I got a new Antec VP500 PSU...the problem is I got a power cord which is only 2 pin...no 3 pin...means that it isn't grounded...but the quality is really great... So i went to a local store and saw for a power cable...but they had Terabyte power cable( of lesser quality)....so I wanted to ask should I get a cord from local store which is of lesser quality? Or can I cut the power plug and attach a 16A pin myself( I m used to do some electronics)?
