Please advice if VX450 will be compatible with this computer specification.

Yes that PSU will work fine for your PC.

If you have a couple Molex to Sata power adapters you could spend a little less and get this Seasonic

Yep, as Eric said, it will work fine. The seasonic he suggested would also be great. If you really want a Corsair, you can get the 400W version and save a few bucks:

…or spend a bit more so you actually can use your PSU if you change hardware…

I wasn’t sure how many sata connectors the 400W corsair has, just found it does indeed have 6 total sata connectors according to a newegg reviewer. So it would be a great choice.

The Corsairs and Seasonic mentioned are all good selections and will be ample for the computer as specified, all appear to have a 5 year warranty.

The CX400 is good, but the components used are a slight drop in specs from the VX450. (Still a good PSU though.)

If you lean to the VX450, you might also consider the HX450.
The internals look like a clone of the VX450, but it is modular and has a 7-year warranty. Downside, it is also a bit more expensive.

The 450HX is brand new and there seems to be no availablility in the states right now.
