Is 550w enough???

I have this OCZ ZS Series 550W 80 Plus Bronze psu here:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817341047
and I've been running my computer since about February (somewhere around there) and it's been great :) , here are my specs:

-i5 2500k
-Asus Maximus IV Gene-Z/Gen3
-OCZ ZS Series 550W 80 Plus Bronze
-Double D[issipation] HD 6870 by XFX
-Hyper Plus 212
-8GB Kingston Blu RAM
-1 TB HD and 160GB HD
-HAF 922 as my case

Anyways, I decided I want to try oc'ing for the first/second time (I messed up my first time lol when I got my computer :( and want to try again with a better guide this time :) ;) )...
I want to know if 550 watts from an 80 Plus Bronze CPU will be enough...

Thanks guys ;) :) and please respond ASAP :D !

  1. Go ahead, the psu wattage is ok.
  2. yes, 550 watts will be enough, i have a 400W psu, the same gpu, and a CPU that uses the same ammount of power, and i haven't encountered any issues

    Okay cool :) ;) ..
    Even with overclocking it will be okay?

    A system with a single HD 6870 requires a 500W PSU with at least 32A on the 12V rails and two 75W 6-pin PCIe power cables. Your PSU has sufficient PCIe power connections and has 38A on the 12V rail. It's obviously sufficient for your stock system and has sufficient reserve power for mild-moderate OCs on the CPU and GPU.
  5. BTW your real-world power consumption at full load is under 300W: http://www.guru3d.com/article/radeon-hd-6850-6870-review/10/
    It was only 295W for a system with a highly OCd, power-hungry i7-965.
