Summary: It's that I didn't go with a modular model, otherwise it's a superb PSU that runs extremely quietly and fit in my ATX mini-tower case without any issues. Plenty of connectors, more than I'll ever need, but I had to stuff the remainder in an empty bay. If you're a neat freak and have a mini-tower, you're better off with the modular so you only use the cables you need. Does have 6+2 pin PCI-e plugs as well, as some GPU's are starting to use.
Summary: My Windows 7 PC had been having strange problems for at least a year. It would completely freeze while playing music or streaming video. It would occasionally blue screen with IRQ errors. After replacing 2 hard drives and totally reinstalling I decided this was my last resort. It worked! Not one freeze up or blue screen since installation. the device itself has plenty of connectors. It was easy to mount.
Summary: i was worried that the power connector would be to short to reach my asus m5a78l-m lx plus in the carbide 200r, my other cheap 500watt didnt so now that i have this i could swap the guts of my computer to the carbide with no issue so i am very happy with the corsair cx600.
This resurrected my highly problematic Dell Studio XPS MT435!

Summary: Most of the power supplies are under powered, as I learnt from extensive online research. After my old PS would power down, power button would do NOTHING. Ordered this baby, and voila, this unit is more than capable of handling the system. To give some perspective, my old PS was abt 350W max, and barely on the borderline to power the unit (Actually no additional components were added since original purchase)..
