While I have been away from custom building for a while, I went on a build of 2 systems in a row. Based on my research and the components of the system I wanted installed I went with the FSP Epsilon 600W in both systems.http://www.driverheaven.net/reviews.php?reviewid=692
The PSU is well built, the cables are well insulated (even with a black mesh to avoid snags on the case) and it has been working well for me in the two systems i built. One of the two systems is a file server and workstation combo with a lot of components (5x500G hard drives, 1 cd rom, HD Radeon 4800 1GB memory, power to 2-eSata drives). The PSU also provides independent poewr to the graphics card.
With all of the above connected to the PSU, I still have a couple of extra power connectors remaining out of the FSP. I like it!
Good luck with your build.
