The HD5450 is the same as an HD6450 (I have that one) and
it is a 13 watt maximum card. You will nave no trouble
driving that, as that's a low power card suited to media center
applications. I have that card in my Dell Optiplex, as the card
has no power connector and runs off slot power.

The CPU is 10A on a 13A output, which is fine. Because
you haven't used up all your Peripheral power, there will be
sufficient shared amperes, to not be a problem.

The HD5450 is anywhere between 3 watts (idle) and 13 watts.
You can't do much better than that, on a discrete card.
And that card of mine, works in Win10 22H2. The WDM driver
for it, is "good enough" for the job.

Now, let's check my memory.

Listed as 19 watts.

Mine is 18 watts.

I don't know if Furmark will run on that, for test.

It's not a closed loop card, so if you can find a program
to drive is hard enough, it might draw 20 watts :-)
