Computer Shopper: Ultimate Buying Guide

This ultra-efficient 80 Plus Gold-rated power supply features a quiet, thermally controlled 135mm fan and a mix of fixed and modular cables. With four PCIe connectors and a whopping 71 amps on the 12-volt rail, it's well-equipped to run a pair of high-end video cards in an SLI or CrossFire configuration.

CPU Magazine

There is such a thing as overkill in the world of power supplies. If you're not sitting on a 130W processor and at least one high-end graphics card, then there's very little reason for you to sink a couple hundred dollars into a 1kW+ PSU. It does boast many of the same design elements as other units in our lineup an intelligent blend of modular and fixed cables, a 135mm fan for quiet cooling, and 80 Plus standard certification. Of course, the fact that this power supply is amongst the quietest in our roundup is icing on the cake.

The ModXStream Pro 500W available for about $60 dollars holds quite well against the bigger, more expensive players out there. Our tests showed that the unit runs cool. The unit stayed well within defined ATX specifications and given the price, the ModXStream Pro is definitely an attractive unit worth considering.

The ModXStream -600Watt- performed really well and withstands any of today's challenges in power management. It is definitely capable of providing 600 Watts of power [and sometimes more] at high temperatures. Although we stressed the product quite a bit, it kept itself nicely within the limits of the parameters. Although the ModXstream series can detach unnecessary cables, which is a nice feature and keeps the internals of the computer case's clean, technically it has no difference than if it had the standard non-detachable cables. The efficiency is quite common and was stable on 85% under several loads. You can find it for approximately 75 € throughout Europe which is a very attractive price for such a quality power supply. It showed us good performance and no real disadvantages and for that we kindly hand out the Recommended Award.

Dexgo (Germany)

"The first PSU of OCZ that we got to test leaves a good impression. The 600 Watt ModXStream Pro comes neatly packed with a handy bag for modular cables that are not used. The cables themselves are colour coded which helps anyone from making a faulty connection. Even though the ModXStream only has an 80 Plus Basic certification, the values that we measure are very impressive. We even measure values that came close to a Bronze certification. On top of these great figures we also found out that, when using the PSU at full load, the noise is minimal. Because of its high efficiency, great performance, and affordable price we reward this PSU with our Silver Award.

PC Pop (China)
