There are many threads that still say you need a load. But I'm just going to use my psu tester anyway, as a way to get the psu to turn on and have a cool lcd status. If it gives it a little load then maybe I also avoided another problem.
Instead of people shorting the power on wire and/or using a load, why not use a cheap tester like this to do 3 things at once?
Topic: PSU stand alone 5v load (Read 1808 times)
I suspect it's a thing of the past.
So this begs the question does one really need to have any other voltage loads on a modern PSU used as a standalone unit?
If the voltages all come from the 12v rail do we have to hook up hard drives or lights to get a solid 12v under heavy load.
It seemed that the consensus was something was required, is that not so anymore?

I can tell you the Rosewill Capstone 650W PSU doesn't need anything other than the PG signal grounded to produce correct voltages.
I knew D&T would comment on this thread 
Modern DC to DC PSU don't need a load on 5V "rail". All the AC power is converted into 12V and other voltages (like 5V) is supplied from the 12V.
Some older PSU:

I very very very seriously doubt your voltage tester is pulling 100W. Is it as hot as touching a 100W light bulb? The voltage it is using depends on where you have it connected. If you have it connected to a MOLEX (4 pin) connector then it is putting a load on +5V & +12V rails. If I had to guess I would say it is probably <5W.
Some older PSU:
Code:
|----- 12VDC
120V/240VAC ------------ 5VDC
|----- 3.3VDC
Modern PSU:
Code:
120V/240VAC ------- 12VDC ----------- 12VDC
|------------- 5VDC
|------------- 3.3VDC

Why do I need a load? I really don't want extra crap hanging off.
I have a PSU tester that plugs into the motherboard cable. It turns it on and gives it a load. I think its the perfect solution plus I get a cool LCD to see PSU stats live. I just wonder how much of a load it is driving. Am I wasting 100w? What volts are being loaded?
Is this a good idea to get the psu to turn on and give it a 5v load?
