My guess is you're still using the older 20 pin style connector on your mobo? (perhaps post what mobo your usuing) If so look for something with a 20 pin or 20 + 4 pin main connector. I've used this one for several builds and had no problems:

It was cheap (price) but well built. If you don't care about $ then I would go for a bigger name brand like Antec. My preference in that regards is Silverstone, OCZ, and PC Power and Cooling. Not a big Antec fan but that's just me.
