Power supply unit MSI ADP180TBHN 180W - ATX internal PSU for small form factor systems

MSI ADP180TBHN is a 180W internal power supply unit designed for small form factor and compact ATX-compatible desktop systems. It supplies a fixed 180-watt output intended to power the motherboard, storage devices, cooling fans and low-power add-in components. The PSU is suitable for OEM replacements and system builders who need a compact internal power source for basic computing tasks, office work and HTPC (home theatre PC) setups.

Advantages

The compact design of this MSI 180W power supply enables installation in space-constrained chassis while maintaining standard ATX connector compatibility for motherboards and common internal devices. With a stable fixed output, the unit provides consistent power for low-to-moderate loads and reduces the need for external adapters. The internal layout and connectors are optimized for small form factor builds and OEM-style replacements, offering straightforward swap-in compatibility in compatible systems.

Suitable for

• Small form factor desktops and compact ATX-compatible cases
• Office workstations and business PCs with low power demands
• Home theatre PCs (HTPC) and media centers
• OEM replacement units and system repair/upgrade projects

Key specifications

• Output power: 180 watts total
• Form factor: internal ATX-compatible small form factor
• Designed for low-to-moderate system loads (motherboard, storage, fans, low-power cards)
• Cooling: internal fan (integrated) for thermal management
• Connectors: standard motherboard and common peripheral power connectors for compact systems

How to use

Turn off and unplug the system before replacing or installing the PSU. Open the case following the chassis manufacturer’s instructions, remove the existing unit if applicable, and position the MSI ADP180TBHN in the designated PSU bay. Secure the unit with the appropriate screws, connect the main motherboard power connector and any required peripheral power leads for storage or fans. Verify all connectors are seated properly, then close the case, reconnect power and perform a system power-on test to confirm stable operation.

Usage recommendations

Ensure the total system power consumption remains comfortably below 180W, accounting for peak loads. Use the PSU in well-ventilated enclosures and keep internal dust buildup minimal to maintain cooling performance. For systems with discrete graphics cards or high-power components, select a higher-capacity PSU instead of this 180W unit.
