QTechnology's Quiet 460W is a server-class PSU with a PEG connector, somewhat strangely. It's not outwith the bounds of possibility to create that configuration though, with something like an Opteron mainboard with nForce4 Pro. Testing went well, although the supply ended up very hot on one side after heavy load testing, much like some other PSUs containing a single 120mm fan. Airflow just isn't optimal. Voltages were fine under load. The PEG connector can't supply more than an 8A current (~96W), which may or may not be a problem depending on the card you connect to it.
A solid PSU that was quiet and dished out the full 460W of output power without fuss or bother.
Recommended system: Mid-range to high-end desktop systems based around P4 (including high-speed Prescott), AMD Athlon Socket A and AMD Athlon 64 and Sempron on Socket 754 and Socket 939. Server systems due to SSI connector.

The fact I've got absolutely zero notes for the Thermaltake Pure Power-460 bar one on heat is a testament to its solidity. It passed the full-load 460W test with flying colours, the voltage rails at high loads were spookily spot on, it didn't make much noise due to a 120mm fan and efficiency was good. High-end systems are well catered for in terms of connectivity. It did get hot on one side at high load, as did many other 120mm-equipped units. Close to perfect.
