if my mobo has a 24 pin slot and my psu only has a 20 pin connector, do i need to go get a new psu or will it still run?

It really depends on the motherboard. Most of the time you can get away with using an adaptor.

Oh..hmm the nforce 4 chipset. Eh..what size supply do you have now?

You really should get a proper power supply.

The only time I would even consider sticking with your current one is if it's pretty good to start (500W, 25+ amps on the 12V rail) and if you can't afford a new one.


I don't read the MSI forums, but you basically forfeit any help on the DFI ones if you use a 20 pin power supply, as they've been found to cause numerous problems, including ram death, no overclocking potential, and pci express problems.

One thing I should mention is that you should, at the bare minimum, have a 400watt power supply if you are thinking of using a 20pin to 24pin adapter. The reason is that the adapters work by splitting one connector into 2 connectors (they do this, of course, with 4 of them). The adapters work, but again, it is recommend that you should have at least a 400watt PSU to compensate for the extra power drain on those rails. Best option though is to get a new PSU that was made for with the 24pin header in mind. If you don't you could run into stability problems.

I just wanted to share that I had the same issue with my psu and motherboard. I just recently purchased an Aspire X-Navigator case with an Asus A8N-SLI Deluxe motherboard. When I got the case I realized that it only had a 20 pin psu not a 24 pin... but the reason I got that case was because it came w/ a 500w psu... I know not the greatest one but it fit my price range and I wanted a decent case. I contacted Aspire and they sent me an adaptor for free, but my motherboard came before the adapter and I wanted to get my computer up and running so I called Asus and they said that u didn't need the adaptor, you could just plug in the 20 pin psu to the motherboard and it would be fine. So far I haven't had any issues. I'm not sure if this will help you at all, but I agree that if u can you should get a psu with 24 pins. if not, then at least go for a good 20 pin psu. Also if you aren't sure contact MSI.

I should mention that some boards work fine with the standard 20pin, but there are some boards, especially the cheap ones (ie. ones that use cheap capacitors) that don't run at all. As I said it is recommended that you use at least a 400watt PSU, and the same goes for using just the 20pin header. Intels branded boards are fine, and assoloz2 just mentioned at least that particular Asus board works too. In my opinion though, I would buy a true ATX2.0 24pin PSU as they are designed for that use.

Right now the extra 4 pins are really not being used. The main reason they are there is for support later on when Intel needs it, either for stabiliy reasons, or faster processor that requires more power such as the dual cored ones.
