Testurteil: "Bronze"
Test: Einzeltest: Xigmatek NRP-PC402 400W
Zitat: Pros: + Very good DC Load Regulation
+ High efficiency.
+ Active power factor correction.
+ Price.
+ Quiet.
Cons: - Excessive noise/ripple on DC rails.
- Single PCIE 6pin connector.
- 80 Plus Bronze not quite met.
- Incorrect feature listing on packaging of PCIE (6/8 pin connector when it´s 6pin only)
I could only find this power supply available in Europe and Australia with no USA suppliers, but I´m sure this will change. Xigmatek are probably better known for its quality processor coolers that usually end up performing only marginally poorer than their much more expensive counterparts and this power supply follows in the same tradition. The performance of the Xigmatek NRP-PC402 was pretty good, but when the UK price tag of only £40.00 is taken into account, it´s certainly well worth your consideration. It easily maintained the rails at the required voltage up to its rated 400W loading and the efficiency was excellent (although, following the OCC testing methodology, it just fell short of the 80 Plus Bronze mark). The ripple/noise levels are a little disappointing, but won´t prove a problem when installed in a system with a good quality motherboard. 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. I think the Xigmatek NRP-PC402 still deserves an award based on its price/performance ratio and for that reason I think an OCC Bronze award is well deserved.
