Basically, a solid power supply (housing, cable and so). It is warmer than the original that because cable cut the plug was no longer usable. But ok, if the manufacturer has done his homework and the power supply does not break through the larger cache thermal load, it should be a bit warmer from me. No Matter. But what struck me recently. I have the replacement power supply already about 6 months in operation and it performs up to the following point his service. The problem is the DVB-T receiver with an ExpressCard. This reception is disturbed by the power supply in such a way that no more Emfang is possible. The whole thing in operation at a house in the attic with antenna preamplifier and household distribution, which goes smoothly on several other receivers in the house. So it is not an effect of a borderline bad signal. It's just that the receiver completely collapses as soon as one infects the power supply (via notebook battery the reception so is consequently still problems). The DVB-T reception had been with the original power supply is no problem. Bit annoying ...
