ASRock Arc A770 8GB graphics card

The ASRock Phantom Gaming Arc A770 delivers 8GB of GDDR6 memory on a 256-bit interface with a core clock of 2200 MHz. It connects through a PCI Express 4.0 x16 slot and occupies 2.8 slots in an ATX chassis. The card measures 305 mm long and draws up to 225W, requiring a 700W power supply and two 8-pin connectors.

Upgrade from older 8GB GPUs on PCIe 3.0

Moving to this card adds PCIe 4.0 bandwidth, DisplayPort 2.0 outputs and DirectX 12 Ultimate support for modern titles. The jump is worthwhile when your current board supports Resizable BAR and your power supply meets the 700W recommendation. Without Resizable BAR enabled, the Intel Arc architecture cannot reach its intended performance level.

Practical limits of PCIe 4.0 x16 and DisplayPort 2.0

The x16 link provides ample throughput for the Arc A770, so the interface is not a bottleneck at 1440p or 4K. DisplayPort 2.0 ports can drive 7680 x 4320 resolution, but cable quality and monitor capabilities often limit real-world refresh rates at that pixel count. HDMI 2.1 supports the same maximum resolution for a single display.

Questions about this item

Will the 305 mm length and 2.8 slot width fit in my ATX case?

The card measures 305 x 131 x 56 mm and occupies 2.8 slots, so verify your case clearance and motherboard spacing before purchase.

Which power connectors must I plug in for the 225W TDP?

Connect both 8-pin PCIe power cables from a 700W or larger PSU; missing either connector will prevent the card from starting.

How often should I clean the triple-fan cooler to keep temperatures stable?

Blow dust from the heatsink and fan blades every three to six months; thermal paste replacement is only needed if temperatures rise unusually after years of use.
