Pros: -Absolute silence. I went and stuck my head next to my PSU albeit under very little load and I couldn't hear a thing. -Looks good and it comes in all black, the cables are decently sleeved too to hide those nasty coloured cables. -It performs like a 500w PSU but it can act as a 600w power supply too. I use this in my PC with a reference EVGA SC 780 and an i5 2500k, both at stock clock speeds. I've never had an issue with power.

Cons: -I would have liked the whole PSU to be modular but the only non-modular cables are the 24 pin, cpu power and one 2x 6+2 pin pci express power. Not really a bad thing since these cables cover all your bases if you plan to build a PC with a dedicated graphic card. Not going to deduct an egg for it. -Price is a bit high on this PSU but you do get what you pay for, high quality silent operation and a sleek look to go with it. -You won't be able to SLI (unless you're running some really low power GPUs) with this PSU, but that's a given considering this is a 500-600w PSU.

Overall Review: Probably the best PSU I've ever bought, I'd buy another one if I were going to build another PC in the future
