    Default Can I power my evga 1070 with 8pin pcie connector and a 2xmolex to 8pin adapter?

    PSU is Seasonic S12ii 520w bronze. It only has one 6+2 pin pcie connector. I'm thinking of using a 2xmolex to 8pin adapter for the 2nd 8pin slot. Is this recommended?

    CPU is FX 6300 (which is up for upgrade along with PSU next year)

    The Seasonic S12II 520W Bronze has two PEG connectors. A molex to 8 pins PEG connector is a bad idea. But your PSU is also getting quite old, it's a 10 year old design which isn't build for a modern PC. For a modern gaming machine a modern power supply based on a LLC resonant converter design with DC-DC converters works a lot better.

    Doesn't the S12II come with two 8 pin connectors?

    Pretty sure S12II 520W has two PCIe.

    But to your question: A Molex only has one +12V wire. Two Molex is two +12V wires. So splitting two +12V wires to three isn't the best idea.

    the S12 520w has two pcie connectors , its an old design but i think if your PSU wasn't used heavily it would hold up until you upgrade.
