4 pin psu cpu cable

[leonardmartin29]

ok so i bought a new psu today a hx850i noticed that on my motherboard it has a 8 pin and a 4 pin for cpu power motherboard is a asus tuf z490 plus wifi but no cables that come with it is a 4 pin connector where do i buy it what is it called

you dont need to worry about the 4 pin. Thats only needed if you're going to go extreme overclocking on LN2 basically. For everyday use, you wont pull enough power to saturate the single 8 pin which can push around 350watts.

Your PSU comes with two cables that should be labeled either "CPU" or "EPS". and have 8 pins on one side (and maybe 8 pins on the other side too, not sure)

One of these cables (or maybe both) can split apart into two 4 pin connectors.

 

One of the cables, leaver together and plug into the 8 pin of the motherboard, the other cable split it apart and plug it into the 4 pin of the motherboard.

 

Although the 4 pin EPS connector is not needed for most normal applications.

thank you so much i didnt notice one comes apart

What would be the purpose exactly?

mmmk, well your PSU comes with 2 CPU/EPS 12v cables, they should be in a 4+4 connection on each. Use 1 for the 8 pin and the other only use 4 of the 8 pins and tuck the other 4 away as neatly as possible.

Let's not pretend that "I wanna" is not a good enough reason. I got double 8-pins connected myself, on a cpu that doesn't really go beyond 150W with my too-lazy-to-properly-OC butt. I just like plugging things in I guess ¯\_(ツ)_/¯

excatly i just like things plugged in.

Ok.  Well... make sure you populate all of your PCIe, M.2 and SATA ports as well.

It is actually better to have both EPS power connections plugged in if the MB has them.

 

If one has enough PSU in the 1st place to have more than one EPS cable there is no reason to not plug them both in.

my psu has more than one eps power connection i just didnt realize that the cables split from 8 pin to dual 4 pin

but i would have no where to plug the other side in so that would be useless

If you don't need them, then there's no use, and I doubt you can substantiate it with actual data that would actually affect most users. You can argue that the individual wires might be at a lower temperature when you have it split across two connectors, but that's making the assumption the motherboard is even configured to do that in the first place, rather than just using one connector until its power capabilities are at their limit and then utilizing the other connector.

That's all a total bunch of BS.

 

Created by the very same ones to cater to those who under recommend PSU wattage.

 

Or are too cheap to actually buy a PSU that is actually needed to the system in the 1st place.

 

There has been a lot of coddling going on with this for too long and it's a total bunch of crap.

 

2x EPS connections means a 750W PSU as very few 650W PSU come with 2x EPS cables.

 

The MB designers wouldn't have put 2x EPS connections on the MB in the 1st place if they weren't needed.

 

They aren't just there for looks.

Where did I claim they were just for looks? I mean, I asked for actual substantiation of your claim, but got none. Just backlash. 

 

My claim is that most users will never need to utilize the 4 pin connector in conjunction with the 8 pin, which is absolutely correct. 

 

Instead of properly responding to me with actual data, you compare me to users who use absolute trash in their machines or recommend users to buy garbage or do things that are hazardous or straight up dangerous.

well seeing as the question has been answered i dont think we need to continue to have this convo. I will use both 4 pin and a 8 pin. if you dont wanna use it then dont thats your choice

You personally asked MOST users?

 

In the world, that's Billions of people.

 

Must have taken some time.....

 

So unless you, or others actually designed the MB's in question then well..... You get the idea..

 

A car will run too if you unplug a couple of spark plug wires, but it won't run as well as if they are all plugged in.

It's included for people who actually find a proper use for it. Most configurations won't need it. 

 

You can't give a proper reason why a user would find it useful that isn't what I stated earlier.  

 

Your statement is basically "if motherboard manufacturers didn't think users would need them, they wouldn't include it". They included it for users who need the extra headroom. I reckon that most people don't.

Like most people don't need all 6 or 8 spark plugs in their cars right.

 

They will run without them all plugged in so why bother?

 

Just unplug a few and or take them out because everyone doesn't need them.

 

That is the exact same logic...

 

And yes a car will still run in case you doubt it.

 

The only real mistake the MB makers made was they didn't add actual detection for the EPS connections like some GPU makers have for the PCIe connections.

 

In other words if both the power connections aren't plugged in the MB wouldn't fire up.

 

They do need to add that to stop a lot of the BS and there would be zero question one way or the other.
