Power supply unit ASROCK Taichi TC-1650T 1650 W 20+4 pin ATX 80 PLUS Titanium, 135 mm fan, Black

The ASROCK Taichi TC-1650T is a 1650 W ATX power supply designed for high-performance desktop systems and future-proof builds. Fully compliant with ATX12V V3.1 and PCIe Gen 5.1 standards, it provides stable power delivery, supports large power excursions and rapid response to spikes, and includes a 20+4 pin ATX motherboard connector. Certified 80 PLUS Titanium and Cybenetics Titanium with Cybenetics Lambda A++ noise rating, the unit uses industrial-grade components such as Infineon CoolMOS and SiC SBD and comes in a compact black enclosure with a 135 mm axial FDB fan.

Advantages

The Taichi TC-1650T offers very high efficiency and low noise thanks to 80 PLUS Titanium and Cybenetics certifications, combined with premium components for long-term reliability. It supports ATX 3.1 and PCIe 5.1 for compatibility with current and next-generation hardware, provides a +5V BOOST voltage compensation switch to stabilise the 5V rail, and features iCOOL intelligent fan control to minimise noise at low to medium loads. The power supply also includes a full set of protections and an extensive 10-year warranty from ASRock.

Suitable for

• High-end gaming PCs and multi-GPU workstations

How to use

Install the Taichi TC-1650T into a compatible ATX case and connect the 20+4 pin ATX cable to the motherboard. Attach modular cables to the required rails for CPU, GPU and storage devices. Use the 5V BOOST switch to enable voltage compensation when stable +5V under load is required; otherwise leave it in default mode. Select iCOOL mode ON to keep the fan idle at low–medium loads or OFF for continuous fan operation when constant cooling is preferred. Ensure all connections are secure before powering up the system.

Recommendations

For optimal long-term performance, operate the unit in a well-ventilated case, keep dust away from the fan and vents, and use the iCOOL mode for quieter operation during typical desktop use. Verify cable routing to avoid obstructing airflow and consult the motherboard and GPU manuals for recommended power connector configurations.
