After months of rumors, the GALAX RTX 4090 HOF PCB has been spotted confirming that it does indeed feature 2x 16-pin 12VHPWR connectors. GALAX is well known for making graphics cards that set world records and it looks like this next Hall of Fame edition will be no exception. The previous GALAX RTX 3090 HOF was used to set 16 world records in 2021.

The sleek-looking PCB utilizes GALAX’s usual white theme and what appears to be gold display connectors as well. While a single 16-pin 12VHPWR connector can provide up to 600 Watts of power it is doubtful the dual connector design is intended to deliver a full 1200 Watts. More than likely the extra connector is for improved power delivery during extreme overclocking. A 28+4 phase VRM design, another first for the Ada GeForce RTX 4090 cards, can also be seen. GALAX has not yet officially revealed the new card although it could do so soon. The pictures do indicate that it does use the AD102-300 GPU featuring 16384 CUDA cores paired with 24GB of GDDR6X memory.
VideoCardz notes that GALAX often sends these PCBs out to overclockers for testing as it continues to develop the cooler for it. In terms of coolers, GALAX began using a 4-fan design with its Ampere-based graphics cards and has continued to do so with its GALAX GeForce RTX 4090 Serious Gaming 1-Click OC graphics card. It is not known if the GALAX RTX 4090 HOF will feature a similar design or if the company plans to pair it with an AIO, as has been a growing trend among many manufacturers for top-tier power-hungry GPUs in recent years. An LN2 bios switch was also spotted on the PCB which makes sense since the HOF cards are well-known for being overclocked, while using LN2, to set world records.

Genius.
So you need, 8x 8 pin PCIE power connectors for it? Is that even a thing on any currently sold PSUs?
A couple of ideas. An ATX 3.0 with one connector connected to the 16-pin and the other connected via the 4x pin adapter or 2 PSUs. Still though, plain and simple bonkers. I don't think they're out yet but I could see an ATX 3.0 1600-2000 Watt PSU with 2x 16-pin ports.
If you use adapter cables straight from the PSU you only need 2 8 pin per cable

That exceeds the specification for the 8-pin PCIe cable/adapter. The minimum rating is only 150W per 8-pin cable: so for most applications, if you are using a PCIe to HIPWR adapter, you will need 4 PCIe cables to meet the 600W capacity of the HIPWR adapter. So yeah, MadMummy76 is correct -- most people will need 8 PCIe cables. I don't know of any PSU that has 8 cables off the top of my head though that someone might have kicking around...
Now, not saying Denpepe is wrong though -- Corsair here, since they made both the PSU, the cable and the adapter - can oversize on both ends and allow you to safely exceed that. But I wouldn't make the mistake of mixing and matching cables, PSUs, and adapters and think that just because one of them can exceed the spec, that all of them can. You have to size based on the least common denominator...
I suspect if you buy this card, you almost certainly will also be buying a new PSU to go with it, and you could do what Denpepe suggests and get one that minimizes the cable runs.
Only on the PCIe side; most PSU eight-pin cables terminate into two eight-pin PCIe connectors each, which means that they support at least 300W from the PSU connector.
It's not needed. Not for the 4090 cards that hit market, at least, unless you're at 750W or lower, or have an older higher-power unit.
The Galax card above is from a line of high-powered cards. You won't actually be pulling 1600W through one of these, but instead should read the power rating more as 'unlimited'. These cards are primarily for sub-ambient benchmarking.
Actually I just realized my PSU came with 12x 8 pin PCIE connectors, but I don't think this is common. This is a mining psu that was supposed to go directly to miners in bulk, but a shipment has somehow found its way to the retail market in Eastern Europe.
I'd totally forgotten about mining PSUs. A 1600 W one would be perfect for one of these.
