Corsair PSUs go for gold

If you're looking to power up a potent gaming rig then Corsair's new line-up of Gold PSUs could be just what you're looking for.

With the ability to provide up to 1.2KW, the new power supplies aren't only suitably strong, but they're also very efficient.

So efficient, in fact, that all three of them have been awarded with the 80plus Gold badge, meaning they must be able to hit 90 per cent efficiency at 50 per cent load.

Corsair originally unveiled the Gold range at Computex this year, but the company has now started letting the units out of the factory gates and into retailers.

Three models are available, all of which feature a modular cable system and a colossal single +12V rail to ensure you always have enough power for your CPU and graphics cards.

At the top of the stack is the monstrous 1.2KW AX1200, which has a gargantuan 104.A rail and six eight-pin (6+2) PCI-E power connectors for hooking up multiple graphics cards.

It's a veritable beast of a PSU too, measuring 200mm long and featuring a large 140mm fan, which Corsair claims is both quiet and effective. There's a huge choice of cable interfaces too, including 16 SATA plugs, 12 old-school Molex connectors and a pair of floppy drive plugs.

There's a bit of a jump down to the next model, which is the 850W AX850. This has a shallower length of 160mm and only features a 120mm fan, but it still has some pretty beefy specifications. In this case, the +12V rail is rated at 70A, and four eight-pin (6+2) PCI-E power connectors are provided, making it ideal for rigs with two high-end graphics cards.

Finally, the 750W AX750 sits at the bottom, sporting the same dimensions as the AX850 and featuring a 62A +12V rail. As with the AX850, four eight-pin (6+2) PCI-E power connectors are also provided for supplying power to a pair of graphics cards.

You have to pay a price for 90 per cent efficiency, though, and you won't be surprised to learn that the Gold PSUs aren't cheap. The top-end AX1200 costs a whopping £239.99, although AX850 and AX750 are slightly more affordable at £156.99 and £136.99 respectively.
