While most enthusiast power supplies appear to be kitted out with a single mammoth-sized +12V rail these days, OCZ has proved that there's still room for the multi-rail setup with its latest range of StealthXStream 2 PSUs.
Aimed at the lower-budget end of the gaming and enthusiast spectrum, the PSUs all cost well under £100 and are rated between 400W and 700W.
Although none of the PSUs have SLI certification, OCZ reckons the 700W and 600W models will kick out "sufficient output to power dual-GPU platforms." Both these units feature four +12V rails rated at 18A each, and also come with a pair of PCI-E power connectors; one six-pin and one eight-pin (six plus two).
The 400W and 500W units feature just two +12V rails, again rated at 18A each, and just a single six-pin PCI-E power connector, which is enough to power a Radeon HD 5770 graphics card.
All of the power supplies feature the basic 80plus certification, guaranteeing at least 80 per cent efficiency, and they also come with a newly designed 120mm ball-bearing fan, which OCZ keeps the PSUs both cool and quiet.
OCZ says the PSUs are aimed at the, "minded consumer seeking quiet performance and an understated design," pointing out that a StealthXStream 2 PSU is "virtually silent and excludes flashy LEDs to ensure it is not seen or heard."
All the PSUs feature a fixed-cable design, rather than a modular cabling system, with the 700W unit featuring six Molex connectors and six SATA plugs, while the 600W unit has five Molex connectors and three SATA plugs.
At the lower end of the scale, you'll get four Molex connectors and three SATA plugs on the 400W and 500W units. All the units also come with a four-pin floppy power connector.
There's no word on pricing or availability for the 400W unit, but the rest of them are all available now. You can pick up the 700W unit for £73.99, the 600W one for £66.99 and the 500W version for £57.99.
