Introduction
Assembling your own mining rig can be both rewarding and cost-effective. This guide walks you through building a high-performance mining machine using carefully selected components, optimized for cryptocurrency mining while keeping costs around $4,000.
Component Breakdown & Assembly
1. Motherboard Selection
- Model: H111 SSL by Supermicro
Key Features:
- 6 PCIe slots for multi-GPU setups
- Triple Ethernet ports (including 1 management port)
- Supports 8 SATA devices + M.2 SSD
2. Installing Core Hardware
- CPU: Single processor (exact model TBD based on mining needs)
- RAM: 1 stick (ensure proper alignment with the slot’s notch)
Cooling:
- Budget-friendly $20 fan with pre-applied thermal paste
- Installation tip: Tighten screws diagonally for even pressure
3. Power & Testing
- Initial Test: Connect only CPU + RAM to verify functionality.
- PSU Installation: Secure a high-wattage power supply (recommended: 80+ Gold).
- Interfaces: Hook up USB 2.0/3.0, display ports, and storage drives.
4. GPU Setup
Graphics Cards:
- NVIDIA 3070 Ti (8-pin power)
- NVIDIA 4080 (12-pin, requires adapter)
Installation:
- Use manufacturer-provided adapters for clean cable management.
- Secure GPUs to the open-frame case (optimized for airflow).
5. Final Assembly
- Case: Open-air design (purchased via Taobao)
- Power Switch: Manually connect if the case lacks one.
- Boot Test: Confirm both GPUs are detected (~150W power draw).
Performance & Mining
- Stability: CPU temps remain low; GPUs hash efficiently.
- Use Case: Ideal for altcoin mining (e.g., Ethereum Classic, Ravencoin).
