Seasonic has recently updated their wattage calculator tool to include the unreleased AMD Radeon RX 7000 series however it is currently unknown if the power information comes directly from AMD. The RX 7900 XT and 7800 XT are both listed as requiring a 750 W power while for the RX 7700 XT a 650 W supply is recommended with these values all aligning with those of the corresponding Radeon RX 6000 models. The RDNA 3 architecture of these new graphics cards is expected to increase performance by up to 40% according to recent leaks with AMD confirming they are targeting a 50% performance/watt increase over RDNA 2.

And there was nVidia gpu news right under this news... :rolleyes:
Tbh that's more like placeholder for me imho. Does Seasonic already know something at this point?

They know the GPUs are coming and its just a placeholder for now

This needs to change, using "recommended XXXw PSU for this GPU" by itself. There should add a side note that its psu recommendation is based on what wattage the cpu is.

I can see that one guy saying he doesnt understand why he's having power problems overclocking the CPU & GPU, since '750w is what they said was needed'.

You can be sure Nvidia will not include a warning that it needs 900 watts, and instead will just say somemthing like 950w psu recommended.

The Seasonic calculator seems unable to sell me anything below 450 watts. Is that the baseline for a Pentium with IGP now?

No.
Seasonic has 400 W offers.

There are no name PSUs rated at 350 W. That are extremely cheap, actually, cost around 9-10 euros.

A Ryzen U is only 15 watts, while a typical desktop configuration should not consume more than 100-150 watts.

idk 3090/3090ti, it looks pretty straight forward to me - 400watts for the system ¯\_(ツ)_/¯

I mean, if I have a 400W GPU I wouldn't risk it with anything less than 850 Watt PSU.
The CPU alone is gonna add at least 100 Watt at stock and you're probably gonna have some other stuff like an HDD an anything you plug in the USBs and you want to be safe even with any power spikes.
Also you may want overclock headroom.
In general I don't like going with "just enough" power, you may have bad surprises and the price difference isn't usually that big.
For example a corsair RM680x is 107€ on amazon, while the 850 is 135€.

b-but there's no way a 6800 xt would be faster than a 2080 ti!

Companies only give suggestions under stock safe settings.

its pretty much in the footnotes (if people would read them!) what system configuration is and its not all that hard to find reviews for a baseline if not also OC power consumption. comprehension is understanding what meant by "depending on system configuration"

however i do doubt that *any* configuration ran furmark and prime95 at the same time but then who does?
except me to stress test my psu :p and never a fail . . .

Those PSU recomendations are flawed anyway when GPUs have power spikes much higher than whatever their comsumption is because it's more important to win some hypothetical race than to have a good product I guess.

The solution is buy mid range where things are tempered down and more sane, everything points more and more towards a completely idiotic lineup next generation with outlandish power consuption in the interest of winning the halo race.

You can undervolt any graphics card, too. There are some good examples:
TaraquinDid a few test runs today with my 5700XT reference design in Shadow of the tomb raider with different voltagesettings etc. Tested with TAA, dx12 and highest in 1080p. Custom fancurve. Temps are maxtemps.

Stock 2050/1200mv:
110fps, 185W max, 160W avg, rpm 2950, gputemp 74C, junction 93C
1900MHz/1000mv:
110fps, 149W max, 130W avg, rpm 2700, gputemp 70C, junction 81C.
1800/950mv:
108fps, 133W max, 115W avg, rpm 2300, gputemp 66C, junction 74C.
1750/910mv:
106fps, 134W max, 110W avg, rpm 2300, gputemp 66C, junction 74C.
1700/890mv:
104fps, 126W max, 105W avg, rpm 2200, gputemp 65C, junction 73C.

Conclusion:
Underclock to 1900 and UV to 1000mv gives no performanceloss, but temps are better and slightly less noise.

Underclock to 1800 only gives 3% performanceloss, but reduces powerusage by 10-15% and temps quite a bit.
Underclocking/undervolting further yields 5% lower power pr 2% performance and is not worth it in my opinion.
Seems like 1800/950mv is the sweetspot 8n my card

Literally no performance loss.

Wish that could come true. It'll be great news for performance-per-Watt lovers like me.
