## Long description

BitsPower CR803 is an acrylic reservoir and pump combo designed for custom liquid cooling loops in desktop PCs. The unit integrates a transparent acrylic reservoir with a compact pump assembly to circulate coolant, providing a combined solution for coolant storage and flow management in a single component. Its clear acrylic body allows visual monitoring of coolant level and condition, while the integrated pump reduces the need for separate mounting points and simplifies tubing routing in compatible cases and mounting locations.
Advantages
The combined reservoir and pump design saves space and simplifies installation compared with separate components by consolidating coolant storage and circulation. The transparent acrylic construction enables easy visual inspection of coolant level and color, improving routine maintenance and leak checks. Integration of pump and reservoir into a single housing reduces the number of fittings and potential leak points while providing a stable mount for the pump assembly. The form factor is suitable for many desktop cases and mounting brackets made for combo units.
Suitable for
 Custom PC water-cooling loops requiring a compact reservoir and pump solution
 Systems where visual monitoring of coolant is desired
 Builds with limited space for separate pump and reservoir mounting
 Upgrading or replacing existing combo-style cooling components
Key specifications
 Material: clear acrylic reservoir body
 Integrated pump assembly: single-unit pump combined with reservoir
 Designed for use with typical PC liquid cooling coolant fluids
 Form factor: combo reservoir-plus-pump suitable for desktop case mounting
 Fluid inlet/outlet ports compatible with standard water-cooling fittings
How to use
Install the BitsPower CR803 into a compatible mounting location in the desktop case or on a bracket designed for combo reservoir-pump units. Secure the unit according to the case or bracket manufacturer instructions, connect inlet and outlet tubing with appropriate water-cooling fittings, and ensure all connections are tightened. Fill the reservoir with suitable coolant recommended for PC liquid cooling, then perform a leak test by powering the pump using an external power source or the system power header while keeping the rest of the system powered off. Monitor coolant level and flow until air is purged from the loop, and top up the reservoir as needed before normal operation.
Usage recommendations
Use coolant types and additives that are compatible with acrylic to avoid clouding or degradation. Ensure all fittings are correctly sized and tightened, and follow standard leak-testing procedures before powering other components. Perform periodic inspections of the acrylic reservoir for scratches, cracks, or clouding and replace the coolant according to manufacturer guidance or observed contamination.
