Yes, BUT...when I see "480 watt" the only units that come to mind are PSU-shaped objects like Logisys, HEC, and similar ..."devices." Those are best described as firecrackers with uncertain fuses, possibly dying for no apparent reason (e.g. someone turned on the garbage disposal, or a hairdryer, or your A/C cycled), and possibly killing attached parts.
Not much information was given. It really doesn't say why they are asking this question. Many different things can be at play. I agree with you though it needs to be at least 80 plus bronze and a reputable brand unless the cpu and psu are stock on a manufactured pc and they are just upgrading the gpu.
