Hi,
I was wondering if it's safe to run a power supply from an old computer (Amiga) with no load. I think it's linear? I'm assuming that because it uses transformers. Sorry, a bit new to this.
It has +12V, +5V, -5V supplies.
The main reason I ask is because I'm looking to replace the caps and I would like to measure the output noise before and after cap replacement out of curiosity.
Should I be running it under load to get accurate results anyway? If not, is it safe to run any or all of the rails with no load?
I've heard it is not good to run an PC ATX power supply with no load but I really was looking for confirmation.
If anyone feels inclined, can you explain why a load is required.
Thanks.
