do i need to use the ez plug on my setup?

hey guys i apologize ahead of time if this is in the manual or in this forum somewhere. i have tried the search function
and google with little definitive answer.

i have a mfv with 3770k at 4.3, 16gb of 2133 ram, sli'd 670's factory overclocked and self overclocked, and also am running a sound blaster z. just wondering if im in need of plugging in the ez connector for power to the pcie slots. would it help make my oc's more stable/higher? any benefit at all?

i have noticed rare driver crashes and occasional volatge resets in evga precision x but i know that could just be from my current oc being to high on my gpus. would the additional power stable this out?

im currently running off of a corsair 860i with the 24 and 8 pin plugged into the board.

thanks!

LOL, I'm following a simple rule... - populate ALL power connectors on the mobo... :cool:

It won't be more power draw then the necessary, but the draw will be more balanced across the connectors... definitely won't hurt anything...

i have seen this theory all over the net while doing some searching. i cant say i disagree in any way, but its more of an opinion then anything else. i would like to see some actual guidelines on when the plug is 100% necessary and what kind of issue can be ran into or fixed by not using or using the plug.

plus filling all power connectors is not always possible (i can not fill the additional 4 pin cpu power plug with my current psi). just an example

OK, let me try in more detail... 🙂 You have the Asus Maximus V Formula, right?

That board has in total 4 power connectors:
1. 24-pin EATXPWR on the right edge, near the DIMM slots - it's a must to connect these one, no matter what... it's the main power supply connector to the mobo...
2. 8-pin EATX12V_1 - it is also required to connect, supplies power to the CPU
3. 4-pin EATX12V_2 - additional power supply to the CPU... When to use it? There is no specific rule for it, but in general it's suggested when the CPU requires more power - usually when you're OC'ing... As I said before, more connectors means more balanced power draw... the same amount of juice is drawn anyway, just through more connectors - gives you extra safety...
4. 4-pin EZ_Plug - is additional power to the PCIe lanes, most often graphics cards... in the manual says to use it when "two or more high end PCIe 16X cards"...

Now, what happens when you don't have enough power/you haven't connected all necessary power connectors?
With the first two, the 24-pin and the 8-pin it's clear... - your system won't start...
If you don't connect the 4-pin CPU power, but you start OC'ing, then you may experience instability of your system, it may not even boot if the voltage is set too high... in extreme conditions (voltages) you may overheat the 8-pin connector, which may cause terrible things...
With the EZ_Plug not connected, your SLI/CF setup may became unstable, resulting in graphics crashing... this also happens when you start OC'ing...

In case your PSU doesn't have all the necessary connectors, you always can get some extension/converting cables...

thanks zka for the detail. the last paragraph was what i was really looking for. this has helped me and will probably help others searching for answers with this question!

im def gonna try it! i work 24 hrs so im getting home this am and will start the process. its going to require me to disassemble first due to the tight fit of my build. ill post back with what i find. hoping this alows me to keep my current clocks with added stability!

thanks guys!

well 4 pin molex and 4 pin cpu plugs are in. the molex connector is a bitch to get to. the mixture of a down facing molex and the height of my psu made me have to trim part of the plastic away from the molex and wrap each wire with electrical tape to prevent any contact where the plastic used to protect. basically created my own low profile molex. doing this is the only way to fit the psu in without snapping off the connection, but i can see that there is still some stress applied to the connector (any issue with doing this??)

everything powers up nicely and no issues so far. using corsair link i did notice that with my over clocks applied im using over 100 additional watts compared to stock at full stress test load. plugging the additional connections in has to help distribute that nicer i would imagine.

i have not lowered my clocks so now its time to see if my occasional crashes persist. only time will tell thanks everyone for your help!

This thread has got me all fired up about the 4-pin EZ plug for the PCIe lanes.
jsarver, I also have the clearance dilemna, so I never bothered installing it.
However, I did locate two different right angle 4-pin molex cable extensions on the web.
Being the sucker than I am, I bought both and should have them by early next week.

link? i found true low profile molex connectors at frozencpu.com and they are only 99 cents but they arent right angle. the other issue and what is causing most of the stress on the connection is the fact that there is no room between motherboard mounting wall of case and the psu for the wires to tuck behind. i have to pretty much smash the wires between to two for the psu mounting holes to line up which is causing the plug to flex.

not a fan of the "ez plug" placement/orientation at all. its not very ez

Jsarver thanks for the tip on where to buy the 90 degree angle 4 pin molex extention. Just ordered it for my XI APEX. 🙂

Everything overclocked and love it.
ROG Awesomeness !!!!

I can’t believe after all this time and all these complaints they STILL use an angled plug!

Zenith II Extreme in a Define R6. *I doubt I’ll even be able to use the angled adapter but I’ll give it a shot. I’m hoping this is my issue. *AMD 3970x, 1600 watt PSU, only two 2080 Supers but they each have 8 pin connectors. *Anyway, my issue for some reason is I can’t enable SLI. *I’ve tried everything on the net except connecting that plug.
