Answer 1

You do not 'need' a 3 pin plug ... that third 'pin' is just to 'ground' the plug to prevent 'shocks' from happening. Just put the 'two pins' in where they belong, and use a 'surge protector' with a 3 pin plug into the wall and you'll be 'safe from shocks' as well as 'power surges' and power outages hurting your computer.

Answer 2

How did you pick the power supply? In general, buy a supply that matches or exceeds the Amps of the old one in every voltage, and that has the connectors you need.

That said, there are some older boards with supplemental 3 pin connectors on them that are just unnecessary. The PC works fine without it. I cannot be sure if your PC is one of those or not. Usually replacement power supplies for these have a note in the installation instructions that the connector is unnecessary.

Answer 3

if you are talking about the 110 volt (two blades and a ground pin) you can go to wal-mart or anyhardware store and get an adapter for under a buck, you plug a three prong into it and it just gas the two blades comming out, it's about an inch long and usually gray

Answer 4

Some have it to have temperature control on the fan of the power supply. It really isn't common.

Answer 5

Yes
