I own the ATX-GES version of the FSP unit linked to by BentValve. It is Balls Strong and CLEAN.
You will need the AMD (ATX-GES) version instead of the Xeon (EPS+12v I believe) version in the link if you don't want to use an adapter. The pin-out for the Xeon IS different than for the AMD.
FSP makes both versions and likely you can order the AMD version on the same site.
FSP also makes the FSP-460, which I also own, and run on another of my setups. Both of FSP units are AMD version. For the NF7-S v2.0 setup, I switched the pins to a twenty pin setup.
