My brother, who is 8 years old and knows nothing about computers other than what I've taught him, his power supply in his dell is dead. I used a PSU tester and one of the lights that should have been lighting up wasn't. The problem is that because Dell is so stubborn, I can't find a psu to match up with his case. The, for lack of a better word, plug has to be on the upper-left side and there can be no on/off switch. If I could have help locating such a psu I'd be grateful. God I hate talking all formal like this.I know it's not required, but it's a habit.
