Testing and Conclusion

Please click on thumbnails to get bigger pictures

Installation of the PSU was fairly straightforward. Simply place the PSU into the case and attach it using the standard four screws that are included. Finally, plug in all the cables you need and you’re ready to go. The cables had plenty of length to accommodate my case, which previously reviewed supplies had trouble reaching.

Testing

Testing was done by measuring the voltages at the connectors with a multimeter. Idle voltages were taken running Windows and full loads were taken while running 3dmark2005. Results of similar tests on a previously reviewed FSP Power Mods 750W PSU and the Coolmax CU700 700W PSU are included for comparison.

Setup:
AMD 64+ AM2 5500+
ECS GeForce 6100SM Motherboard
2 GB SuperTalent DDR2 RAM
GeForce 9800GT video card
Western Digital 250 GB 7200 rpm harddrive
Maxtor 200GB rpm hard drive
Hitachi 80GB SATA harddrive
LG DVD burner

3.3V testing

The 3.3v rail performance was very stable, as with most PSUs on the market.

5V testing

The 5V rail also has solid performance. Very little voltage drop and minimal voltage fluctuations were seen.

12V testing

Similar impressive results for the 12V rail were found. A little higher nominal voltage but well within the ATX specification.

As you can see, the NZXT Performance Power PP800W PSU delivers solid performance that did not vary greatly under loaded conditions. Very solid performance that should be great for any build. The noise performance is also admirable, despite having two fans. Perhaps this allows them to be run slower and thus more quiet, because I could barely hear the supply over the noise of the other fans in the case.

Conclusion:
As with most other NZXT products we’ve been lucky enough to review, NZXT’s Power Performance PP800 800W PSU delivers stable performance in a great-looking package. The design and top-notch build quality prove that NZXT knows how to make power supplies. While it is a little low on the extra features, the supply delivers “performance without sacrifice”, as NZXT claims. Check this versatile supply out for your next computer build.
