@Rosemary i plugged it in and turned on the power, tried to start it twice, unplugged about 10-15 sec after initially turning on the power

@pearshapes You've applied reverse polarity power to the card; the EPS connector has the +12V on the opposite side of the connector than the PCIe connector. I couldn't tell you whether that fried your card or not, not without knowing more details about the way the card is designed, but I would suggest you start looking into the RMA process.

@pearshapes Does your power supply not have an 8-pin PCIe power connector?

@pearshapes Don't feel too guilty if you did damage the card. The connectors that they use for these things are poorly designed to the point that you can force them into each other quite easily even if they're keyed differently.

@Rosemary yeah.. if it doesnt work ill send a message to the seller. they sent me the wrong brand anyway

@Rosemary my cards an RX 580 and i run on a 500w power supply

@pearshapes All graphics cards use the same power connector, or at least one of two; there's a 6-pin and an 8-pin PCIe power connector. Most power supplies, to our understanding, come with at least one cable for that. Often they'll have what's called a "6 + 2" pin connector, which is simply a six-pin connector that also has a two-pin connector that you can add to turn it into an 8-pin connector; they look like the image below.

@pearshapes What model is your power supply, do you know?

@Rosemary i dont.. im not currently at my pc so i couldn't tell you offhand. i do not think its got any support for 6+2 / 8, though, older model i believe

@pearshapes That's okay, then. If it does have six-pin connectors, you can get adapters very easily that convert two six-pin connectors into one eight-pin one. In fact, we have one of those that came with our graphics card that we're not using, we could probably send it to you cheap if you want. It might be easier or faster for you to get it somewhere local, though.

@Rosemary its ok! ive something on the way. i appreciate the offer though
