I can help and tell me exactly where I choose, and distinction is the power supply which I find in the store.
Hrm, I'm not sure what you're saying there...What are the specs of the whole computer?
An estimate so far, but I would say atleast 1000w. For brands, I hands down recommend Corsair. Newegg is having a nice sale with rebates on them with free shipping. Hands down the best deal in town.
