Manufacturer description

It is 80 Plus Gold certified, holding 90 percent efficiency at 115VAC and up to 92 percent at 220-240VAC under typical loads, so less of what you pull from the wall turns into waste heat inside your case. EVGA lists 100 percent Japanese capacitors, tighter 12V load regulation, and a chassis up to 20mm shorter than the outgoing G1 line, which gives you more cable room in compact mid-tower builds. A 135mm fluid dynamic bearing fan handles cooling and is rated up to 20 percent quieter than the previous generation. Full protection circuitry covers OVP, UVP, OCP, OPP, SCP, and OTP. EVGA backs…

SpecPicks Verdict

SpecPicks scored EVGA SuperNOVA 120-GP-0650-X1 using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. EVGA's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Is 650W enough for an RTX gaming build?

650W comfortably covers most single-GPU mid-range builds. For high-draw flagship cards, check the GPU maker's recommended PSU wattage before ordering.

How long is the warranty on the EVGA 650 G+?

EVGA lists a 10 year warranty on this unit (model 120-GP-0650-X1). Confirm registration requirements on the current product listing.

Is this power supply fully modular?

Yes. Every cable detaches, including the 24-pin, so you only install the leads your build actually needs and route the rest out of the case.

What does 80 Plus Gold actually save me?

It certifies 90 percent efficiency at 115VAC and 92 percent at 220-240VAC under typical loads, meaning less draw wasted as heat inside your chassis.

What is the Power ON Self Tester included in the box?

It is a small jumper tool that lets you power the supply outside a system to verify it runs, useful for bench testing before you wire up a full build.

How loud is the fan?

It uses a 135mm fluid dynamic bearing fan that EVGA rates up to 20 percent quieter than the previous G1 generation. No dBA figure is published in the listing.
