Installation

Installation of a PSU of this size is just about the easiest thing you can do in a PC. No problems, whatsoever.

Testing

For testing PSUs with a bit of a hefty wattage we like to put every piece of hardware we have together to mimic the most powerful of PCs that some of you will have. So we put together these two PCs:

Master PC
Intel Core 2 Duo E6600 @ 3.24ghz
Asus P5W-DH Deluxe
2 x X1950 PRO (Crossfire)
OCZ 2GB Special Ops PC6400 5-5-5-15 @ 850mhz

Slave PC
AMD Athlon X2 3800+
Asus M2N-E
eVGA 8800 Ultra
OCZ 2GB . PC6400 5-5-5-15

The GameXStream then powered not only the master PC, but it also fed both 6pin slots on the 8800 Ultra, about 4 HDDs and 6 120mm fans not including the CPU coolers; oh, and each PC had a molex powered PhysX card in too :).

Using Asus Probe and a multimeter for confirmation, we recorded the voltages of the rails over a 30 minute period with everything at idle and then loaded every component we could and repeated the result taking.

Results

As you can see from the results, this PSU is relatively stable when switching from idle to load but its rails are not very tight at all. with the 12v hitting 12.5v at one point! The other rails aren't too bad but the 5v rail is only 4.889 under load which isn't great.
