Pstaroth 2000W Mining Power Supply
Pstaroth’s 2000W mining power supply provides a broad connector set, including 24PIN, 4+4PIN, SATA, and multiple PCI-E 6+2PIN cables. It operates over a wide input range (110V-240V) and includes high temperature protection triggered above 50°C to safeguard components. With an approximately 90% conversion efficiency, this unit aims to deliver reliable power for multi-GPU rigs while saving energy where possible.
VTRETU 2000W Mining Power Supply
VTRETU’s 2000W PSU is a 2U form factor designed for 8-GPU mining rigs, supporting 110-264V input with an 80%+ efficiency target. It ships with 12V output capable cords (6+2PIN), and offers high-speed cooling via a 60mm fan running up to 12,000 RPM. It’s positioned for stable voltage delivery and is compatible with various GPUs in mining setups, while noting it’s not suitable for certain ASIC miners.
Antminer APW7 PSU 1800W (Gen Bitmain)
The Antminer APW7 1800W PSU is designed to power popular mining hardware like S9, L3+, Z9 Mini, and D3. It features a robust 1800W output and 10 connectors, with an emphasis on durability in high-heat mining environments. This unit is widely used in established mining rigs for dependable power delivery across multiple GPUs or ASIC configurations.
Bitmain APW7 PSU 1800W (UPC Variant)
Compared to older APW3++ designs, the APW7 1800W version incorporates a conformal coating to protect MOSFETs and joints from moisture and dust. It is built for high-temperature mining environments, with components rated up to 105°C. A single APW7 can power various configurations, including S9i, L3++, D3, V9, X3, E3, or Z9 mini, and ships with five 6-pin PCIe connector pairs (10 total). This makes it flexible for different rig layouts.
HVVH 1600W Silent Gold PSU
HVVH’s 1600W PSU offers 87 Plus Gold efficiency and a 135mm low-noise cooling fan, aiming to balance performance and cooling in mining rigs. It includes a straightforward 110V input setup and a broad 1.5m US plug adapter, making it suitable for US-based mining installations where space and cooling are considerations. It emphasizes genuine specifications and stable operation under load.
RAIDMAX Vortex 700W Power Supply
RaidMax Vortex 700W provides a Bronze-certified efficiency option with ATX and EPS compatibility. While lower wattage than other picks, it may suit smaller, mixed rigs or backup power setups where GPUs are fewer or where budget constraints apply. The 120mm fan helps keep temperatures in check for compact mining builds.
Buying Guide: Key Purchase Considerations
- Wattage and headroom: For 8-GPU rigs, look for 1800W to 2000W units with some reserve for motherboard and other peripherals. Assess total GPU draw and add a buffer for safe operation.
- Connector availability: Ensure enough PCIe 6+2Pin, SATA, and 24-pin connectors to support all GPUs and auxiliary components. Verify cable lengths for your rig layout.
- Efficiency and cooling: Higher efficiency reduces heat output and electricity costs. Favor units with robust cooling fans and low-noise designs if rigs operate continuously.
- Protection features: Over-voltage, over-current, short-circuit protection, and high-temperature shutdown safeguard valuable hardware in harsh mining environments.
- Form factor and compatibility: 2U or standard ATX form factors affect rack placement and airflow. Confirm compatibility with your mining frame and motherboard.
- Durability and temperature rating: Mining environments reach high temperatures. Choose PSUs rated for high-temperature operation and with protective coatings or robust components.
- Brand support and availability: Established brands with readily available replacements reduce downtime. Consider warranty terms and access to support.
- Noise and power quality: Noise levels matter in workspace setups. Look for features that minimize acoustic output while maintaining steady voltage.
- Cost of ownership: Compare price against efficiency, reliability, and expected lifespan to determine true value over time.
