Antec doens’t need extended presentation, by now, you probably have pretty good ideia about Antec and their great products.This time they sent me a EarthWatts 550w Platinum PSU for testing.Before reading the rest of the review if you don’t understand squat about PSU’s and their importance, check this tuturial by RedlinePC.

The Antec EarthWatts Platinum series are available in three different models the EA-450,EA-550 and EA-650 Platinum.

About the EarthWatts Platinum, Low Cost Power Supply series

Antec’s EarthWatts Platinum is one of the most efficient PSU series ever created. With an 80 PLUS® PLATINUM rating, the highest efficiency mark for power supplies, this PSU achieves up to 93% efficiency and gives you savings unheard of from other power supplies. By using the EA-550 Platinum, you can reduce your computer’s power consumption by 25%. A 3 year Antec Quality warranty, a whisper-quiet 120mm DBB fan controlled by Antec’s renowned Thermal Manager and CircuitShield™’s industry-leading 7 levels of protection make the EA-550 Platinum one of the best choices available. Get the power you need, save money and help protect the environment with Antec’s EA-550 Platinum!

One thing I would like to add, with introduction of this PSU series Antec intended that the Platinum effiency would be available for most  enthusiast’s and builders, because there are not a lot of 80 Plus Platinum PSU’s on the market available at this price range. Hurray Antec for that!
