I just purchased a XFX ati radeon 5750 for my gateway. it's running a intel i3 processor, with 8gb of ram and a 1tb hard drive. This computer didn't come with a graphic card so i'm wanting to upgrade cause i'm graphic designer and i need to capiblities. I also have on order a Seasonic s12II 520 Bronze psu. after i ordered i started reading and i don't think that this psu will work it doesn't have 2- 6pin connectors. can someone help me out i know nothing about all of this. i usally by computers with video cards so this is all new to me.
The TDP of even the 6770 is 120W? 130? If it gets 75W from the motherboard, you only need one 6 pin plug to provide the other 45-55W. There is no way the 5770 would have two plugs, as it would then be a 225W card.
