Thermaltake Smart BX3 Pro SE 750W — ATX 3.1 Bronze PSU with native 12V-2x6

750W ATX 3.180 PLUS Bronze12V-2x6 600W5-year warranty

The Thermaltake Smart BX3 Pro SE 750W (SPS-0750AH2NLB-3) is an Intel ATX 3.1 power supply rated at 750W continuous with 80 PLUS Bronze efficiency, aimed at gaming and workstation builds that use a current PCIe 5.x graphics card with a 12V-2x6 (12+4-pin) power connector.

It delivers its full 750W on a single +12V rail (62.5A) with DC-to-DC conversion for the 3.3V and 5V outputs, uses low-profile flat black cables and a 120mm fluid-dynamic-bearing fan, and carries the usual protection set: OCP, OVP, UVP, OPP, OTP and SCP. Efficiency is up to 88% at 230V.

Before you order: Input is 200–240V AC only, which suits Cyprus and EU mains. It is not a wide-range 100–240V unit, so it is not suitable for 110–120V mains.

What's in the Box

  • Smart BX3 Pro SE 750W power supply
  • AC power cord
  • 4 mounting screws
  • User manual

What It Means in Practice

  • A single native 12V-2x6 cable powers an RTX 40/50-series or similar GPU directly, without the four-plug adapter.
  • The 62.5A single rail means all +12V capacity is available to the GPU and CPU without rail-balancing.
  • Flat cables are easier to route behind the motherboard tray in compact ATX cases.
  • Thermaltake documents a Smart Zero Fan mode, so the fan only starts above a set temperature at light load.

What Will Not Work

  • It will not run on 110–120V mains (input is 200–240V only).
  • Modular cabling is not clearly published — plan the build assuming cables cannot be removed.
  • With 2 PCIe 6+2 plus one 12V-2x6, it cannot feed two high-end GPUs.
  • It is a standard ATX unit and will not fit SFX-only small-form-factor cases.

Frequently Asked Questions

Do I need an adapter for an RTX 4070/4080/5070?
No. The 12V-2x6 cable connects directly to cards with a 12VHPWR or 12V-2x6 socket.
Is it fully modular?
Thermaltake does not clearly publish modularity for this model, so treat the cables as fixed when planning cable management.
Bronze vs Gold — does it matter?
Bronze wastes slightly more energy as heat at the same load. For a gaming PC used a few hours a day the cost difference is small; for 24/7 machines Gold or better pays back faster.
Singular Expert Insight · Buyer's Guide
A sensible value pick for a modern GPU build: native 12V-2x6, ATX 3.1 and a 5-year warranty at Bronze pricing. If you want quieter running and modular cables, step up to a Gold unit from our PC power supplies range.
✓ Buy it if you are building or upgrading a gaming PC around a PCIe 5.x graphics card and want a straightforward ATX 3.1 unit.
✕ Skip it if you need modular cables, a small SFX unit or 110V support.
→ Also consider a fully modular 80 PLUS Gold 750W unit for quieter, tidier builds.
