Shopping for pc power supplies & cables is not just a matter of choosing the lowest listed price. The key decision is whether your build calls for a modular cable approach, an SFX form factor, a particular condition, or a specific stated output. These four choices cover distinctly different priorities, from an Enermax unit described for multi-GPU rigs to compact SFX models and a non-modular ATX alternative.
Quick take
The listed-price span is $17.01, so the more meaningful split is configuration rather than a dramatic price jump. The Enermax MaxRevo is the 1350W modular choice with cables named in its title. EVGA pairs SFX and fully modular wording with a detailed connector list. Segotep is the lower listed-price option and carries a non-modular ATX description. Silver Stone is an SFX 80 Plus Bronze choice in used condition.
Listed price comparison
| Power supply | Listed price | Relative listed price |
|---|---|---|
| Enermax MaxRevo EMR1350EWT | USD 64.89 | |
| EVGA SuperNOVA 450 GM | USD 70.00 | |
| Segotep 650W ATX | USD 52.99 | |
| Silver Stone SST-ST45SF | USD 65.00 |
Decision matrix
- Compare stated output without assuming a winner: Enermax is listed at 1350W, Segotep at 650W, and both EVGA and Silver Stone at 450W. These are different specifications rather than automatic measures of suitability.
- For cable planning: Enermax includes cables in the title and has a modular design. EVGA is fully modular and names 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA, and 4 Pin Peripheral connections. Segotep is non-modular and lists a 20+4 Pin connector.
- For efficiency wording: Enermax, EVGA, and Segotep use 80 Plus Gold wording, while the Silver Stone title uses 80 Plus Bronze.
- For condition: EVGA is new, Segotep is open box, and the Enermax and Silver Stone entries are used.
Product notes
Enermax MaxRevo 1350W Modular PC Power Supply 80 PLUS Gold EMR1350EWT w/ Cables
The Enermax MaxRevo is the distinct choice when your build plan specifically calls for the title's 1350W output and a modular cable arrangement. Cables are named in the title, while the description identifies fully modular connectivity and six independent +12V rails. Its 80 PLUS Gold wording is another clearly stated part of the configuration. The tradeoff is condition: this is a used power supply. It is the most purpose-specific option for a shopper drawn to the description's multi-GPU and extreme-performance-system language, rather than someone simply seeking an SFX-format unit.
EVGA SuperNOVA 450 GM 450W 80 Plus Gold SFX Fully Modular Power Supply. New
The EVGA SuperNOVA 450 GM makes sense when the shortlist centers on an SFX unit with a fully modular design. Its connection types are spelled out clearly, including 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA, and 4 Pin Peripheral. That gives cable-focused shoppers a concrete set of named connections to weigh. ECO Mode with a DBB fan is also part of the description. The tradeoff is its stated 450W output, a different raw specification from the 650W and 1350W alternatives. Choose it for the SFX format and explicit connector list, not as a like-for-like replacement for every output category.
OPEN BOX 650W Power Supply 80 Plus Gold Non-Modular ATX Gaming PC Case PSU
The Segotep entry is aimed at shoppers seeking an ATX power supply with 80 Plus Gold wording and a listed 120mm fan. Its title and description consistently describe a non-modular configuration, and the attributes name a 20+4 Pin connector. The open-box condition is a separate point to factor into the choice. Its concrete limitation is the non-modular design: unlike the Enermax and EVGA models, it does not offer their stated modular cable setup. This makes it a clear pick for someone comfortable selecting an ATX, non-modular configuration rather than prioritizing detachable cable connections.
Silver Stone SST-ST45SF 450W SFX 80 Plus Bronze Power Supply
The Silver Stone SST-ST45SF is the straightforward route to the title's 450W SFX 80 Plus Bronze configuration. It suits a shopper whose shortlist is specifically an SFX power supply and who wants Bronze stated in the product name. The listed limitation is condition: it is used, and the description says it will show scratches from prior use. That detail matters more here than a cable-layout claim, since the product name emphasizes the SFX, 450W, and Bronze identifiers. Choose it for those named specifications, not for a promise of an untouched exterior.
Final recommendation by use case
- For a build described around multi-GPU capability: choose the Enermax MaxRevo; its description directly frames it for multi-GPU rigs and extreme-performance systems.
- For a new SFX choice with named connectors: choose the EVGA SuperNOVA 450 GM.
- When the lowest listed cost is decisive: choose the Segotep at USD 52.99, provided its non-modular ATX configuration matches your plan.
- For an SFX 80 Plus Bronze specification: choose the Silver Stone SST-ST45SF, while accounting for its used condition and noted scratches.
