Sapphire Pure 1250W Power Supply Review



Environmental Factors:

The Sapphire Pure 1250W actually scores quite high in this section and the only let-down is the inclusion of the black canvas bag for the modular cables which is really unnecessary. They come in a nice cardboard box that in my opinion is all that's needed. There is no foam used in the packaging and everything is neatly and securely packed in cardboard boxes making the majority of the packaging recycleable and the box is even printed in non-toxic vegetable oil based ink!


Price Per the Watt:

Power Supply: Sapphire Pure 1250W at $TBA = $0.XX/Watt (10-2009)


The build quality is excellent and the white LED lighting on the large chrome cooling fan will I'm sure, appeal to some enthusiasts with a liking for case lighting. The Sapphire Pure 1250W with its six 6+2 pin PCI-E connectors will easily power any SLI or Crossfire configuration using two or even three high-end graphics cards. We are starting to see the move away from devices with 4 pin peripheral (Molex) power connectors and the Sapphire Pure 1250W with only 6 of these and a massive 16 SATA power connectors reflects this trend. The modular cable connectors for PCI-E power on the Sapphire Pure 1250W power supply are 12 pin and with all the included cables utilised there is still one spare. Sapphire have pointed out in the enclosed literature that extra cables will be made available should any future developments require more than the 8 pin PCI-E connector and therefore avoid the need for a power supply upgrade.

The Sapphire Pure 1250W with its excellent electrical performance, great build quality and quiet running, puts it up there with the best and I have no hesitation in awarding it an OCC Gold award. If you need this much power or just want to install one because you can, then I have no hesitation in recommending it for serious consideration but check your case - because it's a little deeper than your average power supply at nearly 7.5 inches (190mm)!
