RM650X Compatibility issue?

[AvogadrosDog]

Hello guys,

 

So I'm currently building a system based around an already purchased Ryzen 5 2600X along with an RM650X power supply already bought. I'm currently looking at motherboards and have grown quite interested in the MSI X470 Gaming Carbon Pro but on checking with PC Part Picker it states they are not compatible due to 1 missing EPS connector - is this fixable without purchasing a new PSU? (would rather look at a different motherboard, and will this be an issue for future motherboards) - can I just purchase an extra connector and it work?

 

If so, do you recommend any other motherboard along the same lines as the one I've grown interested in and around the same price point that would be compatible?

 

Thank you for any help you can offer

Just don't plug in the 4 pin connector. It's stupid and serves no purpose, even if you were to LN2 overclock the CPU.

I'm sorry but this is my first build so what do you mean by 4-pin connector and how will I know which one? The spec sheet says it requires 1x 24-pin main power connector (as normal) and 2x 8-pin ATX12V (the extra 1 is not usual or at least in most of the motherboards I've seen) - which should I not connect and why does it need 2 8-pin connectors?

 

Thanks for replying and helping out!

 

Also: is there much advantage between X470 Gaming Pro Carbon and B450 Gaming Pro Carbon? In your opinion that is?

So what he's referring to is the CPU power connector. Yes, almost  board requires a 4+4 pin connection and a 24-pin connection. Some boards sack the extra "+4" pins from the board because the board will not need more juice than the 4-pin will provide because the board locks the user out from OCing a high-end CPU on the board.

 

In the case of 99% of motherboards and CPUs, you don't need more than the regular 4+4 pin connection for supplemental power. Some boards have an extra +4 or extra 4+4 connection. This can be useful on X299 platforms, for example, where a dodecacore CPU with OC can draw over 500W on its own. If you're running a 2600X, the regular 4+4 pin connection is all you need to power that chip no matter how hard you hammer the thing overclocked, even on LN2.

 

Those boards are, for all intents and purposes, the same, with one allowing for X-series board specialties, such as SLI, potential better memory compatibility, and well that's about it, Both boards have a pretty lackluster VRM for overclocking, especially the X470 board given that it uses the same VRM as the B450 board. However, MSI seems to care more than other board manufacturers about memory compatibility and keeping their BIOS' up to date. For a 2600X, if you don't plan to OC, get the B450 board. If you do, take a look at the older Asus X370 Prime Pro.

Thanks for the explanation! I'm still learning so I appreciate you going through the effort of explaining this to me - much appreciated.

 

My concern is primarily because I'm looking to somewhat future-proof in case down the line I pick up a Ryzen 7 and want to overclock. I'd look at the X370 boards except I'm worried they'll need a BIOS update but that is easily done by downloading the BIOS drivers from the manufacturer's website correct?

Thought the X470 Carbon had an 8 pin CPU power and a 4 pin CPU power connector. Just plug in one of them. Even some X299 boards only have a single 8 pin, you're fine.  

The extra connector is just silly marketing stuff. Some people apparently think it'll help them overclock. 

Quite often, the X series boards have higher a higher end VRM, but I'm not sure about in this case.

And, for the record, you can buy an extra EPS12V cable if you really feel you need it.
