Ok, i have and have sold several motherboards with 4 Pin power gromet on the motherboard, im pretty sure its fro OUTPUT of powe only but does anyone know if on any boards have the 4 Pin gromet on the board is for INPUT of power.
yes, but on mine an a few other motherboards, if i plug a case fan or anything that takes the 4 pin gromet, it functions just like if i were to plug it into a lead from my power supply.
Notice that 2 of those motherboards are for ATI's Crossfire and one is for Nvidia's SLi. I found this about the Asus A8N-SLi:
Running two videocards in SLI mode draws a lot of power. To help the motherboard deal with the additional load, Asus has also placed a dedicated molex connector just above the first PCI Express slot. Of course if you're only running a single videocard, no additional power is required for smooth operation.
Thats interesting Tommy. I have a question however, what about heat? Shouldnt a PC consumer, like myself, planning on buying a dual sli system soon think about a water cooling system in addition to fans?
