So after taken on board what people have said regards to getting a new graphics card Asus GTX 750Ti 2Gb the thing didn't work! as didn't have a 6 pin cable from the power supply I've ordered the Trueway adaptor an also a new psu after sending my pc specs to Maplin replied this should be a good upgrade Powercool 650W ATX PC Power Supply the thing that had me worried an a headache was the (should) I scoured sites an forum's trying to find the right exact dimensions. But at end of day if it doesn't fit can go back? So suppose what I'm asking have I made an ok choice my system is HP Pavilion p6-2302eam already said what psu is. Also how do you really know if what you have received is a new item as shouldn't it be wrapped in cellophane with authentication sticker? Or am I just being picky as I don't know if it works the graphics card or not.
