NVIDIA RTX 5090 "Blackwell" Could Feature Two 16-pin Power Connectors

The A2000 has a 1200 MHz boost clock, while the 3060ti default boost clock is 1665 MHz.
Almost guaranteed that if you lower your 3060/3060ti clocks to A2000 levels you will obtain similar efficiency figures, minus the inconvenience of the additional PCIe power cable.

Meanwhile, if I wanted 48GB of VRAM at sub-3090 performance, I wouldn't have other choices than spending 5000$ on the A6000, or getting an additional GPU.

while a lot of games will run on mobile grade/perf level, things that most will buy +500$ gpus for wont, like flight/racing sims or FPS, especially when offering increased IQ with things like RT.

and i dont and never will never play online (stream/cloud), short of 2 or 3 games where its about the fun (squad made up from friends not sitting next to each other), unless its a game requires to be online (but still runs on my pc/console).

and i didnt even do consoles anymore myself, as crossplay doesnt require it anymore, and i rather invest same amount in upgrades, vs replacing the whole console every couple years, ignoring it wont (easily) run my older games like fleet command or pinball machines.

If the 5090 is going to be a 600+W card then going double on the power connectors is the sanest thing to do.
The “burning” problem with 4090 connectors is current (A), forget watt. Current flow “creates” heat through wires and connectors without perfect touch of pins because of resistance.

In future going from 12V to 24V will cut current in half = less resistance and heat. It’s simple math to get the same wattage with higher voltage.

This is the reason why many high performance EVs are switching from 400V to 800V. To cut current (A) in half. Wiring was getting thicker and thicker as power was increasing and the risk of fire was getting higher on wire connections in the car.

Of course this is done a lot easier on EVs than PCs. On PCs too many thing have to change for that kind of transition. Won’t be easy but if power keeps growing it will be inevitable.

You going to need a bigger connector

When gamers demand better.

The problem with this line of thought is gamers haven't been nvidias chief money maker for a very long time. In other words: what you think is an afterthought to them, if its relevant at all.

I wouldn't even be surprised with the 5090 comes with 2x 16-pin, even if the Default TDP of the 5090 was 550W and the OC TDP was 600W, it would still put a lot of stress on that small connector...
2x 16-pin seems the right thing to do to avoid some melting issues like with the 4090. Also AIBs will definitely release some variants with 600W+ BIOS so they will definitely need 2x 16-pin connectors.

For the better, especially since 12VHPWR is only overspecced for 610 Watts.

Looking forward to the 6090 That will need this just for the GPUs other half of power.

Dual PSU system with an external 400x400 radiator just for the GPU ^^

But to be real... Whoever buys a GPU for 2000€+ is probably also okay with 600W powerdraw. This is - in gaming realms - pure enthusiast, and if you use it for work, you buy what you need anyway.

Vertically mounted as in using cases with horizontal motherboard placement?

Because using PCIe riser cables have been nothing but problems for many people, often requiring them to choose lower PCIe gen level ("You only loose a couple percent of performance")?

Yes, exactly. Better to spend $25 on a 4.0 riser than risking $1000+ into the trash (or expensive repairs).

Otherwise, one has to be really thorough in looking at a card disassembled to check if it transfers weight to the case through the I/O bracket.

Industry needs regulating to get this under control.

If Nvidia use the sense pins to block GPU powering up with only one cable, then people will be having to buy 1300watt PSUs to use a card that might consume less than half that.
