[SOLVED] Is there a (safe) way to run a Vega56 from an Antec TruePower 550W (regarding power supply cables)?


Feb 1, 2016
I have a system that I bought a Sapphire Vega 56 for. The card has two 8-pin power connectors, and I realized too late that the power supply (Antec TruePower 550w) only has a 6+2- and a 6-pin connector. Is there any way to still use the power supply to power the graphics card? Are Molex to PCIe-Power connectors a (reliable) thing, or are there other solutions? If possible, I would like not to buy another power supply at the moment, but if that's the only solution, so be it.

I read that the possibilities depend on the quality and design of the PSU, but I have absolutely no idea about electrical stuff. Does the power supply meed the necessary requirements?

Disclaimer: I am not concerned regarding using a 550W power supply for a Vega 56. I have another system in which it runs with an even smaller one, and several wattage calculators leave me confident that 550W should be sufficient.
