I'm running these cards from a 990fxa ud3 r5. My power supply doesn't have the 8 pin support. I don't run any IDE's so the power supply has 4 available. Are there any adapters I can find or am I better off with a new power supply? This older build was bad enough. The power supply has the juice so that's not going to be a problem. It's 1000w and all rails are coverd well. I think they max at 150w on the heavy draws but I don't have all the specs. These are Asus cards if that helps. I'm done for the most part of jamming money into it but it's a question I had and I knew where to go. The exact cards are DUAL-RX580-O8G 8GB.

Any other things, please ask. All of you have been agreat help lately.

Thanks guys/ all.

Ross.
