As cryptocurrency mining continues to evolve, selecting the right power supply is crucial for building efficient and reliable mining rigs. In 2026, semi modular power supplies remain a popular choice among miners due to their balance of flexibility, affordability, and performance. This article explores the top semi modular power supplies available this year, helping miners make informed decisions for their setups.
What Are Semi Modular Power Supplies?
Semi modular power supplies feature a combination of fixed and detachable cables. They typically have essential cables permanently attached, such as the 24-pin motherboard connector and CPU power, while other cables like PCIe and SATA are modular. This design offers a good balance between ease of installation and cable management, making them ideal for mining rigs where airflow and space are critical.
Key Features to Consider in 2026
- Power Capacity: Most mining rigs require power supplies between 750W to 1600W, depending on the number of GPUs.
- Efficiency Rating: Look for 80 PLUS Gold or higher for optimal energy savings and reduced heat.
- Build Quality: Durable components ensure longevity under continuous operation.
- Cabling: Adequate modular cables for all components and future upgrades.
- Cooling: Effective cooling solutions prevent overheating during extended mining sessions.
