VTRETU 2000W Mining Power Supply
Features: 2000W rated power with 12V output and 8 (6+2) pin cables; 110V-264V input; over 80% efficiency; includes a high-speed 12000 RPM cooling fan. Best for high-demand mining rigs that require multiple GPUs and stable output. Limitations: Not suitable for ASIC miners with specialized protocols. Best for users who need a robust 8-GPU-capable PSU with strong cooling and wide input compatibility.
Pstaroth 2000W Mining Power Supply
Features: 24PIN, 4+4PIN, SATA, multiple PCIe (6+2PIN) connectors; wide 110V-240V operation; high-temperature protection at 50°C to safeguard components; reported conversion rate around 90%. Best for high-widelity rigs that demand ample PCIe power and stable performance under heat. Caution: Check compatibility with motherboard and motherboard-to-PSU wiring when mixing with ASICs.
Bitmain APW7 PSU 1800W
Features: 1800W with 220V input; conformal coating on PCB to resist HV spark discharges; high-temp components rated to 105°C; supports single S9i, L3++, D3, V9, X3, E3 or Z9 mini with five PCIe 6-pin connectors (10 pins total). Best for ASIC-like setups or hybrid rigs that use Bitmain-compatible hardware. Limitation: Not all GPUs will pair with every ASICC-compatible PSU; verify connector availability for your specific hardware.
HVVH 1600W Silent Mining PSU
Features: 1600W with 87+ Gold efficiency; 135mm fan designed for quiet operation while maintaining performance; factory-original specifications with actual data. Best for mid-to-high load rigs where noise and heat management are priorities. Caution: 1.5-meter US plug cable included—verify cable length for your setup and case clearance.
Thermaltake Smart 600W
Features: 600W continuous output at high ambient temperatures; 80 Plus certified with active PFC; supports PCIe connectors; long MTBF. Best for small rigs, starter builds, or as a secondary supply for spillover power tasks. Limitation: 600W may be insufficient for most 6–8 GPU mining rigs, so use as a supplementary supply or choose higher wattage where possible.
Buying Guide: Key Considerations For Mining Rig Power Supplies
What wattage do you actually need? Calculate total GPU draw and reserve 300–400W for motherboard, cores, and fans. For 6–8 GPU rigs, 1500–2100W units are common, with efficient rails to minimize heat and electricity waste.
Efficiency and heat management matter. Look for 80 Plus Gold or better, large fans, and robust thermal components to handle sustained load. A quieter, cooler PSU reduces thermal throttling and extends hardware life.
Connector availability and compatibility. Ensure enough PCIe 6+2 pins and appropriate 24-pin, 4+4-pin, and SATA connections for your motherboard and risers. Some high-wattage units use nonstandard connector counts; verify your rig’s needs before purchase.
Input voltage range. Rigs in regions with variable mains voltage should opt for PSUs rated up to at least 240V input. Wide-range input reduces strain on the PSU and stabilizes output under fluctuating mains conditions.
Thermal protection and reliability. High-temperature protection and conformal coating help resist mining-specific heat and dust exposure. Consider units with rated operation temperatures around 105°C for internal components when possible.
Frequently Asked Questions
- What is the best wattage for an 8-GPU mining rig? Typically between 1500W and 2100W, depending on GPU models and overclocking. Aim to leave headroom for the motherboard and peripherals.
- Should I choose a 1800W or 2000W PSU? A 2000W unit provides more headroom for high-power GPUs and additional risers; an 1800W unit can be sufficient for moderate rigs but leaves less margin for stability under peak loads.
- Is a dedicated mining PSU necessary? For multi-GPU rigs, dedicated mining PSUs with sufficient PCIe connectors and stable rails are recommended over standard consumer power supplies.
- How important is efficiency in mining PSUs? Higher efficiency reduces heat output and electricity costs, improving long-term reliability in sustained mining environments.
- Can I mix ASIC and GPU hardware on the same PSU? Compatibility varies; check connector counts and voltages. Some APW7-based units are designed for ASICs and may not perfectly support GPU rigs without adapters or modifications.
- What is the risk of overheating a mining PSU? Excessive heat can shorten lifespan and cause protection shutoffs; ensure adequate intake and exhaust, plus proper ventilation in the rig enclosure.
