Refurbished Radeon RX 7900 XTX 24GB

The XFX Speedster MERC310 is a refurbished graphics card built around the AMD Radeon RX 7900 XTX GPU. It delivers 24GB of GDDR6 memory across a 384-bit interface with 6144 stream processors. The card targets enthusiasts who want high frame rates at 4K resolution in modern titles. A triple-fan cooler manages the 327W thermal design power.

Upgrade path from earlier 7000 Series cards

Moving to this model from a lower-tier Radeon RX 7000 Series card adds 24GB of memory and a 2615 MHz boost clock. The jump is worth it when workloads exceed 16GB VRAM or when 4K gaming demands higher sustained clocks. The PCI Express 4.0 x16 interface matches existing platforms, so no motherboard change is required for the upgrade.

Build fit: power, space and display connectivity

The 344 mm length and 2.9-slot width demand a spacious case and clear airflow path. An 850W power supply is recommended to feed the 327W TDP. One HDMI 2.1 and three DisplayPort 2.1 outputs drive up to four monitors at 7680 x 4320 resolution. The card occupies a single PCIe x16 slot and leaves other expansion slots free.

Questions about this item

Will the 344 mm length and 2.9 slot width fit in my case?

The card measures 344 mm long and occupies 2.9 slots, so verify your chassis clearance and motherboard spacing before ordering.

Which power connectors does the MERC310 cooler require for installation?

Connect two 8 pin PCIe power cables directly from the PSU; using a single daisy chained cable is the step most builders get wrong.

How often should I clean the triple fan heatsink on this 327 W card?

Remove dust from the three fans and fin stack every 6 to 12 months to maintain the thermal headroom needed for the 2615 MHz boost clock.
