Corsair RMx. Any reason to not buy 850 if it's cheaper than 650?

    I am wishlisting components for a build. I had kind of settled on the Corsair RM650x, but there is a sale right now, that has the RM750x ($119) and RM850x($129) as cheaper than RM650x($135). (prices are Canadian).

    Is there any reason at all to NOT get the 750 or 850 when even the 650 will likely be overkill for my eventual build (6-8 core CPU, single Midrange GPU).

    Or is there something better in this price range?

    The only "downside" to getting either bigger model is you might be in a (very slightly) lower efficiency range, which will never eat up the price difference.

    Buy the 750 and enjoy.

    I have always regretted buying the lower capacity PSU because i didn't need more power. I always end up needing more power. This is likely not true for most people however.

    I had a 650 and now the 850. I probably did not need it but upgraded when I got a 2080 super and 3900x. I like that the fan never comes on since it never gets hot enough for it.

    Most psu’s now are at peak efficiency and lower temps. Buying more than you need, runs cooler, less noise, and better efficiency.

    That would be kind of cool it was essentially a passive PSU, even while gaming.

    I dithered until the 750 went up in price, making the 850 the cheapest model. So I just ordered that one. First component of my next build.

    Now if only MSI would bring the Mortar B450 Max to Canada, I'd pull the trigger on everything else. But I may go Intel if I can't get an AMD MB I like.

    I never saw the fan turn on in my old case where I had the fan facing up and could see it through the window. When gaming or even when running something like Prim95 for 40 minutes. Now it faces down in the new case but I pull the filter every now and then to check on it and there is not even a dog hair on it let alone dust so if must not bet spinning ever. Shit I do not even know if the fan works to be honest.

    Better to have it and not need it than need it and not have it. Go bigger especially if it's cheaper.

    I will toss in a recommendation for the RM850X as that's what I have in my main PC and it's been rock solid for 2 years. On a side note, woah; didn't realize I've had this PSU for 2 years already.

    I have the 850 here now. Though it will probably be a while until I get the components for a build to go with it.
