Gigabyte describes its new PSU range as a 'Hardware Guardian', protecting your graphics card from melting and presumably fighting crime in its spare time

Not content to let MSI run away with the GPU-protecting power supply market, Gigabyte has announced its new Gaming Series of PSUs. The company says that these units are the ultimate "Hardware Guardian" for high-performance systems, thanks to their T-Guard active thermal monitoring technology.

Complete with a promotional image showing a superhero-like figure between two of the aforementioned models, no less. Similar to MSI's efforts, Gigabyte says these power supplies have built-in sensors to monitor 12V-2x6 connector temperatures in real-time, and can reduce power to the GPU if they detect any abnormalities.

Which should help allay concerns about another meltgate, for anyone still worried. There's also a dual-colour cable design to help prevent any connector insertion mishaps, and the PSUs have been awarded the Cybernetics ETA Platinum certification and maintain 80 Plus Gold status, so they should be pretty efficient, too.

The range supports ATX 3.1 and PCIe 5.1 standards, and comes in 750 W, 850 W, and 1000 W capacities, with a total of six models to choose from—including some white and silver "Ice" models that look rather sharp. I'm not sure why I care about power supply aesthetics, as they're usually tucked deep within the bowels of your PC case, but I do.

And if they can provide some extra reassurance and prevent your precious graphics card from melting at a crucial point? Well, all the better. The PSUs also come with a 10-year warranty, which is an encouraging thing to see on any specs sheet.

Who knows where Gigabyte's Hardware Guardian might appear next? Is it a bird? Is it a plane? No, it's a box that powers your PC components. Sleep safe, citizens. If you pick up one of these, your graphics card might live to fight another day. Hopefully.
