I have the Asus Sabertooth P67 motherboard with a couple of GPU, harddrives, and and 700W PSU.
For some time (don't remember if I made any changes or not to cause it) my motherboard have been making a beep sound continously with maybe 2 sec in between each beep.

Am I right assuming it's my PSU that's faulty?

I will upload video when possible.
 
Beep codes here.

One short beep
VGA detected
Quick boot set to disabled
No keyboard detected

One continuous beep followed by two short beeps then a pause (repeated)
No memory detected

One continuous beep followed by three short beeps
No VGA detected

One continuous beep followed by four short beeps
Hardware component failure
 
Thank you, I have read those beep signals previously but it mentions nothing about one single beep continuing while using the computer for work/games, as far as I understand.

If it's one single beep as mentioned above:
- VGA detected (I don't use VGA, I use DVI and HDMI for monitors)
- Quick boot set to disabled (not to my knowledge, but will check when I get back home)
- No keyboard detected (my USB keyboard works fine)

I'm sorry if I miss something obvious, but reading on forums and trying out solutions some far, haven't worked.
