Specification
AC Input
Auto range 115 -230V. Suitable worldwide. The suitable voltage is automatically selected. No setting is required.
Power Output
270Watt. A PSU more powerful than your original PSU, will not harm your PC. The PC only draws the power it needs. More power will allow future upgrades and guarantee a more stable system. The higher the power output, the better.
Colour
Grey
Ventilation
1x 40mm fan at rear (near cable exit). Some similar PSUs come with the fan at the front (near the power socket). The airflow in both types of PSUs is exactly the same: the hot air from the PC and the PSU is expelled efficiently via the vent holes.
