Manufacturer description

The EVGA 450 BR is a 450W ATX power supply built for budget desktop builds and entry-level gaming rigs that need dependable rails without paying for headroom they will never use. Its 80 Plus Bronze certification means it holds 85% efficiency or higher under typical loads, so less of the wall draw turns into waste heat inside your case. EVGA backs the 450 BR with a full protection suite - OVP, UVP, OCP, OPP, SCP and OTP - which guards your motherboard, drives and GPU against over-voltage, over-current and short-circuit events rather than leaving them exposed on a cheaper unit.

SpecPicks Verdict

SpecPicks scored EVGA 100-BR-0450-K1 450 BR 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.

Frequently Asked Questions

Is 450W enough for a gaming PC?

450W of continuous power suits 1080p builds with a mid-range CPU and a single modest GPU. The unit provides two PCIe connectors, but check your specific GPU's rated PSU requirement before buying, since high-draw cards exceed this budget.

Is the EVGA 450 BR modular?

No. The 450 BR ships with fixed, non-detachable cables, so unused leads have to be routed and tucked behind the motherboard tray rather than left off the unit entirely.

What does 80 Plus Bronze actually mean here?

It certifies that the supply runs at 85% efficiency or higher under typical loads, so roughly 15% of the wall draw is lost as heat instead of reaching your components. Higher tiers lose less, but cost more per watt.

How long is the warranty on this power supply?

EVGA lists a 3-year warranty on the 450 BR. Registration requirements and regional terms vary, so confirm the current coverage details on the product listing before you buy.

Will the cables reach in a full-size mid-tower case?

Most layouts are fine. The ATX cable is 550mm, EPS is 600mm, PCIe leads run 550mm and 670mm, SATA reaches 690mm, four-pin peripheral reaches 810mm, and the AC cord is 1200mm.
