Environmentally friendly with 80% efficiency

Antec today announced it has started shipping its environmentally friendly EarthWatts power supply. The EarthWatts power supplies reduce energy consumption and 80 PLUS compliant. This is the latest rating system for energy efficiency. EarthWatts power supplies increase power efficiency to 80% over the 70-75% of other power supplies currently available. These power supplies are also RoHS compliant and feature no lead or mercury in the production. Lastly on the environmental friendly feature list, EarthWatts power supplies use active PFC to reduce electrical waste.

Antec claims: "As consumers take action to protect the environment, Antec encourages everyone to look for solutions that help conserve energy and eliminate waste and pollution," said Scott Richards, senior vice president for Antec.
"EarthWatts is our most energy efficient design, and it provides users with the power and stability they have come to expect from Antec products. With the 80 PLUS certification, EarthWatts is leading the way in reducing energy consumption and protecting the environment."

Three EarthWatts models are available—380W, 430W and 500W. EarthWatts power supplies are ATX12V 2.2 compatible and feature a single 80mm. The single 80mm fan is a low noise unit. Included connectors on EarthWatts power supplies include four SATA, dual  12V and one PCIe. Pricing on EarthWatts power supplies range from $64.95 for the 380W to $99.95 for the 500W models.

I agree. I have a 350W Antec PSU powering my dual core/mid range graphics system and it doesn't struggle at all - hell, I'll go even further and mention my friends PC with a generic 350W PSU running a dual core CPU and 6600GT. I find it crazy when people recommend a 500W+ PSU "just to be on the safe side".

Maybe for a Presler (god forbid)/SLI setup, but who the hell uses one of them these days?

2 7950GX2 are at about 280 watts by themselves. If you think a Quad SLI system is gonna stay up under load with a X6800 on any 400 watt PSU you are not thinking straight. Take into account the raid array, a storage drive, an optical drive, the ram, and add in cards and you are way over your 200 watts.

GamePC did a measurement under load and got 206 w/ a single 7900gtx 512, and 288 w/ a single 7950GX2. Anandtech hit 172 without 2 raptors and without taxing the graphics card. We aren't talking about a power sipping 6600GT(~50W) or even a 7900GTX(~90W). This is a 7950GX2(~140W) aka 2 chips per card in one rig; by itself you are looking at a 300W rig under load. PSU depends on what you are buying and I don't remember seeing a single reviewer say anything about needing 500-600W PSU for single card operation lately.

Yeah, you have one card and stay mainstream/midrange 400W is more than fine (otherwise the OEMs would be in trouble), but as soon as you go high-end and SLI you start to push the envelope with cards in that class.

While I agree with you there, with a quad graphics card system, my postition on power supplies was more geared towards mainstream systems. So often people on message boards post advice about upgrading to a 500W+ PSU "just to be on the safe side" when in actuality a 300-350W PSU will suffice just fine for single GPU/dual core systems.

Oh i'm a sucker for marketing all right, but one thing I won't skimp on is a power supply and a UPS to go with it. I've replaced over 10 power supplies that i've personally put into computers before I knew the company was crap. For my own stuff especially, I don't buy what I think I can get by with and neither do most people who visit this site unless they're an up an' coming enthusist.

By the way, the 10+ PS's that died on me within warranty period were 400 Watt Powmax's that were going into Athlon 1600+ and 2000+ systems. HardOCP has a great thread if you want to know which manufacturers to avoid like the plague. After i think the first that died on me, (within a month), I never got the rest warrantied. I tossed them all into the trash and ate the cost and learned my lesson.

If you were shelling out the money for 4-way graphics, what's the price of a puny power supply?

A quality 430W supply is good enough for most economically-sane configurations: dual core + 1 graphics core.
