Is this overkill good

I was recently buying parts for my gaming pc build. When I came to my psu I was confused. I was putting in a ryzen 7 2700x and rtx 2060 SUPER. So I decided to get a 650 watt psu. The 650 watt psu was 80 dollars and the 750 watt was 110 dollars. They both were 80+ bronze, semi modular, and both from Corsair. However a deal on amazon for the 750 watt made them both the same price so I ordered the 750 watt. Now I am questioning what I ordered. Did I do the right thing? I know this is overkill,  but will it do anything bad.

CPU: AMD Ryzen 7 2700X

MOBD: MSI B450 TOMAHAWK ATX

Memory: OLOy WarHawk RGB 16 GB (2 x 8 GB) DDR4-3600 Memory

HHD: Seagate Constellation ES 1 TB 3.5"

SSD: Team MS30 256 GB M.2-2280

GPU: NVIDIA GeForce RTX 2060 SUPER 8 GB FOUNDERS

Case: NZXT H510 ATX Mid Tower Case

PSU: Corsair CXM 750 W 80+ Bronze Certified Semi-modular ATX Power Supply

Case Fans: LEDdess Wireless RGB LED 120mm Case Fan with Controller for PC Cases, CPU Coolers, Radiators system

Case: NZXT H510 Mate Black/Black

CXm most likely. It's decent but for RTX2060S i'd get smth better. But if you can't return it then it's fine. It isn't about wattage, good 550W unit would be enough for any gaming rig.

Tag or quote me so i see your reply

but what if it's a TXM? CSM? thankfully it wont be a VS or a GS, assuming both are the same model as they lack 750w variants.

is it on a system that'll pull around 300-350w?

 

a good 450-550w psu will perfectly do here, what options do you have on that level?

It's not overkill. It's good to have the extra head room for adding more drives and/or upgrading to more power-hungry components in the future. if you ask me, that's worth an extra $30-40

PSU wattage won't hurt it, think of it as a limit of how much the components can pull, not that it's pushing 750W to the components, but it depends if you compromised quantity for quality.

Quote or Tag people so they know that you've replied.

it's the quality that matters, not how many watts you can pull of it. i can easily do 600w on a half-decent 550w. I'd much rather have op here have a better 550w than a budget 750w

discontinued, though same platform as txm if we're talking about the gold

not the old TXM (the one with bright yellow/orange label), the newer one.

Sure I agree but, I wasn't saying anything about quality. 
Even the best 500Watt PSU would fry my system.

would it if protections are a thing? i don't think so. worst case I'd just cut power

Point is that 500w isn't enough. Add in multiple drives, overclocking on the gpu and cpu, and 4 sticks of ram and you'll be running out real quick.

can you take reviews from someone like toms with the 2060s and the 2700x, when they measure from the pins, add 50w to that and tell me the exact number you got? if that's above 500w, you calculated wrong

Like adding 10x Kingston Fury RGB ssd in full flash mode and so on? I guess there'll be bigger problems then.

Adding 4 sticks of ram and a couple drives gets the PC to almost 400 watts at stock clocks. Overclocking will go well above 500. That's not even considering voltage fluctuations.

Now say they decide to upgrade their CPU and GPU down the line (here I used the 3900x and a 2070 super)
And they're within 30 watts of the max.

If you spent 2 seconds to see how PCPP got to that estimate, you should've seen why I consider random.org to be a better PSU calculator than any PSU calculator. 

Spoiler

Tell me, how will any voltage fluctuations affect this number?

Here we go again, sure it's good to have some overhead just in case you'll decide to go all in but that'll affect only the acoustic performance of PSU, good 500W PSU are enough for any single-GPU build in gaming conditions.

i9 9900ks 5.2GHz + RTX2080 Ti consumes just about 400W, enough headroom for a ton of misc parts and again, with good PSU, transients are nothing to worry about as they're 30-40% overbuilt.
