Solid PSU

white Reviewed By: TGuY on 2/9/2008
Rating + 5
Tech Level Tech Level: high - Ownership: 1 week to 1 month
This user purchased this item from Newegg
Pros: I bought this PSU, as I needed 6 SATA power connectors, and didn't want to use splitters. I also like supplies that use a 120mm fan, as they're quieter and can be upgraded to actually still move good air. The case I have this in, doesn't havea ny good rear ventilation, so upgrading the fan is the route I went. This was only necessary, as the stock one was meant to be quiet.
Cons: SATA power connectors are all the straight line type, not the flush mount. Not that it's really a "con", but would have been nice to have the other style.
Other Thoughts: I put this PSU into NORCO RPC-800 rack mount case, and needed long cables. The cables with this supply ended up being just right. They might be a bit long for any sort of small case.
