7 years warranty
I bought this p/s mainly for its 7 years warranty. So far so good !

Corsair Quality
Good Value
I bought this and gave my Corsair VX550 to my son when his PSU died. I am quite happy with Corsair product quality.
This is my first modular PSU, and I am glad I went modular. The flat power cables are a bit odd as I wasn't used to them. But they worked out great.
I have this in an Antec P280 case.It's a pretty tall case and the 8-pin EPS power cable was just barely long enough to route behind the MB all the way to the top of the case. It would have made a very sharp bend in the cable right at the MB connector. An inch or 2 longer and I would have been more comfortable. So I opted to get a Bitfenix sleeved extension and it worked great.
I must note that after the second day with the PSU my PC wouldn't power up (it tried for about 1 second). I did some testing with another machine and another PSU and determined it was the HX650. Brought back the unit and exchanged it no problem (thanks NCIX). It's been working fine since.

Quality product from Corsair once again at a cheap price, highly recommended!

Another quality PSU from Corsair. This is the second HX series PSU I've bought from Corsair and I never regret a second of it. From the packaging, down to the cables, the shell of the PSU, to the actual performance. This PSU is just extremely well built and is quality top to bottom.

Semi-modular, good cable lengths, quiet.
None as of yet.
Buy with confidence. This is a quality power supply. Would say price might be a smidge high, but i got it on sale (~$90) so keep an eye out for a good price. Other than that, a great buy!

CPU + Motherboard cables are not detachable
Bought it for $90 (what a steal). I don't really see a difference between being able to remove the cpu and mobo cables and not. It's not like anybody doesn't need those two. Anyways, the power supply was super easy to setup.

If anything, my only gripe is that the white sticker is on the top of the PSU when it's mounted with the fan facing downwards..

modular sept for the 2 wires you need anyway 4/8 pin and 20/24pin
works good less wires to clutter the system has black cables the psu itself is black and blue wich is pretty nice compared to my old gray one.

Black, modular, manufactured by Corsair
Looks great inside my 600T (White), mounted directly beneath my ASUS Sabertooth Z77 mobo. Comes with many cables. Good cable length. Accessories packaged in nylon velcro bag (very nice touch). 7-year warranty (wow!).

Experience: 7 Days

Looks sleek
Very quiet
8pin ATX too small for 600t
This is probably one of the best power supplies I've owned in the day. It looks fantastic. The cables are very sleek looking and its extremely quiet. The only downside is the ATX 8pin was too small in the 600t

Experience: 6 Days
 Verified Owner
Good modular setup. and quiet.
None to speak of yet
Well made modular power supply. Good quality cables, and the fan is pretty much silent.
