fix-this! Posted June 30, 2008 Share Posted June 30, 2008 i bought a new motherboard and it says it has an 8pin cpu power connector slot on the board. my power supply only has a 4pin connector. ive read online i can use either an 8 or 4 with the new board. is this true ? i just want to make sure i won't need an adapter. whats the difference between the 4 and 8 pin, i assume more power to the board ? thanks in advance !!!

utdarkviper Posted June 30, 2008 Share Posted June 30, 2008 If you don't mind please post your PSU and system specs, just to make sure all else is well :) If it is a simple problem, then only a 4pin to 8pin adapter will be needed, but it would be best to make sure the PSU works with everything else well.

MR_Candyman Posted June 30, 2008 Share Posted June 30, 2008 my newest board has an 8/4 as well. There was a plastic tab covering the 4 that you don't need. I'm not really sure why they are adding the other 4 at all. I have yet to see an unstable system with the 4 pin Link to comment https://www.neowin.net/forum/topic/646231-8-pin-cpu-power-connector/#findComment-589520294 Share on other sites More sharing options...

I have yet to see an unstable system with the 4 pin yeah ive read online that you really don't need the 8pin unless your extreme overclocking the cpu. i just wanted to make sure is all. i also used the wattage calculator on neowin and my system only requires under 400w and i have a 500w psu.

A month old when you got it but dam is it an old model like over 2 years old! You never know it could turn out to be your PSU cause the problem.

utdarkviper Posted June 30, 2008 Share Posted June 30, 2008 I don't now how great that PSU is. I understand you already bought it, but hopefully it will hold up to overclocking. 4 pin to 8 pin adapters are available, but I don't know anything about just plugging the 4pin in to one side. I would research that online. adapter http://store.pchcables.com/atx4pinto8pi.html EDIT: @PeterUK: It's still being sold on newegg.com :p http://www.newegg.com/Product/Product.aspx...Tpk=RP-500-PCAR Link to comment https://www.neowin.net/forum/topic/646231-8-pin-cpu-power-connector/#findComment-589520313 Share on other sites More sharing options...

fix-this! Posted June 30, 2008 Author Share Posted June 30, 2008 well i went ahead and ordered an 4 to 8 pin power converter / adapter for the new board. should all be here by tomorrow. i had a total of 5 bsod's between last night and this morning. i again ran memtest86 all night with no erros. i ran wd data lifeguard diagnostics on both my hdd's with no errors. i ran priume95 for 8 hours on Saturday for my cpu with no errors or bsod. i did a boot time scan of my pc with antivir and kaspersky with no viruses detected. i checked my voltages in by bios and everything is ok: vcore = 1.332v ddr2 = 1.872v + 3.3v = 3.376v + 12v = 12.492v i also did a voltage calculator for my 500 psu and i have plenty enough power. the bsod's were all different and pointing to different errors. i spoke to a pc tech today over the phone and he said more than likely it my intel northbridge chipset dying or overheating. so the new board should fix this problem. my gpu and cpu temps are very good too, so i know there not over heating. i am running at stock speeds too. i plan on contacting gigabyte today to see if i can send the defective board back for a replacement. then ill sell it online. :p Link to comment https://www.neowin.net/forum/topic/646231-8-pin-cpu-power-connector/#findComment-589521999 Share on other sites More sharing options...
gummyz Posted June 30, 2008 Share Posted June 30, 2008 I had driver issues causing BSOD on Vista myself, so this could be driver/software related. On topic: I have run 2 PCs with 4-pin, while the motherboard had 8-pin. Both computers have worked fine, and one ran for a good year and never experienced any issues myself that were related to the 8-pin needed. I don't overclock either and yes, most of the time, the 8-pin is used for overclockers or quad cores. I also bought myself a 4-pin molex to 8-pin just in case. It is still sealed and sitting in the original package :) Good luck.

CrashG Posted July 1, 2008 Share Posted July 1, 2008 I'm running the machine in my sig with just one 4 pin PSU plug (although I have another 4 pin plug on the mobo and PSU) to make it a 8 pin, no problems OC'ing. I've heard that it's useful when using a quad core, but I don't have any first-hand knowledge of that.

fix-this! Posted July 1, 2008 Author Share Posted July 1, 2008 well im still waiting on my converter to ship out from newegg. there dragging there heals and im getting upset since i paid for rush processing. anyways i was on the official DFI boards and some of those guys are trying to tell me i need to buy a new psu with the 8pin power plug. its really peeing me off to because the mobo manual clearly states if you don't have the 8pin you can use the 4pin. that's why i bought the converter plug the first place to play it safe. im not planning on overclocking very much if any at all. the 8pin from what i read just gives the cpu extra power when "extreme overclocking" which im not going to do anyways. there very rude on that forum too. see for yourself's : Link to comment https://www.neowin.net/forum/topic/646231-8-pin-cpu-power-connector/#findComment-589525308 Share on other sites More sharing options...
+PeterUK MVC Posted July 1, 2008 MVC Share Posted July 1, 2008 I don't know why you don't just start using your new motherboard with the the 4 pin now. Note: the manual dose not show where to connect the 4 pin into the 8pin connector but its the top half of pins 4 & 8. All the adapter will do is give extra routes for the power to go through.

gummyz Posted July 1, 2008 Share Posted July 1, 2008 They said the same about my DFI Lanparty NF4 Expert, although I ran it fine without it.

bigmehdi Posted July 2, 2008 Share Posted July 2, 2008 (edited) well my psu (an antec quatro ) have both connections : 4pins & 8 pins. And my motherboard, allow both (ga-x48-dq6). If I want 4 pin, there's a cach that prevent errors (must connect right pins). Otherwise, I just remove the cach & use 8 pins. I didn't notice any difference between 4 pin & 8 pin. According to everest, I have 12.52 v for the 12v input (under ATX specifications, but annoying I think). Also, according to my manual , 8 pins are recommended for the core extreme series. But seems to work fine on regular cpu. If I don't need an adapter for my motherboard, then should be same for yours. But it's important to use the right pins or it might be catastrophic. Fortunately, the manual of my motherboard is well documented.
