EVGA SuperNOVA 450 GM: Is This 450W SFX Modular PSU Right for Your PC?

The EVGA SuperNOVA 450 GM is a 450W SFX power supply with a fully modular cable setup, 80 Plus Gold designation, ECO Mode, and a listed connector mix for compact PC builds.

Last updated Aug 24, 2026

Choosing among pc power supplies & cables comes down to more than wattage: a compact build may call for an SFX form factor, while a cleaner interior can make modular cabling a priority. The EVGA SuperNOVA 450 GM addresses both points, but its listed 450W output makes the decision most straightforward for shoppers already planning around that rating.

Quick verdict

The EVGA SuperNOVA 450 GM is a focused SFX power supply for a build that calls for a compact-format unit and individually chosen cables rather than a fixed cable bundle. At the listed price of USD 70.00, it combines a fully modular design with an 80 Plus Gold designation and ECO Mode with a DBB fan. Its appeal is specific rather than broad: choose it when 450W and SFX are the requirements already on your list.

Who it suits

This model makes sense for someone selecting an SFX-format power supply and wanting the cable set to include a 24-pin connector, 4+4 CPU connector, 6+2-pin PCI Express connector, SATA, and 4-pin peripheral connections. That connector lineup gives shoppers clear connection types to match against the parts already chosen for their PC.

The fully modular layout is also relevant for builders who want to use only the cables needed for their particular component set. That is a practical reason to look at the SuperNOVA 450 GM rather than treating every compact PSU as interchangeable.

What stands out from the listed details

The SFX form factor is the defining detail here, paired with a single-fan cooling arrangement and ECO Mode with a DBB fan. The 80 Plus Gold designation is another clearly stated part of the specification. Together, those details describe a compact, modular power-supply configuration rather than a cable-only purchase.

The connector list is unusually useful in a short specification because it names both primary PC connections and peripheral-oriented options. For a shopper mapping out cable needs in advance, that is more actionable than a general claim of broad connectivity.

Meaningful trade-offs

The main boundary is the 450W rating. Shoppers who have already decided they need a power supply with a higher listed wattage should move on rather than trying to stretch this choice beyond its stated configuration.

Price is another straightforward consideration. USD 70.00 buys the SFX format, modular cabling, ECO Mode, and the listed connectors, so it is best judged as a targeted purchase for those exact requirements-not merely as a generic replacement power supply.

Choose the EVGA SuperNOVA 450 GM when the combination of SFX form factor, fully modular cabling, and the named 24-pin, CPU, PCI Express, SATA, and peripheral connectors fits the build plan. The limitation is equally clear: its 450W output is a fixed part of the choice, so it does not answer a need for a higher-wattage unit.

Bottom line

The EVGA SuperNOVA 450 GM is a sensible match for a compact PC build centered on an SFX power supply and modular cable management. Its listed configuration is clear, and the decision is simple: pick it for its compact 450W modular setup, not as a catch-all solution for every PC.
