Publication 25823, page 3. Amperage on the 12V must meet or exceed 16.5A + 13A combined CPU and I/O, +3.3V must have a minimum 27A, +5V must have a minimum 29A. http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/25823.pdf Our old dual MP2000 was powered by a PC Power & Cooling 510XE. Rated for 640W peak, 510W at 50C. +5V 40A, +3.3V 30A, +12V 34A/38A Peak. Standard ATX layout. http://www.pcpowerandcooling.com/products/power_supplies/maxperformance/turbocools/index_hp_atx.htm As far as Chenbro, avoid at all costs. We had nothing but trouble with them. The backplane connections are non-standard (male to female,) and the backplanes frequently lost entire channels due to shoddy quality and failing to follow SCSI specifications. Heat was a constant problem due to a flawed layout, and the fans were pretty much worthless. I wouldn't take another one if someone paid me. -Ketrien I.
