Testing:

Now let's see how this power supply holds up against other power supplies while idle and at load. I am going to compare the Real Power Pro 1250 with the Cooler Master Real Power Pro 750W PSU and the Sigma Shark 635W PSU to see how it holds up with the six rails versus the four rails of the Real Power Pro 750w and the two rails of the Sigma Shark 635W power supplies. Does having more rails make the difference in power and stability? Well we are about to find out.

To load the Real Power Pro 1250W PSU, I loaded it up with extra hard drives, 3 video cards, 2 optical drives, and extra fans. Then I ran Prime95, AVG Anti-Virus, a DVD movie, and looped 3DMark06 to stress the system as much as possible.

 

Testing Setup:
  • Processor: Intel Core 2 Duo E6700 @ 2.66GHz
  • Motherboard: XFX NForce 680i SLi
  • Memory: 2GB Patriot Extreme Performance PC2-9600
  • Memory: 2GB Patriot Extreme Performance PC2-9200
  • Video Card: Foxconn NVidia 8600GTS 256MB
  • Video Card 2: Power Color HD2600 Pro 512MB
  • Video Card 3: Gigabyte X700 128MB
  • Hard Drive: 1x Western Digital 80GB SATA
  • Hard Drive 2: 1x Seagate 750GB SATA 3.0
  • Hard Drive 3: 2x Western Digital 40GB IDE Drives
  • Optical Drive: Lite-On 8x DVD+/-RW Drive
  • Optical Drive 2: Samsung 16x DVD ROM
  • Fans: 4x Thermaltake 80mm Fans
  • Fan Controller: Vantec Nexus Multi Fan Controller
  • Operating System: Windows XP Professional w/SP2
 
Power Supplies Tested:
 
Testing Equipment:
  • Sperry Industrial 18 Range Digital Multimeter.

 

First up are the 3.3 voltages. Remember you want to be as close to the 3.3v as possible.

 

 

Now we have the 5.0 volts

 

 

And lastly for the 12 volt rails.

 

Even under stress, the Cooler Master Real Power Pro1250W held up quite well, never deviating from the specified voltages more than the negligible amount allowed in a power supply. Not once did I get any feeling that my hardware was underpowered while stressing it. Now I know I can add anything to my computer and no longer worry if I have enough power to push it to the max.
