I've had an antec sonata for a few years, PSU mounted up top. The door clips broke off, so decided to switch to a antec 300. PSU mounts on the bottom in that, and it seems like all the cables reach (though some barely) except the 4-pin connector, which is way up top of my asus board. Looking at the specs for the PSU on newegg, it list "1 x 12V (P4)". Is this 4-pin only needed for P4's, or is that just when it started to be needed, and still is? I can grab an extension if needed, but wanted to check first before wasting the (few) bucks. Thanks in advance!
