Its risky buying power cords without trying them first. Why not use Cable Company? They'll send you a box full of PC's to demo. Not only that, they're the best resource for info. If you tell them what component the PC is for, they have a database that can show you every power cord they ever lent out to customers with the same component. Also, they keep track customers comments for every cable they lend out, and what cable the customer actually purchased.
