When GALAX revealed their flagship GeForce RTX 3090 Ti HOF OC LAB Edition graphics card, they didn't show off the PCB too much. Japanese overclocker, Duck OC, has acquired his sample of the OC LAB edition and given us a first look at the impressive 28 phases onboard this monster card.

The HOF series has always been the pinnacle of overclocking and only a few other designs are able to match the capabilities of these cards. The GALAX GeForce RTX 3090 Ti HOF OC LAB Edition is also the only other card besides the EVGA GeForce RTX 3090 Ti KINGPIN Hybrid which will feature dual 16-pin connectors for a max theoretical power input of 1200 Watts. The TGP of this specific variant is set to 516W and since the Gen 5 connectors don't allow the card to sip in power through the PCIe interface, a second connector is required to sustain the 516W TGP. You can see the PCB connected to dual 16-pin adapters which lead to six 8-pin connectors.
