All Conroe E6xxx series REQUIRE EPS 12V?

[nanikore]

I searched the forums with "conroe eps" and did not get the info I was looking for so here goes.

Do all Core 2 Duo E6xxx series CPUs require EPS 12V power supplies (8pin instead of 4pin on 12V connection)?

My E6700 system shows 11.8V on +12V rail.

I only have a regular ATX 2.0 suppy right now. System is working fine but I don't want to take any risks. If I have to shell out to replace the supply I guess I'll have to. :-/

:welcome: to the forums!

Whether or not an EPS power supply would be required would be determined by the motherboard, not the processor.

Most 965 chipset motherboards use the 4-pin connector. 975 chipset Motherboards by Asus, Abit and MSI all use the 4-pin connector, while a few, like the Intel BOXD975XBX2KR use the 8-pin EPS connector.

Use a multimeter to check your voltage. If you're showing droopy 12V rails and/or your system is unstable, get a more robust (not necessarily an EPS) PSU.

BTW, some system specs would help us to help you; either in your signature or in your post. Specifically for this thread: motherboard make/model, PSU make/model.

Thanks for the welcome :D

The board is Foxconn P9657AA-8KS2H (http://www.foxconnchannel.com/product/motherboard_detail.aspx?ID=en-us0000171), which is a P965 board that somehow comes with a 8pin connection. It confused me at first but I just plugged the 4pin into half of the socket. The power supply is Ultra V-series 500W (http://www.ultraproducts.com/product_details.php?cPath=59&pPath=369&productID=369).

CPU: Core 2 Duo E6700
GPU: Sapphire Radeon X1900GT

System is stable, but everything is on stock speed. I want to be sure before I do any kind of OC (not the extreme kind that everyone else here probably does, just moderate). I don't own a multimeter right now.

well, its going to be suggested so i might as well say it now.






get rid of that PSU now. before it blows up taking your computer with it. that psu isn't the greatest in the world, if i were you, before i did any overclocking was to get a better powersuply. and having a 4pin in an 8pin probably isn't helping.

Hi ya
If you keep your PSU then I would use a 4-Pin to 8-Pin ATX Adapter Cable that may stop some of you drop
All so read this sticky (http://www.ocforums.com/showthread.php?t=458204) it will help you alot on what to look for in a good PSU

And :welcome:

[Jacobman]

Welcome! Even if its working now with the 4/8 pin connection it may not for much longer. Also the PSU is typically the most under looked component in PC's so make sure you get a nice one.

You're right. Ultras generally aren't good.

After I saw this article (http://www.playtool.com/pages/psuconnectors/connectors.html#4into8)though... I'm definitely will be switching to EPS 12V. I don't want something to MELT. I wish that MB/processor manufacturers would somehow make a bigger deal out of this issue by putting something in the manuals (e.g. "GET EPS 12V OR THINGS COULD MELT"). :p

Nothings gunna melt unless you put your motherboard in the oven or grill :clap:

I built a system for a friend that I didnt use the EPS 12v, it had it, but i didnt use it
He had a C2D setup with an ASUS 965 Chipset board

Worked fine, and still is working

there is no big deal about using a none esp psu on c2d cpu's/mobo's. i ran my c2d system for some time before noticing my mobo had a 8pin connector. since the powerstream has this eps connector i did use it. i did not notice any stability problems with out it or any problems with ocing at all. there was also no difference with it plugged in.

Interesting. Maybe I should just try running Prime98 and measure the supply with a meter.

I was thinking that description was a bit extreme......

Maybe it was talking about server power supplies or something, and not the little weakling in the back of my box.

Im currious of the OEM of that particular line of Ultra PSU's

Could you do me a favor?

Could you look on the sticker on the power supply and get the UL number off it (under the symbol that looks a bit like a backward R with U right up against it) on this site and search for the results?

I'll do that when I get home.

In the meantime this is an article that I have seen before about someone's meter measurements on the supplies, just in case someone else is curious:

ew even i wouldnt use a V-series.. and i own an Ultra X-finity PSU.. They are not the best but this psu has never had a problem and never drooped below 12.09v

OEM is probably CWT. Not a fatally flawed unit but I would be a bit conservative on the overclock.

Hello again. The number under the backward R with U is "E178768".

The search that greenmaji referred me to showed a Canadian company called Wintech.

Yeah, I'm not going to go for big overclock. Even if I want to, this motherboard does not overclock very much anyhow. I don't remember the number, but it was only around 350mhz FSB. As for practical use, even before I switched from E6300 to E6700 I was getting good framerates in Oblivion with nothing overclocked. Maybe things will change when the next batch of machine-choking games come along...
