I am planning to get myself a new pc this month. This will be my second one (my old pc was a useless Pentium III that is >14 years old). I will be using the new one mostly for 3D animation and graphics, video editing, gaming and movies. Please suggest a good psu for these specs:
Intel Core i5 4670
Asus Z87-A motherboard
Corsair 4GB 1600 Mhz DDR3 RAM
Asus AMD R9 270X 2GB GDDR5 graphics card
Seagate 1TB 7200rpm HDD
LG DVD writer
Cooler Master Elite 431 plus pc case
Is the Corsair CS550M good enough for this config? Or should I go for a 600W psu?
Also, in the near future, I plan to add an extra stick of RAM, another fan in the cabinet for better cooling and a decent sound card. Will the above PSU be able to handle this extra load as well?
Thanks in advance.
