http://www.itwinkle.com/hp57posub.htmlNothing special about that Power Supply except for the PRICE!
It's just a regular ATX SMPS with a 575 Watt maximum rate wattage, and an 8-pin EPS +12 Volt power cable.
The HP part number is HP 405349-001
I just THOUGHT the above model was expensive,

[NOTE*
NOT to be confused with the 8-pin PCI Express power cable,
http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress8Yellow wires are 12 Volt wires. Black wires are Ground (Negative) wires.
The 8-pin EPS +12 Volt power cable has FOUR 12 Volt wires.
The 8-pin PCI Express power cable has THREE 12 Volt wires ]
I believe 4 SATA power cables,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheralPower Supply case dimensions are approximately
6 Inches Wide, 5.5 Inches Long, and 3.5 Inches in Height.
(152.40mm Wide, 139.70 Long, and 88.89mm in Height )
36 Amps combined for the two 12 Volt power rails.
(12V1 = 18 Amps, 12V2 = 18 Amps)
This is an example of a replacement SMPS,

I'm running one of these right now in a Dell Optiplex 745
Yes, even though the power cabling noted on the Tigerdirect ad is erroneous, it DOES have an 8-pin EPS +12 Volt power cable.
One 24-pin ATX main power cable
Four 4-pin Peripheral power cables
Six SATA power cables
One Small 4-pin Peripheral power cable. (Used for a Floppy Drive, or a Card Reader)
Two 12 Volt power rails. 12V1 = 23 Amps, 12V2 = 20 Amps
Combined = 43 Amps on the 12 Volt power rail.
Repair?
Due to the possible electrocution hazard, I don't post info on repair.
I will state;
The capacitors need to be PROPERLY discharged, before attempting to work on the unit.
The Radial Aluminum Electrolytic Capacitors are the weakest link.
For additional questions please post in a Comment.
