I have this 430w power supply:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026&Tpk=corsair%20430Which, going by the specs says the 12V rail can handle 28A.
It's going to be powering only:
A 95w cpu (95w)
2GB DDR2 (30w)
WD black hard drive (11w)
Nvidia 8600GT(47w)
Budget mobo (50w?)
----------------------------------
Total 233w plus a keywiz, coin door LEDs and maybe an led marquee light.
I plan to rotate the monitor using a 12v linear actuator that has a max draw of 3.5A, but the monitor will be riding on bearings and shouldn't require much force to move, so I doubt it will ever pull that much current. Using an online calculator, maximum possible draw comes out to 42w.
Would it be ok to power the actuator from the PC power supply, or would that be a recipe for disaster?
Should I still be leary of doing this even with a bigger power supply?
