So looks like Dell strikes again. Last time i go near one of their heap of crap systems again.
Will I be able to uprate the PSU or have they gone for yet another odd ball part?
To be fair the system is not that bad. Just that the graphica card is not upto newer games. Putting in a lower spec card is not ideal as it will be more a like for like swap rather than upgrade. WAs thinking of upto £120 on the graphics card
The Dell Dimensions, particularly the BTX based ones, aren't bad systems, as the BTX system really was (still is) far superior to the now really old ATX format. The BTX system was really a desperate requirement in the P4 era, as the chips Intel and particularly AMD were producing needed massive cooling, which meant noise, to run reliably for long periods.
Sadly, AMD did not get behind the idea, and due to slightly increased cost (based on lower volumes), only larger pure Intel shops such as Dell really used it. Those that did got better reliability.
Unless you have stuffed the system full of other crap - disks, a cd writer for every occasion, etc, that PSU should be adequate if you have just a single dvd writer and a single hard disk, unless the graphics card really is that bad.
