430 or 500w psu for this build?

Hello, I have recently built a new pc mainly for work but occasional gaming. I am wondering whether to get a 430 or 500w power supply to go with it.
My spec at the moment is:
AMD FX 4100 (no OC)
4gb ram
Radeon 6770 (I will later upgrade to either a 6850 or 7770)

Thanks in advance :)

More about 500w build
  1. 430 is just fine even with an overclock. If its the corsair then that unit is solid. If you want more overhead for future upgrades then go with a 500w as long as its reputable
  2. I'd get a 500W, just in case.

    The FX-4100 will be the main power hog within the system, the extra 70W would be be safe.
  3. The 5770 is just the same as the 6770 at 80-90w of consumption. I highly doubt the 4100 would use 340 Watts with the rest of the system. 430 is safe if its the corsair unit along with overclocking. I still agree with muffin on the 500w as long as its a good brand for more overhead and future upgrades
  4. I think it depends really. You could get a cheap 'SHAW' Viper-860 800w for $25 (AUD) but it would probably either fail, kill your components via voltage spikes, over voltage, blow up - something of that sort anyway where as a Corsair 500CX 500w for $69 would be much more reliable at a slightly higher cost for less 'w'.

    In a nutshell, you shouldn't buy products based on their 'w' rating.

    What 430/500w PSUs did you have in mind?
  5. Exactly my point in saying " reputable brand"

  7. That psu should work just fine for what you want
