Hello, Right I have a biggish case with 1x 120mm fan at the top. 1x 80mm (I think) in the front and a smaller fan at the back. All work fine and my PC is pretty silent. When I went to put my new 7870 in there a few weeks ago. I struggled due to all the PSU wires all around the place. After finally getting it in the unused wires where crushed together at the bottom near the PSU its self. A few days ago all of a sudden my PC turned off. When I turned it back on it said it could not find my hard drive. So I opened it up and the 24 pin motherboard wire had been crushed against my SSD drive and snapped the SATA port off. Amazingly it still works. I also noticed it was really warm at the bottom where all the wires are. So am sitting here thinking should I ditch this PSU and go modular? My current PSU is a OCZ 750w PSU. I am thinking of getting a 550w Corsair Modular PSU. Would that be a good choice? Can you also recommend any other modular PSU's? Thanks in advance.
