nmi576 Posted October 12, 2010 Share Posted October 12, 2010 Hello, Recently my PSU died and I decided to buy a Corsair product. However, there is a slight problem. There are two Corsair PSU's I was looking at: Corsair VX550W - power supply - 550 Watt 1 x power 24 pin ATX with detachable 4 pin section , 1 x power 8 pin EPS12V with detachable 4 pin ATX12V section , 1 x 6 pin PCI Express power , 1 x 8 pin PCI Express power with detachable 2 pin section , 6 x 15 pin Serial ATA power , 6 x 4 PIN internal power , 2 x 4 PIN mini-power connector Corsair TX650W - power supply - 650 Watt 1 x power 24 pin ATX with detachable 4 pin section , 1 x power 8 pin EPS12V with detachable 4 pin ATX12V section , 2 x 8 pin PCI Express power , 8 x 15 pin Serial ATA power , 10 x 4 PIN internal power Here are my comp's specs: 2.6GHz Core 2 Duo ; 4GB DDR2 RAM ; Asus P5W DH Deluxe m/b ; nVidia 9800GTX+ VGA etc. Now, I'd like to buy the 650W PSU because it might serve me well in the future (in case the VGA and/or the CPU will be replaced). However, would the 550W Corsair PSU be alright? And the problem I'm facing: My video card (the nVidia 9800GTX+) needs two 6 pin PCI-E connectors. The 550W PSU has a single 6 pin and a 2+6 pin (referred to as 8 pin detachable) whereas the 650W PSU has only two 8 pins. I don't think that these are backward compatible and could be used with my VGA. The two 6 pin slots on the card are right next to each other so I might fit one 8 pin but not the other. Also, as far as I know the 6 pin connector supplies 75W while the 8 pin does 150W so it can't be easy figuring out which 6 of those 8 pins to use even if possible... Thank you for your help in advance! Link to comment Share on other sites More sharing options...
