Since when do computers start needing this ATX12V connector for things to work correctly? I’ve been having issues with my motherboard recently dying a slow death. So I stopped at the computer store yesterday and picked up a replacement. I get home, plug everything in, and get no video. I figured I had something loose or connected wrong, so I start unplugging various things to see if that’s causing the problem. About an hour later, I’m down to just the power supply, video card, and RAM and it still won’t boot. So I haul my butt back to the computer store and explain, using my vast computer knowledge, why I believe they gave me a faulty motherboard. Pretty much the first thing the guy says to me is “You did use this plug, yes?” pointing to the plug above. “Ummm, no.” Both of the guys behind the counter give me a look as if to say are you sure you’ve done this before/are you on drugs? I had never seen that plug on any of my other boards before. Maybe it’s not “new” but I haven’t built a computer from scratch in years, so it’s new to me. I asked him to hook it up to their test system there to make sure that the board isn’t faulty and sure enough it works. I drive home feeling like an idiot.
