What amount of a power supply is enough for a normal PC
Depends on your definition of "normal PC". The average around these is 700W imo.
Thnx for explanation & am new to building PC, by normal PC I mean not the high-end gaming PC.
Am building this PC..plz suggest me the right PSU.
Asus P8H77 -M LE-
Core-i3 3220
Corsair Vengeance -4x2- 8 GB
HAF 912 Case
1 Tb 7200 RPM
In the future I will install a GPU like Geforce 650 or Radeon 7750.
