Hellhound Spectral White 16 GB GPU
The PowerColor RX7800XT 16G-L/OC/WHITE is a refurbished AMD Radeon RX 7800 XT graphics card built for 1440p gaming. It carries 16 GB of GDDR6 memory across a 256-bit bus and connects through a PCI Express 4.0 interface. The white Hellhound shroud fits ATX cases with a 333 mm length limit and occupies 2.5 slots.
Dual BIOS OC and Silent modes
Two firmware profiles let you choose between a 2520 MHz boost clock in OC mode or a 2430 MHz boost in Silent mode. Game clocks sit at 2213 MHz and 2124 MHz respectively. The jump is worth it when you want higher frame rates in demanding titles without manually tuning voltages or fan curves.
750 W PSU and dual 8-pin power
The board draws power through two 8-pin connectors and the manufacturer recommends a 750 W supply. Under sustained load the 3840 stream processors and 19500 MHz effective memory clock maintain stable throughput for extended sessions. Output options include one HDMI 2.1 and three DisplayPort 2.1 connectors for up to four displays.

Questions about this item
Will the 333 mm length and 2.5-slot width of this PowerColor Hellhound Spectral White fit my case?
The card measures 333 mm long and occupies 2.5 slots. Measure the clear space from your motherboard PCIe slot to the front panel or any radiator, and confirm the case specification lists at least 333 mm GPU clearance and room for a 2.5-slot card.
What power connectors does the RX 7800 XT need and which BIOS switch should I set before closing the case?
Connect both 8-pin PCIe power cables from a 750 W or larger PSU. The card ships with a dual BIOS; the default OC position runs at 2520 MHz boost, while the Silent position runs at 2430 MHz boost. Set the switch before you secure the bracket.
How often should I clean the fans and when might the thermal paste on the Radeon RX 7800 XT need replacement?
Dust the three axial fans every few months with compressed air to keep airflow over the heatsink. Thermal paste on the GPU die typically lasts several years; plan to re-paste only if temperatures rise noticeably under load after that period.
