Model ATX 80+ Gold (650W)

  • 80 PLUS Gold certified for 90 to 92 percent efficiency
  • 150 mm length fits compact cases while delivering 650 W
  • Fully modular cabling keeps builds clean and airflow unobstructed
  • 130 mm hydraulic dynamic bearing fan runs quieter and lasts longer
  • Single +12 V rail supplies 54.1 A for stable GPU power

Compact 150mm ATX Power Supply

The EVGA SuperNOVA G3 delivers 650 W of fully modular ATX12V and EPS12V power in a 150 mm long chassis. It targets builders who need Gold-certified efficiency and a single +12 V rail for modern GPUs. The unit includes a 24-pin main connector, three 6+2-pin PCIe connectors and six SATA power connectors. It supports SLI and CrossFire multi-GPU configurations.

Replaces Bulkier Gold Units

This model reduces length compared to many standard ATX supplies while keeping 80 PLUS GOLD ratings of 90% at 115 VAC and 92% at 220-240 VAC. The jump is worthwhile when case space is limited or when cable routing benefits from full modularity. A 130 mm hydraulic dynamic bearing fan and EVGA ECO mode lower noise at light loads. Over-voltage protection guards connected components.

Straightforward Modular Install

Full modularity means only required cables are fitted, simplifying routing in tight builds. The included Power On Self Tester lets you verify the unit before mounting it in the case. Ensure the 150 mm depth clears your chassis and cable bends. Connect the 24-pin, EPS and PCIe cables firmly to avoid intermittent power delivery.

Questions about this item

What case depth is required for the 150 mm long SuperNOVA G3 unit?

The power supply measures 150 mm in length, so the case must provide at least that much clear depth behind the motherboard tray for the unit and its modular cables.

Which cables must be connected during installation, and which step is often missed?

Attach the 24-pin ATX motherboard cable, the 8-pin EPS CPU cable and any required 6+2-pin PCIe cables; the step most often missed is plugging the modular cables into the PSU side before routing them.

When should the 130 mm hydraulic dynamic bearing fan be cleaned or replaced?

Clean dust from the fan blades and intake vents every 6 to 12 months; replace the fan only if bearing noise appears or airflow drops noticeably.
