⚙️ Fit Notes
- Match your original power supply part number whenever possible
- Confirm your original PSU is a 290W unit with the same connector layout
- Confirm your system uses an 8-pin P1 main power connector and 4-pin P2 12V CPU connector
- This PSU is intended for compatible MT / mini tower systems
- This is not intended for small form factor, ultra-small form factor, micro, all-in-one, or slim chassis systems
- This is not a standard 24-pin ATX desktop power supply
- Compare the physical dimensions, rear AC plug location, fan orientation, mounting screw points, and cable routing before ordering
- Some later tower systems use different 300W, 365W, 460W, 6-pin, 10-pin, or different proprietary PSU families and are not interchangeable unless the original part number matches
- This power supply requires a standard C13 AC power cable, sold separately
- This unit does not include an AC power cord unless shown
- Always disconnect the AC power cable and allow the system to fully discharge before replacing a power supply
- Do not install in systems requiring higher wattage, a different chassis-specific PSU, different mounting points, or a different power connector layout
