Building a high-performance Ethereum (ETH) mining rig requires careful selection of reliable and efficient components. Whether you're scaling up from a small home setup or deploying multiple rigs for commercial mining, choosing the right frame, power supply, motherboard, and accessories is crucial to maximizing hash rates, minimizing downtime, and ensuring long-term profitability.
This guide explores top-tier mining rig components available in 2025, focusing on durability, scalability, and compatibility with modern GPU configurations. We'll break down essential parts—from open-air mining frames to robust power supplies—and help you assemble a system optimized for ETH and other GPU-mineable cryptocurrencies like Ravencoin (RVN), Ethereum Classic (ETC), and Zcash (ZEC).
Key Components of a Complete ETH Mining Rig
A successful mining operation isn't just about GPUs—it's about integration. Here are the core building blocks:
Mining Frames & Cases
Mining frames provide structural support for multiple GPUs while ensuring optimal airflow and easy access for maintenance. Most are open-air designs made from steel or aluminum for durability and heat dissipation.
- 8GPU Steel Frame: A budget-friendly option at $35.99, ideal for beginners. Supports dual power supplies and offers fast delivery.
- 12GPU Steel Frame (Dual PSU Support): Priced at $52.99, this model allows room for expansion and enhanced power redundancy.
- The Sluice V2 12GPU Frame: A popular stackable design priced at $41.99 (down from $53.99), offering excellent value for scalable setups.
- V3C Aluminum Frames (6-GPU & 8-GPU): Premium builds with fan mounts and corrosion-resistant materials, priced between $129.99 and $179.99.

Power Supply Units (PSUs) for High-Load Mining
Stable power delivery is non-negotiable in crypto mining. Look for units rated at 2000W with active PFC and multiple PCIe connectors.
- ABSKY 2000W Mining PSU: $75.90 – Includes adapter cables and supports up to 8 GPUs.
- VTRETU 2000W 2U PSU: $99.99 – Features a powerful 12,000 RPM cooling fan and universal voltage input (110V–264V).
- ALEO-Compatible 2000W PSU: $85.80 – Designed specifically for ETH mining rigs with efficient energy conversion.
Ensure your PSU can handle peak loads without throttling—undervoltage can damage GPUs over time.
Motherboards & Riser Cables
Specialized motherboards like the ASUS B250 Mining Expert support up to 19 GPUs via PCIe slots. The DISPRA9524 Gaming Motherboard, priced at $149, supports 12 PCIe risers and DDR4 memory, making it ideal for multi-GPU configurations.
PCIe riser cables (e.g., 6-pack for $25.99) connect GPUs to the motherboard and should be high-quality to prevent signal loss or short circuits.
Pre-Built Mining Systems: Fast Track Your Setup
For users who want to skip assembly, complete pre-built mining servers are available:
- SUOHUI 8-GPU Mining Server: $499 – Includes motherboard, 1800W PSU, 8 cooling fans, and 4GB RAM (GPUs not included).
- VTRETU Complete Miner with Windows 10: $499 – Comes fully equipped with OS, CPU, SSD, and support for ETC, LTC, Monero, and Ravencoin mining.
These systems reduce setup time and are tested for stability—ideal for users prioritizing convenience over customization.
Frequently Asked Questions (FAQ)
Can I still mine Ethereum in 2025?
No, Ethereum transitioned to proof-of-stake in 2022 and no longer supports GPU mining. However, many forks and alternative coins like Ethereum Fair (ETF), EthereumPoW (ETHW), and Ravencoin (RVN) remain mineable using similar hardware.
What is the best GPU for ETH-like mining?
GPUs such as the NVIDIA RTX 3060 Ti, RTX 3070, AMD RX 6700 XT, and RX 6800 are highly effective for mining ETH-fork tokens due to their high memory bandwidth and efficiency ratios.
How much power does an 8-GPU rig consume?
An average 8-GPU rig consumes between 1,200W and 1,600W under load. With electricity at $0.12/kWh, operational costs range from $3.50 to $4.60 per day.
Do I need a dedicated motherboard for mining?
Yes. Standard motherboards support only one or two GPUs. Mining-specific boards offer multiple PCIe x1 slots for riser cables and better BIOS support for multi-GPU detection.
Are aluminum frames better than steel?
Aluminum frames are lighter and resist rust but may be less rigid. Steel frames offer superior durability and lower cost—ideal for fixed installations.
How do I cool my mining rig effectively?
Use open-air frames with mounted fans (8+ recommended), ensure proper spacing between rigs, and place them in well-ventilated areas. Consider adding external exhaust fans or dedicated cooling rooms for large-scale operations.

Final Tips for Building a Profitable Mining Rig
- Prioritize Compatibility: Ensure your PSU voltage matches your region’s power grid.
- Buy from Reputable Sellers: Many top products come from small businesses with strong customer reviews.
- Plan for Scalability: Choose stackable frames and modular PSUs so you can expand later.
- Monitor Efficiency: Use software tools to track power draw, temperature, and hash rate per GPU.
As the crypto landscape evolves, repurposing old ETH mining hardware for newer proof-of-work chains remains a viable strategy. With the right components, your rig can continue generating returns well beyond Ethereum’s mining era.
