I really can't tell you, a few things you should ask before you buy though.
Get the store to hook one up for you and use motherboard monitor 5 to check out the rails, if they are 5% over or under where they should be or are bouncing around like crazy you shouldn't bother with such a power supply.
Also, just pick it up. Any solid power supply will have good weight to it.
