Antec Earthwatts EA-550 Platinum review

12 February 2013
  • Excerpt: The Antec Earthwatts EA-550 Platinum is an 80 Plus Platinum certified PSU, which guarantees its efficiency to be around 90 per cent at all loads. In other words, that's a guarantee that this supply is going to be cheap to run. The certification was proved correct in our testing, with the PSU managing 91.31 per cent efficiency at 100 per cent load, 92.86 per cent at 50 per cent load and 90.76 per cent at 20 per cent load.
