Yes. Much better.
That 700W PSU has only 1 SATA power connector. Corsair 450W has 6 SATA power connectors.

Sansun Arctic Power PSUs are no longer listed on the Sansun website so you know they're older, discontinued models.

Or maybe they are Compucase/HEC Arctic Cooling PSUs? http://www.compucase-hec.co.uk/psu_arctic_power.htm

ebuyer.com listing details don't match the pictured item or the website tech specs
as in 2x 80mm fans, 1x SATA power connector, etc.

Not if your PC is only using 300 watts.

You also need to look at "usable" power. That means the 12 volt output. The 12 volt lines power the CPU and GPU. And anything over about 10 amps on the 5volt line and 10 amps on the 3.3 volt line is wasted capacity.
