EVGA SuperNOVA 750 GA Power Supply

The EVGA SuperNOVA 750 GA is an ATX12V unit rated for 750 W maximum output. It targets system builders who need a fully modular Gold-rated supply in a compact 150 mm depth. The single +12 V rail design simplifies power distribution for modern graphics cards and CPUs. Japanese capacitors and a double-ball bearing fan support long-term reliability.

Fully Modular Cable Set

Every cable detaches from the unit so you install only the connections your build requires. The package provides a 24-pin main connector, six 6+2-pin PCI-Express leads and eight SATA power plugs. Removing unused cables reduces clutter and improves airflow inside the case. This flexibility suits both compact and full-size chassis layouts.

Sustained Load Behaviour

80 PLUS Gold certification guarantees at least 90 % efficiency at typical loads, limiting waste heat during extended sessions. The LLC resonant DC-to-DC topology maintains tight voltage regulation across the +3.3 V, 5 V and +12 V rails under continuous demand. ECO mode stops the fan entirely during low to medium workloads, delivering silent operation. The double-ball bearing fan engages only when thermal conditions require active cooling.

Questions about this item

What does the 750 W rating mean once the unit is installed in a real PC?

It represents the maximum continuous DC power the supply can deliver across all rails combined, so a system drawing up to 750 W total will stay within the unit's rated capacity.

How does the 80 Plus Gold certification cap real-world efficiency?

The certification guarantees at least 90 % efficiency at typical loads, meaning no more than 10 % of the AC power drawn is lost as heat under normal use.

What does the 150 mm length require for fitting and mounting?

The case must provide at least 150 mm of clear depth in the PSU bay, and the standard ATX mounting holes will align with the four screws on the unit's rear face.
