The 450W is the bare minimum it'll need. That also means it'll be running close to full capacity it's whole life which will be bad for the system and shorten it's life. If your PSU dies there's a risk the rest of your PC will go with it. Where as if you go with a high wattage high quality unit, it'll be a lot more comfortable as it'll be operating at a lower percentage and therefore last longer! It's very likely that the RMx system in the spec will outlast the rest of the PC.it suggests at the check out that change to a 450w power ? whats the plan for this the power
An analogy I like to think of is that it's similar to a car engine, with the revs being the wattage used and the redline being the maximum wattage. If your revs are always close to the redline, it's bad for the engine, where as if revs are low and redline is high then it's much happier. It's the same with the wattage of PSU's really
