Can a 220W PSU power a graphics card?

[dutch777]

I have a compact desktop whose PSU is rated at 220W. It is equipped with Intel G2020 (55W) and a standard HDD, DVD RW, etc.

So can I add a graphics card such as Radeon R7 250 or GeForce GT 640 (both rated at 65W) and not worry about PSU failure?

That's cutting it real close, possibly will run into issues. Can you upgrade the psu at all? at least a 300/350w?

Edit:
Is the psu a external brick?

A good ATX 2.3 spec PSU should be able to handle that fine. A not-so-good ATX 2.1 or earlier spec PSU, probably not as much.

You could also consider a 750Ti - currently the best GPU under 75W.

It's a low profile card so my options are limited.

The PSU is manufacturer by Acer and is featured in their Veriton compact series from last year.
