I am building a system based around an old Dell Precision 450. It has two P4 based Prestonia Xeon processors in SMP running at 3.066 Ghz with HT. I have inserted an old AGP Nvidia 6800GS. Since the system lacks on board sound, I am also installing an obsolete Creative Labs Creative SB Live! sound card. I would also like to run a 40GB and a 75GB 5400rpm IDE drive, as well as two CD-R/W drives (also IDE). Audio output will be supplied by leftover USB headphones. The system also has a floppy drive that it came with. I have not yet removed it to examine it and so cannot provide an exact type.
My question is this - is the 360W power supply that the computer came with sufficient to run the system described above?
As this project is purely for my own amusement and is constructed entirely out of parts I have lying around, I am unwilling to spend any real money on this system. I do, however, have an old 450 W power supply that I have wired to turn on without being connected to a MOBO. I could use this to power some components. I understand the graphics card is likely to be the biggest power hog (besides the space heaters they call P4 Xeons). Having said that, if more power is required, which components would be best to run off a separate PSU? Please understand that I would prefer that it be secondary components if possible (Secondary HDD, CD-R/Ws, etc).
This computer has a very uniquely shaped PSU, so simply upgrading or replacing the primary PSU is NOT AN OPTION. If a secondary PSU is used, it will reside outside of the case so additional heat will not be a concern. Please undertand that I am fully aware of the limitations of this system; it is a for fun project only.
Thanks very much for your help and sorry for the novel-length post!
