Is my PSU enough?


I am planning to buy a new PC this year.

I want to ask if my NZXT Hale82 v2 550w will be enough.:


CPU:Intel core i7 4770k
MOBO:MSI z87 Mpower MAX
RAM: Corsair Vengeance 8GB 1600mhz CL9
SSD: OCZ Vertex 120GB
HDD: Western Digital 500GB

I'm going to Overclock the CPU to around 4.5GHZ.

  1. I think so.
    Even stressed to the top with furmark a Intel Core i7-3960X @ 4.3GHz + GTX 780 system barely broke the 400W global power consumption barrier on some test that I've read.
  2. it will suffice but better go with a 650w one. it will leave you more room for overclocking and it will run cooler and quieter than the 550w .psu are more efficient on 50% load

    GeForce GTX 780 - 42A and a 600W PSU minimum recomendation so with 41.25A the nzxt on the 12v rail is on the edge. this is realy an great offer being at the same price as the nzxt
