Choosing among pc power supplies & cables starts with one essential question: do you need a complete power supply, or do you need a cable for a particular connection path? The price gap can be substantial, but a low-cost cable cannot replace an ATX or SFX power supply in a build. Separate the component role first, then use form-factor wording, connector layout, and condition to make the practical choice.
Quick take
The ATX Full Modular Power Supply with ARGB Fan and the Silver Stone SST-ST45SF are the complete-power choices here. The Dual PCIe 8Pin to CPU 8Pin Cable and the HUHOU GPU extension cable address narrower cable needs. Start with that divide before looking at price: the USD 76.20 listed-price span covers two very different kinds of PC component.
Listed-price comparison
| Choice | Listed price | Relative listed price |
|---|---|---|
| Dual PCIe 8Pin to CPU 8Pin Cable | USD 9.90 | |
| ATX Full Modular Power Supply with ARGB Fan | USD 86.10 | |
| GPU PCIe 8 Pin to Dual 8 Pin Extension Cable | USD 13.99 | |
| Silver Stone SST-ST45SF SFX Power Supply | USD 65.00 |
The two cables occupy the lower end of the range, while the two standalone power supplies sit at higher listed prices. That difference is useful for budgeting, but it should not be treated as a measure of capability across unlike component types.
Decision matrix
- Need a complete desktop power supply: focus on the ATX Full Modular Power Supply with ARGB Fan or the Silver Stone SST-ST45SF rather than either cable.
- Need an SFX-labeled unit: the Silver Stone SST-ST45SF is the direct match; the other complete PSU is labeled ATX.
- Need a specific cable route: the Dual PCIe cable title names NVIDIA Tesla K80, P40, and P100, while the HUHOU cable is labeled as an 8 Pin female to dual 8 Pin 6+2 male extension.
- Condition is a deciding factor: the Silver Stone unit is listed used, while the ATX power supply and both cables are listed new.
Product notes
Dual PCIe 8Pin to CPU 8Pin Cable for NVIDIA Tesla K80, P40 and P100
This cable earns its place for shoppers whose search is already narrowed by the NVIDIA Tesla K80, P40, or P100 model names in the title. The stated dual PCIe 8Pin-to-CPU 8Pin configuration gives a concrete connector description, and the low listed price keeps it in replacement-cable territory rather than complete-system territory. Its limitation is that narrow focus: it is a cable with a particular labeled connection path, not a standalone power supply. Choose it when the model wording and connector description align with the cable you are trying to source, not when the build requires a new PSU.
ATX Full Modular Power Supply with ARGB Fan
For a standard ATX build where cable organization is a priority, the full modular design is the main reason to choose this unit. Its connector list includes 20+4 Pin and 4+4 CPU, and the description specifically presents modular wiring as a route to a cleaner, more organized case. The ARGB fan is another named design detail. The tradeoff is its USD 86.10 listed price, the highest in this comparison. It makes the most sense when you are buying a complete ATX power supply and want the modular cable-management focus, rather than when the task is simply adding a PCIe extension cable.
Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin 6+2 Male Extension Cable
The HUHOU extension cable is the targeted pick for a GPU-oriented connector path: its title spells out an 8 Pin female input and dual 8 Pin 6+2 male outputs. The description also characterizes it as a graphics-card extension cable, giving the shopper a clear reason to consider it when that is the needed arrangement. At USD 13.99, it remains near the lower end of the four listed prices. Its limitation is component scope. This is an extension and splitter-style cable, not a complete power supply, so it belongs in a cable-specific purchase rather than a PSU replacement decision.
Silver Stone SST-ST45SF 450W SFX 80 Plus Bronze Power Supply
The Silver Stone SST-ST45SF is the straightforward choice for a shopper seeking an SFX-labeled power supply. Its title identifies the 450W rating and 80 Plus Bronze designation, making it distinctly positioned from the ATX unit and the cable listings. Its USD 65.00 listed price also places it below the ATX Full Modular Power Supply with ARGB Fan. The key limitation is condition: this unit is listed used, and the description notes scratches from prior use. Pick the Silver Stone when the SFX form-factor label is central to your build plan and a used power supply fits that preference.
Final recommendation by use case
Choose the ATX Full Modular Power Supply with ARGB Fan for a complete ATX build centered on modular cable management. Choose the Silver Stone SST-ST45SF when an SFX power supply is the required format and a used unit suits the purchase. Choose the Dual PCIe 8Pin to CPU 8Pin Cable when the Tesla K80, P40, or P100 wording matches your cable search. Choose the HUHOU GPU extension cable when you specifically need its female-to-dual 8 Pin 6+2 layout for a graphics-card cable path.
