Guru3D Top Pick

The Platimax as such deserves a best hardware award. It is a truly excellent product that is undeniably very efficient. It has nice looks, it's a silent PSU and in fact is modular as well. Meaning you just use the wires you need. You also gain the litle extra's like the heatguard that will keep the PSU fan running for a little while after the system was shut off in order to allow for the PSU to cool down properly.
