My friend owns a CyberPower PC that he bought six months ago. He wanted to upgrade the video card and I offered to help him.
The old card did not have a power connector on it, but the new one does. Using the adapter provided by the manufacturer, I connected the new video card to the power supply.
The card worked for three weeks but today he reported that the computer turned off randomly while he was playing a game. Any attempts to turn the computer back on are unsuccessful.
Since CyberPower built the computer and knew what components were being installed, I'm assuming they used the minimum required power supply to get the job done.
Is it possible the new video card was drawing too much power and it fried some circuitry in the power supply?
If I replaced the power supply, can I expect everything else to work again? Or is it possible that additional components have been damaged?
Update
Replacing the power supply ended up working. The system is 100% functional again :)
