NVIDIA made a big deal of its new 12-pin connector on the lead-up to the release of the RTX 30 series, which it claimed would be compatible with PCIe 8-pin cables. Corsair and other OEMs are preparing to release 12-pin PSUs for those who want the cleanest looking set-up, but NVIDIA made no mention of its new connector at last week's launch. Likewise, the few official renders of the RTX 3080 Founders Edition that have been published do not confirm the presence of a 12-pin connector. One does show the card's power connector, but not the full width of it.
Indeed, a cursory check of the specifications of the RTX 3080 Founders Edition reveals that the card requires two PCIe 8-pin connectors. Conversely, NVIDIA refers to the card as having a "new 12-pin power connector" in one graphic, albeit it has hidden this text somewhat.
Thankfully, Digital Foundry has cleared up the matter. At 2:55 minutes into its RTX 3080 hands-on video, Digital Foundry shows a close-up of the 12-pin connector, which we have included above. However, add-in-board partners (AIBs) will not be using the new connector, as Tweaktown suggested last month. We can confirm that at least KFA2, inno3D, MSI and Zotac have gone with two 8-pin connectors on their custom RTX 3080 cards, which begs the question of why NVIDIA created the 12-pin connector in the first place. Perhaps, NVIDIA will make the 12-pin power connector mandatory for future cards, but we fail to understand the fragmentation with its Ampere generation.
