Frequently Asked Questions
What is the Cooler Master GPU Shield Adapter?
It's an inline adapter cable that sits between a graphics card and power supply, monitoring current across individual pins on the 12V-2x6/12+4-pin connector and providing LED and audible alerts if an anomaly is detected, according to TechPowerUp and KitGuru.
How much does the GPU Shield Adapter cost?
TechPowerUp reports it's available on Cooler Master's US online store for $49.99, while KitGuru reports a European price of around €29.99.
What happens if the GPU Shield Adapter detects a fault?
Per TechPowerUp and KitGuru, the adapter can actively reduce current or system power draw when higher-than-normal current is detected, in addition to triggering visual and audible alerts.
How is this different from Cooler Master's existing GPU Shield tech?
TechPowerUp notes this adapter improves on Cooler Master's GPU Shield feature already built into some of its power supplies, since that built-in monitoring isn't visible in many modern PC cases, whereas the adapter's LED ring can be positioned to be seen.
