IEatHardDrives Posted August 19, 2005 Report Share Posted August 19, 2005 Ok im getting a MSI K8N Neo4-F Socket 939 NVIDIA nForce4 ATX AMD Motherboard and it has a 24 Pin connector and the PSU has only a 20 Pin connection does the motherboard need the other 4 Pins?

Each PCIe x16 slot is designed to deliver up to 5.5A @12V. And another signifigant amount (about 3.5A) @ 3.3V.The added pins are designed to share that increased load (partiuclarly the load at 12V as a 20 pin connector has only a signle 12V return line).General rule:low power system, no problem.decent gaming machine, should be ok with a good PSU.Top of the line, high speed, high power desktop, you're spending some major cash already, do it right and buy the correct PSU.

IEatHardDrives Posted August 19, 2005 Author Report Share Posted August 19, 2005 Im going to get a 20 pin to 24 pin converter. Quote Link to post Share on other sites
Freidog Posted August 19, 2005 Report Share Posted August 19, 2005 Im going to get a 20 pin to 24 pin converter.<{POST_SNAPBACK}>bad idea.You gain nothing.And it adds more resitance (however small) to the line (makes things worse).Plug in the 20 pin connector as is or buy a PSU that supports the 24 pin connector natively.

IEatHardDrives Posted August 19, 2005 Author Report Share Posted August 19, 2005 Ok I think this psu supports a 24 motherboard it has the 20pin connection then it has 4 extra plugpic Quote Link to post Share on other sites

That's to supply power for a P4 processor. Quote Link to post Share on other sites

That's to supply power for a P4 processor.<{POST_SNAPBACK}>...and plugging it into a 24-pin ATX connector is a Very Bad Idea. Just to be absolutely clear.FWIW, it's used by processors other than the P4, including Athlon 64s and some Athlon XP motherboards. Quote Link to post Share on other sites

Pete_C Posted August 20, 2005 Report Share Posted August 20, 2005 The best advice I can give you is to get the correct powersupply for your motherboard. Although most of these are keyed so that you can put a 20 pin in only one way, I have heard of people doing this and the motherboard smoking and dieing and taking everything with it when they power up.http://www.msicomputer.com/product/p_spec....Neo4-F&class=mbNormally , other than some Compaqs, this 24 pin is for PCI express boards.By not using the correct power supply , or at least an adapter designed to meet the requirements, you are going to over draw current on some of the 20 traces which are connected and risk burning something out.

xxkbxx Posted August 20, 2005 Report Share Posted August 20, 2005 Yeah, just get a PSU that supports your 20/24 pin and/or P4 connector needs Quote Link to post Share on other sites
