3years old and still strong, this unit is fantastic!
It has poweres my rig through countless upgrades. Firstly 8800gtx in SLi, the 460's and now 2 gtx 580's. It is rock solid!
I cannot fault this PSU.
Thanks, as always to overclockers for good service, and bringing the joy- 5 stars

HX 1000W

Amazing PSU, no noise, simple installation into my HAFX case and looks the part too.

Only word of warning is cover the fan if your installing it into a new build as I lost a screw while building the PC. After searching everywhere for hours and shaking the PSU upside down, nothing. Shrugged it off and gave PSU one last big shake and out comes the screw (stuck to a magnet). Would have made a big bang!

Corsair means Business!

I got this PSU instead of Antec Quattro 1.2kW and I must say I felt a huge relief when it arrived less than 60hrs later (note I'm from Dublin).
I must say, I became sceptic about Antec's because my previous TP480W failed after 3 years of service (faulty capacitor - no power-up) and my 1-year old TP750W is barely coping with newer version of VGA's like GTX2xx >X4xx - especially in SLI mode :/.
I also found out that the first models of TP750W "weren't" fully capable of handling x58 MBs and I have one :/. My MB when powered was generating hig-pitched noise in standby/sleep mode.
With this PSU in place I hear no noise and I feel confident knowing that my hardware has enough power to run smoothly.
The reason why I pciked this PSU is I read a lot of reviews about HX1000 and HX850W and both should be cosidered in first place when looking for an upgrade or new PSU!
Big thanks to OCUK for prompt dispatch and service!

Top Notch

The cabling is excellent and is very quite i am running my i7 at 4Ghz on this psu and 2 x GTX480'S the HX1000 is a excellent choice for todays market in highend pc's

Using my kilawatt was only drawing about 740-778w outstanding

Nice one

Well reading the review below ofcourse this is not the best psu in the world.
things like enermax 1250w evo and revo, silverstone strider and tagan own this.
But is a very good 1000w solid psu, for handling your latest hardware like gtx 480's, i7 980x overclocked etc.
Highly recommended if you cant find any higher 1000+ psus.

I firmly believe that at any budget for any gaming system using a top end card or 2-3 top end cards this is the best psu in the world. The package you get is truly complete. I feel more confident about this lasting literally forever than any pc component i have ever bought.
