Seasonic Platinum 1000W Modular Power Supply Review

It is difficult not to like the Seasonic Platinum 1000W Modular, it is one of the most capable, technically proficient power supplies we have ever tested.

First impressions are positive, the bundle includes a wealth of cable ties, a case badge and a fantastic double sided storage pouch of high grade sleeved, long length, modular cables with gold plated connectors.

The paint work and styling cues are all tied into the Platinum Certification and the appearance is elegant and well thought out. The Seasonic Platinum 1000W can support up to three high end video cards, each with dual 8 pin power demands.

Technically we can find nothing to fault with the design. Seasonic have pulled out all the stops by creating a no compromises design.

Load regulation and cross loading results are class leading and actually the best we have seen since we started testing power supplies. This unit also managed to peak at around 94% efficiency, which is one of the best results yet in our labs.

Noise suppression is excellent, although the supply isn't quite as impressive as some of the other flagship units we have tested in this regard. It falls well within the tolerance guidelines, although the +12V output is a little higher than we would have expected. It is only a small point to make, but as the rest of the unit is so exemplary, it is worth mentioning.

The Seasonic Platinum 1000W can be bought from ARIA in the United Kingdom for £212.66.

Pros:

  • Load regulation is class leading.
  • delivered almost 1,200W for a short time.
  • good ripple results.
  • Almost 94% efficiency.
  • Plenty of connectors for high end systems.
  • Quality cabling.
  • pure modular design.
  • almost silent.

Cons:

  • Be prepared to pay over £200.

Kitguru says: The finest 1000W power supply on the market.
