investment!
