The 80 PLUS rating
- 80+ Bronze — the sensible minimum, about 85% efficiency;
- 80+ Gold — 90% efficiency, less heat and noise, longer warranty;
- Modular cables — fewer cables in the case and better airflow.
12V units for security systems
Cameras, intercoms and access control run on 12V. Four HD cameras need a 12V/3A unit and eight cameras 12V/5A. Add headroom and allow for losses over long cable runs.

Frequently Asked Questions
How much does a power supply cost?
At ITGS power supplies cost between 21₾ and 450₾. 12V units for security systems are 21₾–90₾, and ATX PC units 170₾–450₾.
How many watts do I need?
Add up the draw of your components and add 20–30% headroom. An office PC needs 400–450W, a gaming build with an RTX 4060 550–650W, and an RTX 4080 850W.
80+ Bronze or Gold?
Bronze is the sensible minimum (about 85% efficiency). Gold reaches 90%, with lower running costs and less noise. For a machine running around the clock, Gold pays for itself.
What is a modular PSU?
In a modular unit the cables detach, so you connect only what you need. That improves airflow and tidies up the case.
