I'm looking to build a AMD APU rig using the following parts and would like to know what would be the smallest wattage PSU I could use?

APU can be set to 45w or 65w.

2 sticks of Samsung wonder ram

no optical drive, will use a USB drive when needed.

this case comes with a 250w PSU. Think that would be enough?

thanks for your time

Radeon 250 67 watts TDP....
APU you mentioned...65 watt
SSD 5 watts

roughly 137 watts... a 250 would probably be fine.

and the case is even cheaper on Amazon with prime shipping: http://www.amazon.com/Rosewill-250-Watts-Connector-RS-MI-01-BK/dp/B004Q7J1S0/ref=sr_1_9?ie=UTF8&qid=1395175005&sr=8-9&keywords=AL8250SFX

To op,

Hmmm....a 250w (quality) unit would certainly be more than enough for your setup, but from the images in the link the PSU seems to have no APFC (the red switch for 120/240V) which is kind of discerning in this day and age.

EDIT: This is the PSU that comes with the Rosewill case which is a Max-Power-rated unit (not a good sign) :

Although your consumed wattage would be relatively small, I would advise if you shop around some more.

Or get the cheapest one (price wise) you can find from this list:

Have to agree with eXXon... that is a majorly budget PSU! You would be better off with a better PSU... good power is a necessity!

Trouble is that everything on the 250watt / 350watt list add $35 -$50 to the price... and this looks like budgeted build.

I do have a 700w Bronze PSU sitting on a shelf, but feel that's huge overkill and wanted something smaller to fit the build better. The build is not set in stone as a budget build so a little more for a better PSU wouldn't kill me.

Thanks

How abut this Seasonic SS350 for 39$?

But I would recommend you get a PSU with at least one PCI-E 6/8-Pin power connector, in case you upgrade the GPU to a mid-range one in the future.
