I noticed them on the page <!-- BBCode Start --><A HREF="http://www.rsg-electronic.de/english/prod_fr.cfm?naviklick=10&prodklick=104" TARGET="_blank">linked</A><!-- BBCode End --> from the new Recommended Parts section here. Of particular interest is the ECP230W model: <BR> <BR>The interesting thing is its quoted efficiency is an incredible 82-85%! In a computer consuming 100watts, a typical 62-65% efficient PSU might produce (100/.62)-100 = 61.3 watts of heat from inefficiency. However, if true these RSG units would only generate (100/.82)-100 = 22.0 watts! <BR> <BR>The problems are: <BR>1) It seems to use the AT form factor, not ATX. <BR>2) It seems to be impossible to obtain. <BR> <BR>If anyone knows anything further, your comments would be very helpful.

I saw it too and didn't believe it. There's not a single PSU on the market that claims any higher than ~75%. How they'd get 82-85%, I don't know. <br> <br>Tomas Risberg of TheSilentPC was the one who first alerted me to RSG & he and I both requested review samples for SPCR, to which they replied no. I could ask again...

Hi Mike, <br>It's probably not worth the trouble. I could only find <!-- BBCode Start --><A HREF="http://groups.yahoo.com/group/Silent-PC/message/3712" TARGET="_blank">one case</A><!-- BBCode End --> of a person actually obtaining one. Besides, modding an ATX connector onto it might be risky! And RSG's 300W ATX model is only 70% efficient, nothing interesting. <br> <br>Here's another find: claimed 85% efficient 170W ATX <!-- BBCode Start --><A HREF="http://www.signumdata.de/english/td_fclient.htm" TARGET="_blank">supply</A><!-- BBCode End -->. Unfortunately requires buying a >$1500 system. <br> <br>And <!-- BBCode Start --><A HREF="http://www.n2power.com/XL125bene.htm" TARGET="_blank">this unit</A><!-- BBCode End --> is a 125W PSU with claimed >85% efficiency. Allegedly, an ATX version was planned for release in Q2 2002.

That small 125 watt one is just like industrial open frame psu's like one's made by EOS. Notice that it says it still needs a fan, albeit a really low flow one.

I have a 130watt EOS VLT series one about that same size. It has a slight buzz noise, more like soft clicking. Can only hear it if you put your ear up to it.
