MSI MAG A750BN PCIE5 III — 750W ATX 3.1 Power Supply with Native 12V-2x6

750W 80 PLUS BronzeATX 3.1 · PCIe 5.112V-2x6 450W120mm hydraulic fan

The MSI MAG A750BN PCIE5 III is a 750W ATX power supply with 80 PLUS Bronze efficiency, ATX 3.1 / PCIe 5.1 support and a native 12V-2x6 (16-pin) GPU connector rated at 450W — aimed at gaming and everyday desktop builds that want a current-standard PSU without paying for modular cables.

It is a single +12V rail design (62.5A) with DC-to-DC conversion, active PFC and a 120mm hydraulic-bearing fan. The 12V-2x6 cable is dual-coloured with a yellow connector, so you can see when it is fully seated in the graphics card. The cables are fixed (non-modular) and use a flat, embossed jacket that is easier to route than round sleeved bundles.

Before you order: The cables are fixed, so every lead stays attached even if your build does not use it — plan space in the case for the unused ones. The PSU is standard ATX (140mm deep).

What's in the Box

  • MSI MAG A750BN PCIE5 III power supply with fixed (non-modular) cables
  • MSI does not publish an itemised box list for this model (power cord, screws and manual are not confirmed) — ask us if you need it checked before ordering

What It Means in Practice

  • A modern GPU with a 16-pin connector plugs straight in — no adapter needed up to 450W on that connector.
  • Two EPS 4+4 leads cover motherboards that need 8+8 or 8+4 CPU power.
  • 80 PLUS Bronze means up to 85% efficiency: fine for gaming systems; Gold units run cooler under constant heavy load.
  • The 200% power excursion rating means short GPU power spikes are absorbed as the ATX 3.1 spec requires.

What Will Not Work

  • It is not modular — you cannot remove unused cables or swap in custom cable kits.
  • It is ATX size; it will not fit SFX-only small form factor cases.
  • The 12V-2x6 connector is rated 450W; a GPU that needs more than that on the 16-pin connector needs a higher-wattage unit.
  • There are 3 PCIe 6+2 connectors and 3 SATA connectors only — builds with many drives may need splitters.

Frequently Asked Questions

Do I need an adapter for an RTX 40/50-series card?
Not for cards that use the 16-pin 12V-2x6/12VHPWR connector up to 450W — the cable is native.
Is 750W enough for my build?
Add the GPU board power to roughly 150-250W for CPU and platform; send us your CPU and GPU model and we will check the headroom.
Can I use custom sleeved cables?
No, the cables are fixed to the unit.
Singular Expert Insight · Buyer's Guide
The MAG A750BN PCIE5 III covers the essentials of a current gaming PSU — ATX 3.1, a native 16-pin GPU lead and Bronze efficiency — at a non-modular price point. Match the wattage to your GPU first: browse our graphics cards and check the board power the manufacturer recommends.
✓ Buy it if you are building or upgrading a gaming PC with a GPU of up to 450W on the 16-pin connector and want ATX 3.1 compliance.
✕ Skip it if you want modular cables, Gold/Platinum efficiency or an SFX-size unit.
→ Also consider the MSI MAG A650BN PCIE5 III if you need less wattage.
Not sure which wattage you need? Send us your CPU and graphics card model and we will check before you order.
