My plans to upgrade my video card have gone awry due to the fact that every card onwards from mine requires two connections to the PSU, one 6 pin, and one 8 pin. Upon examining my own computer, I could only find one 8 pin connector, and that was connected to the motherboard. As such, I am already on a hunt for a new PSU (and I know where to look, thanks to you guys). However, (and this will show how incompetent I am), in the specs for PSUs, they don't actually list the connectors by how many pins they have. In order to make sure that the PSU has two 8 pin outputs, at which specs do I look at?
Well, I was originally going to go for the GTX 760, which requires 500W and 6-pin and 8-pin connectors. However, seeing as I will have to upgrade my PSU anyway, I have decided to instead go for a GTX 770, which requires 600W and a 6-pin and 8-pin connector. As such I just want a PSU at around 650W that has those necessary connectors (my current one only has one 8-pin, its in the MoBo).
