[SOLVED] Strix ROG 2080 ti - 0ne or both power cables?

[johnstac]

I have an EVGA 650W power supply. I am trying to determine which cables to use to power the graphics card above. Please see the photos below so you understand what I’m dealing with. I have one cable that has to 8-pin connectors. Should I use that or should I use one connector from each separate cable?

The one cable with 2 connectors is perfectly fine and made to handle the power requirements of your 2080ti.

My 2080 Super specifically stated in the instructions not to use the type of cable in picture 1. It stated you must use 2 separate cables from the psu to the card.

Maybe protection for people using cheap power supplies. If it’s a quality PSU, that cable is made to power a single card needing 2 8 pin connections.

It's better to use 2 cables. They will heat up less.

Maybe, what is heat up less? 1 degree, 20 degrees? What is the total impact of this lower temperature? I’ve been using the single cable on a 1080ti overclocked which pulls more power than a 2080 super for almost 3 years and haven’t had an issue using a quality Seasonic Focus. Maybe your personal preference is to use 2 cables, but that wasn’t the question. Obviously he can use 1 or 2. I’d recommend one, but if he wants to use 2, no it won’t hurt nor help IMO.

It depends on wire gauge.
With bigger diameter, less energy gets converted to heat.

And if you're doing any kind of GPU overclocking, then you have to be very careful or end up like this guy.
