6 pin splitter?

[Plumpeken]

Hello, I am going to crossfire my 7870 with a r9 270x. My power supply only has 2 6/8 pin connects on it. It's 600w I went on cooler Master power supply calculater and it will be enough to power. But what should I adapt to 6 pin? Should I get a 6 splitter? Or 2 melex to 6 pin?

 

Thanks,

doesnt crossfire require two identical cards?

Nope, AMD isn't as restrictive as Nvidia

wait could you crossfire a rx 580 and a 5770

No. They have to be based off of the same GPU. You can crossfire an RX 470, 480, 570 and 580, with them all tuning themselves down to match the 470, because they all use the same chip.

Theoretically yes. The problem about it is, that the VRAM of the RX580 will be reduced to the 1GB of the 5770.

 

So I wouldn't suggest you to do that.

 

 

However pairing a R9 270X with a HD 7870 would be completely fine since both have 2GB VRAM

No, you cannot crossfire two different GPUs. See my explanation above this.

Thanks,

sorry we got off track. I would use molex

Right...I've got that one wrong, saw your explanation only after I posted mine, since I was still writing

I could have sworn I've seen benchmarks with crossfire between a rx480 and gtx 1070 once but can't find them anymore. It had interesting results generally out preforming either card in normal crossfire/sli by slight margins. But I can't find it so mayhaps it never happened. You probably know better than me anyway.

So is molex the better choice?
