Delinx 36W 12V PC Fan Power Supply
Delinx offers a versatile AC-to-DC power supply designed for PC fans and other cooling devices. It accepts 100-240V AC input and provides a 3-12V DC adjustable output up to 36W. The unit supports standard 3-pin and 4-pin PWM fans and includes a multi-speed controller to balance noise and airflow. This makes it suitable for PC, laptop, receiver, Xbox DVR, and console cooling needs, particularly where multiple fans require synchronized speed control.
12V PC Fan Speed Controller (Tokatuker)
Tokatuker’s 12V fan speed controller converts 100-240V AC input to a stable 3-12V DC output, delivering up to 36W. It supports both 4-pin and 3-pin fans and includes a 4-way splitter cable to manage multiple fans simultaneously. The wide input range makes it compatible with global voltages, ideal for multi-fan PC cooling and external electronics projects requiring coordinated fan speeds and reduced noise.
Coolerguys Fan Power Supply
Coolerguys provides a straightforward 12V DC power supply with up to 1A capability, designed for reliability and compatibility with 3-pin and 4-pin PWM fans. It features a flexible 5-foot cable and supports standard extensions and splitters. This option is well-suited for compact cooling setups, LED PC components, and devices requiring stable, low-noise fan operation with minimal wiring complexity.
Delinx 12V Power Supply (24W) With Splitter
Delinx’s 24W adjustable power supply accepts 100-240V AC input and outputs 3-12V DC, with a maximum of 24W. It’s compatible with standard 3-pin and 4-pin PWM fans and ships with a splitter cable. The built-in multi-speed controller enables precise tuning of noise and airflow, making it suitable for gaming consoles, DVRs, and dedicated cooling fans in compact builds where space is at a premium.
LitStar 12V 2A Power Supply
LitStar’s 12V 2A power supply is a flexible option for LED strips, CCTV cameras, routers, and other 12V devices. It features 100-240V input with automatic identification of the required current, a 5.5×2.1mm barrel connector, and 8 interchangeable tip options. While primarily designed for modular use, it can power small PC fans and related peripherals when paired with appropriate connectors and splitters.
SHNITPWR 12V Fan Power Supply
SHNITPWR’s model delivers 3-12V DC output up to 2A with 110V-240V AC input, featuring a 2A maximum current and a fan splitter cable that allows two fans to run in parallel.

Buying Guide: Key Purchase Considerations
When selecting a 12V fan power supply, consider output range, maximum current, and compatibility with 3-pin and 4-pin PC fans. If multiple fans must run in parallel, ensure a splitter cable is included or readily available. Noise level, efficiency, and heat dissipation matter in compact or enclosed spaces, so choose units with good thermal design and stable regulation across the input voltage range. The presence of a speed controller helps tailor airflow to your cooling needs without excessive RPM spikes. For global setups, prefer models with 100-240V input and clear labeling for safe operation.
Compare products by these dimensions:
– Output voltage range and current rating: 3-12V, 1–3A (or higher for larger builds)
– Fan compatibility: 3-pin, 4-pin PWM, or both
– Availability of splitter cables for multi-fan setups
– Input voltage tolerance: 100-240V AC
– Built-in speed control: direct knob or external control
From compact gaming rigs to media centers and CCTV installations, these options offer varied wattage, connector types, and control features. Evaluate your chassis space, the number of fans, and the desired level of noise to identify the best match for your cooling strategy. Always verify connector compatibility with your specific fans and devices before purchase.
