Results and Conclusion
First, we have the idle results with the system booted into Windows and sitting idle on the desktop. The XFX already looks better then the Cooler Master as all the voltage rails are above where they should be. The Cooler Master is very close on all rails, and just a hair under on its 12V rail for the main 24pin connector.
With the system running full tilt the XFX is still doing rather well, holding above the required voltages on all rails. The Cooler Master, however, dropped below on all but one 12V rail. It also is just sitting ever so slightly above on the 5V rail, and right on the 3.3V rail.
Now let’s take a look at the power consumption results. At idle the XFX unit was better running at 224w as opposed to Cooler Master running at 229w. Under load, however, Cooler Master won out running at 963w -- 30w lower than the XFX.
We did see the XFX peak at 1,008 watts at the wall on our Kill-a-watt meter. We did not observe the same peak when testing the Cooler Master. So, a pair of ATI HD5970’s in CrossfireX configuration may be a bit much for the XFX 850w Black Edition, but it should handle any triple SLI or Crossfire setup with ease.
Conclusion
XFX’s first step into the power supply ring was a solid one, and if this is the performance we can expect to see from their future offerings then we can expect a nice line up from XFX.
The only thing that some may have an issue with is the color scheme that XFX has chosen for the 850w Black Edition. The day glow green may not fit with most users' tastes. Other than that the unit was solid, quiet, and handled everything we could throw at it.
The XFX 850w Black Edition can be found for $199.99 plus shipping before a $30 rebate. At this price point it is comparable to other units in its power range and build quality.
Legit Bottom Line: XFX has a solid performing power supply in its lineup. If it fits your style then give the XFX 850w Black Edition a look.
