Buying pc power supplies & cables gets confusing when a low-cost graphics-card lead appears beside compact power units. The first decision is not which item costs less: it is whether you need to replace the power supply itself or extend a GPU power connection. Once that is clear, the choices become much easier to separate.
Quick take
Three entries here are standalone SFX power supplies, while the HUHOU entry is a graphics-card extension cable. The cable addresses a GPU lead; the power supplies serve a different role in a build. Among the power supplies, narrow the choice using the named output designation, condition, connector list, and modular design rather than treating the options as interchangeable.
Listed price comparison
| Item | Listed price | Relative price | Item type |
|---|---|---|---|
| SilverStone SST-ST30SF | USD 65.00 | Power supply | |
| Silver Stone SST-ST45SF | USD 65.00 | Power supply | |
| EVGA SuperNOVA 450 GM | USD 70.00 | Power supply | |
| Graphics Card GPU VGA PCIe Extension Cable | USD 13.99 | GPU extension cable |
Decision matrix
- Choose the SilverStone SST-ST30SF when its 20 Pin, 20+4 Pin, 24 Pin, and 8 Pin 12V connector list is the deciding detail.
- Choose the Silver Stone SST-ST45SF when the 450W SFX 80 Plus Bronze wording is the configuration you are seeking.
- Choose the EVGA SuperNOVA 450 GM when a fully modular design is the priority.
- Choose the Graphics Card GPU VGA PCIe Extension Cable when an 8 Pin female-to-dual-6+2 male GPU extension arrangement is specifically needed.
Product notes
SilverStone SST-ST30SF SFX Form Factor 300W 80Plus Bronze Power Supply
The SST-ST30SF is aimed at a build that calls for the listed 20 Pin, 20+4 Pin, 24 Pin, and 8 Pin 12V connections. That connector set is the concrete reason to choose the SilverStone unit instead of a graphics-card cable. Its 300W designation keeps the selection specific rather than interchangeable with other power-supply entries. The limitation is condition: the unit is marked open box. A one-fan cooling arrangement is also named, giving shoppers another clear detail for separating it from the other power units.
Silver Stone SST-ST45SF 450W SFX 80 Plus Bronze Power Supply
The Silver Stone SST-ST45SF makes sense when the title phrase 450W SFX 80 Plus Bronze is the exact configuration you are narrowing toward. That direct naming is the reason to put it ahead of a cable-only solution. The limitation is its used condition, and prior-use scratches are described. This route is about choosing that stated power-supply configuration, not about adding reach to a graphics-card connection. Keep it in the power-supply comparison rather than treating it as an alternative to the GPU splitter cable.
EVGA SuperNOVA 450 GM 450W 80 Plus Gold SFX Fully Modular Power Supply. New
The EVGA SuperNOVA 450 GM is the pick when fully modular design is the deciding feature. Its connector list includes 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA, and 4 Pin Peripheral, giving a concrete reason to choose it when those named connection types are part of the shopping criteria. It is also marked new. Its limitation is simply role: the SuperNOVA is a standalone SFX power supply, not a GPU extension lead. A cable-reach problem calls for the separate extension cable instead.
Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin (6+2) Male Extension Cable
The Graphics Card GPU VGA PCIe extension cable is for a narrower job: taking an 8 Pin PCI Express female input to dual 6+2 Pin PCI Express male ends. Choose it when that graphics-card connection pattern, rather than an entire power supply, is the need. It is marked new and carries a black-and-yellow color description. Its key limitation is explicit: it is a GPU-to-GPU splitter cable, not a CPU cable. That makes it a specialized cable choice rather than a substitute for one of the standalone power supplies.
Final recommendation by use case
- For a one-fan cooling listing, choose the SilverStone SST-ST30SF.
- For a used power supply with prior-use scratches described, choose the Silver Stone SST-ST45SF.
- For a connector list that includes SATA and 4 Pin Peripheral, choose the EVGA SuperNOVA 450 GM.
- For a cable-only graphics-card extension need at the listed USD 13.99 price, choose the Graphics Card GPU VGA PCIe Extension Cable.
