I have an old 2001-02 hp computer
I have been keeping it for parts.
What is the average voltage and wattage of one of these things?
I have a 48v 300cfm .49amps fan I was trying to figure out how to power.
So i can use a power supply to test all my little IC projects?A computer power supply should have several different rail voltages: +3.3V, +5V, +/-12V:
I was thinking of the same48 volt supplies aren't as easy to find as 5 or 12 volt ones. They are available, but can be expensive.
Radio Shack sells a 25 volt 450 mA transformer for about $6.50. If you bought two of them, wired their outputs in series with the right phase then you'd have about 50 VAC. Rectify that and you could run your fan.
