Hi,
I am thinking of building a PC with the following components:
1. I5 4670K (150W)
2. ATI R9 270 or 270X (500W)
3. Gigabyte Motherboard (Approx 100W)
Plus a HDD 1tb and 2 4GB DDR3 RAMS( I dont know how much energy they would be consuming)
I need to know what should be the minimum PSU (in terms of Wattage) i should purchase for this system to function without any problems.
