Hiper Type-M 780W
For testing this 780W power supply from Hiper Group we had installed it in a system made up of dual Intel Xeon E5320 Quad-Core processors, 4GB of FB-DIMM memory, Western Digital 160GB SATA 2.0 hard drive, and an ATI Radeon X1950PRO 256MB graphics card. The motherboard being used is the Tyan Tempest i5400XT. The power supply had installed fine into a NZXT Tempest and it had worked with this EPS12V system.
On the software side we were running Ubuntu 8.04. Idle testing had occurred as the system was idling within the GNOME desktop for 30 minutes while the load voltages had occurred after running Enemy Territory: Quake Wars for the same period. The voltages were recorded using a calibrated digital multimeter. Before sharing these results, we want to add that this power supply was quiet while in operation. This wasn't the quietest power supply we have used, but it's been among the quieter ones.
When testing the Hiper Type-M 780W its voltages were close to their theoretical ideals. There was a bit of fluctuation on the +12V rails, but not enough to cause great concern. The Type-M 780W was enough to handle our octal-core Intel Clovertown setup with eight sticks of FB-DIMM RAM and an X1950PRO graphics card, and there's still a bit of room left to expand. The Type-M 780W uses active PFC, has four +12V rails, ATX12V v2.2/EPS12V compliant, and is NVIDIA SLI Ready. In addition, it's among the quieter power supplies we have used. At this time the Hiper Type-M 780W can be found for about $130 USD, which isn't that bad of a deal, compared to the more expensive options from SilverStone and PC Power & Cooling / OCZ Technology.
