OK - I finally figured out why there is conflicting info on this product.  Corsair has two versions of the RM750x.

The one that I was looking at is model CP-9029179-NA.  Sometimes it's specified as RM750x (2018)

https://www.newegg.com/corsair-rmx-series-rm750x-cp-9020179-na-750w/p/N82E16817139233

It's spec's show:

  • Compact 160mm size for easier builds. (RM550x, RM650x, RM750x, RM850x)
  • Compatibility
    6th generation Intel Core processor Ready (Intel Skylake and Z170 motherboards)
    ATX12V v2.4 and EPS 2.92 standards and is backward compatible with ATX12V 2.2, 2.31 and ATX12V 2.01 systems

It sounds like this should work.


That is one of the few that actually list that backwards compatibility.  Hope that's true.  Great PSU and is really quiet compared to the CX you were looking at.

If you have a Best Buy nearby, I did pick up the 850W 2018 version of that just a few weeks ago and they matched Amazon's price for it.  They have both the 750W and 850W in stock at the closest BB to me.    They will match Newegg as well. 

You have an upside to this as it's a really nice PSU that you can take with you to your next machine as well.

Thanks - I had already picked up the RM750x at a local computer store on Friday.  It was on sale at the same price as Amazon Canada, plus there is a $20 mail in rebate. 

I hope it works !

Re: Studio XPS 9100, PSU replacement

I installed the Rm750x a few days ago, and it seems to be running fine.  It appears to be much quieter than the original PSU.

The installation was pretty straight-forward and it fit in the case without a problem.  It's height is actually a 1/2" or so less than the original PSU, so there is a slight gap at the back of the case that I need to eventually fill in with a piece of metal.

Thanks for all who gave me advice to get this done !
