The data notes an incompatible variant exists for some RX 6800 XT Red Dragon boards, so check your circuit board carefully. It is not recommended for use with other video cards. If you need a block for a different GPU brand or model, this part will not fit. Additionally, if you prefer air cooling solutions, this water block is not suitable for your setup.
Verdict: This block offers a complete, spec-focused solution for compatible PowerColor cards. It provides the necessary hardware for a clean, water-cooled build with minimal extra purchases.
Key specs explained
Lighting Type: A-RGB (RBW)
This stands for Addressable RGB with a 5-volt pin. It lets you control each LED individually via motherboard software. You can create complex patterns or sync colors with other components. Standard RGB only shifts the entire strip one color at a time. Check your motherboard headers to ensure they support 5V addressable lighting before purchasing this block.
width: 7.11 inches
This dimension measures the block from side to side across the GPU. It helps you determine if the block fits within your case width limits or if it will interfere with nearby components like RAM or PCIe slots. Compare this width to your current air cooler or other water blocks to ensure proper clearance inside your chassis.
height: 2.05 inches
This is the vertical thickness of the block from the PCB to the top of the acrylic. It determines how much vertical space you need above the graphics card. If your case has tight clearance for the GPU, this height ensures the block will not hit the case side panel or other nearby hardware during installation.
length: 11.8 inches
This measures the block from the front to the back of the card. It confirms the block covers the entire length of the supported PowerColor cards. This full coverage ensures all critical VRMs and memory modules are cooled. Verify this length against your specific GPU model to ensure the block aligns correctly with the card edges.
weight: 6.1 pounds
This is the total weight of the block, backplate, and hardware. A heavy block can stress the GPU PCB and PCIe slot over time. Ensure your case has adequate support for the graphics card to prevent sagging. Compare this weight to lighter acrylic-only blocks to understand the structural load your motherboard and case must support.
Design and Build Quality
According to the listing, the block uses a full acrylic top and a high-purity purple copper cold plate. This copper grade offers excellent thermal conductivity, second only to silver in these material categories. The design prioritizes rapid heat absorption and exchange. This construction aims to lower GPU temperatures more effectively than air cooling solutions. The unit includes a matching backplate for structural support and additional heat dissipation. All necessary mounting hardware and thermal interface materials are included in the package. You do not need to source separate parts for installation.
The physical dimensions are 11.8 inches long, 7.11 inches wide, and 2.05 inches high. The total weight is 6.1 pounds. This substantial mass suggests a robust build designed to handle the thermal load of high-end graphics cards. The block is engineered specifically for PowerColor Radeon RX 6800 XT and RX 6900 XT models. It is compatible with the Red Devil and Red Dragon variants. You must verify your circuit board against the provided design images before purchase, as incompatible variants exist. Using this block with other video cards is not recommended.
Lighting is provided by an installed A-RGB strip with a 5-volt RBW pin. This allows for individual LED control via motherboard software. The components use industry-standard threads and materials to ensure compatibility with other water-cooling parts. The finish and materials are chosen to integrate seamlessly into custom loop builds. The design focuses on straightforward installation and reliable performance within a closed-loop system.
Setup and Everyday Use
Installation targets specific PowerColor Radeon RX 6900 XT Red Devil and RX 6800 XT Red Devil cards. You must verify your circuit board matches the gallery design before purchasing, as incompatible variants exist. The package includes the GPU block, backplate, all mounting hardware, thermal paste, pads, and an installed A-RGB LED strip. You do not need to buy extra parts to begin cooling your GPU.
The block uses industry-standard materials and thread sizes. This ensures it connects correctly with your existing water-cooling components. The fit relies on precise alignment with the card’s mounting points. The 11.8-inch length and 7.11-inch width cover the full GPU area. The 2.05-inch height accommodates the cold plate and acrylic top. The 6.1-pound weight suggests a sturdy build that requires secure mounting to prevent strain on the PCIe slot.
Daily use involves managing the A-RGB lighting. The strip uses 5-volt RBW protocol. You control each LED individually through your motherboard’s software. This allows for complex patterns or color syncing with other system components. The cooling performance depends on your loop’s layout and capacity. The block absorbs heat quickly, aiming for lower temperatures than air cooling. However, actual temperature results vary based on your specific pump, radiator, and fluid flow rate. Ensure your loop is leak-tested before powering on. The included one-year warranty covers manufacturing defects. Tyler Direct provides US-based support for compatibility questions.
Before You Buy This Block
You are adding a custom component to your loop, so you must verify your tubing fittings match the block’s ports. The listing notes industry-standard threads, but you should confirm your specific connector style before connecting. You will also need to ensure your coolant is compatible with the acrylic and copper materials to prevent corrosion or clouding over time. Since this block replaces the stock cooler, you must remove the original shroud and fan assembly. This process requires careful handling of the GPU and the new mounting hardware. The included thermal pads must align perfectly with your specific PowerColor variant. Incompatible circuit boards exist, so checking the gallery images is essential. This product fits into the broader category of high-performance GPU cooling, offering lower temperatures than air solutions. You should plan your loop layout to accommodate the 11.8-inch length and 6.1-pound weight. Proper installation ensures stable temperatures and sustained boost clocks during heavy workloads.
Check before you buy
- Verify your PowerColor card model matches the supported variants exactly.
- Check your tubing fittings match the block's industry-standard threads.
- Ensure your coolant is safe for acrylic and copper components.
- Confirm the circuit board design matches the gallery images provided.
