The Xigmatek NRP-PC402 power supply isn't going to appeal to the heavy gamer or overclocker, mainly due to the 400W rating, single 6-pin PCI-E connector, which severely limits the range of graphics card that can be used on this power supply, and the fact that some exhaust air is introduced back into the case. I am not a big fan of dual 4 pin molex to 6-pin PCI-E adapters used to supply power to a video card when 6 pin PCIe connections are not included as part of the cabling, even with that said I have no doubt it could power a single 8000 or 9000 series graphics card in a basic gaming system without any problems. I would have to class the Xigmatek NRP-PC402 400W power supply in the entry level class, but don't take that the wrong way as it certainly performed far in excess of any generic unit. As such, it may be better to look at this power supply as a computer enthusiast's entry level unit. All in all it's not a bad power supply, at a fair price, that would go nicely with a low end gaming or folding rig running a single 9600, an office/internet PC, or perhaps a Home Theatre/Media Centre PC. If you are in the market for a 400W power supply, then it's certainly worth your consideration. The DC voltage load regulation is excellent, efficiency still at basic 80 Plus levels, and noise/ripple, although a little higher than I would like to see, still not high enough to cause problems.
