Refurbished Phantom Gaming RX 7900 XT

The ASRock Phantom Gaming Radeon RX 7900 XT PG 20GO is a refurbished graphics card built on the AMD Radeon RX 7000 Series architecture. It delivers a Game Clock of 2075 MHz and a Boost Clock of 2450 MHz across 5376 Stream Processors. The 20GB GDDR6 frame buffer connects through a 320-Bit interface and the board plugs into a PCI Express 4.0 slot.

Ideal for 4K high-refresh gaming.

This card suits builders targeting 4K resolution at high frame rates who have a 750W power supply and room for a 330 mm long, 2.8 Slot thick ATX board. It requires two 8-Pin power connectors and moves 300W of heat through a Triple Fans cooler. Small-form-factor cases or PSUs below the recommended wattage should look at a smaller model.

20GB GDDR6 on 320-Bit bus decides fit

The single specification that determines whether this is the right part is the 20GB GDDR6 memory paired with a 320-Bit bus. That combination sets the bandwidth ceiling for 4K and 7680 x 4320 workloads and cannot be changed by driver updates or overclocking.

Questions about this item

What case clearance does the 330 mm length and 2.8 slot width need?

The card measures 330 mm long and occupies 2.8 slots, so the chassis must provide at least that much length and vertical space for the triple-fan cooler.

How do I connect the two 8-pin power plugs and what mistake should I avoid?

Plug both 8-pin connectors from the PSU directly into the card; do not use a single cable with a daisy-chained second head, as that can starve the 300 W board.

When should I clean or replace the thermal paste on the Phantom Gaming 3X cooler?

Re-paste only if GPU temperatures rise noticeably after a few years; otherwise routine dust removal from the three fans and fin stack is sufficient.
