I found the shift model is normally cheaper than the non-shift model. I know the shift model the ports are on the side. is it worth to buy a shift model for a cheaper price?
Corsair RMx Vs RMx Shift PSU Differences?

if I can put the shift model in, any difference for the 2 PSU? Why is the shift model always cheaper? Different capacitors? thanks
the shift one has connectors coming out the side rather than the back. the connectors that plug in the PSU are also a bit smaller. your case needs to be wide enough. other than that i think they should produce the same wattage. i have no idea about the pricing
There's no real world difference between the two beyond inclusion of the 12V-2x6 connector and a better fan type: https://www.corsair.com/us/en/explorer/diy-builder/power-sup…
ATX 2.53: Uses older, standard power connectors and does not have a native 12VHPWR or 12V-2x6 connector.
ATX 3.1: Features the 12V-2x6 connector (a refined version of the 12VHPWR), designed for high-power graphics cards.The Shift is slightly better based on above so cheaper pricing could just be a demand/supply factor.
thanks
probably better to get the newer ATX version
the rm850x and shift both have the ATX3.1 version
My 10-year-old case says it is not compatible with the shift model. Corsair website says a minimum clearance of 30mm from the connector side of the PSU to the side panel of your case I just measured than I have 50mm space so it should work
I just watched a youtube video and found for my cash the PSU fan will face the wrong side. the PSU fan will face the solid pannel will this be an issue for cooling?
yes, the fan needs to suck air in, preferably from outside the case, and blow it out via the grill on the back of the PSU
I found the shift model is normally cheaper than the non-shift model.
its the economics of volume at play here I think! ideally Shift includes improvements, rgb etc but is cheaper because many prefer the shift model over the other one i guess!
depends on how wide your case is, where your PSU goes and how the cables need to be routed
