Shopping for pc power supplies & cables starts with one important fork: are you replacing the SFX power supply itself, or adding sleeved extensions to an existing cable layout? The three power supplies share SFX wording but differ in stated output, condition, efficiency labeling, connector detail, and modular designation. Asiahorse addresses the cable-extension side instead. Separate those two jobs first, then focus on the exact labels that matter for your build.
Quick take
The EVGA SuperNOVA 450 GM is the clear match for someone seeking a new-condition unit with a fully modular feature. The SilverStone SST-ST30SF is the only 300W model here, while the Silver Stone SST-ST45SF pairs 450W with 80 Plus Bronze wording. Asiahorse is the cable-focused pick, bringing Snow White sleeved extensions into the comparison. Across all four selections, the listed-price spread is $37.10.

Decision matrix
- EVGA SuperNOVA 450 GM: Best aligned with a connector checklist that includes 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA, and 4 Pin Peripheral.
- SilverStone SST-ST30SF: A sensible route when open-box condition and a one-fan cooling arrangement suit the plan.
- Silver Stone SST-ST45SF: Choose when a used-condition SFX power supply fits the intended purchase.
- Asiahorse 16Awg PSU Cable Extension: Focus here when male-to-male cable extensions are the relevant requirement.
Product notes
SilverStone SST-ST30SF SFX Form Factor 300W 80Plus Bronze Power Supply
The SST-ST30SF makes sense when its stated 24 Pin, 20 Pin, 20+4 Pin, and 8 Pin 12V connector group is central to your component plan. Those connector labels are the clearest reason to choose it over a cable-extension set, since it is itself a power supply. The limiting detail is its open-box condition. The SST-ST30SF is best for someone whose decision turns on those named connectors; it is a less direct fit when a 450W label is the requirement.
Silver Stone SST-ST45SF 450W SFX 80 Plus Bronze Power Supply
The SST-ST45SF puts 450W and 80 Plus Bronze wording together in one named model. That is the concrete reason to select it when those two title details define the search. The caveat is prior use: the description says scratches may show, so cosmetic condition belongs in the decision. Its USD 65 price matches the SST-ST30SF in the table, so the named wattage and cosmetic trade-off carry the decision. Choose the SST-ST45SF when the 450W and Bronze labels define the brief.
EVGA SuperNOVA 450 GM 450W 80 Plus Gold SFX Fully Modular Power Supply
The SuperNOVA 450 GM meets the specific ask for a new-condition, fully modular 450W SFX power supply. Its connector set names 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA, and 4 Pin Peripheral, and the description also identifies ECO Mode with a DBB fan. The compromise is simple and concrete: at USD 70, it occupies the highest listed price. Choose EVGA when the fully modular designation and new condition outrank the $5 difference from the two USD 65 power supplies.
Asiahorse 16Awg Psu Cable Extension Sleeved Custom Mod Gpu Pc Audio Video Power
Asiahorse takes the cable side of the decision: the title identifies a sleeved PSU cable extension, not a power supply. Its connector configuration is male-to-male with 2 X 8 Pin PCIe, 1 X 8 Pin EPS, and 1 X 24 Pin ATX. The description also identifies nylon braid construction and four combs supplied with each cable, details for shoppers who want cables arranged into a defined shape. The limitation is fundamental: Asiahorse extends existing power-supply cables rather than replacing the power supply. Choose it when cable extensions are the goal, not when an SFX wattage designation is needed.
Final recommendations by use case
- Choose the EVGA SuperNOVA 450 GM when ECO Mode with a DBB fan is the listed detail that matters most.
- Choose the SilverStone SST-ST30SF when its named 24 Pin, 20 Pin, 20+4 Pin, and 8 Pin 12V connector group is decisive.
- Choose the Silver Stone SST-ST45SF when an SFX form factor is required and its used condition fits your plan.
- Choose Asiahorse when nylon braid construction and four included combs are the cable-management details you want.
