Dear colleagues of I repair, I need to know with which TVR I can replace the TVR 07271 I burn and I do not get an equal one, it is from a 500 W. power source of a pc.

It's a matter of knowing the tension that drives where it burned. Being for example 220V, you buy one of 250V of the same size. And if it was 110V, you put one of 130V also the same size. The size is for the power that can dissipate.
