Is the Corsair TX-M Series 650 & Sapphire AMD RADEON RX VEGA 56 compatible

[Xcel]

Hi all,

 

I'm a bit new to this and decided to try and build a computer (First time) using pcpartpicker and looking up some pre-existing builds.

My PSU has arrived which is a Corsair TX-M 650 

 

And the Graphics card I have bought is a Sapphire AMD RADEON RX VEGA 56 PULSE 8GB HBM2 Graphics Card.

 

Does this PSU work with the GPU?

The only reason I ask is that the GPU has 2 x 8 pin slots and the PSU has 1x 6+2 PCI-E & 4+4 CPU slot (please see photo attached). Now I'm unsure if I can just use the 4+4 CPU slot as another PCI-E slot for the GPU?

 

I've tried googling the answer and the only thing I have seen on this is not to daisy chain a vega 56.

Any help would be greatly appreciated. All the parts will arrive by Wednesday and I'm unsure if I've bought a PSU which is incompatible. 

 

Many thanks

yes it does. you could run the 550w variant no problem.

we could put something together if you just tell us what you are looking for and give us a budget and location.

Thank you. I've actually bought the components already. (May have jumped the gun but hopefully, it's okay).

What cables would I use to connect the GPU to the PSU? would I daisy chain it or would I use both the 6+2 PCI-E & the 4+4 CPU slots? Sorry if I'm being silly, just unsure how to wire the GPU up.

there are 2 6+2 pin ends on the PCIe connector. 

 

do not plug the 4+4 into anything other than the CPU power connectors.

Thank you! I guess I was just being a bit dense! I've looked up some guides to build the computer so hopefully, it'll go off without a hitch  But again thank you for the help!!! I should get all the components on Wednesday so ill give building this a go

@Xcel

 

The three 6pin slots on your PSU all accept both Peripheral and SATA cables.

 

The two 8pin slots on your PSU accept both PCI-e cables, and CPU cables as well.

You may understand the "6+2 PCI-E & 4+4 CPU" painted on the unit as "the top 8pin is for PCIE, and the bottom 8pin is for CPU", but what it actually means is both of those slots accept both types of cable.

 

TX650M already has one 4+4pin CPU cable permanently attached, so you'll use it to power the CPU.

TX650M has two modular PCI-E cables, each cable has two 6+2pin connectors at the end. So, you can take one modular PCI-E cable, and plug its 8pin end into any of the two 8pin slots on your PSU. Then take the other end with the two 6+2pin connectors, and plug them into the GPU.

 

For high-power graphics cards like vega, it is better to power them with two cables though.

So take one modular PCI-E cable, plug its 8pin end into one of the two 8pin slots on the PSU, and plug one of its 6+2pins on the other end into one of the 8pin slots on the GPU.

Then take the second modular PCI-E cable, plug its 8pin end into the other 8pin slot on the PSU, then plug one of its 6+2pin connectors into the remaining 8pin slots on the GPU.

 

I tried to be as verbose as possible to hopefully not leave you with any doubts.

 

 

GoldenLag seems to misunderstand what you're asking for, and thinks your PSU has separate plugs for CPU cables and for PCIE cables.

@ me if you have any issues. 

 

remember to click my name when you then @ me so that i actually get a message.

@OrionFOTL

 

Thank you for your reply.

So are you saying that for the vega 56 I should use the PCI-E 6+2 & the 4+4 CPU slots on the PSU?

 

as @GoldenLag mentioned will it be dangerous to plug my GPU into the 4+4 CPU slot on the PSU? or is that another PCI-E 6+2 slot? If so I'm a bit confused why they named it 4+4 CPU.

 

A lot of people have mentioned using two cables because the vega is power-hungry.

 

Again to you both thanks for the help

Yes, it's better to use two separate cables for power-hungry cards that require two 8pin connectors.

Your PSU doesn't have any CPU-only slots or PCIE-only slots. The two 8pin slots are either for two PCIE cables, or two CPU cables, or one PCIE and one CPU cable. Each one accepts both types of cables. That's what I was trying to explain in my post.

As I was trying to explain, they didn't name that slot 4+4 CPU. They named that slot "6+2 PCIE & 4+4 CPU", because it's for both cables. Both 8pin slots are for both cables each.

dont plug it into the CPU power. if im not misstaken it probably has a different pin layout. which would run the risk of killing some hardware.

that is 2 different cables from a PCIe power from the PSU. its what some people had to do to get those card running due to poor PSUs.

Yes, you are mistaken. This is my third post about this. The 8pin slots on Corsair TX650M accept both PCIE and CPU cables. Why are we going in circles?

any powerconnector labeled CPU should never be plugged into the GPU. so id read what he said there once more.

because some board only have a 4pin CPU connector. 

 

do not plug anything labeled CPU into the GPU or PCIe into the CPU. 

 

cables labaled PCIe goes to the GPU or other PCIe cards.

Im reffering to the cables labeled CPU and the cables labeled PCIe. Do not switch those around. 

 

4+4 is a CPU power end. And 6+2 is a GPU power end.

Who said anything about plugging CPU cables into the graphics card?

We're talking about powering the Vega with two separate PCIe cables, instead of one daisy-chained PCIe cable with two connectors.

That's not what @Xcel is asking about, and you completely missed the point of the topic.

Welp. I missunderstood then. Thpugh he was reffering to plugging the 4+4 pin CPU connector into the GPU. My apologies

No worries, maybe I got a little heated too. Mistakes happen.

@GoldenLag @OrionFOTL

 

Sorry if there has been any confusion in this thread. I was wondering if I could use both the slots on the right hand side of the PSU photo to power the GPU. OrionFOTL has mentioned I could.

Well, i do take a more aggressive approach when i realize there might be Hardware at stake. 

 

When it comes to using 2 seperate cables onstead of the one daisychain. I can only find one 12v rail on the PSU. Meaning for @Xcel it wont matter to use 2 different cables. So id just stick with 1.

When using 2 separate cables instead of one, you cut the current flowing through them in half. This means less resistance in the cables, which in turn translates into smaller voltage drop through the cable and the cables heat up less as well.

 

Seasonic cares about it so much that they even include this snippet in the manual with their power supplies:

It appears you can, but remember to use to correct cable. 

 

Also there appears to be no reason to use 2 seperate cables to power the GPU. So just use the one daisychain 2 8+2 pin connectors

Isnt that in relation to their sensetive OCP?

 

Yes less resistanse is good, but the cables are rated to handle it. And voltage drop during load happens anyways. And UVP protects for any potensial issues should they occur

[Xcel]

This was the photo I saw which got me worried about using 1 cable... I was trying to find this again. @GoldenLag I think the vega 56 comes with a warning, not to daisy chain (I'm assuming it is due to what @OrionFOTL has mentioned above). 

 

Thank you both (you've been amazing help). I think i will use 2 cables as the photo shown above!!

Thats a warning im unaware of then. Because of the dual 6+2 pin cant handle the ATX spec. Then why have a dual 6+2 pin.

 

Sounds like a poor PSU or multirail PSU current balancing.
