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 :)

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

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.

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

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?

Exactly my point in saying " reputable brand"
