Could I fry my LedWiz if I...

Kman-Sweden:

...wire up 5v to my LED's form a alternative power source to light some buttons when the PC is turned off?

To clarify:
I use a LedWiz and RGB-Drive™ Pushbutton Lighting modules from GGG to light my buttons while running Mame.
I planed to run some extra 5V's to some of 'em from another PSU while the Mame PC is turned off. (bypassing/not using the LedWiz)
Can I do it without killing my LedWiz and/or PC?

BobA:

Using 5V power from another PS to run additional LEDs should not be a problem for your ledwiz.

Havok:

Should be ok. In fact, external power is necessary if you are exceeding 500ma anyways...

Kman-Sweden:

Thanks guys. Just wanted to be sure since the 5V is not going through the LedWiz "the normal way".


RandyT:


You may want to show a schematic of what you are planning to do.  Unless you use a switch to completely disconnect the leds (and connect them to your external source) from the output of the LED-Wiz, it may be bad for the hardware.  An external diode to prevent backfeeding to the LED-Wiz, and maybe another on the external supply, might be prudent.
