I want to order this PC Power & Cooling - it has a 6pin GPU connector.. very confused! http://www.newegg.com/Product/Product.aspx?Item=N82E168... PC Power & Cooling S75QB 750W ATX12V / EPS12V SLI NVIDIA SLI Certified (Dual 8800 GTX and below) CrossFire Ready 80 PLUS Certified Active PFC Power Supply - Retail with: ASUS P5E LGA 775 Intel X38 ATX Intel Motherboard http://www.newegg.com/Product/Product.aspx?Item=N82E168... and: Matrox M9120 Plus LP PCIe x16 http://www.matrox.com/graphics/en/products/graphics_car... Thank you, Mike More about : power supply cmichael258 September 2, 2008 2:33:09 AM That PSU will easily work with those components with no problem and PC Power is a quality brand. Make sure that you choose a case that will handle it. Proximon a b ) Power supply September 2, 2008 2:33:30 AM Were you wanting to run two of those cards? The Matrox does not need the power connector from the PSU, it does not need that much power. The PSU you mention is a very good one, but it's probably more than you need.

Proximon a b ) Power supply September 2, 2008 2:44:41 AM I do not see the power requirements listed at Matrox. I do know that PCI-E is limited to 150W... So that is a max of 300W between the two cards. http://www.newegg.com/Product/Product.aspx?Item=N82E168... This PSU will give you many years of worry free operation, and should power any additional devices in your case with ease. bobbknight September 2, 2008 3:10:37 AM Ohhh get the red one it's better cause it's red. http://www.newegg.com/Product/Product.aspx?Item=N82E168... The best PSU is PCPower and cooling. Yes for you right now it is overkill. But you will be able to use it in another build later down the road. The price is unbeatable, so get it.
