MSI launches new MAG GL series ATX 3.0 power supplies with innovative dual-colour 12VHPWR connectors

MSI launches their first PSUs with dual-colour 12VHPWR connectors that help prevent incorrect cable insertions

Most PC enthusiasts will be aware of the “burning 12VHPWR” cable issues that plagued many GeForce RTX 40 series GPU users in 2022, a problem that was later found to be caused by users incorrectly inserting 12VHPWR/12+4-pin/16-pin power cables into graphics cards, power supplies, or both. This problem primarily affected users of Nvidia’s RTX 4090 graphics cards, as that GPU’s high power draw when combined with an incorrectly inserted 12VHPWR cable can cause the cable to heat up and melt during use, a problem that can be avoided by making sure that your cables are seated fully/correctly.

At Computex, MSI has revealed a novel solution that should help ensure that none of their users are affected by this issue moving forward. This solution is now available with the launch of MSI’s new ATX 3.0 certified MAG GL series of power supplies, which is now available in 850W, 750W, and 650W forms.

With their new MAG GL series of PCIE5 ATX 3.0 power supply, MSI are supplying coloured 12VHPWR connectors that use bright yellow plastic terminals. This coloured plastic is only visible when the cable is not fully connected to the 12VHPWR connector on your power supply or graphics card, allowing users to easily spot if their cables are incorrectly seated.

This unique design feature should help avoid PC gamers from running into any “melted 12VHPWR” connection issues, a factor that will likely make these coloured connection terminals a common feature for many power supplies moving forward. These coloured connections are not visible when cables are correctly inserted, which means that this design feature has not negative impact on a gaming PC’s aesthetics, but it can be a lifesaver when it comes to avoiding avoiding connection issues.

With a compact 140mm x 150mm x 86mm size, MSI’s new MAG GL series PSUs are great options for compact Micro-ATX PC cases, and their 80+ Gold Efficiency rating ensures that minimal power is wasted during the PSU’s AC to DC conversions. Below is what MSI has to say about their new MAG GL series of ATX 3.0 PSUs.

PRESS RELEASE – MSI Announces the MAG GL Series ATX 3.0 Power Supplies

The latest MAG GL Series power supply unit series helps complete MSI’s offering of PCIe 5.0 ready power supply units across its entire lineup, besides being ATX 3.0 compatible and PCIe 5.0 ready with native 16 Pin connectors designed in yellow to improve assembly identification. This is an 80 Plus Gold certified power supply unit that is fully modular, single-railed with DC to DC structure. Just from the mentioned features alone, you can tell that it is a power supply unit designed to fully tackle the latest high-performing graphics cards while maintaining a stable supply of power. The power supply is 140x150x86 mm, which means it can also easily fit in most of the micro-ATX chassis.

The MAG GL series ATX 3.0 power supply which fully supports NVIDIA GeForce 40 series graphics cards and complies with PCIe 5.0 and Intel PSDG (Power Supply Design Guide) ATX 3.0 standard. ATX 3.0 standard means the power supply can hold up to 2x total power excursion and 3x GPU power excursion while using native 16 Pin PCIe connectors that can pipe up to 600 W of power and reduce the use of adapters, optimizing assembly space. Now MSI ATX 3.0 power supplies are across the entire series, offering many options for choosing the power supply they need. (MAG A850GL PCIE5 and MAG A750GL PCIE5 only).

MSI Dual-color 16-pin cable

Examining the reported cases of power supply connectors being burnt when paired with high-end graphics cards, we’ve identified the main reason: the connectors not being plugged in properly and the connector pins suffering from fallouts. With this new cable, we successfully tackle both issues head-on.

The cable’s connector color has been changed to yellow so that users can easily see if the connector has been plugged in properly. Besides, the MSI patented pending Dual-color 16-pin cable also won Wccftech awards in the 2023 COMPUTE
