In today's review we will take a look at Antec's HCG-520 power supply, which addresses tight budget users with not so high power demands. The PSU is able to provide up to 40 A on its single 12 V rail which is plenty for up to two graphics cards.
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.

Zalman, a company that is well known for its low-noise products, recently freshened up their PSU range with two new models, the ZM1000-HP Plus and the ZM850-HP Plus.
