Have you ever wondered about the claims companies put on the side of their PSUs? I mean you see all kinds of numbers and there are many different rating systems for PSU power.
Well it seems that Cooler Master wants to show you exactly how much juice their new Silent ProM 500 Watt PSUs really have. To do this they actually hooked one up to a car and using nothing but the 500 Watt PSU were able to turn the engine over and get it running.

After detaching the car's own battery, the Cooler Master team attach their power supply instead. Jump-starting the car requires 29 Amperes, which the 500W Cooler Master Silent Pro PSU seems to have no trouble delivering. Not only that, but there's some spare juice left over to sound the horn, too.
I don't think they're suggesting that you should carry a 500W computer PSU in your glovebox "just in case"; after all, you'd need a long AC extension lead.
