To test the PP800, we first put the system at idle and used a hand-held multi-meter to ensure the accuracy of our onboard sensors. Then, a load situation consisting of Folding@Home SMP running on the CPU, ATITool 3D visualization running on the GPUs, the primary hard-drive defragmenting, and a CD being copied from the optical drive to the secondary drive was maintained on the system while the multi-meter was again used to ensure the accuracy of the readings. For insight into the ripple and stability of each line (3.3V, 5V, and 12V), we ran an OCCT stress test along with Everest Ultimate for real-time monitoring.

As is usually the case on power supplies, we find pretty good performance on the 3.3V and 5V lines. Though not rock solid, with ripples of 0.03 (0.88%) and 0.08 (1.56%) respectively, the numbers are not bad at all. Where we usually see companies drop the ball is at the 12V line. Not so with the PP800, where we find performance in the same range, with a ripple of 0.08 (0.66%). While I'm usually not one to advocate a multi-rail 12V design, it seems to have done NZXT well on the PP800. Continue on as we wrap up this review with some conclusions…
