Well
In fact I use a Powersafe 600w that cost me 5000 bucks. but then my gfx card wanted one. It came with all that you could ask for.
Sleeved cables,1x24 pin connector, 12v@ 22A ( Not much tolerance though I checked out), 8x12v connectors, 2x4pin mobo connectors, 2xSata connectors, 1x6 pin PCI-E connector......
The thing is tad heavy, comes with nickel plated xteriors(like mirror), 2 80 mmled fans(1 back, below).
Now the other option is the 500W SMPS from Powersafe that might fetch for 2600 bucks(Not sure though), but that comes for 12v @ 18 A ( I'd checked out).
See ya
