small mixer or mic pre
most mic pre's and mixers have phantom power in them. If you're just going to record one mic at a time, I would look into a mic pre - otherwise, since you were talking about a Triton, you might want to get a mic pre and a mixer - a mic pre because you'll need one anyways, and a mixer to plug other stuff into (like keys, drum modules, etc.) and then into your soundcard.
Depending on the sound card you get, you could hook up your mixer/ mic pre to the sound card either through an XLR cable (the one with 3 pins) a 1/4" cable, or an 1/8" cable (the small headphone size connectors) - with most sound blasters its the 1/8" (maybe called 3mm sometimes) cable you use, and don't plug it into the Mic In, plug it into the Line In -
Do a little research on how to hook stuff up, especially different types of cabling - what balanced and unbalanced means, line-level vs. mic-level inputs, low impedance vs. hi impedance, grounding, shielding, electrical hum, etc. - and you'll figure how to plug it in, and you'll avoid the headaches that I currently have
This is important because even if you know how to plug stuff into a mixer and your soundcard, you're still probably going to have buzzing caused from electrical circuits - it's unavoidable with a computer. Also, on certain occasions plugging stuff in wrong can destroy your equipment - I learned that last week.
