my case didnt have that much room in the back. i was going to get a nonmodular but found this on sale. glad i did because otherwise i would not have enough room to close my side panel unless i spent another hour or more.

- Good price
- Silent
- Solid, cable module
- cables clearly marked
- not every cables are modular
Bought this to replace my old TX750 which had the 3.3 rail failing under OCing. Buying that PSU solved this and system running stable after it, running full OC cpu with OC SLI cards.

My only complaint is the modular cable management where I wished all the cables (except the MB of course) could be single managed. I had a last cable to hook and I had to take one that has like 3 molex tied to it leaving 2 useless.

Excellent PSU, well built, should be happy with the purchase.

Quiet and powerful.
Cables are a bit of a hassle.
I really do have no complaints about this PSU, but if I had to, the wires a bit rigid, so, maneuvering them into place can be kinda tricky.

Otherwise, good buy.

-Built like a tank
-Works fine so far
-Looks sexy in my case ;)
-Not very many cables are modular, but I don't have any cables laying around.
-Some of the cables are a bit too short (I have an E-ATX Case) so I can't route them through behind my motherboard tray.
A quality built power supply. Glad I went with the modular version, worth the few extra bucks!
