So, to keep it simple, I found a very nice deal on a GTX 470 Twin Frozr II, and wanted to get it, but I'm wondering if this PSU will be able to handle it, this will be a full build, and this is at the end of my budget, so please don't suggest and i3's, even with H61 mobo's.Another thing, I could also get the XFX 550W Core edition PSU, but this is cheaper, and have seen someone run a GTX 480 on it on a different forum.

PSU Specs (Bottom) :



Parts list :

Phenom II x4 955
Asus M5A78L-M LE AM3+
GTX 470 Twin Frozr II
4 GB 1600Mhz 1.5V DDR3 RAM (2X2GB)
Sony 24X DVD Writer
Thermaltake V3 Black Edition with extra fans
Windows 7 Home Premium 64bit

~Thanks in advance for any help given, I'm looking to order this PC in the next few days.

Worst case scenario you'd have to use 2 different rails. Ie take 1 6 pin from 1 PCI-E power cable and plug in, and instead of using the 2nd connector on the same string, use another string. Each PCI-E should connect to a different 12v rail. Thereby allowing you 36A for your 470. That would give you 432W for the GPU.

Because I'm pretty sure 18Ax12V=216W isn't going to be enough juice for a 470.

Unless he uses molex adapters there's no choice, both PCIE connectors are on the same string, will still be getting power from 2 rails ( the slot is on a different rail )

Hmm, that's odd, I think I may just get the 600W ModXStream Modular Pro instead.
