Hello
I got a 480W PSU but doesn't seem like a good brand

imo u should try always to use a decent PSU, such as TAGAN/Enermax

its well worth it !!!

wattage isnt the be-all and end all of psu's, rails are just as important, different psu co's measure wattage differently, most are "PEAK" wattage, NB. NOT able to keep sustained
