Corsair Cable Compatibility

[kickingaustin]

I have read numerous posts and watched a couple videos and tried to understand this funny chart. But I just don't get it. There is no source/destination PSU and they put a red dot(meaning type 3) into a row that says type 3 already. So it's either redundant or I don't know what I'm talking about. It also shows type 3 and type 4 under a single column, meaning a single line of PSU's can use both?

Can I get a real explanation on how this thing works?

 

I have an RM550x and want to upgrade to an RM750x or RM850x. I should be fine (I think), but I'd love to just know how to read this chart.

 

Thanks!

All RMx PSUs, regardless of wattage or version (other than the RMx Shift) use the same cables, Type 4. The only difference between Type 3 and Type 4 is that the 24 pin connector has 4 extra pins on Type 4 cables (but is still otherwise compatible if you jam in a Type 3 cable into a Type 4 PSU). So the RMx can use Type 3 and Type 4 cables, but the 24 pin is Type 4.

Thanks for the explanation.

According to the chart then, RM2019, RMi, and RMx are all compatible? They have the same dots of the same colour in all the same spots. The colours make things confusing, because I feel like they could all just be checkmates in this case.

Is that correct?

Yes, that all sounds correct.

You do know when you buy a psu it comes with its own cables right?

I do, but it's an ITX motherboard with a big cooler and I don't want to remove the huge cooler and repaste the cpu and re-manage all the cables if I don't have to. I just rebuilt my PC a few months ago and didn't want to do it again. That's all.
