Summary: As usual with Antec reputation this PSU is doing its job so far and no issue with it. My Rig: Intel I5 4670K(O.C 4.2Ghz) Asus Z87I- Duluxe Corsair Vengeance Pro 16GB Antec EA-550 Platinum 550 PSU Noctua NH-U12 S Samsung Electronics 840 EVO-Series 250GB Sapphire Sapphire Radeon R7 265 2GB GDDR5
Summary: I am using this power supply in a Media Center. It is quiet and efficient both things you want in a power supply. Platinum efficiency in a power supply not only means less spent on energy cost but less heat produced for the same amount of energy. This means less fans necessary to carry away the heat. Less fans more quiet and less energy used. For the price this is a great little power supply.
Summary: Arrived on time and was exactly what I expected. This was very easy to install, with absolutely no problems. I'm an over 60 Gramma who's semi DIY I did have one of those 'lightbulb' moments when I realized '550 watts... you better start shutting the computer down', so I'm learning new habits. I bought this so I could upgrade my video card, my 300 just wasn't strong enough, and it's working just great.
Summary: 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.
Pros: -Quite, cool running, -Nicely wrapped wires in black (+aesthetics), -Efficient
Quiet, great energy saving - perfect for my 24/7 media center!

Summary: This is the best power supply I've owned for it's purpose. I have a media center PC, on 24/7 to record TV and serve as the house's audio and video distribution system. I've had this machine (in various forms) for over a decade so I'm pretty familiar with it's characteristics. I think I've had at least 3-4 power supplies in the machine over the years.... With the tiered electrical rate system we have in CA, the upper tier KW are very expensive - on the order of $0.35/KW.
Summary: I am a gamer who will have the pc on usually 7+ hours a day and with a platinum rated power supply I'm getting 91% power efficiency at 100% load which is means only 9% is gone to waste. 80+ standard is 80%+ efficiency at 50% load however this one does 93% at 50% load It is expensive, but I will eventually make but the saving in electricity!
Summary: Des condensateurs chinois sous-dimensionnés. Un repiquage de l'alimentation PCI Express, un ripple élevé. Bref, une alimentation FSP qui ne respecte pas votre matériel, avec un prix pas forcément donné non plus.
