You are going to run into difficulty finding any mobo in the K6 series (Socket 7), that will even recognize a 1 GB stick of PC100 SDRAM.
I don't know what kind of budget you are on, but if it's as tight as mine, here's an 'ElCheapo' 400 watt PSU for $11.00...
I've got one on order now... it's got +3.3@28A, +5@30A, +12@25Ahttp://store.mrtechus.com/powmax40pows.html
You can't expect to run a Barton @ 3200+ with that one, but for your setup it'll do just fine... and it's got 25A on the 12v line.
Charlie bought one on my recommendation and he's happy with his (or was, or will be again)
Here is my new PCChips M848A' ">http://img.photobucket.com/alb...2_T-2-3-3-6-2_M848.jpg v2.1, with a 1700+ @ 2411 MHz, and my trusty old PCChips M810L' ">http://members.lycos.co.uk/mmm...00MHz_Sandra_tests.jpg v7.1A, with a Barton 2500+ @ over 3500+. Some of my fancy cars are on this pag
