Thermaltake Toughpower GX3 SE 750W — 80 PLUS Gold ATX 3.1 PSU

750W ATX 3.180 PLUS Gold12V-2x6 600W5-year warranty

The Thermaltake Toughpower GX3 SE 750W (model TGS-0750AH2NLG) is an Intel ATX 3.1 power supply with 80 PLUS Gold efficiency of up to 90%, built for mid-to-upper gaming PCs running a PCIe 5.x graphics card with a 12V-2x6 connector.

All 750W is available on a single +12V rail (62.5A). It has a native 600W 12V-2x6 cable plus four PCIe 6+2 connectors, a 120mm fluid-dynamic-bearing fan tuned for quiet running, and OCP, OVP, UVP, OPP, SCP and OTP protection. Note that some listings call it "GX SE"; the official name is Toughpower GX3 SE.

Before you order: Input is 200–240V AC only (Cyprus/EU mains). Storage connectivity is modest — 3 SATA and 1 Molex — so count your drives before choosing it for a storage-heavy build.

What's in the Box

  • Toughpower GX3 SE 750W power supply
  • AC power cord
  • Mounting screws and documentation (contents not itemised by Thermaltake)

What It Means in Practice

  • Gold efficiency means less heat inside the case and lower fan noise than a Bronze unit at the same load.
  • The native 12V-2x6 cable connects directly to RTX 40/50-series cards — no adapter octopus.
  • Four PCIe 6+2 connectors also cover older cards that use two or three 8-pin plugs.
  • 750W comfortably suits a single mid-to-high-end GPU with a mainstream CPU.

What Will Not Work

  • It will not run on 110–120V mains.
  • Only 3 SATA and 1 Molex — a build with many SATA drives or fan hubs will need splitters or a different PSU.
  • Modularity is not published by Thermaltake — plan for fixed cables.
  • Flagship GPUs with 450W+ board power plus a high-end CPU are better served by 850W or more.

Frequently Asked Questions

Is 750W enough for an RTX 5070 Ti or 4080?
For a single card of that class with a mainstream CPU, yes. Send us your exact parts and we will confirm the headroom.
Why only 3 SATA connectors?
Thermaltake specifies 3 SATA and 1 Molex for this model. Most modern builds use M.2 SSDs, which need no PSU cable.
Is it the same as the Toughpower GX3?
It is the SE (special edition) variant of the GX3 family with its own connector set; use the specifications above for this exact part.
Singular Expert Insight · Buyer's Guide
The GX3 SE 750W is the step up from Bronze for builders who want Gold efficiency and a native 12V-2x6 cable without paying for full modularity. Compare wattages and efficiency classes in our PC power supplies range.
✓ Buy it if you want a quiet, efficient 750W ATX 3.1 unit for a single modern graphics card.
✕ Skip it if you run many SATA drives, need modular cables or plan a flagship GPU.
→ Also consider an 850W Gold unit if you plan to upgrade to a top-tier graphics card later.
Unsure about wattage? Send us your CPU and GPU model and we will size it before you order.
