Choosing among pc power supplies & cables starts with a simple but important split: are you powering a whole computer, working around an SFX form factor, extending GPU power connections, or looking for the Tesla-named cable arrangement? These four picks are not interchangeable. Two are complete power supplies, while two are cables with much narrower roles. Start with the job in front of you, then let the listed price and condition help settle the decision.
Quick take
The ATX 1000W Full Modular Power Supply is the full-system route for shoppers focused on modular cable management. SilverStone SST-ST30SF is the form-factor-specific choice, with SFX and 300W in its name. The HUHOU cable is aimed at a GPU PCIe split, while the Dual PCIe 8Pin to CPU 8Pin cable is the lowest-priced, Tesla-named cable option. Keep the cable choices in the cable branch of your search rather than comparing them directly with complete PSUs.
Listed price comparison
| Choice | Listed price | Relative listed-price bar |
|---|---|---|
| Dual PCIe 8Pin to CPU 8Pin Cable | USD 9.90 | |
| ATX 1000W Full Modular Power Supply | USD 86.10 | |
| GPU PCIe Dual 8 Pin Extension Cable | USD 13.99 | |
| SilverStone SST-ST30SF SFX Power Supply | USD 65.00 |
The listed range runs from USD 9.90 to USD 86.10, reflecting the difference between individual cable pieces and full power-supply units rather than a like-for-like choice.
Decision matrix
- A complete ATX-oriented power supply with modular cable management: ATX 1000W Full Modular Power Supply.
- An SFX-form-factor power supply path: SilverStone SST-ST30SF SFX Power Supply.
- A GPU PCIe input branching to two 6+2-pin outputs: GPU PCIe Dual 8 Pin Extension Cable.
- A short cable whose name calls out NVIDIA TESLA K80, P40, and P100: Dual PCIe 8Pin to CPU 8Pin Cable.
Product notes
Dual PCIe 8Pin to CPU 8Pin Power Cable
At USD 9.90, this cable is the lowest-priced entry in the comparison, making it the natural starting point when the purchase is limited to a single power-cable task. Choose it when the title's Dual PCIe 8Pin to CPU 8Pin wording and the NVIDIA TESLA K80, P40, and P100 names closely match the arrangement you are shopping for. Its limitation is equally clear: the listed 12.5CM cable format is a narrowly focused cable choice, not the full-power-supply route represented elsewhere here. That distinction keeps a low listed price from distracting from the actual role required.
ATX 1000W Full Modular Power Supply
The USD 86.10 ATX 1000W Full Modular Power Supply suits a shopper selecting a complete PSU and prioritizing cable organization. Its full modular design is explicitly paired with easy cable management, and the title includes both 1000W and dual CPU language. The ARGB fan adds another named element for a build where that feature matters. The limitation is form-factor specificity: this is listed as ATX, while the SilverStone alternative is expressly SFX. It is also the highest-priced choice in this set, so it makes most sense when its whole-unit, modular role is the one you need.
Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin (6+2) Male Extension Cable
For USD 13.99, the HUHOU cable is the focused option for a graphics-card power-routing task described as an 8-pin female connection leading to dual 8-pin, 6+2 male ends. The description also identifies a two-pack, which may suit a shopping list that calls for more than one cable. Pick it for the GPU-to-dual-PCIe role stated in its name rather than for a full system power supply. Its key limitation is explicit: it is identified as a GPU-to-GPU splitter cable and not a CPU 8-pin cable. That clear designation separates it from the Tesla-named cable above.
SilverStone SST-ST30SF SFX Form Factor 300W 80Plus Bronze Power Supply
At USD 65.00, the SilverStone SST-ST30SF is the dedicated choice when SFX form factor is the central requirement. Its 300W maximum power listing and named connectors, including 20+4 Pin and 8 Pin 12V, make it a complete power-supply option rather than a cable accessory. One-fan cooling is also listed. The main limitation is condition: this entry is labeled open box, whereas the other three choices are listed as new. That does not change the SFX focus, but it is a meaningful distinction for a shopper who wants condition to be part of the final choice.
Final recommendation by use case
For a full ATX build centered on modular cable management, choose the T.F.SKYWINDINTL power supply. For the SFX form-factor route, choose the SilverStone SST-ST30SF. Pick the HUHOU extension cable when the desired connection is a GPU 8-pin female to dual PCIe 6+2-pin male arrangement. Choose the Dual PCIe 8Pin to CPU 8Pin cable when the Tesla K80, P40, or P100 wording and short 12.5CM format are the deciding details. The cleanest purchase is the one that matches the role first and price second.
