The 550 is the wattage, that is the number of watts it can supply, while 230 is the voltage. So yes, it is a 230 V power supply. There are no 550V power supplies. And you should try to get a better quality power supply because that unit is not good in terms of quality. What other options are available to you within your budget and available in your region?

This is slightly better quality for the same price: https://www.ple.com.au/Products/628632/Cooler-Master-MWE-450W-80PLUS-Bronze-Power-Supply

In that budget, definitely get this: https://www.ple.com.au/Products/628758/Corsair-CX550-550W-80PLUS-Bronze-Power-Supply

The EVGA 450 GD is also a good unit, can get that as well. 450 W is more than enough for a GTX 960, and you get gold rating instead of bronze on the above power supply, which means lower power consumption overall. It's up to you which to choose between these two.

Thanks for this information i will look at both of these psu’s these are good for a budget build, i will most likely get the gold rating
