Hi, guys, first time poster here and I'm looking for some help and guidance.

I have a GTX 660Ti Twin Frozr Power Edition which according to the manual requires a minimum 500 watts with 38A on the 12v rail and two 6 - pin PCI Express connectors. My current psu cannot supply the ampage so I'm looking to invest in a new one as part of a total upgrade of my pc. I'm planning to upgrade to a Haswell i5 system eventually so I want to get the psu choice right before I proceed.

I would really be grateful if anyone could give me a few pointers or suggestions.

Many thanks
