Testing power supplies is tricky without proper equipment, which we unfortunately couldn’t locate at the time of testing. But we did our best to find the best scenario to test stability and durability of OCZ’s GameXStream power supply. Our testbed consisted of Intel Pentium 840EE (operating at stock speed), 2x512MB Corsair 5400UL DDR2 memory, 1x Seagate SATA Drive at 7,200 RPM and 2x 7800GT SLI graphics adapters. The rest of the system was stocked with a standard DVD-RW drive, 4x 80mm case fans and a stock heatsink.

The impressive results we achieved with this power supply will bind to make every enthusiast delightful. From supposed 3.3v, 5.0v, and 12v rails, we recorded a discrepancy of only -0.3 percent (-) to 3.29v, 1.2 percent (+) to 5.06v, and 0.58 percent (+) to 12.07v at idle stages. The load conditions were just as extraordinary at 3.32v, 5.09v, and 12.10v ranges.

All in all, the performance of the power supply is topnotch, as our results proved. Since our system (read: CPU) was clocked at 100 percent usage, and we were running loops of benchmarks to strain the system as much as possible, we made sure to check noise levels as well as durability throughout our testing procedure.

As we pointed out earlier, our testing methodology is lacking in depth. However, straining the system for 48 hours under consistent stress with continuous loops should prove to be a viable measure of stability. We are glad to report GameXStream was an exceptionally stable unit throughout our stress testing. The system ran smoothly without hiccups in the 48 hours we tested the unit.
