Introduction:

A 1000W computer power supply is now available from most of the major power supply manufacturers. Do we really need them? Six months ago I would have probably said no but with the advent of the GTX 280 and 4870X2 in dual and triple configurations, and with power requirements exceeding 500W, I feel they can now be justified. You may very well think a 1000W unit is overkill but if you have enough funds to buy a power supply of a higher rating than you actually need then I say go for it. Most power supplies operated at, or about their half power rating will run at their maximum efficiency, produce less heat and consequently run quieter with lower fan speeds.

Corsair have been a leader in the manufacture of high speed memory modules for mission critical servers and high end workststions since 1994. In more recent years they have used this expertise to produce a range of high technology products for the more mainstream computer enthusiast. Corsair, probably best known for their high quality memory modules also produce a range of quality computer power supplies, liquid cooling solutions, and flash memory. Let's have a look at what could be considered their flagship power supply the HX1000W.

"The HX1000W joins the family of well received HX series enthusiast grade power supplies known for their rock solid stability, enhanced modular cable design, and high efficiency. The Corsair HX1000W power supply sets a new standard by which all other high wattage power supplies will be judged.

The Corsair HX1000W features six PCI-E connectors, both 6 pin and 8 pin compatible, to power multiple high-end graphics cards and two EPS12V connectors for dual CPU configurations. The truly independent dual transformer, dual rail design allows for optimum load balancing resulting in greater performance and stabilty. Industrial grade 105°C primary, secondary, and solid state capacitors provide up to four times the lifespan of traditional components.

The HX1000W not only delivers one thousand watts of clean power for the highest performance enthusiast systems, it does so at greater than 80% efficiency thanks to the double-forward switching design and multiple rail DC to DC convertor. Due to its best-in-class efficiency the HX1000W is able to run cool and quiet with only a single 140mm thermally controlled fan."

 

Closer Look:

The artwork on the Corsair HX1000W packaging very much follows the theme and layout used throughout their power supply range. The HX1000W packaging uses a blue and black colour theme to good effect. The top cover gives us the model number and an arty photograph of the power supply. It also has logos telling us the unit has a five year warranty, is SLI certified, and complies with the 80 Plus specification. The underside provides us with a wealth of information including special features in five different languages, the output specification label, and an audible noise against output power graph. Down in the bottom left hand corner we have logos of the various test house and agency approvals.

 

 

 

 

 

A list of features in five different languages on one side and photographs and quantities of all the available connectors on the other.

 

 

Large model number logo on one end panel and a short introduction to the power supply, again in five different languages, on the other.

 

 

Lift the lid and the power supply is neatly encased in a foam envelope for maximum protection against transit damage. Remove the top foam lid and we have the power supply further protected within a plastic bag. Tucked neatly down the side we have the bag containing all the modular cables.

 

 

The Corsair HX1000W, as you can probably see in the photograph, is a little longer than your average power supply and this extra length needs to be taken into consideration when planning an installation. The modular cable case shown along with the power chord, case screws and a quantity of cable ties to help with your cable management. The black paint finish of the HX1000W is a slightly textured finish and is complimented with a black fan grill with the Corsair logo at its center. An instruction manual was not included with my review sample and I can only presume this was an oversight.

 

 

Good quality packaging containing a wealth of printed information along with everything you are likely to need when installing the HX1000W.
