SilverStone Intros First SFX12V 4.0 (ATX 3.0 Comparable) PSU with 12VHPWR Connector
SilverStone on Wednesday introduced Extreme 850R Platinum, the world's first SFX power supply based on the SFX12V 4.0 standard, which has specifications comparable to ATX 3.0, and offers a 16-pin 12VHPWR connector capable of 450 W continuous output with excursion-tolerance within ATX 3.0 and PCIe Gen 5 specs, and improved sleep/wake performance.
The SilverStone Extreme 850R Platinum, as its name suggests, is an 850 W power supply, with Cybenetics Platinum switching efficiency. Under the hood is a single +12 V design with APFC, LLC, most common electrical protections (against over/under voltage, overload, and overheat); and 100% Japanese electrolytic capacitors. A 92 mm fluid dynamic bearing fan is used to cool the PSU, which is tuned to be fanless up to 150 W load, and 35-40% speed between 150-600 W load. Connectors of this fully-modular PSU include a 24-pin ATX, two 4+4 pin EPS, a 16-pin 12VHPWR connector keyed for 450 W, two 6+2 pin PCIe power, eight SATA power, and five legacy connectors. Available now and backed by a 5-year warranty, the SilverStone Extreme 850R Platinum is priced at USD $215.99.

So it's not actually compliant? I assume it isn't being that there's no atx 3.0 labeling next to the PCIe 5 on the box. That's unusual but maybe not. I've heard rumours that atx 3.0 compliance isn't all that easy to meet.
www.silverstonetek.com/en/product/info/power-supplies/Extreme850RPlatinum/It would be irresponsible for us to include a 600W 12VHPWR connector with a 850W power supply as many high end CPUs are now capable of drawing 200W+ all by themselves, leaving only 50W for everything else!
I have a 750W PSU. My CPU is 105 watts. So, I leave for the GFX card around 250 watts and max 2 x 8-pin connectors.

Well, that's a shame, and in fact Silverstone isn't even following this guide:
What a bunch of bs to sell higher wattage PSU's.
The "Buy a PSU rated at twice what you'll actually need" efficiency argument hasn't made much sense since the early 2000s. PSUs today are far more efficient overall than they used to be, across a much wider range of power delivery. :)
As always, buy sensibly. Over-speccing a PSU makes more sense at the low end, where quality differences are more readily apparent. If you're running an extremely high end system, a 100-200W buffer on the high end is sufficient. For as much time as they'll spend near the "sweet spot" of that efficiency curve, they'll spend just as much time on the low end of it during typical idle or desktop usage.
cases like the Hyte Revolt 3 and SilverStone ALTA G1M will take just about any 4090, the only exception might be the galax HOF due to the dumb crown meme screen.
if you are water cooling with a custom block, you can fit a 4090 into any case you want as long as there is enough space for a radiator
