GUNNIR Arc A770 Photon 8G OC
The GUNNIR Intel Arc A770 Photon 8G OC is a PCIe 4.0 graphics card built for 1440p gaming and AV1 content creation. It pairs 4096 stream processors across 32 Xe cores with 8GB of 256-bit GDDR6 memory running at 16 Gbps. A factory overclock pushes the maximum GPU frequency to 2400 MHz for higher sustained clocks in demanding titles.
Sustained load behaviour at 195W PL1
Under continuous load the card operates at a 195W processor base power limit with a 6+4 phase power delivery fed by dual 8-pin connectors. The 512 GB/s memory bandwidth and 2400 MHz boost clock are maintained through extended sessions thanks to the triple 90mm fan cooler moving air across a full-length heatsink. DirectX 12 Ultimate and XeSS support keep frame rates stable during long rendering or gaming workloads.
Thermals noise and 285W total board power
The total board power reaches 285W under typical gaming loads while the triple-fan array keeps core temperatures controlled without excessive acoustic output. Idle and light-use scenarios benefit from semi-passive fan stop behaviour common to this cooler design. Three DisplayPort 2.0 outputs and one HDMI 2.0 port drive displays up to 7680 x 4320 resolution for multi-monitor productivity setups.

Questions about this item
How loud and hot does the triple-fan cooler run when the card draws 285 W all day?
The three 90 mm fans and 6+4 power phases are built to dissipate the 285 W total board power, so temperatures and noise stay controlled under sustained load.
My power supply only has a single 8-pin cable — will the dual 8-pin connectors on this card work?
The board requires two separate 8-pin connectors; a single cable with a daisy-chain pigtail cannot deliver the 285 W safely, so a PSU with two native 8-pin leads is needed.
Will the PCIe 4.0 x16 interface run at full speed on my older PCIe 3.0 motherboard?
The card is backward compatible with PCIe 3.0 slots; it will operate at 3.0 speeds with minimal impact on the 512 GB/s memory bandwidth for most workloads.
