My computer is 4 to 5 yrs old, and only has a 200W power supply. What issues might arise as I upgrage & add more peripherals? I recently upgraded the HDD from 15GB 5,400 rpm to 120GB 7,500. CPU is Athlon 750 (with an enormous fan). Graphics card upgraded to 128MB from 32MB. 192MB Ram (upgraded from 64), ADSL USB modem, CD-RW (4x), DVD drive, keyboard & mouse fairly basic Soundblaster sound card, 1 printer (parallel laser) + now adding an inkjet USB2 multifunction device + PCI USB2 card. If an upgrade is recommended, how do you decide what size is needed?
If the inkjet device has its own power supply that should not be a problem, but the USB card while probably ok by itself should also use self powered bits otherwise things may get difficult
You can of course buy a new psu and modern jobs tend to be 300w up but with a 750 processor the time may come when a new case with new psu and a motherboard bundle (mobo, processor, fan and memory assembled and tested for around £150) may be worth thinking about. The whole lot could be done for under £200 using all those power hungry bits you have been adding
According to that website I need 320-340 min! (I'm not certain which version of the Athlon I have, hence the uncertaitny). Anyone know what the consequences might be of putting too much strain on the power supply?
