Topic: How much power can I draw off the +5 rail without problems?

[dabone]

I'm looking to add a internal wireless serial terminal server to my 128, it will need about 700mW of power.
I am using a 3.3volt regulator to power it, and was hoping to draw the input 5v from the computer.

Now my flat 128 power supply is rated for 4.3a on the 5v, but I've read that some are only rated for 2a.
(I figure the c64 is right out with a stock power supply.)

Can I draw the required load without hurting a standard supply?


I'm also running a uiec from Jim Brain internally already.

Thanks,
dabone

     You should be able to power it without problem.

I'm also running a uiec from Jim Brain internally already.

     IIRC, the most power that a uIEC takes is 40 milliamps.

Like Big R said - you're fine - it should be more than enough....
