PSU
The component you never cheap out on.
The power supply feeds everything and protects everything. We check real capacity, efficiency class, protections and the headroom your GPU transients demand.
WHAT WE CHECK
- Real vs advertised wattage
- Efficiency rating (80+ tier)
- Protection circuits (OPP/OVP/SCP)
- Connector set for modern GPUs
- Headroom for upgrades
