650 W ATX12V power supply

The ASUS TUF GAMING 650B delivers 650 W through a single +12 V rail rated at 51 A. It uses a non-modular ATX12V design with a 150 mm depth and an 80 PLUS Bronze efficiency rating. A 135 mm dual ball bearing fan with Axial-tech blades and 0dB Technology handles cooling.

Suits mid-range builds needing fixed cables

This unit fits builders who want military-grade capacitors, a protective PCB coating and a six-year warranty in a 650 W Bronze package. The fixed cable set includes two PCIe 6+2-pin and five SATA connectors. Systems requiring fully modular cabling or higher wattage should consider other models.

Single +12 V rail at 51 A

The +12 V rail supplies 51 A, which determines whether the PSU can power your graphics card and CPU together. Check your components' combined 12 V current draw against this 51 A limit before purchasing.

Questions about this item

Which capacity should I choose for a mid-range build with one graphics card?

The 650 W unit delivers up to 51 A on the single +12 V rail, enough for a modern CPU and a single high-end GPU without needing a higher-wattage model.

What does the 80 PLUS Bronze label mean for daily use?

It certifies the supply meets Bronze-level efficiency targets at 20 %, 50 % and 100 % load, reducing waste heat and lowering electricity draw versus uncertified units.

How many PCIe power connectors does the non-modular cable set include?

Two 6+2-pin PCIe connectors are permanently attached, supporting most graphics cards that require one or two 8-pin plugs.
