I've been digging through 80plus.org trying to find high efficiency power supplies for my new build. It is a light gaming system that'll likely not need a ton of power. I'm thinking 350W supply would be fine. Does anyone have any good suggestions?

Corsair VX450W, 80Plus certified and reviewed on SPCR.

Hi,

My default PSU is the Fortron Source "Green" 300watt -- it is ~80% efficient, very quiet, and inexpensive:

Just got one today. Can't really tell any dif from the 300w seasonic. (it looks like a clone or generic version.)

Nice deal. thx Neil

I was looking at the SeaSonic S12 II SS-330GB 330W. Its a bit more efficient than both of the others posted. Any other ideas? Are there any supplies out there that are around 300W and have 85+% efficiency?

I would look at the OEM Seasonics - SS-350ET & SS-400-ET. They're not as quiet as the retail units, but they're the only 80Plus PSUs in their price range.

The 330GB is the same price as the 350ET on newegg atm with a $10 instant, and $10 mail in rebate.

I also found the Rosewill RG530-2. Average efficiency of 84.1% vs the 330GB's 82.7%. Looks to be the same price currently minus the 330GB's $10 MIR. Anyone have any info on the Rosewill?

Don't do it. It's a rebranded something or other. I would not trust a low-name brand to be honest or accurate with all the specs.
