Tagan BZ 900W

Performance:

The test-bed used for stressing the Tagan BZ 900W was a Tyan Tempest i5400XT motherboard, 4GB (8 x 512MB) of Kingston DDR2-533 memory, dual Intel Quad-Core Xeon E5320 processors, Western Digital 160GB SATA 2.0 16MB cache HDD, Lite-On SATA DVD-RW, and an ATI Radeon HD 2900XT 512MB graphics card. This hardware was housed inside a Cooler Master Cosmos S chassis. On the software side, we were running Ubuntu 7.10 x86_64.

When installing this power supply we had run into no problems and the modular cable installation was easy. A threaded screw cap keeps each of these power cables securely connected and each cable was of adequate length even for the power supply being mounted in the bottom of the chassis and an Extended ATX (EATX) motherboard being used. The Tyan Tempest i5400XT requires a 24-pin EPS connector, 4-pin ATX connector, 8-pin EPS connector, and a 4-pin molex connector.

Once installing this power supply we were surprised at just how quiet it operated. The Tagan BZ 900W is among the quietest power supplies we have tested. Using a calibrated digital multimeter, we had monitored its voltages when the system was idling for 30 minutes within the GNOME desktop and then under load by running Enemy Territory: Quake Wars for the same amount of time. The voltages were recorded when the power supply was set to its "TURBO" mode.
