Default Computer Power Supply?

I've done a search on this already, and it has been discussed in somewhat of a manner. Many people pointed out that the switching frequencies of these power supplies are bad for amplifiers, however with most T-amps using a laptop-style power brick, aren't those also using switching supplies? Since my computer is my only source, I was considering using a 12V molex connector from my computer psu to power the amp. Would sharing the common ground between my source (sound card) and amp be a problem?
