The RTX 3000 cards and power supply requirements

Now to me, if the official source says you need a PSU of xyz then they must be saying it for a good reason.

I know you're playing "Devil's Advocate", but a 'one size fits all' power recommendation which covers everything from a Ryzen 3100 through to a 10900k or TR 3990X? Really :confused:

No terms are attached to the recommendation, so presumably it covers consumer parts, at the very least. And even there, power demand (sans GPU) can vary by a good 100W-200W (or more, if overclocking a high-end chip).

The 3080 is rated as a 320W card. Paired with a typical mid-range Ryzen system, 600W is going to be plenty.
 
Looking here https://www.asus.com/microsite/power_supply_calculator/ you can have an idea also looking here the 2080ti already drawn 320w peak power, with the calculator there technically a 620/650w quality PSU should be enough for a 3080... however like 10th series (if anyone even wasted money on that inefficient rubbish) is like 125w vs 95w already making it overload.... it is very much a sensible thing to look at quality or not, perhaps 750w are the safest option.

I was looking to upgrade my BeQuiet to a 850w newer version however it seems newer aren't in stock anywhere, not even here :) mine has been super never heard it nor had any issues is silent as not even being there... shame these cards aren't really efficient and they went "intel" on them just feeding wattage...but price is good at least this time!

I would stick with your PSU as is and test. I am sure I read that if the card is not getting enough power it has an indicator LED. Secondly, your monitor setup, CPU, overclocking, Hard drive config, resolution , refresh rate, game playing and even where in the game you are all matter. When on the windows desktop its draw is minimal and progressively increases. It will only draw the max power when running at absolute full belt and if you are not running 8k you may never hit full power draw.

below is from Nvidias own page re the recommended specs

2 - Recommendation is made based on PC configured with an Intel Core i9-10900K processor. A lower power rating may work depending on system configuration.

Note: The above specifications represent this GPU as incorporated into NVIDIA's reference graphics card design. Clock specifications apply while gaming with medium to full GPU utilisiation. Graphics card specifications may vary by add-in-card manufacturer. Please refer to the add-in-card manufacturers' website for actual shipping specifications.
 
I've had no issues running multi GPU's for quite a few years including currently 2x 2080 Ti's, a 5ghz 9900k with tons of USB devices, RGB ML fans, strips, multiple 3.5" HDD's and an H150i AIO on an AX860i 860w PSU.

750w+ will be plenty for a single 3080/3090 along with a 10900k/3950x. As usual PSU recommendations are massively overblown.
 
If it's a quality PSU, 80+ 750W will be plenty with the caveat you're not running a threadripper with 64 cores and 20 hard drives rofl... (yes I'm being silly).
 
Just roughly calculate your total power use then aim for 50-80% of psu rating. Most efficient and should never have an issue with a good one.
 
So Many issues every company today has to deal with.
Watching their backs - suppose the PSU produces horrible ripple or noise and destroys the PC whose liable ?
Worse still suppose it all gets very hot and damages things or worse catches fire.

Then there's the green issues, taking it out of its efficiency sweet spot means it will use more power than it might otherwise do. Bad publicity for a company based in California.

Catch all safety - there are a lot of PCs out there and they have to cover all eventualities.

So 650W might be OK but it might not as well.
 
For those worrying, invest a tenner into a wall power meter. You'll be suprised how little power your PC draws. Mine has a thing that shows max draw and I've just about hit 500W with a fully watercooled OC'd 5820K and OC'd 1080 - that's at the wall so before inefficiency of the acdc conversion so less than <450W from the unit. I severely doubt the 3080 could draw an additional 200W over an OC'd 1080.

why has the performance per watt got so bad on the 3000 series?

Perhaps cause the performance has gotten so good?

Which one do you have?

My gtx1080 won't even boot unless 2 power cables are used.

I'm very tempted by an rtx3080, but going to hold out until around Christmas/new year and hopefully we'll have some rdna2 stuff by then too.

I'll be keeping my Superflower 750w psu anyway.
