Smart Digital Control

Built on a powerful digital platform, the Toughpower i1650W lets you monitor wattage, voltage, efficiency, and temperature in real time via the TT RGB PLUS software on desktop or mobile. Stay in control. Stay protected.

Smarter Control, Safer Power.

With real-time monitoring, single/ multi rail mode switching, and Smart Zero Fan control via TT RGB PLUS software, you gain full command over performance, efficiency, and protection.

Smart Monitoring, Flexible Protection

Monitor power usage in real time for PCI-E, CPU, and 12V-2x6 outputs via software, while switching between single and multi rail modes to optimize protection for overclocking or multi GPU setups.

ATX 3.1 Ready

Toughpower i1650W is fully compatible with Intel ATX 3.1 specifications, supporting up to 200% power excursion, reaching 60% efficiency at low load, and meeting all required power supply timing standards.

PCIe Gen 5.1 Ready

Toughpower i1650W comes with native 12V-2x6 (16 pin) connectors to deliver powerful and stable performance, allowing the PSU to support nextgeneration GPUs.

The wattage marked on the 12V-2x6 connector follows Intel's recommended design guideline. With four native 16 pin (12V-2x6) PCIe connectors, the i1650W can support multiple high-wattage PCIe 5.1 graphics cards simultaneously.

Be Smart, Stay Quiet

Featuring an ultra-quiet 140mm fan with Smart Zero Fan technology to provide efficient and silent cooling. Fully modular low-profile cables let users to have cleaner builds and optimize airflow.

High Amperage Single +12V Rail & High-Class Technologies

Powerful single +12V rail can deliver the power you need for the best compatibility. The use of LLC and DC to DC circuit design provides extremely stable operation and enhanced voltage regulation.

Smart Power in the Cloud

Monitor and analyze real time power data across devices with DPS G software. Upload key information to the cloud and easily share reports through mobile or social platforms.

Built-in Industrial Grade Protection

To protect your hardware, Toughpower i1650W is built with industry grade protections: OCP (Over Current Protection), OVP (Over Voltage Protection), UVP (Under Voltage Protection), OPP (Over Power Protection), SCP (Short Circuit Protection), and OTP (Over Temperature Protection).

Fully Modular Low-Profile Cables

Offers users more flexibilities for PSU installation. Low-profile black cables make cable management easier, reduces clutter and increases airflow inside the chassis.

80 PLUS Titanium Certified

80 PLUS Titanium certified, the 1650W model delivers up to 94% energy efficiency, minimizing power loss and heat generation even under full load.
