Today we are looking at three supplies from companies that are catering to exactly this market. Let's take a quick look at them.

Enermax Coolergiant NoiseTaker EG701AX-VE(W)
Price: around ?05

This snappily-named unit is rated to 600 W, and is a pretty nice looking box. A hard-lacquered blue paint job is set off by some huge gold fan grilles. The supply has two fans and a variable speed control for noise adjustment, which worked as expected. Interestingly, the unit has a circuit that keeps the fans running for a couple of minutes after the computer has been shut down, to prevent overheating.

The supply has a new-fangled ATX plug, which means that whilst it will fit into old-fashioned ATX boards, it's designed for newer PCI-Express units primarily. In keeping with this theme, it's one of the first to include a PCI Express graphics power connector on the card, so that your 6800 never need be without the juice it needs. SATA connectors are, of course, de rigeur.

Taking the unit apart, the Enermax has the best build quality of any of the units here. Heavy duty heatsinks accompany some quality wiring. The unit feels weighty, and we are impressed with the length and quality of the cables both inside and out.

OCZ Modstream 450W
Price: around ?0

The OCZ is a cool chrome. Like its competitor, the Ultra X-Connect, it allows users to select what cables they want in their machine by allowing for cables to be detached and attached as required.

The unit sports a single 120mm fan, which is pretty nice and quiet. The back of the unit is grilled for ventilation. The ATX connector is pretty novel, allowing for the extra 4 PCI-Express pins to be slid onto the main connector as needed. Like the Enermax, the adaptable OCZ cables allow for SATA and PCI-E graphics connections, however unlike the Enermax, we found the ATX cables a real pain in the behind on this PSU: they are far too short, making them consequently far too rigid to move around in a case to suit the different placements of ATX sockets. The inside of the OCZ belies its cheap price point - the build quality isn't up to much.

Hiper Type-R 480W
Price: around ?5

Possibly the most extravagantly packaged supply we've ever seen, the Type-R comes a plastic crate complete with handle, which after unpacking, could double as a tool-kit for all those loose screwdrivers and spare screws one always has laying about. The Type-R is available in a variety of mod-friendly colours, including silver, black and this tasteful shade of red. Maximum ventilation means an all-over grille body, with only a quiet 120mm fan sitting on top.

Funky red plastic suffices for the connectors, which sadly lack a graphics power connector. Fantastically, the molex connectors have quick release clips to make plugging peripherals far easier. Annoyingly, this is a real pain for graphics cards, which have the molex plug mounted flush on the PCB - you may want to consider using a molex passthrough wired with standard plugs for your graphics power. Thoughtfully, however, Hiper include an adaptor to convert the larger ATX plug into a more common 20 pin variety.

The inside of the Hiper unit is almost as good looking as the Enermax, but not quite.
