Is 430 watts from a Corsair CX430 enough to power this build?

AMD A4-3400 Llano 2.7GHz
SAPPHIRE Radeon HD 5450 1GB
SONY Black 18X DVD-ROM 48X CD-ROM SATA DVD-ROM Drive Model DDU1681S-0B

Later I will upgrade my graphics card to a Radeon HD 7770, would it be sufficient then?

Should be fine. for the 5450. Youll need the cx500 for the 7770 upgrade though!

more than enough, if its possible to run an i5 and a 6870 on a decent 430w psu, then a low powered HD x450 and an apu should not be costly on the psu.

Yes cx430 is plenty for a gt430. Definitely consider the cx500 if you are planning future upgrades.

I dont know very much about hybrid crossfire but amd GPU's should work better with your APU.

Best solution

The 7770 only uses 80 watts at max, youve got more than enough psu for it. and it was a pleasure

It probably will work. although Amd recommends 500w supply, better to stay within the guidelines. [...] 770.aspx#3


Do you know that they recommend 500 watts or greater for the 7970 as well ?

Do you know that the 7970 can draw 3x as much power under Furmark load ?

How about the apu? It's a pretty low power item

Hmm, 100 watts for the 7770 running Furmark + 70 watts for the basic system running LinX
170 watts

With the specs he gave us, there's not much chance of the OP ever putting a 50% load on a CX430, it's more than enough
