Whether you think of choosing corsair SMPS 550w or anything else; it has to be as per the requirement of your computer. Remember that the SMPS or PSU are available in diverse wattage (W) and with the diverse sum of currently listed on 12V Rail. The sum of current on 12V Rail is somewhat the most important and going to be deciding factor when selecting an SMPS. The reason for this is because all the prime components such as CPU, Hard Disk, Graphics Card, Fans etc. Draw their power from that of 12V Rail. Every single SMPS has a different amount current listed on that of 12V rail but you must definitely note that this current should definitely be sufficient enough for an SMPS or that of PSU of certain Wattage.
This simply means that a 400W SMPS must have at least 30A listed on its that of 12V rail, a 500W must surely have 40A or more and that of so on. Also, keep in mind that the 12V Rail in a single SMPS might or might not be forked into smaller units and in case it is divided then these kinds of psus are called multiple 12 rail power supplies.

You should know that every single PC has its own power needs and for that power supplies of diverse capacities are available in the market. So, for diverse PC configurations, a power supply with a specific capacity is mostly used.

So, it is wiser and safer to use the higher volume PSU rather than that of making use of the lower capacity one for the given power needs of your PC.
