What the ZOTAC RTX 4070 Twin Edge OC delivers

This refurbished graphics card uses the Ada Lovelace architecture with 12GB of GDDR6X memory on a 192-bit bus. It connects through a PCI Express 4.0 x16 slot and reaches a boost clock of 2490 MHz. The board fits a standard ATX form factor at 226 mm long and occupies 2.2 slots.

Moving up from an older GPU

The 4070 replaces cards that lack DLSS 3 frame generation and the efficiency gains of the 40 series. The jump is worth it when your current GPU cannot drive 4K at playable frame rates or when you need the 21 Gbps memory speed for modern texture workloads. A 600W power supply and one 8-pin connector are required.

Compatibility checklist before ordering

Verify that your case clears 226 mm of length and 2.2 slots of width for the dual-fan cooler. Confirm the power supply provides 600W and an available 8-pin PCIe connector. Ensure the motherboard has a PCI Express 4.0 x16 slot and that your display uses HDMI 2.1a or DisplayPort 1.4a for the 7680 x 4320 maximum resolution.

Questions about this item

Will the 226 mm length and 2.2-slot width fit in my mid-tower case?

The card measures 226 mm long and occupies 2.2 slots, so verify your case clearance and motherboard spacing before ordering.

Does the single 8-pin power connector plug straight in, or do I need an adapter?

It uses one 8-pin connector directly from the PSU; ensure your power supply has a native 8-pin PCIe cable rather than a 6+2 adapter.

How often should I clean the twin 90 mm fans on the IceStorm 2.0 cooler?

Remove dust from the two 90 mm fans every 6–12 months using compressed air to keep the FREEZE Fan Stop and Active Fan Control working correctly.
