Hi guys,

I'm looking to redo my system as my CPU/MOBO/RAM is pretty out dated.

recently my old PSU died so i got a new one (XFX Pro 550w)

This will be my system when done

i5 2500k with a 4.5ghz OC
Gigabyte Z68XP-UD3
Corsair Vengeance 1866mhz (8gig)
MSI HD6870 H.A.W.K Twin Frozr III
Corsair Hydro H80 CPU cooler
Coolermaster HAF with all the fans included.
XFX Pro 550w

Now my question is, Will my current PSU do the job? i know it is a good quality one dedicated 12v rail but im not sure if its gonna be enough wattage to do the job ?

Any help much appreciated.
