Question Daisy chain for Sapphire Nitro+ RX 7900 XTX?

[Mingusus]

Hi forum

Can I use one dual(split) 6+2 PCIE cable and one single 6+2 PCIE cable for my GPU?

I only have two single 6+2 PCIE cables to use and a bunch of dual(split) cables.

I have a Corsair RM1000i in multirail configuration.

The Sapphire Nitro+ has 420 W TDP instead of the common 355 W TDP

Thanks
Mingusus

It's always recommended to use 3 separate 8-pin PCIe power cables, but it may work fine with a good quality splitter.

If this is your card;

then you can work with 2 standalone 8pins stemming from the PSU while the daisychained harnesses can be albeit with the pigtails not being used.

For the sake of relevance, how old is the PSU and if you're yet confused, adding images of the cables you have would help us(everyone) two fold.

A thumbrule with a PSU/build, if your PSU lacks the necessary connectors for your build you either have;
a| the wrong PSU for the job
or
b| the wrong components for the PSU in your build.

Hi Lutfij

My PSU is 6½ years old.
It has plenty of connectors (See here):

I am using cables from this kit:

My PC specs:

I could just buy some more single cables. However it would be nice if I could make it work with what I've got.

So I can just use two normal single 6 + 2 cables and use a single 6 + 2 connector from the split cable?

Yes.
