Board power connectors question

post #1 of 4
Thread Starter 
Hi guys!

I just got this new asrock 770de motherboard and i notice that the cpu power is 8pin and 24pin for the mobo. I read the manual and it states its pretty much ok to go 4 pin cpu and 20 pin mobo. What would you guys think would be better? Also, whats the difference between the 2? o_O

Thanks in advance.

My buddy has the same board, and he uses the 4 pin instead and has no problems. As far as the difference, someone else will have to answer the engineering specifics!

An 8-pin connector will supply more power, the same for a 24-pin connector. I vaguely remember reading the EPS spec. saying 8-pin + 24-pin should supply an minimum ~19 amps at 12V (230W).

If the manual says 20-pin and 4-pin are enough, then I don't see why that wouldn't work. However, a power supply with just a 20-pin connector is *very* old at this point.

Thanks for the info. I guess ill put 24 pin for mobo then leave it 4 pin for the cpu.. Im having this weird issue though... I installed my boot drive, video card, cpu and memory first. Everything was fine and dandy.. So i shut down the system. Plugged in, my kb mouse and additional HDs. The moment i powered it back on, the video card sounded it was on maximum fan speed and the system wont POST. No signal from the video card. I had to power down the system, turn of the PSU, unplug the power cable for 10 seconds and plug it back in and everything is ok again. I found out that this happens everytime i plug in a new device(e.g usb, kb,mouse,hd). Its really strange. Is the mobo possibly funky? Is it my PSU? (600 watts huntkey) Could this be caused by a ground or something?
