Is it a bad idea to jump a psu without a load on it?
I read this guide. and it says that without load the psu could blow up. Just curious to second opinions.
 
I have a old Acer power supply that I use to test fans and such. Ive ran it hours with no load and its never had any problems.

I KNOW if you run like 4 12V things ONLY on the 12V rail that it wont work, you need to balance a load on the 5V rail to get the PSU to operate.
 
Modern ATX PSU's have very small dummy loads built into them. Most have for the last dozen years or so, although I've heard that some really, really cheap ones may not.

I can't imagine how cheap a power supply has to be to not have a dummy load because I've paper-clipped power supplies as cheap as Powmax and Deer with absolutely no incident.
 
I've done that dozens of times with various (uber-cheap to expensive) powersupplies and it causes no problems. Doing it for extended periods should cause no problems either.
