AI Verdict

This 750W 80+ Bronze semi-modular ATX power supply with a 120mm sleeve bearing fan is for budget builds needing basic power delivery.

Situational Fit

This 750W 80+ Bronze semi-modular power supply is a situational fit, offering adequate power and protection for entry-to-mid-range systems at a competitive price. Its 140mm depth is a plus for smaller cases, but the semi-modular design and potential fan noise under load might not suit everyone. It's a compromise for budget builds.

If you need quieter operation or superior cable management, look for power supplies with a fully modular design and a fluid dynamic bearing (FDB) fan, or an 80+ Gold rating for better efficiency.

Pros

  • Provides 750 watts of power, suitable for many gaming systems.
  • Features industrial-level protection including OVP, OCP, OPP, OTP, and SCP, safeguarding components.
  • Includes a 5-year limited warranty for parts and labor.
  • Semi-modular design allows for some cable management flexibility by detaching unused cables.
  • Compact 140mm depth fits in smaller ATX cases.

Cons

  • 80 Plus Bronze certification offers lower efficiency compared to Gold or Platinum rated units.
  • Semi-modular design means essential cables are permanently attached, potentially complicating cable management.
  • 120mm sleeve bearing fan can be louder than expected under load, according to some users.
  • Cable lengths might be short for larger PC cases, requiring creative routing.
  • Only provides two 6+2-pin PCIe connectors, potentially limiting options for high-end graphics cards that prefer two dedicated cables.

Dimension Scores

Efficiency & Output5/10

The 80+ Bronze rating is average for the category, providing 750W but not top-tier efficiency.

Noise Level4/10

While advertised as low-noise with a 120mm fan, some users report it can be louder under load, indicating it's not a silent option.

Build Quality5/10

User feedback suggests the build quality is 'decent' but not 'premium,' aligning with its entry-level price band.

Cable Management5/10

The semi-modular design offers some flexibility, but permanently attached cables and potentially short lengths for larger cases limit optimal management.

Best For

  • Budget-conscious PC builders needing 750W for a mid-range gaming system.
  • Compact ATX builds where a 140mm deep power supply is beneficial.
  • Users prioritizing essential protection features over peak efficiency.
  • First-time builders looking for an easy-to-install power supply.

Not Recommended For

  • High-end PC builds with multiple power-hungry components or extreme overclocking.
  • Silent PC enthusiasts who require near-inaudible operation under load.
  • Builders demanding fully modular cabling for pristine aesthetics and maximum flexibility.

Watch Out For

  • The 120mm sleeve bearing fan, while labeled 'low noise,' has been reported by some users to become louder under load.
  • Cable lengths may be too short for larger cases, making routing challenging and potentially requiring extensions.
  • Despite having two 6+2-pin graphics connectors, the unit may only come with one PCIe cable featuring both connectors, which can be suboptimal for high-end GPUs that benefit from two separate cables.
  • Some users have reported issues with customer service regarding warranty claims, despite the 5-year coverage.

What Buyers Say

This MSI 750W power supply often gets picked up for budget builds, with users finding it easy to install and appreciating its basic functionality. However, the semi-modular cabling can be a bit of a pain for neat freaks, and some folks have noticed the fan isn't as 'low-noise' as advertised when the system is really working hard. The 80+ Bronze rating is okay, but it's definitely not going to win any awards for efficiency or premium feel. It's a 'get the job done' kind of unit, but don't expect any frills.

“Look, it's 750 watts and it works, but don't expect it to be super quiet or have those fancy fully modular cables. For the price, it's fine, just wish the fan didn't spin up so much when I'm gaming hard.”

Common Praise

  • Provides stable power delivery for systems.
  • Easy to install in a PC build.
  • Includes comprehensive industrial-level protection features.
  • Offers a 5-year warranty, providing peace of mind.
  • Compact 140mm depth is beneficial for smaller case compatibility.

Common Complaints

  • Fan noise can be noticeable under heavy system load.
  • Semi-modular design leaves some cables permanently attached, making cable management less clean.
  • Cable lengths may be too short for larger PC cases.
  • Only one PCIe cable with two connectors, which isn't ideal for all high-end GPUs.
  • Build quality is considered adequate but not premium.

Ownership Tips

  • The permanently attached CPU and motherboard cables can be stiff, making routing behind the motherboard tray a bit of a struggle in tighter cases.
  • Under sustained gaming sessions, the fan becomes audible, not distracting, but definitely not silent.
  • The included SATA power cables are long enough for multiple drives, but the spacing between connectors can be tight for drives spread far apart.
  • The 140mm depth is genuinely helpful for cases with limited PSU clearance, making installation smoother than expected.
  • The 6+2 pin PCIe connectors are on a single cable, which means if your GPU needs two separate power inputs, you're daisy-chaining, which some people try to avoid.

Frequently Asked Questions

Is this power supply fully modular?

No, the MSI MAG A750BE is a semi-modular power supply. This means essential cables like the 20+4-pin ATX and CPU power cables are permanently attached, while others are detachable.

What is the efficiency rating of this power supply?

It is 80 Plus Bronze certified, which means it meets a certain standard for power efficiency, converting at least 82% of AC power into DC power at 20% load, 85% at 50% load, and 82% at 100% load.

How many PCIe connectors does it have for a graphics card?

The power supply features two 6+2-pin PCIe graphics connectors. However, some users note it might come on a single cable, which is something to consider for high-power GPUs.

What is the warranty period for this power supply?

The MSI MAG A750BE comes with a 5-year limited warranty for both parts and labor.

Is this power supply quiet?

It features a 120mm low-noise sleeve bearing fan. While generally quiet, some users have reported it can become louder than expected when the system is under heavy load.

Buying Guide

When you're looking at a power supply, you're basically buying the heart of your PC. It takes the wall power and converts it into usable power for all your components. You need to make sure it can supply enough wattage for everything you've got, and that it does it efficiently without wasting a ton of electricity as heat. Also, how the cables connect matters a lot for how clean your build looks and how easy it is to put together.

Wattage (750W)

This is the total power your PSU can deliver. Think of it like the horsepower of a car; if your engine (PC components) needs 700 horsepower, a 750W PSU gives you just enough headroom. Too little, and your PC won't run stably or might not even turn on. Too much, and you're paying for power you don't use, though it leaves room for future upgrades.

80 Plus Bronze

This certification tells you how efficient the power supply is at converting AC power from your wall into DC power for your PC. Bronze is like getting decent gas mileage – it's better than nothing, but not the best. Higher ratings (Gold, Platinum, Titanium) mean less wasted electricity as heat, which can save you a bit on your power bill and keep your PC cooler.

Semi-Modular

This refers to the cables. 'Semi-modular' means the essential cables (like the ones for your motherboard and CPU) are permanently attached, but you can plug in or unplug other cables (for your graphics card, hard drives) as needed. It's a middle ground between 'non-modular' (all cables attached) and 'fully modular' (all cables detachable), offering some flexibility for tidier builds without the higher cost of fully modular.

Active PFC Design

PFC stands for Power Factor Correction. Active PFC helps the power supply draw power from the wall more efficiently and reduces electrical noise. It's like having a smart charger for your phone that optimizes how it pulls power, making it more stable and less disruptive to your home's electrical system.

Alternatives

If this PSU doesn't quite hit the mark, look for models with an 80+ Gold certification for better efficiency, a fully modular design for superior cable management, or a fluid dynamic bearing fan for quieter operation.
