Compact black cylindrical water-cooling pump with PWM connector, 62 by 62 by 37 mm

Bitspower

Bitspower S1 Pump PWM 960L/h 12V 17W

SKU CH-54CN-2TAEK

PWM-controlled D5-style pump delivers up to 960 L/h at 12 V and 17 W, with a 50 000-hour MTBF and 60 °C max fluid temperature

  • Product typePump
  • PWM control enables precise speed regulation
  • 960 L/h maximum flow delivers strong coolant circulation
  • 17 W power draw keeps energy use low
  • 50 000 hour MTBF indicates long operational life
  • Compact 62 x 62 x 37 mm size fits tight loops

Bitspower S1 Pump PWM

The Bitspower S1 Pump PWM is a 12 V DC liquid-cooling pump rated for 17 W power draw. It delivers a maximum flow of 960 L/h and supports PWM speed control. The unit measures 62x62x37 mm and carries a 50 000-hour MTBF rating.

Suits custom-loop builders needing PWM control

This pump suits builders assembling custom water-cooling loops who want PWM-regulated flow. It is not for users requiring flow beyond 960 L/h or system temperatures above 60 °C. Buyers needing a different form factor or voltage should look elsewhere.

960 L/h flow headroom

At 960 L/h the pump comfortably circulates coolant through typical CPU and GPU blocks with standard tubing runs. Headroom diminishes when multiple restrictive blocks, long tubing lengths or high-resistance radiators are added. The 60 °C fluid-temperature limit also caps use in extreme heat-load scenarios.

Questions about this item

What power connector and voltage does the pump need from my PSU?

The pump runs on 12V DC and draws 17W, so a standard 12V rail or PWM header on the motherboard can supply it.

Will this pump fit inside the Bitspower reservoirs listed as compatible such as the BPTA-WDP700M-R-PWM?

Yes, the 62x62x37mm dimensions match the mounting pattern of all compatible reservoirs in the list.

How can I confirm the pump is running at full speed after installation?

Check the PWM signal in BIOS or monitoring software to ensure it reaches maximum duty cycle and listen for steady operation up to the 960L/h flow rating.
