MSI MAG A750GL PSU Review: Strong Value, Minor Flaws
The MSI MAG A750GL Gaming Power Supply (750W, 80 Plus Gold, Full Modular) has earned a strong 4.7/5 average across multiple platforms, but digging into the details reveals a more nuanced picture. While many users praise its compact size, modern PCIe 5.0 readiness, and stable performance, there’s a recurring thread of criticism around cable stiffness and occasional fan noise. For builders prioritizing clean cable management, modern GPU support, and reliable mid-range wattage, it’s a compelling option—but those chasing absolute silence or ultra-flexible cables might find it less than perfect.
Quick Verdict: Conditional — Excellent for mid-range to high-end gaming builds needing PCIe 5.0 readiness, but fan noise and cable stiffness may bother silence-focused users.
| Pros | Cons |
|---|---|
| Compact ATX size (140mm depth) fits tight cases | Cables are stiff and hard to route |
| Fully modular with flat cables | Fan noise noted by some users |
| Native 12VHPWR PCIe 5.0 cable included | 24-pin PSU connector design awkward for some cases |
| Stable power delivery, no coil whine reports | SATA cable length excessive for single-drive setups |
| 80 Plus Gold efficiency | Isolated reports of early fan failure |
| Good value under $100 USD | Limited headroom for future high-wattage GPU upgrades |
| Supports RTX 40/50 series GPUs |
Claims vs Reality
MSI markets the MAG A750GL as ATX 3.1-ready with native PCIe 5.1 support, capable of up to 2x total power excursion and 3x GPU power excursion. On paper, this makes it a future-proof choice for RTX 40-series cards. Users confirm this capability: a Best Buy reviewer powering a Ryzen 9800X3D and RTX 5070 noted it had “plenty of headroom for future upgrades” and appreciated the native 12VHPWR cable, removing the need for adapters.
The brand also emphasizes its compact size for easier cable management. In practice, while the shorter depth does help in small cases, multiple PCPartPicker users complained that “the cables were really beefy and somewhat hard to position,” making rear panel closure difficult. This suggests that while the PSU’s body is compact, cable flexibility hasn’t matched that design goal.
Finally, MSI promotes a quiet fluid dynamic bearing fan. Many buyers agree it’s quiet under load, with one Best Buy customer calling it “super quiet… no power drops, solid power output.” However, Redditors and PCPartPicker reviewers occasionally report that “it’s always the loudest thing in my silent system” or that fan noise increases over time—one Best Buy user claimed the fan became “horrifically noisy in 3 months” across three units.
Cross-Platform Consensus
Universally Praised
Across Amazon, Reddit, and Best Buy, stability and reliability come up repeatedly. A Quora reviewer lauded its “stable power delivery… no coil whine, no reboots, no crashes” even under heavy gaming loads like MS Flight Simulator 2024. Users running modern GPUs such as the RTX 4070 Ti Super or 5070 confirm it handles them without issue. The fully modular design resonates strongly, freeing builders to “only use what you need” and store extras in the included pouch—something several Best Buy reviewers appreciated for keeping spare cables organized.
The price-to-performance ratio is another highlight. PCPartPicker builders repeatedly call it “a great bang for the buck” and “probably the best $90 I spent.” A Redditor summed it up: “MSI MAGs are one of the best PSUs… the 5070 Ti 750 is enough.” For small form factor enthusiasts, its 140mm depth is a major win. One Quora user noted it “fit amazingly well in this SFF case… improved airflow from the bottom intake.”
Common Complaints
The most consistent criticism is cable stiffness. Newegg buyers call the wires “thicc” and “a pain to plug into the PSU itself,” while PCPartPicker users mention struggling to position the 24-pin motherboard cable. Even the otherwise positive Quora review warns to “be careful bending [the 12VHPWR] into position—let it curve naturally.”
Fan noise appears in multiple contexts. While many call it quiet, some silent-PC builders find it intrusive. One Redditor said it’s “always the loudest thing” in their system, and a PCPartPicker reviewer replaced it entirely with a Noctua P12 to reduce noise. A more troubling pattern is from a Best Buy user who claims they’ve had three units develop loud fan issues after ~3 months, suggesting a possible QC concern, though this is not widely echoed.
Minor annoyances include awkward connector design—the 24-pin splits on the PSU side, requiring two separate insertions—and overly long SATA power chains when only one drive is needed.
Divisive Features
The always-on fan divides opinion. Some appreciate the constant low-speed cooling, while others miss an eco/hybrid mode for passive operation under low load. Aesthetic minimalism is another split—no RGB appeals to those wanting a clean look, but RGB enthusiasts may see it as a missed opportunity.
On wattage headroom, mid-range users find 750W more than enough; one Best Buy reviewer running a 4070S/i5-14400 combo said it “runs great so far.” But others warn it leaves “minimal room to upgrade” beyond a 4070 Ti-class GPU, suggesting higher wattage for those eyeing top-tier cards.
Trust & Reliability
Long-term reliability feedback is largely positive. Users report months of stable operation with no crashes, and multiple reviewers mention other MAG series PSUs running for years without issue. A PCPartPicker builder said their 650W MAG “has been good for ~2 years now” alongside the new 750W.
However, the isolated recurring fan failure report from Best Buy—three units in a row—raises questions. While it’s unclear if this is a batch issue, prospective buyers who value absolute silence should monitor early-life fan behavior.
No patterns of outright DOA units, electrical faults, or safety incidents emerged across platforms, and the 5-year manufacturer warranty offers a safety net.
Alternatives
When compared to Corsair’s RM series, several buyers note the MAG A750GL is “cheaper than other mainstream ones like Corsair” while offering similar efficiency and features. A Micro Center employee reportedly recommended it over a Corsair 750E as it was $10 less and “seems just as good if not better.” The higher-wattage MSI MAG A850GL has been reviewed by HWBusters and received positive notes for price/performance, making it a logical step-up for those needing more future GPU headroom.
Price & Value
At the time of reporting, eBay listings show it around $93.99 USD new, Newegg Canada offers it at $159.99 CAD, and Best Buy has sold it for $96.99 USD—well below its $109.99 MSRP. The community consensus is that it’s an excellent buy under $100, especially for builds that will leverage the native PCIe 5.0 cable. Resale activity exists but is modest, suggesting most buyers keep it long-term rather than flipping.
FAQ
Q: Is 750W enough for an RTX 5070 Ti build?
A: Yes. Multiple users power RTX 4070 Ti and similar GPUs without issue. A Redditor confirmed 750W is sufficient for a 5070 Ti, with power headroom to spare.
Q: Does it have a native 12VHPWR connector?
A: Yes, it includes a 16-pin PCIe 5.0 cable capable of delivering up to 450W to modern GPUs, removing the need for adapters.
Q: Is the fan noisy?
A: Most users find it quiet, but a subset—especially silence-focused builders—report it as the loudest component. One buyer replaced the fan entirely for quieter operation.
Q: Will it fit in small cases?
A: The 140mm depth is shorter than many ATX PSUs, allowing it to fit in tighter builds and improve airflow.
Q: Are the cables easy to work with?
A: Not particularly. Many buyers find them stiff, especially the 24-pin and 12VHPWR, making cable routing challenging in compact cases.
Final Verdict: Buy if you’re building a mid-range to high-end gaming PC with modern GPU needs and value efficiency, stability, and modular design. Avoid if silent operation is your top priority or if you need ultra-flexible cables in a cramped case. Pro tip: Aim to grab it under $100, where it’s widely regarded as one of the best value modular Gold-rated PSUs in its class.
