Has anyone successfully upgraded the power supply (OEM Delta 145Watt) in a Pavillion 8495 (MOBO: OEM Asus P2b-VE / Condor bios)? The proprietary nature of these units may not allow standard ATX or Mini-ATX psu's and I would like to at least up the power to 200-300Watts if possible. HP only offers a replacement of same. With CD,DVD,floppy,etc, I am concerned that any additional HDD , Sound card, AGP video adapters, etc will not have the power they need. Other than "get a new case", any suggestions are welcome. Thanks. W.P.Smith
