815e

I jus noticed that the Asus K8N-E has a 4-pin ATX power connector apart from the normal Big power connector.....as an owner of a 815e(yeah, 815e yeah shut up!) :oops: :wink: which has only the big connector, and as some1 who's gonna upgrade to an asus k8n-3 motherboard, what are those 4 pins...
