Question about the compatibilty of my RM850i I bought in 2016.

[MyAIOisbonkers]

Is my RM850i I bought in 2016 outdated for use with the latest boards from Intel and AMD, and for the latest video cards from Nvidia and AMD?  

I think I have enough 8-pin PCIe(4 of them) connections at the PSU for the motherboard and for one new video card requiring 2 8-pin power connections.

If the sentence, above, is true, is there anything else I'm still needing from a new PSU that my RM850i from 2016 doesn't provide, aside from more power, if I upgrade my 2080 Super to something more power hungry?

Note: I tried finding details for my RM850I, to no avail.  I wish Corsair kept a database on their discontinued products.

as long as it's powerful enough for the rig you want to assemble, it will be alright.

you usually only need one EPS12V cable for the CPU which leaves 3 spots free to power your GPU. If said GPU uses the new 12VHPWR connector, you can get the corsair cable that only takes 2 connectors on the PSU side.

Thanks for responding.  So far, the mobo's I've seen have either 1  4-pin and 1  8-pin EPS12V connector, or 2  8-pin EPS12V connectors.  Even motherboards be gettin' more power hungry.  lol

Well, one 8 pin can supply over 300W. No CPU yet on the market takes that much power continuously unless you heavily overclock it. And those that are close to that value out of the box like the 13900k and highest end ryzen benefit more from slight undervolting than brute force overclocking as we used to do with lower core count CPUs. They bump on thermal limits before reaching power limits.

So yea, all in all, no need for more than one 8 pin unless you play with liquid nitrogen.

I'm not debating how much power the board needs.  All I think is if I have a board w/ dual connectors on it, don't those connectors have be populated with the required EPS12V plugs from my PSU?  Is this not the case? 🙂

nop. The 12V are all connected together, and the grounds are all connected together on the board. It works fine with just one connector populated.

Thank you for the knowledge.  🙂
