sure. 400 W is plenty for this, even with (single) video, you will not 
run into trouble. Let's assume your quadcore will draw 140W Max from 
your PSU and a decent lowend video card (which you do not have!) will

You will not need this for testing purposes. Use any power supply that 
you have. I would suggest that you start with a "known working" power 
supply to differentiate causes for problems.

Do I need the DVD and HDD installed to boot to BIOS?
On another note DVD, HDD and the like do not draw any reasonable power 
that is worth to be discussed. Simply forget about their power consumption.

This does not matter for boot up to Bios. That can be done without any 
DVD/hdd at all.

If for some reason you want to connect SATA for testing, there are 
adaptors available.

I assume you are referring to the (nearly) square connector...

It should have one. Have a look. If there is none, the PSU might be to 
old to be used for your testing purposes.

Try and find out. Over here that works, although I just use torrent for 
Linux DVD /openoffice.... downloads, so I cannot comment on different 
contents or torrents.

Kind regards and good luck with your ASUS board.
