Choosing among pc power supplies & cables starts with one important split: do you need to replace the power supply itself, or do you want to change the look and routing of cables already connected to a power supply? The three SilverStone and EVGA entries are SFX power supplies, while the Asiahorse option is a four-piece extension kit. That makes the lowest-priced entry a different kind of purchase rather than a direct replacement for a PSU.
Quick take
The EVGA SuperNOVA 450 GM is the new, fully modular choice, with a broad named connector selection. SilverStone offers two differently configured SFX units at the same listed price: the SST-ST30SF is the 300W open-box entry with a detailed connector list, while the SST-ST45SF is a used 450W model. Asiahorse is for cable presentation, bringing Snow White braided extensions and matching combs to a standard ATX power supply setup.
The listed-price range runs from USD 19.99 to USD 70.00, a USD 50.01 gap. Treat that range as a reflection of the two purchase types here: extension cables on one side and power supplies on the other.
Listed price comparison

Decision matrix
- Need SATA, PCI Express, CPU, and peripheral connector types named together: choose the EVGA SuperNOVA 450 GM.
- Shopping specifically for a 300W configuration: the SilverStone SST-ST30SF is the relevant match.
- Want the alternate Silver Stone configuration at the shared listed-price point: look to the SST-ST45SF.
- Refreshing cable appearance with Snow White braiding and cable combs: select the Asiahorse extension kit.
Product notes
SilverStone SST-ST30SF
The SilverStone SST-ST30SF suits a build plan that calls for a 300W power supply with 20-pin, 20+4-pin, 24-pin, and 8-pin 12V connectors named together. A single-fan cooling setup and black color are also specified. It is identified as SFX form factor, keeping that requirement explicit rather than leaving it to inference. Choose it when this connector mix is the deciding detail. Its main limitation is the open-box condition. It is a power supply rather than a cable-extension kit, so it belongs in a replacement or component-build decision rather than a cable-routing-only purchase.
Silver Stone SST-ST45SF
The Silver Stone SST-ST45SF is a direct choice for shoppers who want the 450W name in an SFX power supply and are comfortable selecting a used component. Its title keeps the configuration straightforward: a 450W, 80 Plus Bronze power supply. The model's 80 Plus Bronze designation is shared with the SST-ST30SF, so it should not be treated as a deciding advantage between those two. The concrete trade-off is condition: it is used, and cosmetic scratches from prior use are stated. Select this route when the named 450W configuration matters more than new condition.
EVGA SuperNOVA 450 GM
The EVGA SuperNOVA 450 GM fits a purchase brief where a fully modular design is important. Its connector inventory includes 24-pin, 4+4 CPU, 6+2-pin PCI Express, SATA, and 4-pin peripheral connections, giving a specific set of cable types to plan around. It is listed in new condition and uses the SFX form factor. Choose it for the combination of new condition and modular configuration rather than as a cable-extension solution. Its limitation is the USD 70.00 listed price, which is the highest in this group. That makes it the clearest fit for a defined configuration, not the lowest-ticket route.
Asiahorse 18AWG Cable Extension Kit
Asiahorse's kit speaks to cable presentation rather than supply replacement. The four included extensions cover one 24-pin ATX motherboard lead, one 4+4-pin EPS CPU lead, and two 6+2-pin PCI-E GPU leads; matching cable combs are included. Its 18AWG wiring is paired with soft, flexible nylon braiding intended to hold routing shape. Choose it when you already have a standard ATX power supply and want this extension layout for motherboard, CPU, and graphics-card connections. The limitation is role: it is a cable-extension kit, separate from the power-supply units compared above.
Final recommendation by use case
For a build needing a new, fully modular SFX unit, choose the EVGA SuperNOVA 450 GM. Pick the SST-ST30SF when its named multi-pin connector mix and open-box condition fit the plan. The SST-ST45SF is the appropriate route for a used 450W SFX configuration with an 80 Plus Bronze designation. For cable routing rather than PSU replacement, choose Asiahorse for its four included extension leads and matching combs.
