I think it's some kind of test for prolink's playtvs, but i'm not sure about this.
part of a graphic driver?

The powers.exe program is used to perform internal testing of ProLink video cards. If you have prolink graphic hardware and use the Prolink Test tool you should leave this process running. Otherwise, it can be terminated.

It is part of the Prolink driverset for their video capture/tuner cards. It showed up when I installed my CX881-P video capture card and driverset.

it comes from my PlayTV pro tv-card, and i have no problems at all.
It is commonly used by video capture cards. You don't have to format just uncheck it from the start-up window on msconfig

Best practices for resolving PowerS issues

A clean and tidy computer is the key requirement for avoiding problems with PowerS. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
