AMD HD 7450,
2*8GB Ram DDR3,

Look for something like a Corsair 650W or equivalent for that build.

If you want to upgrade to more power hungry equipment a good brand name 850W. That is overkill for your described build though.

Don’t cheap out on the PSU, a bad one failing can destroy the rest of your hardware and data.

550w psu will be best for you

I bought a Corsair CX550 recently as a replacement for an old rig, knowing the PSU has only 3 SATA power connectors.

The MSI MAG is more generous with 5 SATA power.

The CX550 is as light as a feather and cheaply constructed. I prefer the heavier RM650/750/850 for more important builds.

Even 300w is plenty. What's you country/webshop for purchase a PSU?

The only problems with 300W are finding a name brand manufacturer who supplies the 300W psus and finding parts. I found one made by Be quiet and it isn’t ATX. Price wise there is £30 difference.

For an extra £30 a more powerful gpu than the 1050 can be accommodated with confidence.

650W supplied my 2700x and a R9 390 with ease for a number of years.
