This power supply is built like a tank. Both the PSU itself and the modular cables are of top quality. The PSU fan is oversized and very quiet. At 1000W, this power supply should be big enough to do anything except maybe tri-SLI with top of the line video cards.

Two potential problems to look for before buying:

- One is that this PSU is longer than the usual ATX power supply. In my Cooler Master mid-tower case, I had to drill extra ventilation holes in my case's floor and remove one case fan to accommodate this beast. Just measure inside your case to see if this PSU will fit before you buy. (This PSU is 200mm long; by comparison, the Corsair 520W PSU is only 150mm.)

- The other is that the included SATA power cables do not have angled SATA connectors, so I was unable to use them in my Cooler Master case, which mounts the HDDs in the transverse direction. (I used the modular PCI cable with an angled SATA adapter instead.)

But, if you check on those two things before buying, you will definitely be satisfied with this PSU.

I've been running a custom built Core i7 920 CPU-equipped computer @ 4.2Ghz (4210Mhz) & 100% Load 24/7 since May, 2009 with a Corsair HX1000 PSU in control of the power needs of the system, and it's been working perfect all that time, never skipped a beat. It's certainly the finest, most powerful and dependable 1KW-rated (1000+Watt) power supply that good money can buy.

My build's key components are: EVGA-Classified E760 motherboard, EVGA GTX-285 1GB VRAM Video Cards x 2 in SLI, 12GB G. Skill DDR3 1600Mhz 'Purple Wonders' RAM, Creative Titanium "Fatal1ty" Sound Blaster Pro, and a real "sleeper" component that's responsible for incredible HD read and write I/O performance, an Areca 1680IX-8 Hardware RAID Controller (SAS to eSATA/SATA), and 6 WD 'Black' 1TB 7200RPM HD's in 2TB RAID "0" and 4TB RAID "5" configurations--so my Corsair HX1000 PSU hasn't had it easy with all that firepower to supply, but day in and day out it works hard, and long, and I have had ZERO difficulties with it...it just works perfect, and gives me all the power I need without fail, which is all you could ask for from a premium PSU.

I really love the modular design of the HX1000 because it makes building and maintaining a system simple, clean, and pretty nice to look at too, as there aren't a bunch of extra cables and wiring messing up the airflow and cluttering up the computer's inner workings, a real plus in my book.

I needed to upgrade my previous 750watt PSU so I could power 3 GTX 275's in tri-sli. This Corsair PSU allows me to do just that.

Pros:
Arrived fast.
Powerful yet quiet, more so than my old 750 watt Cooler Master PSU.
Runs cool.
Nice modular cabling design saves space and provides better airflow.
Has plenty of power to run multiple GPU setups.

Cons:
The only problem I have with this PSU is that sometimes when the computer is off the PSU seems to make a low volume high pitched noise. Though it is barely noticeable.

It is powering this system:
EVGA X58.
Intel Core i7 920 @ 3.6 GHz.
12GB OCZ DDR3 PC3-12800 Platinum Ram.
3X Nvidia GTX 275.
3X 500GB WD5000AAKS in Raid 1 for storage.
2x OCZ SSDs in Raid 0 for OS/Games.
TV Tuner Card.
2 Optical Drives.
At least 8 Fans.
And some other smaller peripherals.

This thing is about twice the size of a normal psu twice the power as well,
it impressed me that is incredibly silent, despite the huge fan it has
it fits in standard ATX cases, nice cabling management, you can connect
3 devices with one cable, nice design, nice look and feel, you can hold
this in your hands and feel that is a high quality product (painting, material
rounded corners, tight) it has lot of connectors, the cable bag (nice one btw)
has everything you need, i got 3 sata HD's, 2 x 295GTX gpus, 2 dvd drives, and it
keeps giving me constant voltage. Well done Corsair!!
On the other side my backup power supply 450W cant even start when energy is out but that's not a con.
You will regret buying this piece because you won't live without it!!

The package come with every thing you will need to build your dream machine. One caution, The supply air intake is at the bottom, and it may not fit the holes in your case. I used a mid tower Cool Master CM 690. About 1/2 of the intake hole is covered by the case. So far, I did not run into overheat problem yet. Otherwise, a good buy.
