Thermaltake Toughpower GX2 600W
The Thermaltake Toughpower GX2 600W PSU is a Gold-certified ATX 12V V2.4 unit with non-modular cables. It’s designed for reliable continuous power delivery and is optimized for highly efficient operation, supporting C6/C7 sleep states for energy savings. While non-modular, its compact design and solid cooling make it a practical option for smaller mining rigs where budget constraints or space limitations apply. It delivers steady power for mid-range GPU mining configurations.
Features include 80 Plus Gold efficiency, a 120mm cooling fan, and a straightforward, durable build. It is suitable for miners who need a dependable power backbone without the extra cost of modular cabling. The PSU’s stability and simple setup can help reduce maintenance in compact frames and entry-level mining deployments.
be quiet! Pure Power 12 M 1200W
The be quiet! Pure Power 12 M 1200W modular PSU is built for high-demand systems with ATX 3.1 and PCIe 5.0 compatibility, including a 12VHPWR cable. It combines top-tier efficiency (up to 93% in suitable loads) with robust power delivery and a silent 120mm fan. The dual 12V rails and very high output capacity make it suitable for miners running power-hungry GPUs or compute nodes. This unit’s quiet operation helps manage acoustics in home mining setups and small offices.
Key strengths are efficiency, future-proof PCIe 5.0/ATX 3.1 support, and reliable power stability under transient loads. It’s designed to deliver a steady stream of 1200W, which can support multi-GPU rigs, and it includes a reliable cooling solution to maintain performance during extended mining runs.
POWER MINING Bitaxe Gamma 601 ASIC Miner PSU
The POWER MINING Bitaxe Gamma 601 is a complete mining solution including a 1.1 TH/s ASIC miner with a BM1370 chip and included power supply. It emphasizes energy efficiency with a reported 18W power draw per 1.1 TH/s, which aligns with compact, home-based mining goals. This unit is Europe-made, with open-source AxeOS and Wi-Fi capabilities, designed for straightforward operation in hobbyist or small office mining environments.
Considerations include the integrated miner and PSU pairing, the European build quality, and the practical power-to-hash ratio. It’s suitable for miners seeking a compact, self-contained mining solution rather than assembling a separate PSU and mining rig from scratch.
SilverStone Dual 24pin Power Supply Adapter
The SilverStone Dual 24pin Power Supply Adapter enables starting two power supplies on a single motherboard, a practical accessory for mining rigs that may benefit from distributed power sources or redundancy. It uses dual 24pin female connectors and a single 24pin male connector to facilitate parallel PSU operation. This is particularly useful in larger mining frames or setups where uptime is critical and multiple PSUs are deployed to meet demand or ensure redundancy.
Buying Guide
Power supply considerations for mining should balance wattage headroom, efficiency, connector availability, and cooling. Key factors include:
- Wattage headroom: Choose a unit with more continuous wattage than your peak draw to handle spikes without voltage drops. For multi-GPU rigs, aim higher than your total estimated load.
- Efficiency rating: 80 Plus Gold or better reduces heat and electricity costs over long runtimes, which matters for mining economics.
- Modularity: Fully modular units simplify cable management in crowded mining frames, improving airflow and cooling.
- Connectivity: Ensure PCIe 5.x or PCIe Gen 5 compatibility if you plan to use newer GPUs, and check for 12V-2×6 pin or 12VHPWR support for future GPUs.
- Cooling and noise: Larger, quieter fans and robust airflow help extend component life in hot environments. Consider units with silent or low-noise operation.
- Build quality and protection: Look for solid over-voltage, over-current, and short-circuit protection, plus solid capacitors and a reputable warranty.
- Redundancy options: Accessories like dual-PSU adapters can be valuable in larger mining setups where uptime matters.
Bottom line: for small to mid-size rigs, a high-quality 850W–1200W Gold-rated modular PSU from a reputable brand provides stability and efficiency. For larger or more demanding setups, 1600W units or multi-PSU configurations with reliable interconnects and cooling are recommended to maintain consistent performance and prevent power bottlenecks.
