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.
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!
I just did a very similar build with the uATX Rampage II board, except I put it in a Thermaltake lan box with two WD Black 640s in raid 0. I think you will be happy with your mb choice.
I put a Corsair 550 in mine, very happy with it. Good quality power supply ..... Note, mine is a business only machine that I wanted to be able to lug around on occasion, so power for graphics was not an issue, but the Corsair seems like a good product so far.
If you are thinking of adding a second video card later, you want a bigger psu. Something like 750w corsair. If you're only going to use the single card, the corsair 550w or antec EA 500w are nice choices.
Hi can I ask Cockenbeer if u have made this machine yet because I'm thinking of doing a similar thing my specs so far are,
Intel Core i7 920
Asus Rampage II GENE microATX motherboard
6Gb of Corsair RAM I havn't fully decided on which yet,
A western digital Hard drive not fully decided on size,
A thermaltake Lanbox.
Obviously I am going to put fans and cooling in it and a drive, but what I am really concerned about is cooling. What clearance from the the top of your PCU to your processor do you have? Or is your PCU not above your processor. I have a mere 10cm to play with. And I think cooling is gonna be a major issue how did yours run? Did it melt???
