Hello, I'm new miner Wink so please be patient with me.

I bought a used Avalon Miner 921 20th/s it started to mine good but after a couple of days, all the PCI power connections get burned. I realize the smell of burned plastic and immediately turned off. but now I have all the pic connector burned i don't know why this happened. Is there someone who can help me?

Why this happened? should I change the connector and keep mining or do I have to do something else?

Sorry about my English xD

I can show you a picture if it's necessary.

Also, my miner was working at 97 degrees I live in Venezuela the people who sold me the machine told me that temperature is ok.

Well i didnt star yet and i dont have eny device just want to know what to buy. A miner o graphics cards. Energy cost here its almost Free less than 0.01$ monthly for my house.
