OCZ's GameXStream 700W
Home court advantage

We've been using OCZ's GameXStream 700W PSUs in our test rigs for more than a year now. The Benchmarking Sweatshop is home court for this model, and since we've been using them for so long, we can tell you that they've been very reliable with a wide range of different system configurations. The GameXStream isn't necessarily any more reliable than the other PSUs in this round-up; we just haven't been playing with the rest of the field for nearly as long.

The GameXStream is relatively subdued on the surface. You get active power factor correction and SLI certification, but there's no 80 Plus badge or fancy modular cables. The warranty only lasts three years, so OCZ isn't breaking any new ground there. What the GameXStream does offer is 700W of output capacity—quite a lot given its affordable $115 street price.

OCZ hasn't cut corners just to kick out a cheap, high-wattage PSU, though. The GameXStream comes wrapped in black with a 120mm fan in charge of keeping things cool. There's also an LED tucked away that bathes the unit's internals in a blue glow when it's powered on.

All the cables are sheathed, too, and there's plenty of length to play with.

DC voltages are nice and consistent across all three loads. The 3.3V line is particularly accurate, but all lines are within about 1% of their targets.

What's particularly impressive about the GameXStream's voltages is how little AC content seeps into the lines. Over our 100-second test interval, ripple content averages rarely reach double digits in millivolts.

Efficiency is reasonably good, too, although it does drop noticeably when we crank the load up to 100%. This might explain the lack of 80 Plus certification.
