MSI
MSI has made a bold statement in the power supply unit (PSU) market with its latest high-end offerings, the MPG A1000GS and MPG A1250GS. These new PSUs are ditching the familiar 8-pin power connectors in favor of multiple 12V-2×6 sockets, a move that’s raising eyebrows—and compatibility concerns—among PC enthusiasts. Is this a sign of a seismic shift in the PSU industry, or just a niche experiment for a specific audience? Let’s break it down.
A Break from Tradition
Power connectors are the unsung heroes of any PC build, delivering the juice that keeps CPUs, motherboards, and graphics cards humming. For years, the 8-pin connector has been the go-to standard for powering GPUs, with most modern PSUs—like the Corsair RM750X—offering two or three of them as a matter of course. But MSI is flipping the script. Its new MPG A1000GS and MPG A1250GS PSUs come with just one 8-pin socket, supplemented by two 12V-2×6 connectors.
The 12V-2×6, an evolution of the controversial 12VHPWR connector introduced with Nvidia’s RTX 30-series GPUs four years ago, is designed to handle higher power loads through a single, compact cable. While it’s gained traction with Nvidia’s latest cards, its adoption elsewhere has been sluggish—until now. MSI’s decision to prioritize it over the trusty 8-pin is a radical departure from industry norms.
Compatibility Concerns for AMD and Intel GPUs
This shift isn’t without consequences. Many high-end graphics cards from AMD and Intel—like the Radeon RX 7900 XTX or Intel Arc A770—rely on multiple 8-pin connectors to meet their power demands. With only one 8-pin socket available, users of these GPUs might find themselves scrambling for adapters or alternative PSUs to keep their rigs running. For gamers and professionals outside Nvidia’s ecosystem, this could be a frustrating limitation.
Meanwhile, Nvidia’s RTX 40-series GPUs, which natively support the 12V-2×6 connector, pair seamlessly with MSI’s new PSUs. But for everyone else, this move feels like a gamble that might not pay off.
The AI Factor: Why Two 12V-2×6 Sockets?
So, what’s driving MSI’s decision? The answer lies beyond gaming—in the booming world of AI and machine learning. While dual-GPU setups like SLI have faded from the gaming scene, they’re making a comeback for AI workloads, such as training models and running inference tasks. Nvidia GPUs, which dominate this space, increasingly use the 12V-2×6 connector, and MSI’s dual 12V-2×6 sockets are tailor-made for these power-hungry configurations.

This isn’t a snub to AMD or Intel users—it’s a strategic play to cater to a growing niche of AI enthusiasts and professionals who need robust power delivery for multi-GPU setups. MSI isn’t abandoning traditional designs entirely, though; it still offers PSUs with up to three 8-pin connectors alongside a 12V-2×6 option for those who need them.
A Glimpse into the Future of Power Connectors?
MSI’s move sparks a bigger question: Is the 8-pin connector on its way out? The 12V-2×6 has had its share of drama—early safety concerns at high power loads made headlines—but it’s proven reliable at moderate demands (around 300W). Its single-cable design is also a win for system builders, simplifying assembly and cutting costs compared to wrangling multiple 8-pin connectors. When you’re churning out thousands of PCs, those savings add up.
Still, the PSU market is a crowded space, brimming with options for every need. Traditional 8-pin-heavy PSUs aren’t going anywhere fast, and the 8-pin connector’s demise feels a long way off—think a decade or more. Remember the Molex connector? It’s all but vanished from modern builds, but that transition took years. The 8-pin is likely to follow a similar slow fade, not an abrupt exit.
What This Means for Consumers
For most PC builders, MSI’s new PSUs won’t upend their plans. The market is flush with alternatives sporting multiple 8-pin sockets, ensuring compatibility with any GPU. But MSI’s pivot hints at where the industry might be headed. As AI becomes more mainstream, we could see more PSUs optimized for these workloads, with the 12V-2×6 connector leading the charge.
For now, this feels like a targeted experiment—a niche offering for a small but growing audience. MSI isn’t forcing a revolution; it’s testing the waters. Whether other manufacturers follow suit or stick to the tried-and-true remains to be seen.
The Bottom Line
MSI’s latest PSUs are a daring leap, embracing the 12V-2×6 connector in a way that’s bound to turn heads. It’s a boon for AI-focused builds and Nvidia loyalists, but a potential headache for AMD and Intel GPU users. While it’s too early to call this the new standard, it’s a clear signal that MSI is ready to push boundaries in a competitive market. For tech enthusiasts, it’s a development worth watching—preferably with a fully powered GPU by your side.
