FSP Aurum CM Gold 750 W

FSP decided to enrich the successful Aurum series with three new models that feature more wattages and a semi modular cabling system. The latter will be of great interest to many, since nowadays more and more users seek a modular PSU in order to avoid the extra effort needed for cable management with non modular units.

Antec's High Current Pro HCP-1200 is famed as being one of the best high-end power supplies on the market. With 1200 W capacity it's a great choice for systems with three or four graphics cards. We took Antec's flagship for a spin with our upgraded, fully programmable, load tester. The $250 HCP-1200 powerhouse performed admirably, and we love it.

Antec's High Current Pro 750 W is the smallest member of the High Current Pro Series which is Antec's flagship line of PSUs. The mighty HCP-1200 is well known for being one of the best power supplies on the market, so we wonder if the 750 W version can impress too.

Zalman ZM1000-HP Plus 1000 W

It's a common truth that high wattage PSUs and low noise levels do not get along very well, so many users are forced to buy lower wattage PSUs that cannot support a powerful system with two or three hi-end VGAs. To address this, Zalman's ZM1000-HP Plus 1000 W uses heatpipes to lower the fan's RPMs and minimize noise.
