It’s been quite some time since we first saw the leaked prototype design of the RTX 3080 and the most recent leaked design of the RTX 3090 shows that the card is much longer and wider than what we’ve initially anticipated.

The new photo of the upcoming GeForce RTX 3090 was posted by Twitter user GarnetSunset, with the card compared next to a GeForce RTX 2080 to show the difference in size. The RTX 3090 features a full black design instead of the usual black/silver design from the earlier leaks, but the 3-slot design might only be available on the RTX 3090.

Unlike the dual-fans design on the RTX 20 series Founders Edition cards, the RTX 3090 is equipped with a gigantic heatsink and a larger cooling fan on each side of the card. The cooling performance of the new heatsink design still remains unknown but if NVIDIA were to slap a heatsink of this size on the RTX 3090, we are open to the idea that the rumored /speculated high TDP rating might be true.

NVIDIA has yet to reveal any information on its upcoming RTX 30 series graphics cards but it’s rumored that NVIDIA will be announcing/launch these new GPUs later on September 1st. As for the curious ones, we’ve compiled a list of the possible specifications as speculated by TechPowerUp for your reference. Do note that these are not the official specifications of the upcoming RTX 30 series cards and as always, one should take leaks and speculations like these with a grain of salt.

New 12-pin PCIe Power Connector?

Apart from the high power requirement, fcpowerup reported that the new RTX 30 series cards will also be using a new type 12-pin PCIe power connector but Gamers Nexus has confirmed that it’s highly unlikely that you’ll need to get a new PSU with 12-pin PCIe power connector for the RTX 30 series cards. The 12-pin connector design will be strictly for OEM partners and system integrators, which is pretty much the same for the OEM and SI focused ATX12VO power supply design announced earlier this year.

Gamers Nexus also reported that the power supply manufacturers are working on the tooling and molds for the new 12-pin connector but it’s unknown just how widespread will the new connector be in the future. Just in case if NVIDIA decided to go with the new 12-pin PCIe power connector for its new RTX 30 series Founders Edition cards, we hope that they will at least provide an adapter/converter for existing power supplies that only comes with 6-pin and 6+2-pin PCIe power connectors.

NVIDIA GeForce RTX 3090 12 pin PCIe Molex Micro Fit

Update

Earlier today, Seasonic teased the new 12-pin PCIe Molex Micro-Fit 3.0 Connector which they’ve prepared for the upcoming GeForce RTX 30 series cards. Based on the label on the box, we can see that the connector is pretty similar to the Dual Molex to PCIe we have from the early days but this time it’s a Dual 8-pin (6+2) to 12-pin PCIe Molex Micro-Fit 3.0.

The description on the label stated that it is recommended to use an ‘850W or higher power supply’ for this connector, which suggests the RTX 30 series cards might be even more power-hungry that what others have speculated?
