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...
Yellowbeard Posted October 13, 2010 Share Posted October 13, 2010 Our 8 pin PCI-e plugs are actually 6+2 connectors. They will work in a 6 pin or 8 pin GPU plug. Link to comment Share on other sites More sharing options...
nmi576 Posted October 13, 2010 Author Share Posted October 13, 2010 Ah, that's great news. I wasn't sure what to think to be honest, for example one of my friends has a Corsair CX400W - the specifications page tells you it has a PCI-E 6 pin but the image shows a 6+2 connector. http://www.corsair.com/products/cx/default.aspx + select the Resources tab on the top (when he got the power supply, it only had a single 6 pin plug) This is where my confusion originated. Thank you for your help, I ordered the 650W model :) Link to comment Share on other sites More sharing options...
