Very efficient
Sleeved cables
Not modular
Ugly label
Fan rattle
Highly efficient with nice sleeved cables, installation was easy, unit was stable under load. Gaming with this PSU = low power usage = savings.

Unfortunately I had to RMA this unit due to the fan making a rattling noise. It overpowered the other fans in the system and was disruptive. My internet search revealed that others have had the same problem. If you get a bad unit it's not "whisper quiet" like Antec markets the product -- not even close! It's like the low-power-state rattling you get with cheap 120mm fans, except much louder, and it can be heard outside of the case.

If you like color-matching your components: the yellow/blue label is a bit ugly, and the rear black mesh is interrupted by a large piece of green electrical tape covering a PCB component, which makes the back of your case look bad if you were trying for a black/stealthy finish.

Failed after 12 hours
Bought this for a Skylake build, I thought...80+ Platinum, high quality, reliable. Not really the case.

I installed it, ran it for about 10 hours overnight, shut it off in the morning. Came back home in the evening and the computer wouldn't turn on. Rechecked all the connections but nothing worked. Had to get computer serviced and the technicians concluded that the PSU was dead.

I decided not to get another EA550 and went with a Corsair modular 550W instead, and that is working perfectly.

Cheapest Platinum PSU, pretty quiet
Not fanless, no fan-stop mode, not modular
I had one of these in my ATX build and now I've got another one for my new mini ITX build. I had no trouble finding place for all these unnecessary cables because I have no optical drive and HDD in my mini ITX case, but it would still be nice if this PSU was modular and was not as heavy but itself. I don't know how it compares to other PSU's, but it IS rather heavy.

Experience: 1 Years
-Quite, cool running
-Nicely wrapped wires in black (+aesthetics)
The Earthwatt line of Antec products are efficient and probably the only line of products with a 80Plus Platinum rating that are sold at a manageable price. It is more re-insuring that I'm actually getting most of the 550 Watts then other Power Supplies.
