you are assuming your power supply is of good quality, and that you can nearly max it out without it blowing
really should not load psu's beyond 80%, that is assuming they can actually deliver the wattage they claim
especially if they are crap quality, because cheap makers often straight up lie about this and exaggerate the wattage
