You can use it with your DAW if you have a MIDI interface (you probably have MIDI ports in the interface you're using with your DAW now).
MIDI doesn't have anything to do with sound whatsoever though so you should also grab a couple 1/4"-14" cables ("guitar cords") to run audio out of the MPC into your DAW interface. When it comes to audio the "you get what you pay for" saying is incredibly important (unless you find a lucky deal on used gear) so how much you spend on the cords will make a big difference. Whether your ear is sensitive enough yet to hear the difference or not, it matters A LOT. I use only Mogami gold cables but I have a fairly big annual budget because this is my job (I'm an audio-engineer) so if you don't want to spend more on cords than you spent on your MPC then Monster will do. Just get the best ones you can afford (preferably gold-plated).
I just grabbed an MPC500 at a pawn shop for $70 earlier today. No AC or CF either but I'm sure one of these adapters I have in the studio will work, I'm gonna need a ton of CF cards to transfer all my ASR's Zip-Disk of sounds to CF anyway, and I had him throw in some new batteries in the meanwhile (still gotta get the RAM expansion though, none of mine fit).
I went in there to buy another pre-amp and saw it sitting there. He clearly didn't know much about it when he told me "$150" so I was like "I don't know. Samplers are so old school. I might be able to use it as a MIDI controller for the drum pads, I guess, maybe if it was cheaper." and he was like "$80" so I told him "$75" and he started acting like he couldn't budge. I left the shop. Came back an hour later and pulled out $70 and walked out with it

I'm getting damn good at this pawn shop thing. I would've paid $300 or more no problem so it made my day lol.
