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

[Simonky16]

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.

definitely not molex to PCIE imho. Vega 56 max can draw 300 W. 550 is cutting close. If no budget for new psu, best bet is some expansion cables for Antec. Check if your model is compatible. https://www.ebay.com/itm/18AWG-PCI-...n-to-Dual-8pin-for-Antec-ECO-TP-/122309700541

I will probably get a better PSU for the sake of expensive GPU.

If you have only a 6+2-pin and a 6-pin, then there is no safe way to use this power supply.

The safest solution:

Step 1: Remove the Antec
Step 2: Acquire a more modern ~550W PSU. Something made in this decade would be preferred.
Step 3: Install said PSU.
Step 4: ...
Step 5: Profit.

just buy a modern power supply and use like a 600+ watt psu and get a 80 percent bronze or higher.

also make sure that Antec PSU is nowhere near your PC. it would be a shame for your impressive battle station to be destroyed by some pesky PSU
