Hellhound Radeon RX 9070 XT 16GB OC

The PowerColor Hellhound Radeon RX 9070 XT 16GB OC is a graphics card built on AMD RDNA 4 architecture. It targets enthusiasts who want 16GB GDDR6 memory on a 256-Bit bus for 4K gaming and heavy compute workloads. The card uses a PCI Express 5.0 x16 interface and delivers a boost clock of 3010 MHz in OC mode. It fits ATX builds with a 327 mm length and 2.5 slot width.

Sustained load behaviour

Under continuous load the GPU runs at a game clock of 2460 MHz in OC mode while the 20.0 Gbps memory feeds the 4096 stream processors. The triple fan cooler dissipates the 304W thermal design power across the 327 mm board. An 800W power supply feeds the two 8-pin connectors to keep voltages stable during long sessions. The 2.5 slot bracket allows extra airflow around the heatsink fins.

Installation notes

The card occupies 2.5 slots and measures 327 mm long, so verify case clearance before fitting. Two 8-pin power cables must be seated fully to avoid boot failures. The single HDMI 2.1 and three DisplayPort 2.1 outputs support four monitors at up to 7680 x 4320 resolution. Driver installation on a clean OS prevents most detection issues.

Questions about this item

How loud and hot does the triple-fan cooler run when the card draws its 304W TDP all day?

The triple-fan design targets the 304W thermal design power, with separate OC and Silent BIOS profiles that shift the game clock between 2460 MHz and 2400 MHz to balance noise and temperature under sustained load.

What power supply and connectors must my system already have for this 304W card?

An 800W PSU is recommended, and the card requires two 8-pin PCIe power connectors to deliver the 304W TDP.

Will the PCI Express 5.0 x16 interface and 327 mm length work in my older ATX case and motherboard?

The card fits a standard ATX slot at 2.5 slots wide and 327 mm long, and the PCIe 5.0 x16 link is backward compatible with PCIe 4.0 and 3.0 motherboards.
