What the G+ delivers

The EVGA SuperNOVA 650 G+ is a fully modular ATX power supply rated at 650 W with 80 PLUS Gold efficiency. It uses a single +12 V rail, 100 % Japanese capacitors and a 135 mm Fluid Dynamic Bearing fan. The unit measures 170 mm long and includes a Power ON Self Tester for quick checks before installation.

Who should choose it

System builders who need a compact, fully modular 650 W unit with Gold efficiency and a ten-year warranty will fit this PSU easily. Anyone requiring higher wattage, a different efficiency tier or a shorter depth than 170 mm should consider other models instead.

The deciding specification

The critical figure is the 650 W maximum power combined with a single +12 V rail rated at 54 A. If your build’s total power draw stays within that limit, the G+ will deliver stable voltage; if it exceeds 650 W, you must select a higher-capacity unit.

Questions about this item

Does my case need to accept an ATX power supply up to 170 mm long?

Yes, the unit is 170 mm deep, so the case must support that length.

Can I reuse my older SATA drives and PCIe graphics cards with the included cables?

The box provides 9 SATA power connectors and 4 PCIe 6+2-pin cables for those devices.

How do I confirm the unit is working before installing it in the case?

Use the included Power ON Self Tester on the 24-pin connector to verify the PSU starts and delivers power.
