2000W PSU Gold Power Supply for Mining Rigs - High Output for 8 GPUs

In this review the focus is on a high-power mine chassis power supply designed for multi-GPU mining rigs. The DAFA 2000W PSU delivers up to 2000W at 220V and 1600W at 110V, making it a practical choice for miners who need a dedicated, heavy-duty supply that supports up to eight graphics cards under typical loads. The review highlights its real-world tradeoffs: strong output and extensive connectors, but noticeable fan noise and a short one-month warranty. For builders who prioritize raw power and connector count, this PSU is worth considering.

Key Features

• Dual input power: Switches between 110V and 220V operation so the supply provides 1600W at 110V and up to 2000W at 220V for flexible deployment.
• High connector count: Comes with many outputs including sixteen 6+2P PCIe rails and a 20+4P ATX connector, giving broad compatibility with multi-GPU mining rigs.
• Active PFC: Built-in active power factor correction improves voltage stability and efficiency under sustained mining loads.
• Thermal control: Integrated temperature control adjusts fan speed to manage heat and extend component life during long mining sessions.
• Overload protection: A built-in overload fuse prevents damage by cutting power when the unit is overloaded, improving platform safety.
• Rugged build and packaging: Heavy-duty materials and 2cm cotton packaging reduce shipping damage and improve long-term durability.

Who It's For

This power supply is aimed at cryptocurrency miners and builders running dedicated server-style mining machines who need many PCIe power leads and sustained wattage. It is best for rigs where a reliable high-current supply at 220V will be available, allowing the unit to produce its full 2000W rating and power more high-end cards safely.

It is less suitable for quiet desktop builds, compact cases where airflow is restricted, or users wanting long warranty coverage; the fan is loud under load and the warranty period is limited to one month, so buyers should be prepared for noticeable noise and accept shorter protection.

Pros & Cons

Pros

• High maximum output of 2000W when supplied with 220V, adequate for large GPU arrays.
• Extensive connector set including sixteen 6+2P PCIe leads and multiple SATA/IDE outputs for flexible installations.
• Temperature-controlled fan and internal overload fuse improve safety and component life.
• Active PFC and server-oriented design suit continuous mining workloads.

Cons

• Fan noise is relatively high due to the large airflow required for cooling at high output.
• Only a one month warranty, which is short compared with many other PSUs on the market.

Our Verdict

The DAFA 2000W gold power supply is a value-oriented, high-capacity option for miners who need many PCIe connectors and robust continuous output at 220V; it handles large GPU arrays and includes useful protections, but buyers should accept louder cooling and a short warranty when choosing this unit.

Frequently Asked Questions

How many high-power cards like 3070 or 3080 can this supply run?
At 110V the limit is three of those high-power cards; at 220V the supply can support up to four such cards before risking overload.

Does it include protection against overloads?
Yes, the PSU has a built-in overload fuse that will trip automatically to protect the unit if it is overloaded.

Is this power supply quiet enough for a home office?
No, the fan produces noticeable noise because it is designed for large-volume airflow needed to cool high power output, so it is better suited for dedicated mining spaces.
