Benchmark Setup

Since my typical benchmark system resides in a MicroFly micro-ATX case, I'll be using my workstation to test the Seventeam ST-850P-AF. The workstation features three Radeon HD4850-class video cards in CrossFireX, as well as a quad-core Intel CPU.

Component Part
Case Thermaltake M9
Motherboard ASUS P5E64 WS Professional
CPU Intel Core2 Quad Q6600 @ 2.4GHz
RAM 2GB Patriot DDR3-1666
Hard Drives 2x Western Digital 36GB Raptors
2x Seagate 160GB SATA2
2x Maxtor 250GB SATA2
1x Hitachi DeskStar 7K1000 1TB
Video Cards Sapphire Radeon HD4850
Sapphire Radeon HD4850 Toxic
Palit Radeon HD4850
Sound Creative SoundBlaster Audigy
Misc. HighPoint RocketRAID 3120
Operating Systems Windows Vista Business 32-bit / Gentoo Linux 2008.0 64-bit

Of course, my hope is that I have enough hardware to properly stress-test the ST-850P-AF.


As with most power supplies, installation was quick and easy. After securing the power supply to the case, I connected the mother board connections.

Since the unit isn't modular, I was stuck with all the cables that came with it. That means I actually have to find somewhere to hide the unused cables.

After it looked satisfactory, I plugged the ST-850P-AF to the wall's AC outlet and switch the power supply to the ON position. The computer came to life... silently.
