Hi all im trying to pin point if this is simple a cable issue - a power pack issue - or a motherboard issue.
My specs: Ryzen 5 - 2600 - 16 gig of ram - msi-b450m pro vdh max - OCZ mod x stream - pro 700w power supply - Windows 10 - 64BIT fully updated.

Issue: My previous graphics card was a GTX 960 - When I put my new card in which is a sapphire RX 6600 - The power refuses to even switch on. Even if something was wrong it should surely power up at least. I put my old card back in the board and wired it back up again, it then boots up and fully loads in to windows without issue. I am using this cable, for the new card.

Even if the motherboard needed an update it would surely still turn on at a minimum with the new card installed.
Head scratch for sure lads.
thank you

Hi and welcome to FpcH

Your old card used a 6 pin power connector.
Your new one - from what I can find - uses an 8 pin power connector.

Is this correct and do you have the correct power connection for your new card?

Check that the card is seated properly and that you have power to the card itself.

It fixed now - turns out my power pack was old - and i needed specific cable that came with the power packs/motherboard to fix. Thank you for your help! Basically a new power pack was needed with the cable that came with them.
