As the title says, I've decided to upgrade my psu and don't want to spend over £100. I've had my current PSU (in sig) for 2½ years, so I want to get something that will happily see out 2-3 years. For this reason, I'm thinking 700W and above, modular, with 4 pci-e 6/8 pin cables. Quiet would also be good!
