Help picking a psu- first build

[IDLESHARK]

Budget (including currency): roughly $1,500

Country: United States

Games, programs or workloads that it will be used for: Gaming/School

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): 

 

BUILD

CPU: 12600K

Cooler: Corsair iCUE H100i Elite Capellix 240mm

Motherboard: Asus Prime b660 ATX

Ram: Corsair Vengeance 32g 3200

Storage: Western Digital SN770 1 TB

GPU: Asus Dual OC V2 RTX 3070

Case: Corsair 4000x

PSU: TBD

 

I am currently a full-time engineering student therefore I am looking for reliability plus gaming. I opted for the 12600k over the 12600KF due to the integrated graphics. If the GPU fails or I need to troubleshoot I can use the IG to continue school work or whatever else I may need. 

I've read online in order to determine the amount of wattage required is as simple as adding peak CPU and GPU wattage. Then add 150W for MOBO, plus an additional 150W for headroom.

 

I assume I'll need a 750W power supply but I don't if getting 850w is overkill. I understand that these PSU's also have an efficiency curve but I'm not very familiar with them.

 

P.s. I know I should probably get a Z690 motherboard but overclocking is not really in my interest at this time. 

 

If I could get some advice on choosing a good power supply that would be fantastic along with any further advice on the build. Again, this is my first build.

750w will do for that build but the price increase for an 850w is not a lot and it gives you a decent boost in wattage for upgrades later.  I love my RM750i / RM850x.

Here is a list with a very(might be overkill) good PSU within your budget with your current parts.

and here is a list with a better GPU for the same price.

The 12600K and 650W is way to weak for a 4070TI, the CPU will be bottlenecked

The 4070TI requires 700W alone. 

Don't know much about engineering, but from what I've heard, a better GPU is more important that a better CPU in most engineering applications. As for the power requirements, just set power limits and undervolts. The only way to stay on budget. Or you could get a 750w, although youll get to about $100 overbudget. Also the 4070ti doesn't draw 700w. Not even close. It peaks at around 320w.
