A power supply from a PC should start up when the mains is plugged into it? It draws a little power from the mains - at least there is a spark noise when the lead is shoved in live, but its fan doesn't start up. There is no voltage on the green lead that I gather is supposed to be +5v and driven low to switch it on Plugs from it are a block of 8 and a block of 24 - ATX isn't it.
Sounds like the newer ATX standard, I'm pretty certain the wife's PC has a 24 pin connector plus an 8 pin power (although it's only got a 4 pin connector in there and it works).
My room is so quiet at the moment though that I may be in the market for a new machine that has less howling fans. Old one is a Dell Poweredge 1850 and I use grahics cards in PCI-Express slots. What does the panel like for hardware these days?
Depends what sort of performance you're looking for. I've got an eMachines ER1401 which I picked up for £110 from the eBay outlet, ran Linpus Linux until I replaced it with Ubuntu (10.04), works pretty well although it's a low spec CPU (Athlon Neo N37 I believe, 1.3GHz dual core) with 2GB Ram and a 250GB hard drive. Has VGA and HDMI out and it's so small it'll mount on the back of a monitor/TV, it's whisper quiet too, or at least I can't hear it. It's fine for web browsing and whatnot.
Otherwise if you want something more powerful, AMD have released the new Fusion range of APUs (CPU and GPU one one chip) which support CrossFire so they can be used with a mid range graphics card to improve graphics performance.
You could also replace the fans for quieter ones. Rob -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
