Power-supply basics

The Thermaltake Smart BX3 PS-SPD-0750NNFABU-3 is a 750 W ATX 3.1 unit built for mainstream desktop builds. It delivers power through fixed cables and meets 80 PLUS Bronze efficiency at 115 V input.

Check your case and cables

Verify the chassis accepts a 150 mm long supply and that fixed 24-pin, dual 4+4-pin CPU, two 6+2-pin PCIe, four SATA and four peripheral leads reach every component. Confirm the mains inlet matches your local 100-240 V supply.

Build integration

The 12 cm FDB fan handles cooling while active PFC and full OCP, OVP, UVP, OPP, OTP, SCP protection guard the system. Fixed wiring removes modular connectors but keeps cable routing predictable inside the case.

Questions sur cet article

What cables come attached to the non-modular Smart BX3 750W and what must I add myself?

The unit ships with a fixed 24-pin main connector, two 4+4-pin CPU connectors, two 6+2-pin PCIe connectors, four SATA connectors and four peripheral connectors. No extra cables can be added because the PSU is non-modular.

The Smart BX3 line only lists one 750W model — how do I know this capacity fits my build?

With 750 W maximum output, 80 PLUS Bronze efficiency at 115 V, two 6+2-pin PCIe connectors and a 150 mm depth, it suits mid-range GPUs and standard ATX cases that accept that length.

What does the 80 PLUS Bronze at 115Vac rating mean for daily power draw?

It guarantees at least 80 % efficiency at typical loads when fed from a 115 V mains supply, reducing waste heat and lowering electricity cost compared with uncertified units.
