lots of power at 1000w
good warranty

This is pulling 650 watts from the plug and it is running very cool with an almost silent fan. It replace a 750 watt PSU which was always running hot. Definitely recommend this PSU.

1000W if you need headroom
Made in China
Yate Loon fan
80% efficiency
No 80 Plus certification
Bought this power supply after reading the review from JonnyGuru, reviewed 4 years ago. Certainly not an electrical engineer so you have to take your chances with their words not knowing their qualification(s) or creditability. Don't know if Corsair made any improvement to the power supply over the past 4 years but at least they could have make the power supply to look like Seasonic X-series.

Whisper silent, no electrical noise, more then enough connectors
Some of the modular connectors were a tad bit shorter then I would have liked and the non-modular ones are a bit bulky.
This psu is completly silent, my system is quite and I can't hear my psu even if I put my ear right next to it. More then enough connectors then anyone will ever need but as said before they are a tad bit short for perfect cable managment in my cas (haf 922). Overall a great product even though it's regular price might be a little steep, for what I paid it was a sweet deal.

Lots of power
More effective power consumption
Great product for a good price its hard to beat. Would buy another if I needed the power. Cables are good quality and the modular cables are pretty handy and gives it a clean look.

Excellent, when it works.
Don't know if it's just bad luck, but the first one only lasted a week. NCIX's RMA process was awesome though! BUT the replacement just died today! I shut down the computer through normal Windows shutdown, go to turn it back on and NO POST. I don't have any heavy load, maybe 600 watts of total load. Single video card etc. I really like Corsair branded components but this is giving me doubts on this model. Hopefully Corsair will replace with something different and more reliable. Strike 2 in 2 months, Yikes!

- Powerful
- Quiet
- Plenty of modular cables included
- Modular cables are flat ribbon style, harder to bend.
- Ferric noise filters increase bend radius
- Very long PSU, check your case. May block fan intakes.
The HX1000W I purchased based on Corsair's reputation and also many different reviews from the internet. My opinion matches - great product, quiet and plenty powerful. Be advised however, the PSU is quite long and may end up blocking fan intakes on the bottom of your case. As well, this length may blocks out some of the side cable entry ports on the mobo-tray. (I have a CM690II)

Cables w/ ferric adapters are great, but keep in mind they will slightly increase your bend radius, so if you have long video cards with connectors in the front/on the side, be careful.

quiet , lots of power , as long its not DOA
First one died on 3rd POST, but since it was a NCIX build machine RMA took one day , great support
I went for new system and with a full tower Thermaltake case I will have a lot of hard drives ( non SSD) so want to make sure I have power for them and eventually a Crossfire set up. Had my fun with OCZ so went Corsair this time and hope the first DOA unit was just a fluke

Experience: 5 Months


-lots of power
-nice black finish
Not fully modular
I'd almost want to call this a work of art, it runs so silently it's not even funny and can still un SLI 580's and whatever you can throw at it.

Comment: The Corsair HX1000W is not only one of the best performing 1000w+ power supplies we have seen to date but certainly the best built consumer 1000w power supply in this price range, if not overall.
