I've just done this myself, to breathe some new life into my Precision 390, The processor was and still is a Quad Core Extreme QX6700, Ive uprgraded the Ram from 4gig to 8 gig, put a crucial SSD 300 series 256gb boot drive in and upgraded the graphics card to a Quadro 4000 also moved from Windows XP to Windows 7 Ultimate......I now have a windows base score of 7.2 which I think is not bad........HTH Sean
Yes I did use the stock 375 watt PSU and all was fine, then about 6 months later i put in a Corsair Modular PSU s I wa instaliing more hard drives, the corsair PSU just fit but not all the screws would align.....Ive now upgraded the computer to a i7 so no longer have this Dell 390. HTH sean

did you use stock 375 watt psu? if you upgraded the psu, did you use standard ATX?
