Inter-Tech MINI-ITX PSU 120W REV. 2
Inter-Tech MINI-ITX PSU 120W REV. 2
The Inter-Tech MINI-ITX PSU 120W REV. 2 is a specialised DC/DC power supply board designed for compact computer builds. Its main function is to convert an external 12V DC voltage into all the necessary voltage rails for the motherboard and components. This approach effectively solves the problem of limited space in small Mini-ITX cases where standard ATX power supplies will not fit. It requires connection to an external 12V power adapter with a corresponding wattage, which is not included.

Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the form factor is its wattage. This indicates the maximum number of watts the power supply can continuously provide to the computer's components. It is a good idea to use a web calculator to determine the optimal wattage based on your chosen components.
Design
This power supply for Mini-ITX takes the form of a compact printed circuit board, which reduces space requirements. Connection to an external 12V adapter is handled by the included cable with a socket, which mounts directly into the case wall. A nut is supplied for secure fastening, creating a stable and safe power point for the entire system's external power.
Power and connectors
The total power output of 120W is designed for low-power builds, typically office or multimedia computers on the Mini-ITX platform. The cabling is fixed to the board and includes the basic set needed to get the system up and running. It includes a 20-pin ATX connector for the motherboard, a 4+4-pin connector for the CPU, and one Molex and one SATA connector for connecting hard drives or other peripherals.
Protective features
For safe operation and to protect the connected components, this power supply board includes a set of key protection circuits. These mechanisms actively monitor the electrical parameters and immediately disconnect the power if an anomaly is detected. Overvoltage protection prevents damage from high input voltage, undervoltage protection addresses the opposite problem, and overload protection prevents the total power from exceeding 120W.

80 Plus certification in the European market
The 80 Plus certification was created to objectively evaluate the efficiency of computer power supplies. This gives users a simple and clear way to compare different models. On the European market (where 230V is used), there are six levels of 80 Plus certification with set requirements for computer power supplies. Higher energy efficiency primarily means lower energy consumption.
| PC PSU load | Efficiency at 20% load | Efficiency at 50% load | Efficiency at 100% load |
|---|---|---|---|
| 80 PLUS | 82% | 85% | 82% |
| 80 PLUS Bronze | 85% | 88% | 85% |
| 80 PLUS Silver | 87% | 90% | 87% |
| 80 PLUS Gold | 90% | 92% | 89% |
| 80 PLUS Platinum | 92% | 94% | 90% |
