I have all the components for my new build except a new psu. My old one has never failed me, but it does nto have a 24 pin power connector. So my question is should i wait with putting together my system until i get a new powersupply, or should i just connect the 20 pin one and use it for a week or so? Im opting for the second option because i dont want to wait.

How much have you spent on the components? And you are willing to risk something getting damaged (possibly) for a week??? Meh, wait the week...

True, It was just that i read in a magazine that if you connect a 20 pin to a 24 pin, the only problem would be stability, it didnt say anything about damage.

Worst that can happen is it will be unstable, but even that seems to be a rare occasion. No harm in trying really, if you are worried about overloading the wires just check how warm the wires near the socket get after running for awhile.

I would use the 20 pin power supply - unless your new rig is a dual 8800GTX power hungry set up.

Some motherboard companies (i.e. DFI) will not honor any warranty or support if you use a 20-pin PSU connector or a 20-pin to 24-pin converter on one of their mobos that specifically state that it requires it. Something to be forewarned about...

My main rig is a an nforce 4 mobo with a Athlon X2 4200+, 2gb of ram, and an x1800xt. The mobo has a 24 pin connector.

I have an old Enermax 460 watt power supply with a 20 pin cable. I've had this Mobo since summer when conroe came out and the AMD x2 prices dropped like crazy. I have not had any trouble with my system.

That being said, I am not necessarily recommending that you do the same.
I'm just saying that in my case, it's worked out OK.

Ok, seems like there is no harm in trying. Thats what ill do. Its not a super power hungry sytem i am building (7800 GTX, 3700+, 2gb, 2hd's).

Actually I work at best buy for their geek squad and have seem some stock systems that use 20pin PSU on a 24pinsocket mobo (they left 4 pinsockets empty; no adapter or nething)...i thought it quite strange that a manufacturer would risk such instability? I suppose it comes down to the almighty dollar

oh goody, they got rid of the 24,000 views 20-24 pin sticky topic, so now we can redo the whole thing over the next 6-12 months

How about a sticky with basic information, like 20-24pin etc...

One more question: i have a molex connection on my motherboard, what do i need that for?

The 4-pin I assume? 12V "p4" connector, more juice to the CPU bascially

I believe he is talking about the 4x1 molex connector, like on hard drive and optical drives. Some motherboards have this type of connection in case the power supply doesn't have a 2x2 type connector, or even they are used in addition to it.

The 12V connector is used for the CPU.

The molex connector is used for the PCI-E slot(s).

I wonder how long it is until we have dual 8-pin connectors to the mobo? Or even dual 24-pin connectors...

The motherboard is an asus a8n SLI deluxe. I just checked the motherboard manual and i believe it is for sli use. In any case it said that the red light on the mobo would light up if there were two pci-express cards connected and the molex connecter was not. I also read in a german magazine that the molex is not nessecary.
