I am getting a 450 watt PSU, I did a power test on cooler master power supply calculator and it said I need 460 Watts. Will this be a problem.
Thanks in advance

It's not entirely accurate but has a basic baseline all of then give a overkill estimate that I have seen.. if it recommends 460 watts then I would not consider recommending a 450 watt and who knows if the 450 watt can even come close to putting that much out.
It is much better to add up the TDP of the PC then allow for overclocking and such then get a PSU that can run that PC under a full system stress test and use in the 75/80% area of the PSU since that will not be a realistic power draw under most peoples normal use like gaming.
He also never said if the 460 number was the recommended wattage or what the system would pull (never even been to that site so not a clue what it tells you)
Their also people here that will tell you that a card needs much more power than it will just because it will draw that much running some benchmark test that your average user will never do and is in no way what the card will use under normal use.
