pasabot ani, ayaw ug settle anang mga generic (like dala sa chassis inig palit) kay they are not true-rated units... basin gamay ra kaayo ang wattage ana nya in actual. mabitin ang GPU nimo labi na imohang i-OC. maguba lang unya sya later on or, dili maayo ang performance nya kay need sya ug more power input (other than the 75W max that the PCIe slot can give) but your PSU can not provide. you can check Antec, Corsair, Cooler Master (just to name a few)... ug uban pa... ubay2x man available na brands pud dha sa atoa na mga true rated PSUs... daghan maka recommend nimo ani dri... ako, dili man ko choosy ani PSU ug brand... hehehe... I even used 2 Chinese branded PSUs here... SAMA ang brand... so far, so good... one unit is 4+ yrs while the other one is 3+ yrs old... both are still providing ample juices to the rig that they are powering...
