12GB GDDR6 Radeon RX 7700 XT
The PowerColor Hellhound RX7700XT 12G-L/OC is a 12GB graphics card built on the AMD Radeon RX 7000 Series architecture. It delivers 3456 Stream Processors and a 192-Bit memory interface for 1440p gaming and content creation workloads. The card connects through a PCI Express 4.0 x16 slot and supports up to four displays via one HDMI 2.1 and three DisplayPort 2.1 outputs. Maximum digital resolution reaches 7680 x 4320.
2.5-slot ATX card with 750W PSU requirement
Before ordering, verify that your case can accommodate a 332 mm long, 2.5-slot ATX form factor and that your power supply meets the 750W recommendation. The board draws up to 245W and requires sufficient PCIe power connectors from the PSU. Ensure the motherboard provides a full-size PCI Express 4.0 x16 slot and that airflow around the triple-fan cooler is not restricted by adjacent components or cables.
Sustained load on 245W triple-fan design
Under continuous load the GPU operates at its 245W thermal design power with the triple-fan cooler managing heat across extended sessions. Core frequency settles around the 2276 MHz game clock rather than the 2599 MHz boost clock, providing stable frame pacing in long gaming or render runs. The 12GB GDDR6 buffer and 192-Bit bus maintain consistent throughput for texture-heavy workloads without throttling.

Questions sur cet article
What cables or adapters come with the PowerColor Hellhound RX7700XT 12G-L/OC, and do I need to buy a separate power cable?
The card uses PCI Express 4.0 x16 and draws up to 245W, so a 750W power supply with the required PCIe connectors must be provided separately; no cables are included in the box.
Should I choose this 12GB 192-Bit GDDR6 model or a different capacity for 1440p gaming?
The 12GB 192-Bit GDDR6 frame buffer is sized for high-refresh 1440p and entry 4K workloads, matching the 3456 Stream Processors and Boost Clock of 2599 MHz on this Hellhound SKU.
What does the 2599 MHz Boost Clock actually deliver once the card is installed in my system?
In typical gaming loads the GPU will sustain speeds near the 2276 MHz Game Clock, while the 2599 MHz Boost Clock represents the peak frequency reached under light or burst workloads within the 245W power limit.
