3 8-pin PCIe cables need for 7900XTX

[spg-shubh]

I bought the ThermalTake Toughpower GF3 1000W to power my PC Build that includes a MSI Gaming Trio Classic Radeon 7900XTX. Now I found that the package includes only 2 8-pin PCIe cables with daisy chaining available.

Do I need to buy separate cables as reading https://file.thermaltake.com/file/qig/Connect_PCIe_Cables_to_High_Power_Consumption_GPU_en.pdf suggests that I shouldn't be daisy chaining. If so, where can I buy the approriate cables from.

Thanks

HI spg-shubh

It is ok to use daisy chaining to your Radeon 7900XTX.

The AWG of main 8-Pin PCIe cable is 16 which is same as 12+4pin cable 

Therefore don't need to buy more cables to support your Radeon 7900XTX

If there is any question, please let us know.

Hello! I'm pretty much in the same situation (my card is XFX Merc 310 7900XTX). Could you please specify power outputs of 6+2 PCI-e cable 1) if using as a single cable and 2) if daisy chaining (using the main cable + the pig-tail)? I've seen benchmarks that 7900XTX can have ~530 W spikes that are ~20 ms long (https://www.techpowerup.com/review/xfx-radeon-rx-7900-xtx-merc-310-oc/37.html)

Does the one you use work well? Can you give me a reputable site to buy products?
