NZXT Performance Power 800W Power Supply Review

Installation & Use

I connected the PSU to my rig with an ASUS M3A32-MVP motherboard, Athlon X2 6000+, 8 GB of DDR2 RAM, three SATA hard drives, a Creative X-Fi gamer, and a Foxconn-made nVidia 8800 GTX.

Idle and load spot checks placed the 3.3V, 5V, and 12V rails at 3.33V/3.31V, 5.12V/5.12V, 12.01V/12.02V, respectively.

I used OCCT Perestroika, my favorite PSU testing program, to load up the system and monitor the voltages while under heavy load. For comparison, I’ve included the output graphs from the ThinkComputers review of the BFG ES 800W.

The 3.3V rail rippled more than the others-0.60%-but was quite stable throughout the test.

There is some light instability in the 5V rail, but only if we’re nitpicking. A ripple of 0.39% is next to nothing.

The 12V rail was very stable throughout the testing, rippling a mere 0.58%. There were a few spikes, but nothing more than negligible.

All rails overvolted by an amount well within acceptable limits.

As for the noise concern, I could tell a slight difference in the amount of noise coming from my computer. It, however, is not alarmingly loud, and is to be expected when adding another fan to a system.
