What PSU?

[Jared1995]

I have a i7-9700, RTX 2070 Super, 16GB Ram and a Z390 M gaming motherboard

 

 Was looking at the CORSAIR HXi Series, HX750i, 750 Watt, 80+ Platinum Certified, Fully Modular - Digital Power Supply https://www.amazon.com/dp/B00M2UINC8/ref=cm_sw_r_cp_apa_i_K4fhEbJ9JS44G

 

But was also taking a look at the CORSAIR RMX Series, RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply https://www.amazon.com/dp/B079H5WNXN/ref=cm_sw_r_cp_apa_i_NsghEb3WDDTAK

 

Any advice? Are these too much?

Those are both very high-end power supplies, of course you're looking at wattages that are way more than you need. I wouldn't recommend over 650 for a reasonable amount of power, it still gives you more than you'll likely ever use off that rig.

Why not 9700k?

I know I asked myself that as well after the fact but non k is really not bad

Okay gotcha another question was the back of my 2070 super said minimum of 650w I couldn't imagine that card ever using that much but it confuses me of why is that much on the back

They over-recommend power supplies to cover their bases. You could technically be running that 2070 in a system that consumes 650 watts, it's just not the system you've listed above.

 

Also if you're gonna go with the non-k CPU, consider a B365 motherboard and some DDR4 2666 to save cost.

Alright so I'll stick with that 650 range thanks my man

This build would be good even with 550W, even OC'd 9900KS + RTX2080 Ti consumes just about 400W in gaming. Check PSU tier list, smth from tier B+ would be good enough but tier A\A+ would be a bit better.
