PSU recommendation on PCPartPicker is true?

[SirLouen]

After building my computer on PCPartPicker it says that the Estimated Wattage is 470W.

Does this mean that I will fine with 500 or 600W for this build?

Or should I go more conservative, up to 750/850W?

For example, I was checking this build I found in a post some months ago, and I can't understand why going so far up to 1kW PSU https://pcpartpicker.com/list/Q9frVW

What are your recommendations in this regard?

The 80 plus rating is rated at like 50% capacity continuous duty, so you can get a 650-750 and be golden. You can get a 500w and be okay, but riding the edge at 100% duty

In my opinion, you want the PSU to run no more than at about 80% max load. A 600W at 80% is 480, so that would be my personal minimum recomendation, you can go higher, but don't get a higher watt PSU at the expense of quality.

What's your GPU? Factoring in your GPUs transients will be the biggest factor in determining what PSU to suggest.

For this particular setup:

I was planning on getting this PSU

At 750W which I personally like

I assume it will fit perfectly since it's way beyond that 80% mark.

But matt comments, that it is at 50% capacity continouss duty, so I'm talking about 470W in this scenario, then it will be required at least 1000W to fulfil this, right?

I would go with something that's based on a modern ATX 3.0 platform like

https://www.newegg.com/seasonic-vertex-gx-750-750-w/p/N82E16817151259
which now comes with a 12yr warranty.

Or If you want the best of the best and don't mind paying for it,

Wait a second

I chose specifically this PSU because it was Titanium + ATX 3.0 at the same time+ it has a nice discount in my country (only the 750W version).

Am I missing something?

Sry I read 12 not 13!

 

[SirLouen]

So the conclusion here is that 750 W is viable or is a mistake?

No, no, 750 is solid for your build. You're gtg.

Altho, you may want to bump it up to 850+ if you see yourself upgrading to a more powerful GPU in the future.

Yeah I've been doing simulations

But unless you move up to a 4090, nothing seems to require anything bigger than 750W

Like everything in life, the thing here is with my budget under $200 for PSU I must choose

A) 80 PLUS Titanium at W sacrifice
B) 80 PLUS Gold without any W sacrifices

And the reality is that I don't have money and I will not have either, in the future, to afford a 4090, 5090 or the liking. Not even a 4080 or 5080. My max aspiration in life is a X070 so basically I can't hardly see a situation where anything beyond 750W will be a thing (according to the calculator)

But something interesting, is that maybe at one moment, I would need say, to purchase 2 units of 5080 cards in the future for some kind of niche processing thing like AI ML models or the liking. In that point, not even a 850W will save me. Not even a 1000W will be trustworthy, only a 1200W or similar. And I'm not going to buy a 1200W "just in case". Because I can't even know if I will need only 2 units, or a 4-pack rig.

So basically I think I will stick to the 80 PLUS Titanium, 750W for now, because at least the Titanium thing seems to look very nice in terms of performance.
