Is it safe to run one 8 pin power cable to a gpu that requires 2?

[JustinNgos]

I just bought the rx 5600xt gaming mx and it requires 2x8 pins and my brothers pcs psu only has 1 8 pin cable. Is it safe to run with just one? If it’s safe to run what port should plug in, right of left?

You'll almost certainly not get a post with just one plugged in. It won't damage anything but it also won't work.

What model is your brother's PSU? (Not just wattage, but also the brand and model number)

Depending on which PSU you have, it might be safe to get a molex to 8-pin adapter, especially with the relatively tame TDP of the 5600XT

Although, like some models of the RX 580 that used an additional 6 pin connector, one 8 pin might be optional. Nitro + comes to mind.

Um... it came with his prebuilt, off brand crap. I’m guessing 400-430w?

Thanks, I’ll just get the psu for my pc now then.

Can you send a picture of the label on the PSU?

Adapters like these do exist: 

https://www.amazon.com/Power-Express-Video-Cable-Adapter/dp/B007Y8FSMQ

https://www.amazon.com/TanQY-2Pack-Molex-Express-Converter/dp/B07HKT5SGR/

BUT they are generally considered much less safe than getting a proper PSU with the correct connections.

If you're on a super tight budget, it may be worth the risk... (I'm currently using one to power a GTX 770 in my mom's old prebuilt) but just so you know, it is more risky.
