Hi Alan, thanks for the input.
When I sell the computer, I'll put out the sound card so all PCI slots will be free. (will still have onboard sound)
Re the power towards the radeon9800pro: I'll check it with the new PSU. In the current PSU the situation appears to be as follows: connector that ends in radeon9800 has 3 more empty splits and a split into the P4 which splits into 2 sata, one empty and one onto the HD. In short, also the HD is on the line having the 9800Pro. Now I thought that the Trust PSU had separate sata and molex lines, so I'll just have to check not to put another apparatus on a split of the power line towards the 9800pro. This whole PSU thing is rather new to me, but I think I understand
.
As for the X1650pro: great, no PSU connector issues there.
As for the fans: sucking or blowing, as long as it keeps cool
.
Re the 12V rail rating of the Trust 5250: I couldn't find it. For the current dell PSU, it's a pathetic 16A. The Trust ain't expensive, so it won't be a 30A PSU. But I assume it can give at least 20. It can't be less than 16, on which the 9800pro runs fine as long as you don't overclock. Amazing.
The X1650pro will run on the 305W PSU of the dimension5100, but it is claimed that this PSU is underrated, which is also amazing since it's coming from Dell
. Anyway, loads of people run the X1650pro in the dim5100 and it works fine (you could even buy it like that) evne though the X1650 has 350W recommended, so as long as you don't SLI that PSU should be fine. Funny thing, SLI (crossfire) returning, hadn't seen that technology since the days of the VoodooČ.
When I install the new PSU in the 4600, I may make a question, photo and answer session here in case I'm not sure what I'm doing. Installing the X1650pro should be no problem at all. Uninstall X600, PC off, X600 out and X1650 in, PC on, install X1650, done.
