PSU compatability question

Okay, the only reason this is even a question is this is something I would NEVER try in my profession for a clients rig, but am considering doing to one of my test rigs here at home. Here's the background:

I have an Aspire 520 watt PSU currently running my daughter's rig (aka frankenstien) and it's the somewhat older 20 pin ATX style connector. It does have the needed 4 pin 12v extra power connector, but the motherboard I want to hook up to it needs a 24 pin ATX connector instead along with the 4 pin 12v. When I line up the PSUs main power connector over the motherboard's power connector, I can see that it would work offset with 4 holes unfilled at the top side. My question is this, can I hook up this PSU to my Asus A8N-SLI Deluxe and it work safely if those 4 holes are left unfilled? Do I HAVE to use an adapter? I've seen one too many results of older Dells and mismatched PSUs to step into this one without consultation first.
 
I'm using a lowend Foxconn 939 board with an older PSU with only 20pin ATX and 4pin 12V connector. It runs stablely, with a 15% OC and 10% overvolt to the CPU. AFAIK the adaptor doesn't actually do anything since it can't increase the amount of power the connector wires can deliver safely. Your asus board might have higher power demands, but I don't think you have to worry about anything other than potential instability, which is easy enough to test for.
 
Thank you :D

My test rig's PSU went belly up, and so am dropping my daughter's PSU in the test rig for the time being. I figure my daughter can play her games on it for now.
