Isn't it going to be a horrible idea to daisy chain power like this?

Isn't it going to be a horrible idea to daisy chain power like this?

No, why would it be?

Naw those are ok.

But I can show you a nuke.

I don't know if "horrible" is applicable but that could get ugly if any of the wires are poorly joined to that first socket

because all the power from the second card is passing through the first's port?

Or are they like 2 separate sets of cables inside the sleeve?

That isn't how it works, user. Lots of PSUs have cables like this. Nothing is being passed through anything. It's fine.

from > Sup Forums is NOT your personal tech support team or personal consumer review site.

What in the holy fuck are you on about?

The leads are terminated into the Molex connector together. The power does not travel through the whole card and out to the next, you fucking faggot. As long as the PSU is qualified to run both there is no problem. But then again this is Linus... who the fuck knows. fuck you all goddammit

do you not know how to read, kid?

Uh he's asking fair question go jack off to your lolis and gnu/linux faggot

Crying tech support about everything you don't like is a new meme.

I always thought the reason they split power cables like this was because a lot of cards don't utilize the full power available with two pcie connectors.

So, yes, since he is using them on seperate cards, and we are talking about ~300 watts through that one cable, it seems like a bad idea.

oh wait, i forgot about motherboard power. so more like 150 watts. Still a lot.

Does Linus still work for NCIX?

I think he still shows up in the occasional video

That's a really nice electric griddle you got there.

No he doesn't thou he does have a deal with them to show up in videos from time to time, they allow him to film in their stores and sometimes they give him things that he can't just get with his reviewer status

All PSU PCI-E power cables use the same rail

so in the end it doesnt matter

But it's just not right man

Hur dur what is amprage vs voltage?? Hurr....

That aint a daisychain. There are separate wires for each 8pin. And it all comes from the same 12v rail.

You probably should get a basic understanding of how electricity and electronics works before you ask dumb things.

GPUs and CPUs do not give a shit about signal pollution in the power source. They get smoothed. The ICs operate in a voltage range and output in binary. It is literally impossible for them to do anything wrong as long as the power source stays within that voltage range.

Audio equipment is different. Voltage will significantly (?) affect the result of the output analog signal because the analog components are sensitive to voltage changes.

Also this guy is right. The GPUs are connected in parallel to the PSU's 12V (mostly) and 5V rail.

They're in parallel, so the only signal pollution comes directly from the PSU, and there is no voltage drop.

DO YOU THINK THEY WOULD PUT THE SECOND CONNECTOR ON THE FUCKING CABLE IF IT WAS A HORRIBLE IDEA?

but it's meant to be used on a single GPU

>because all the power from the second card is passing through the first's port?

If that was the case then those cables would not work on a single card with 2 power connectors either.

>meant to
Once again, basic electricity and electronics.

Seasonic will recommend that you use a separate PCIe 6/8-pin power cable for a separate graphics card because it has access to a second 12V rail (if it exists).

If you look at your PSUs technical spec, you will see the maximum amperage (or watt rating) for the 12V rail(s).
If the power draw on the single cable exceeds the amount specified for the rail, then you need a second cable to access the second rail.
If you cannot in any combination of cables deliver the power required by your card, then you need a better PSU.

For reference, a 6 pin PCIe power cable draws a maximum theoretical 75W. An 8-pin PCIe power cable draws a maximum theoretical 150W.

Well ya, it doesn't matter with a single rail, but it's still an odd practice

In other words, there is literally nothing wrong with using a single 6/8pin PCIe power cable to connect to multiple GPUs as long as the 12V rail is sufficient to deliver the power.

What is the fucking difference? jesus christ,

lmao im not OP but this is the simplest answer that makes sense w/o having to understanding currents and electricity

Look up Parallel Circuit. That's what this is.

This is the same as when someone says >>>Sup Forums

I bet these are the same people that start desktop/homescreen/battlestation threads every 30 seconds.

There are some serious retards in this thread. Confirmed most of Sup Forums only knows how to plug things together with no idea how or why any of it works.

>Y'all

when are white people going to stop talking like black people?

Ya'll is like a southern thing man

Electricity doesn't get "used up" like fuel does. It goes in, it effects a change, it goes somewhere else. Put in more than the card will use and it will flow to another card if it is plugged in.

Y'all come back now, y'hear?

This.

This is a question about basic circuits, stuff you should have leaned in 6th grade science class.

I do this with my 660 sli rig, it's fine faggot.
