I just purchased a new 4070 Super. It comes with the new style power connector on the GPU itself. However, I have a last gen PSU. The good news is the GPU comes with a splitter that will allow me to plug the 4070 into my old SFF 650 PSU (see image attached). The PSU has two 6 + 2 power connectors that are intended to run to a GPU (see other image attached). My understanding is that, it is best practise to have two separate cables plugged in to the PSU, and then to each end of the splitter - That's fine. I'm actually having difficulty locating such a cable in the UK though.

I looked on Amazon and there is a 6 +2 pin to 8 pin, male to male connector. However, the 6 +2 end is marked end is marked as "PCIE". The other end which is strictly 8 pin is marked "PSU" on most wires. I need the PSU end to be 6 +2, and the GPU end to be one solid 8 pin.

If you look at that image you can see the end that plugs into the GPU is male. The other end (which is split into 2) looks to be female.

#

On my PSU it is female. So my thinking was I would need a male to male cable

hybrid lotus
#

Yeah? How would you be able to plug in a male from your psu?

#

Huh?

#

Your psu modular cable should be male male

median spoke
#

I would plug the male in to my PSU as normal. Then plug the other end, also male, into each end of the splitter.

hybrid lotus
#

Yes

royal storm
#

There’s no issue here

median spoke
#

I have no PSU modular cable. You are confusing me here.

hybrid lotus
#

The left image is a modular psu, those are modular cables

royal storm
#

Your solid end goes into the psu

#

The end that splits goes to the adapter

median spoke
#

The image does appear to be female on the split ends. Is that incorrect?

royal storm
#

Plug the stuff in you’re overthinking

#

Solid end to power supply 6+2 to gpu

hybrid lotus
#

All psus are female we are talking about your cables

median spoke
#

If you look at the cable that comes with the new 4070 Super the end that inserts into the GPU is visiblly male. The other end looks like ti could be two female ends.

royal storm
#

It’s not at your house

hybrid lotus
median spoke
#

I question if they will plug into the PSu at all since both ends appear to be female. Length isn't a question I've rasied.

royal storm
#

You’re speculating over nothing, all will be fine. Put this as solved and enjoy your computer when that time comes.

median spoke
#

I'm specualting because I do not know.

hybrid lotus
#

Please read your GPU manual if you read it, you wouldn't have posted this

median spoke
#

Does someone know?

royal storm
#

He doesn’t have the gpu in hand yet

median spoke
#

Are the ends on the splitter male?

hybrid lotus
#

Oh

median spoke
#

I just ordered the GPU. I do not have it yet.

hybrid lotus
#

I understand now

median spoke
#

The images look like the two splitter ends are female.

hybrid lotus
#

To make it really simple psu > male to male cable > GPU splitter (right image) > into gpu

median spoke
#

So I would need a male to male cable. I had guessed that for myself. However, on the PSU it says 6 + 2. I'm assuming the other end would be 8 pin male.

#

I've looked for these cables on Amazon but most say the 6 +2 end is for PCIE

hybrid lotus
#

6+2 = 8 not sure how you don't get that

royal storm
#

So do you not have any cables for the psu

hybrid lotus
#

That's how those extra 2 work

median spoke
#

So a male to male cable can plug in either way? It doens't matter which end goes into the GPU, and which end goes into the splitter?

royal storm
#

Or do you need extras

#

As I said earlier

#

The split end goes to the gpu

#

The solid end goes to the psu

median spoke
#

Yes, I need extra cables. I'm going to order them once I know which ones I need.

#

So the split end is a male?

royal storm
median spoke
#

I can plug the two splitter ends direcly into the GPU?

#

If the two ends on the splitter are male I can plug them into the PSU no problem. However, they certainly look female on that image posted.

#

I thought I would need an 8 pin to 8 pin, male to male connector. A 6+2 male end to plug into PSU, and a 8 pin male to plug into the GPU. 2 separate cables.

royal storm
#

Get the gpu first then we will all come back and have a laugh

#

Good day to you

median spoke
#

If someone can just tell me that would be great.

#

Is the joke that the splitter is male and plugs directly into the PSU?

#

It takes two seconds to just say that

hybrid lotus
#

Either totally clueless or huge troll. We told you the answer multiple times now

median spoke
#

Where was that said please?

#

I have asked but no clear answer was given.

hybrid lotus
median spoke
#

If the two splitter ends are male, and plug directly into the PSU then fine. Nobody has said that.

#

Is there anywhere else I can get some help with this issue? If I need cables I'd like to order them today so I can have them ready when the GPU arrives.

#

When you look at this image the end that plugs into the GPU is male. It's clear as day. The other two ends look female. No way to be sure looking at that image alone.

ScreenHunter_245.jpg
#

My assumption is that both ends were female. And that I would need an 8 pin to 8 pin connector to plug each end of the splitter into my PSU.

#

If the two ends on the splitter are male, and go straight into the PSU then I'm fine with that. But cannot find a clear answer.

#

Is there anywhere else on the forum to get some help? There must be a clear and easy answer to this. I've never dealt with one of these more modern GPUs before, or these adaptor wires. It's difficult to find more detailed information on the wire itself.

hybrid lotus
median spoke
#

I already told you my guess was that it was female. The connectors on my PSU are also female. So I would need two cables, both that have 8 pin males on either end.

#

Would 2 of these do the job?

ScreenHunter_245_01.jpg
#

I can run that from the PSU, to the GPU splitter. I would buy 2 of them.

abstract relic
#

and they're wildly different from psu to psu

median spoke
#

It does say that both ends are NOT interchangable.

#

So I would need a 6+2 that plgs into the PSU, and an 8 pin that plus into the splitter.

abstract relic
#

the fuck are you talking about

royal storm
#

What in the hell are you talking about

abstract relic
#

you need a cable that is specific to your power supply

royal storm
#

I’ve said multiple times the split end goes to your gpu, the solid end goes to your psu

#

6+2 is a split end

median spoke
abstract relic
hybrid lotus
#

Because it is

median spoke
#

If the splitter ends on the adaptor are female they will not plug directly into the PSU.

hybrid lotus
#

Of course not wtf

abstract relic
#

ofc not holy shit. the adapter is like 3 inches long

median spoke
#

I understand all of this too

hybrid lotus
royal storm
#

And multiple times

median spoke
#

So two wires are needed? Each cable needs to have one end male 6+2, and the other end 8 pin?

royal storm
#

This is just going to be a cycle

abstract relic
#

bottom line is, you need a cable that is specific to your psu. do you not have pcie power cables for your psu?

royal storm
#

And you can’t just throw random amazon cables in your psu

abstract relic
#

^^^^^^^

median spoke
abstract relic
#

what is your psu

median spoke
#

So, I do need to purchase a new wire. I'm just trying to make sure I get the right one

#

It's a Corsair SFF 650w PSU

abstract relic
#

what model

median spoke
#

Not sure TBH. I thought the Corsair SFF 650w PSUs were all the same.

royal storm
#

Check the sticker on it

abstract relic
median spoke
#

Hold on I'll open it up and have a look

abstract relic
#

do you have any pcie power cables plugged into it right now?

median spoke
#

That is the label on the PSU

PSU.jpeg
#

RPS0112

abstract relic
#

it looks like the sf600 uses corsair's type 4 cables

median spoke
#

Part number CP-9020182 / 75003563

#

In fact it is a 600w

#

It thought it was 650, my error.

abstract relic
median spoke
#

Right now there is no PCIE cables plugged in poweing a GPU. I have an RTX A2000 which is powere by the PCIE slot alone (75watts)

abstract relic
#

i see

median spoke
#

So I would need to order new cables.

#

My understanding is that it is best to have two separate cables. Each one running from the PSU, to the GPU splitter.

abstract relic
#

yes

#

can you take a picture of the connectors on the psu?

median spoke
#

Yes, one moment.

#

As you can see, there is two empty slots there. both are 6+2

abstract relic
#

Yeah. Though that’s referring to the other end of the cable. The psu end itself doesn’t split

median spoke
#

I dind't know that. I just assumed I would need to plug a 6+2 into the PSU itself.

abstract relic
#

Same with the “4+4”

median spoke
#

So, any idea what sort of cables I might need for this? I want to make sure I order the right thing. The last thing I want to do is blow a brand new £600 GPU.

abstract relic
#

Corsair type 4

#

Wait

#

Yeah type 3 or type 4 pcie

median spoke
#

Nice find

royal storm
#

You can get the cables straight from Corsair but they are always out of stock

median spoke
#

It seems part 4, 8-pin EPS12V cables are needed.

abstract relic
#

No

#

You have that one

#

You just need type 3 or 4 pcie

median spoke
#

How about these ones?

royal storm
#

Does the seller say Corsair

#

Probably

abstract relic
#

That is from Corsair

median spoke
#

£50 for 2 cables. Jeezo 😂

royal storm
#

Wait it won’t work

abstract relic
#

You’d only need 1 of those

abstract relic
royal storm
#

Oh nevermind

#

I looked at that all wrong

#

That’s just if you want to natively do it without the adapter

#

Even then you can just do without it

median spoke
#

Why only one? I thought I would need 2. Both running from PSU, to each end of the splitter.

abstract relic
median spoke
#

Really? And plugs straight into the GPU?

royal storm
#

Yup

abstract relic
#

This connector is the same one on the single end of the splitter

image0.jpg
median spoke
#

Oh, I see now. I thought becasue my PSU was last gen getting one of the new 12 pin connectors (I think that's right) wasn't possible.

#

This looks perfect

abstract relic
#

If you ever get a gpu without the 12+4 pin, you’ll need to replace it, but it’ll work for your current gpu just fine

median spoke
#

Thanks for your help with this. It's greatly appreciated.

#

My first time dealing with one of these new GPUs hence the confusion on my part

abstract relic
#

Ideally, you get a psu that has a native 12+4 connector, but this will work

#

Also there’s like 1 sff psu and it’s 1000w and pretty expensive

median spoke
#

I bought the Zotac 4070 Super. It's rated at 220 watts. So I should be able to power it with what I have.

abstract relic
#

Anywho, that cable will be fine for you now

median spoke
#

Can't afford to switch everything to next gen yet. This new GPU should give me many years of new life in an old PC
