So I recently purchased a new PSU and GPU, after being advised on some solid upgrades my off the shelf desktop, but I have run into some issues fitting the PSU and haven't fen attempted anything with the GPU yet!
The PSU is a Corsair RM 550, fully modular. And my PC is a HP Pavillion P6 series. The main issues I'm having is first the actually PSU is about an inch longer than the original, then with the cables out e back I'm struggling to place the disk drive back in place, and secondly, which I believe may be a bigger issue, my motherboard has a 4 prong connection for the ?CPU (I think this is the 12v part?) and the cables don't come with any 4 prong connectors.
What can I do? Am I screwed?
