16GB RDNA 2 graphics card

The Sapphire TOXIC Radeon RX 6900 XT delivers 16GB of GDDR6 memory across a 256-bit interface for 4K gaming and compute workloads. A game clock of 2235 MHz and boost up to 2365 MHz provide strong baseline performance. The One Click TOXIC BOOST feature raises the ceiling to 2425 MHz with a single toggle. Built on the RDNA 2 architecture, it supports DirectX 12 Ultimate and drives up to four displays at 7680 x 4320 resolution.

PCIe 4.0 slot and 850W PSU required

Verify that your motherboard offers a full-length PCI Express 4.0 x16 slot with enough physical clearance for a triple-slot air cooler. The board draws up to 400W and needs two 8-pin plus one 6-pin power connectors from the supply. A minimum 850W unit is specified to handle transient spikes. Ensure the operating system is a 64-bit version of Windows 10, Windows 11 or Linux; Windows 7 and 8.1 are listed but lack full feature support.

TOXIC Tri-X air cooler and triple-display I/O

The Tri-X cooling array uses three fans and a large heatsink to dissipate 400W under load, so case airflow must accommodate exhaust volume. One HDMI 2.1 port and three DisplayPort 1.4 connectors allow mixed monitor setups without adapters. The metal backplate adds rigidity and helps prevent PCB flex during transport or vertical mounting. Refurbished units are tested to meet original thermal and electrical specifications.

Questions about this item

Does the refurbished Sapphire TOXIC Radeon RX 6900 XT 11308-11-20G include the original box, cables or mounting hardware?

As a refurbished unit, the card itself is supplied; original packaging, documentation and accessory cables are not guaranteed.

Should I choose the TOXIC model over a standard RX 6900 XT for the 2425 MHz One Click TOXIC BOOST clock?

The TOXIC edition adds a factory One Click TOXIC BOOST up to 2425 MHz plus Tri-X cooling, giving higher out-of-the-box clocks than reference 2365 MHz boost designs.

Will my 850 W power supply handle the 400 W TDP and the 2 x 8-pin plus 1 x 6-pin connectors on this card?

Yes — the manufacturer specifies a minimum 850 W PSU and the card draws up to 400 W through two 8-pin and one 6-pin connectors, matching that requirement.
