connecting a 24-pin PSU to a 20-pin MSI K8N NEO2 PLATINUM

[dazedniteman]

Well as you can tell from the subject the MSI K8N NEO2 PLATINUM that I just bought from newegg has only a 20-pin connector while the PSU that came with the case I bought (Thermaltake XASER III LanFire VM2420AU Silver Aluminum/Plastic ATX Mid Tower Computer Case 420W Power Supply) has a 24-pin connector coming out from it. Am I able to connect the 24-pin PSU to the 20-pin Motherboard without any problems? I currently have it set in there but have not attempted to boot it up until I know that there will be no problem.

I also have a question but kinda off the motherboard issue, but the power supply has TONS of wires coming from it and I have no idea what to connect them all to! This is my first computer I am building so is there any guide available for helping me connect the PSU to all the components and what goes where? I already put the motherboard in the case, CPU and heatsink are attached to the mobo and ram is installed. Video card, sound card, hard drive, dvd burner, and cdrw are left to be installed. Also, the DVD burner is OEM so what will I need to buy or get to hook it up to the motherboard. Same with the Hard Drive. What is needed to hook it up?

Thanks everybody and yes, I did search for about 20 minutes and didn't see any 24-pin PSU to 20-pin mobo but I saw tons of 20-pin psu to 24-pin mobo.

Yeah, here ya go and the Data & Power Cables and Final Connections pages should help here.

If your PSU's main 24-pin cable has a detachable 4-pin piece like shown in this photo, that would solve your issue. Otherwise, if you can get the correct 20 pins into the mobo without the extra four hitting anything, that would be fine from an electrical standpoint. Looking at a closeup of your mobo's power connector area, it looks like there's room to do that if necessary.

The correct 20 pins to plug into the mobo can be discerned by looking at my photo of the 24-pin one and noting the colors of the wires going into the extra four pins. Find that part of your own cable and make sure it's the part that's hanging out in open air, rather than plugged in.
