GIGABYTE RTX 3070 Gaming OC 8GB

This GIGABYTE GeForce RTX 3070 Gaming OC graphics card targets gamers and creators who need strong 1440p performance. It ships with 8GB of GDDR6 memory across a 256-bit interface and connects via PCI Express 4.0. The GPU runs at a 1815 MHz core clock and packs 5888 CUDA cores for heavy compute tasks.

Sustained load behaviour

Under continuous load the card draws up to 220W through one 6-pin and one 8-pin power connector, so a 650W supply is recommended. The WINDFORCE 3X cooler uses alternate spinning fans to keep airflow steady during long sessions. Drivers expose the 2nd generation RT cores and 3rd generation Tensor cores for supported workloads.

Thermals noise and power

The triple-fan design and metal backplate help dissipate heat while adding structural rigidity. Fan curves stay moderate in typical gaming scenarios, keeping acoustics low inside an ATX case. The 286 mm length fits most standard chassis without clearance issues. Power draw remains close to the rated 220W during normal operation.

Questions about this item

How loud and hot does the WINDFORCE 3X cooler run when the card draws its 220W TDP all day?

The WINDFORCE 3X system uses three alternate-spinning fans and a metal back-plate to move heat away from the GPU while it operates at the rated 220W thermal design power.

Which power connectors must my PSU provide for the 650W recommended supply to feed this card?

The board requires one 6-pin and one 8-pin PCIe power connector from the power supply.

Will the PCI Express 4.0 interface work at full speed in my older PCIe 3.0 motherboard slot?

Yes, the card is backward compatible and will run at PCIe 3.0 speeds when installed in a PCIe 3.0 slot.
