I listed semi-modular under both because the cables it has hard wired are all used on the sabertooth z77 with a gtx 670 so there is nothing being wasted. The cables themselves are hideous though and they could have gone with all black sleeving like they did with the modular cables that came with it. At 100+ less than the ax1200 it is worth it and if you really need individually sleeved cables there are sleeved extensions you can get for the hard wired cables from NZXT along with the upgrade kit you can buy from corsair. Great value for what is included. Sweet spot for any gaming rig.

- Semi modular
- Lots of power
- Power taing
- Design
- Not fully modular
Just a power supply. It's semi-modular design is nice, but it would've been great to have it fully modular like some of its AX counterparts.

Experience: 3 Days
Corsair quality power supply, cool and quiet operation, geat amount of power, improved efficiency over the 1000w predecessor, modular, packaging and build quality is superior to many supplies, 7 year warranty!
not much to complain about with this supply, but if I had to find something (and I'm really nitpicking here) the unit is heavy, may not fit in a smaller case, and can be pricey, but not overly so.
I was forced to purchase a new psu after my 4 year old PC Power and Cooling 750w blew up a few nights ago.
After looking for various supplies from various brands and prices I decided to spend the extra and grab this unit.

So far I have no complaints as its running nice and cool in a new 600t case powering a 2600k s 4.6 and 2x 6870 oced.

The build quality of this product is very very good. Its built like a tank, looks great and has all the connectors you would ever need. Add to this a whopping 7 year warranty (2 years longer than most psus out there) and you have a very solid working product. Reviews of this unit are mostly excellent and its easy to see why. Its not rated at Gold 80, but rather silver.. doesn't bother me none though.

Very highly recommended!! If you can get it for a deal its a very good choice.

-Supports 2 GTX 580s w/ Oc'ed 2600k r 4.6 ghz
-A bit big for my Fractal R3
-Silver modular
Bought this PSU because I was going to run 2 GTX 580 in SLI, I need the power it provides. I know it's not Gold or Platinum but it does the job pretty well.

Experience: 17 Days

Lotsa power!
Decent looks
Small profile
None yet
I haven't really tested these things to their full potential yet. I might when I add another GTX 580. Or another one. This unit has been great so far!
