Fortron 400W or higher, Antec Truepower 430W or higher and Enermax 400+W PSUs.

I love my Delta 60HP 7000 RPM fan that puts out more dB then CFM :eek:

The highest efficiency I know of for supplies in that power range are the new Seasonics with the 120mm fan, about 80% efficient The Fortrons (AKA Sparkles) with the 120mm fan are similarly efficient but don't seem to be available yet in sizes above 350W.

I don't know about the other power supplies, but I do know about the TruePower 430W from Antec. It may be stable, but I don't consider 700W+ efficient. I am looking for an efficient power supply myself, but most seem to be only about 40%-50% efficient. I would like to build a small network, but I don't have a lot of power available in my apartment. I'm not going to start calling in an electrician either just to wire up more power. Perhaps there are low power solutions that available. Something that can use only about 150W input. I appreciate any help in this area.

Thank You

Enermax, Antec or toptower.
I use an enermax, as do 2 of my friends. Very good PSU. Quiet too!

Wow, it seems like Fortron is on the forefront of efficient power supplies. I read the article and it was a good read for me. I will now look them up for the smaller power supplies. I hope they can come through like they did for Tom :) 

Edit:

I just read through the article and this puzzled me a lot.

"Efficiency is measured in terms of the relationship between the output and the input power, i.e., how much energy the power supply draws from the mains in order to supply the PC system with the required electricity. Our test produced differences of up to 15%. The best efficiency, at 78 percent, was achieved by the FSP400-60PFN. With output of 397 Watts, this power supply required an input power of 571 Watts. This means that 174 Watts must be dissipated as heat."

How is 397/571*100%= 78% ?

Thanks

Good point the math doesn't work out. Some error has been made in that article.
