Feels solid, works perfectly
The construction feels very solid, no issues after 1 month. Got it cheap in a bundle, very satisfied.

Corsair (made by Seasonic from what i read), modular, quiet enough.
8 pin cable a bit short.
This is my fourth Corsair PSU but my first modular one. I got this on sale with the 300r case for 120$ and its a steal. As usual im very satisfied, altough its modular i used all the cables, the 8 pin cable fits on my system but i can see that with a taller case it woulnd be short. It drives a 2660K with Z68 board, 460gtx + GTS250 for physics, 2 drives, DVD and 6 fans. No hickups.

Experience: 3 Months
 Verified Owner
Reliable, and modular.
Works as expected and modular cable helps with internal components.

modular, quiet.
8 pin atx power cutting it a little short.
my first modular psu, nicely packed and had a little reusable pouch to store all unused or spare cables. Nice modular design, the 12v 8pin a bit short barley fit the 400r Cosair case. other than that very nice to only use the cables your need. got this with the 400r case for 150$ great deal. pretty quiet and efficient imo. good buy.

Experience: 6 Days

Runs quiet.
Have none.
This is the first Corsair power supply. So far it appears to be working great. From what I am told the PS is a Seasonic M12 which are one of the best PS made. The only thing that was wrong was the side sticker was put on wrong for placing the PS in the bottom of the case. It was put on upside down which is not a problem for me since the case its in is top mounted.

Experience: 4 Years
Reliable; modular design
Noisy after several years use
I purchased this unit more than four years ago and it's worked almost continuously (PC powered on all the time) and reliably since that time. My only complaint is that lately it is producing an electronic "buzz" (not related to fan) which now makes it the loudest component in my system. Time for a replacement.

Experience: 2 Weeks

Nice pack
8 pin too short
Regular price
Still have little buzzing noise
Is well packed, enough cables.
The 8 pin is too short for bottom PSU case, should come with an extension cable.
Fan is very quiet but still have little buzzing noise(not from the fan).

Experience: 3 Days
 Verified Owner
80+ Efficiency
8 pin cable could've been longer
A great PSU with 80+ efficiency, capability to run a single GTX285 setup (along with an OCed Q8400), and best of all, modular!

Experience: 2 Months
 Verified Owner
85% efficiency, nice modular cables. good flexibility
love the modular cables, fantastic for a good looking case with side window. runs nice and cool and doesn't heat up the ambient case temperature too much. runs my overclocked cpu,ram,gpu, and 6 case fans with ease. would definitely buy again for a single gpu system.

Experience: 80 Days
 Verified Owner
Quiet, Cabling is excellent.
This is a very solid PSU with excllent cabling. I'm running 4 hard drives, a GTX 260, overclocked 8400 and 2 DVD drives. It handles it all.

Comment: it only costs $119 and that's a heck of a value for the features this power supply has. Typical 80% efficiency, active power factor correction and modular cables!
