Manufacturer description

The EVGA SuperNOVA 850 GT delivers 850W of 80 PLUS Gold power in a compact 150mm chassis, so it drops into mid-tower and small-form-factor builds where longer units won't clear the drive cage. Efficiency is rated at 90% or higher on 115VAC and 92% on 220-240VAC under typical loads, which means less waste heat inside your case and a quieter machine overall. The fully modular cable set lets you connect only the leads your build actually needs, clearing airflow paths in front of the intake. Inside, EVGA uses 100% Japanese capacitors backed by OVP, UVP, OCP, OPP, SCP, and dual OTP protection…

SpecPicks Verdict

SpecPicks scored EVGA 850 GT, 80 Plus Gold 850W, Fully Modular, Auto Eco Mode with… 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 850W enough for an RTX 4080 or similar high-end build?

850W covers most single-GPU builds in the 4080 class with headroom for an 8- to 16-core CPU. For a 5090-tier card plus an overclocked CPU, size up. Confirm your GPU maker's PSU recommendation before buying.

Will the EVGA 850 GT fit in a small form factor case?

It uses a compact 150mm depth, shorter than many 850W units, which helps in mid-towers and tight SFF chassis. It is a standard ATX unit, not SFX, so verify your case accepts ATX power supplies.

How long is the warranty on this power supply?

EVGA lists a 7-year warranty on the 850 GT (model 220-GT-0850-Y1). Registration and coverage terms can change, so check the current product listing and EVGA's warranty page before you buy.

What does Auto ECO Mode actually do?

Auto ECO Mode keeps the fluid dynamic bearing fan off at low and moderate loads, so the PSU runs silent at idle and during light gaming, then spins up as draw increases. FDB bearings also last longer than sleeve-bearing fans.
