The 12VHPWR connector has been under much scrutiny as of late; in some isolated cases, it overheated and melted. It likely has a lot to do with cable bending too close to the connector and the quality control of these power connectors. We can only assume that NVIDIA has stepped up the validation processor for these connectors. Otherwise, it will cost them a lot of business as opposed to AMD who keeps implementing the old style 6/8-pin connectors. Despite conforming to PCIe Gen 5 specifications, the GeForce RTX 4090 employs a PCIe Gen 4.0 x16 host interface. 

GeForce RTX 4080 is equipped with 16 Gigabytes of GDDR6X memory, which operates at 22.4 Gbps (effective data rate). This provides a substantial amount of volume and bandwidth combined it's 256-bit wide memory bus. With a 320W TGP, we advise a 650 Watt power supply as a minimum. This STRUIX model is allowed a 360W TGP.  Realistically though, we did not hit that value. You're looking at roughly ~300 Watts, which is significantly lower than the Radeon RX 6900X and GeForce RTX 3090. The board partners, however, have more TGP allowance.

The STRIX is significantly larger than the NVIDIA Founders Edition. The card's dimensions are 35.8 x 7 cm (!), weighing 2404 g. The card uses the 12+4 pin ATX 12VHPWR connector, and an adapter cable from 3x PCIe 8-pin is available. This BIOS switch allows you to choose between the standard performance BIOS and the quiet BIOS, which has a more relaxed fan curve. Four slots in your system are required for installation. Three standard DisplayPort 1.4a ports and two HDMI 2.1a ports are provided for display communication (same technology as Ampere). It's a bit of a letdown that NVIDIA did not opt for the new DP 2.1 standard already. The IO panel is an air vent with connectors that will support 8K 60 Hz HDR via a single HDMI cable. Heat pipes connect the various cooling elements to a vapour-chamber plate, which removes heat from the GPU and memory.

Again, the 12VHPWR power connector header (converter cable included that feeds from three 8-pin connectors). Remember, do not bend the cable too close to the connector; try and keep a 3-4cm distance from the bending point. Also, make sure it's pushed in deeply; you'll hear a soft click once mounted properly.  The graphics card generates 320~330 Watts of heat; you will need a PC with a proper intake (front) and vent (rear/top). Small facts; TGP is 360W, GPU Controller MP2888A, controller UP9529QQKF, Phase Count 10+3, Mosfet TDA21570, MOSFET 18+3.
