ENERMAX Platimax 1200W Power Supply Awards & Reviews

Hexus Wish List

1,200W PSUs are all about offering the real enthusiast the utmost flexibility in connecting a wide range of power-sucking components. The fully-modular PSU can power up to four high-end graphics cards. Meanwhile, lots of SATA connectors make storage easy, so it's a good fit if you plan to run a monster rig full of graphics cards and storage drives.

PureOC Editor's Choice Award

The Enermax Platimax 1200W is a beast of a power supply, it's not only stylish, but it's also strong and durable, and can handle a highly overclocked processor, as well as dual GTX 590s in Quad SLI without breaking a sweat.

Kit Guru Must Have Award

Technically it is a solid design and features stable load regulation, great noise suppression and high levels of efficiency. Noise levels are low, and the quiet, yet capable fan ensures that internal cooling proficiency is without question. It also passed our cross loading stress tests with flying colours.

PureOverclock Editor Choice

A phenomenal PSU that will power any enthusiast system while maintaining fantastic efficiency.


The Enermax Platimax 1200W is the largest 80Plus Platinum rated power supply we have seen. This is a testament to Enermax and its products. It does however very much compare evenly to Enermax recent MaxRevo 1350W. Both units feature the very best build quality we have seen from Enermax, excellent regulation on the minor rails, and extremely good DC Output Quality. The Platimax 1200W pulls a bit ahead of the MaxRevo 1350W in efficiency and noise output but it still has the same loose 12v regulation that we have seen previous Enermax units. Ultimately, the Platimax 1200W is a very solid 1200W unit that by the numbers is the most efficient on the market at this output level.
