It is important to maintain a stable power outage to your graphic cards, and unfortunately, not all power supply units have the built-in power surge protection, which leaves your graphic cards vulnerable to damage. The PS-200, however, can remedy and prevent those situations. It is a new unit developed by CoolMax that absorbs and safeguards your graphic cards up to a +12V electrical power surge with a REMI cord that can reduce electronic ripple and noise to stabilize the EMI interference. The PS-200 is the ideal tool to help you safeguard your graphic cards.
