I am the User to supply a Super Nintendo US. The console consumes 17W. Under these conditions the converter / transormateur makes no noise but tends to heat much during long gaming session. Surprising enough so that it is not even 50% of its maximum load (45W).
So, it is better not ask him too. If the load you had to feed is around 35-40W, take a superior range of the transformer.
Apart from that, it's a good product. The price / quality ratio is excellent.
