Price Per the Watt:
Power Supply XFX XXX Edition 650W at $119.99 = $0.19/Watt (02-2010)
It is becoming increasingly difficult to rate high end power supplies by performance alone probably due to the fact that what you find under the hood is produced by the same small group of printed circuit board manufacturers. The power supply market is very competitive and if performance levels are all very similar then price and/or a unique appearance may very well be the deciding factor when it comes to choosing a power supply for the next build or upgrade.
XFX power supplies certainly have a unique appearance with their industrial themed looks and lime green cooling fan and modular cable connectors, but how do they perform? The XFX XXX Edition 650W performed very well and gave good quality, well regulated DC across all the rails up to full load. What did let the power supply down was its failure to meet the required levels of efficiency for its claimed 80 Plus Bronze certification following the OCC power supply testing methodology and the fact that isn't listed on the 80 Plus Org website at the time of writing this review.
The XFX XXX Edition 650W power supply is certainly worthy of consideration for use in any high gaming system and will easily handle any single high-end graphics card gaming rig with plenty of room to overclock. There are a total of four PCI-E connectors available on this power supply so crossfire or SLI is definitely an option but keep an eye on power requirements especially with the more power hungry Nvidia offerings. The XFX XXX Edition 650W power supply performed very well and was only let down by its failure to meet the requirements of its claimed 80 Plus Bronze certification following the OCC power supply testing methodology. The efficiency levels are still pretty good and I have no hesitation in awarding the XFX XXX Edition 650W power supply a OCC Silver award.
