Question power supply question for trio gaming z (radeon rx 6800)

[aurorius]

Hi there. I just got the above graphics card, and I'm having an issue with how to supply it with power. It has a 24-pin power supply, so that means 3 x 8-pin PCIe cable. Just not sure how to connect this to the PSU. Does this need to be connected to the PCIe 6-pin connection in the PSU? If so, does it matter if it's three separate cables between the PSU and the GPU, or 2 cables from the PSU that end up in three 8-pin connections?

Would two of these help?

I happen to have a spare 8-pin to double 4-pin adapter and a 4-pin to 6-pin adapter which I can use too. Is that a good idea? I believe that this is not recommended.

Hope all this makes sense Thanks

You need a sufficient power supply.

It is dangerous to use adapters that are not meant to supply the necessary power.

If your power supply does not have 3x 8-pin PCIe power cables, then it is not meant to power that GPU.

You likely need a better power supply.

Yup, if you're missing the proper PCIE cables, then the PSU has no business powering a GPU, regardless of whether you have an adapter. Any competent PSU will have the appropriate connectors. Now, some bad PSUs *will* have the connectors too, but not having them is a telltale sign of a junk PSU.

ive just built a system with the msi 6800xt gaming z trio it by default recommends a 850w psu

its not good practice to daisy chain pcie power connectors to the gpu so 3 separate cables running from your psu to your gpu is much better

whats PSU are you using and i would recommend a corsair rm 850w PSU with all the right cables included !!

Thank you all for your answers.

The PSU that I have is this one:

https://www.newegg.com/cooler-master-rs850-ambaj3-us-850w/p/N82E16817171048

It is a bit old (to say the least ) but if there is no absolute need to replace it, then I'd rather stick with it

I can see on the PSU that it says 6 + 2 pin PCIe, so I guess that's okay?

It's not as bad as it originally sounded from your description of the available connectors, bu there is an absolute need to replace it. You should not be using *any* group-regulated PSU with a PC with a discrete GPU in 2023, let alone one that is at least a decade old.

It's a significant enough issue that if you don't replace the PSU, I'd simply return the GPU for a refund while you're still within your return window.

I'd rather upgrade the PSU tbh. I have this one on the way already:

Amazon.co.uk

It's been ages (as you can tell) since the last time I've upgraded my desktop, so just a few more hundred won't be the end of the world.

And one final question. The PSU comes with some cables
(you can check them here: https://www.corsair.com/uk/en/p/psu...ular-low-noise-atx-power-supply-cp-9020249-uk).

There are three cables in the box
(one (8-PIN) (6+2) and two (8-PIN) (6+2)/(6+2))
but we don't want to be splitting these? I don't mind having one end of each cable hanging, I can manage to hide this.

But if I want to use separate cables, does it matter which brand it is?

Thanks a lot, your input is super useful to a noobie like me

Perfectly good PSU. You *ideally* want to use separate PCIE cables, but it's not the end of the world if two of them are daisy-chained with a good PSU, especially when you're not talking about, say, a 3090 which can really shred a PSU.
