My old 3770K system died and I am re-building it as a 10700K system.
As I can't afford to do an entirely new build, I am going to be re-using most of the parts from said 3770K (In fact, the only reason I am not going with my original plans of a 9700K is because I managed to get both the CPU and RAM quite a bit cheaper open-box at MicroCenter). The case, the drives (yes I know, there are a lot of them), the additional cards I had in it, the fans, the GPU, and just about everything else will be re-used. (Was going to re-use the PSU too, until a PSU tester said that while all it's voltages are good, the PG response is out of spec, I also realized it's a year out of warranty when I originally thought I had 2 years left).
Basically I am going to be ending up with this:

But with the CPU replaced with a 10700K, 2x32 DDR4 RAM, and the motherboard with a z490 board, these parts replacing the older ones essentially:

The point of contention is the PSU. A LOT of them are sold out and/or overpriced right now due to shortages. I had a 750 watt PSU in that case. And while a 750 watt should be more than enough for a 10700K/GTX1070.... even with all the fans and several mechanical and SSD drives I have in it, since that system is likely going to last me at LEAST as long as the 3770K did if not longer, it's going to need upgrades down the line, namely the GPU.
When I tried using PSU calculators, they estimated that I would need around 625 or so watts for my current setup, not bad, well under 750 watts. But, when I calculated in upgrading to an RTX card such as a 3000 series (or possibly later models, it will be a while until I can upgrade the GPU), it estimated I could use up to 725 watts. That's cutting it dangerously close to a 750. Now, I know that some PSU calculators can overshoot (as well as others I have run into that well-undershoot) but I tried Googling it and was getting conflicting answers on if 750 or 850 would be enough, many forums posts that 750 is fine while others recommended 850.
Normally in this situation I would just go 850 since the extra cost is not that big..... NORMALLY ..... but a lot of PSUs are sold out right now. And even the ones that are not sold out are priced higher than normal due to said sellouts and shortages. (The one I want is apparently supposed to be $160 for example, but it's going for $200 on Amazon (plus won't even be in stock for about two weeks) and for far more on Newegg). So in this case I could be paying far more than the normal higher cost from a 750 to a 850 right now if a 850 is overkill even for what would be 8-10 years of upgrades from now, but I also really don't want to undershoot it and cause problems as well as the headache of having to replace the PSU early if 750 could end up being too low.
The contention on if I should get Gold or Platinum is also an issue since I keep my system running 24/7 (most of the time not at a high load) and while the winters are cold it can get fairly hot in the summer here. Titanium is going to be out of my pricerange for any good PSU at these wattages.
