Choosing pc power supplies & cables starts with one important split: do you need a complete power source, or are you solving a connector and cable-routing task? The ATX 1000W model is the only full power supply in this group. The remaining choices are purpose-specific cables or extensions, so the right pick depends far more on the job in your build than on picking the lowest sticker price.
Quick take
Start with the part of the build that needs attention. A full ATX system build points toward the modular power supply; a graphics-card connector layout, a named Tesla cable need, or a white cable-routing plan points toward one of the three cable-focused entries. The $76.20 gap between the lowest and highest listed prices reflects that divide between an individual cable and a complete PSU.
Listed price comparison
| Choice | Listed price | Price position |
|---|---|---|
| Dual PCIe 8Pin to CPU 8Pin cable | USD 9.90 | |
| ATX 1000W Full Modular Power Supply | USD 86.10 | |
| HUHOU PCIe 8 Pin dual 6+2 extension cable | USD 13.99 | |
| Asiahorse Snow White cable extension kit | USD 19.99 |
The two individual GPU-oriented cable entries sit close together in price, while the Snow White extension kit adds a multi-cable presentation focus. The ATX unit belongs in a different purchase decision because it is a power supply rather than an add-on lead.
Decision matrix
- Need a complete ATX power supply: Choose the ATX 1000W Full Modular Power Supply. It has an ATX form factor, a fully modular design, and 20+4 Pin plus 4+4 CPU connectors.
- Need a short, named Tesla-focused cable: Choose the Dual PCIe 8Pin to CPU 8Pin cable. Its title specifically names NVIDIA Tesla K80, P40, and P100 and includes 12.5CM.
- Need a GPU connector splitter arrangement: Choose the HUHOU extension cable. It is described as an 8 Pin female connection leading to dual 8 Pin 6+2 male connections.
- Need coordinated cable routing in Snow White: Choose the Asiahorse kit. Its four-piece set includes matching cable combs to keep individual wires spaced and organized.
Product notes
Dual PCIe 8Pin to CPU 8Pin Power Cable for NVIDIA TESLA K80 P40 P100
This cable makes sense when a build plan specifically names NVIDIA Tesla K80, P40, or P100 hardware and calls for the Dual PCIe 8Pin to CPU 8Pin arrangement. The 12.5CM wording keeps the purchase centered on a short cable run rather than a broad cable-management project. Its limitation is equally concrete: the title is tightly focused on three Tesla models, unlike the other choices that address general GPU connector branching, a multi-lead extension kit, or a full ATX supply. It is a straightforward new cable choice for a narrowly defined connection need.
ATX 1000W Full Modular Power Supply, 80+ Bronze Dual CPU PC PSU with ARGB Fan
Pick this model when the cart needs a complete ATX power supply rather than an extension cable. Its fully modular layout is intended to support a cleaner, more organized case, while the title also calls out an ARGB fan and 80+ Bronze designation. The connector list includes 20+4 Pin and 4+4 CPU, giving this entry a broader system-build role than the cable-only choices. The trade-off is scope: at the highest listed price, it is aimed at supplying a PC build, not simply changing the routing or connector arrangement of existing power cables.
Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin 6+2 Male Extension Cable
The HUHOU cable is the focused pick for a graphics-card power layout that calls for one 8 Pin PCIe female input and two 6+2 Pin PCIe male outputs. Its black-and-yellow finish gives it a distinct visual direction, and the description identifies a two-pack quantity. A particularly important limitation is stated directly: this is a GPU-to-GPU splitter cable, not a CPU 8-pin cable. That makes the choice easy to narrow-choose it for the named graphics-card connector arrangement, not for a CPU power connection or an all-system cable presentation kit.
Asiahorse 18Awg PSU Cable Extension Sleeved Custom Mod GPU, Video, PC Snow White
Asiahorse takes the broader cable-management route with a four-piece Snow White braided extension kit. The set includes a 24-pin ATX motherboard extension, a 4+4-pin EPS CPU extension, and two 6+2-pin PCI-E GPU extensions, plus matching cable combs. Choose it when consistent white routing and orderly wire spacing matter across several areas of a PC build. Its limitation is the same feature that defines its purpose: this is a cable extension kit. It addresses the visible cable run and organization, while a shopper seeking the main power source should instead look to the separate ATX 1000W power supply.
Final recommendation by use case
For a complete power-source purchase, choose the ATX 1000W Full Modular Power Supply at USD 86.10. For a Snow White cable-routing project, the Asiahorse 18Awg PSU Cable Extension Sleeved Custom Mod kit at USD 19.99 is the more targeted match. Choose the HUHOU PCIe 8 Pin Female to Dual 8 Pin 6+2 Male Extension Cable at USD 13.99 for the stated GPU splitter layout. If your build requirement specifically names Tesla K80, P40, or P100, the Dual PCIe 8Pin to CPU 8Pin Power Cable at USD 9.90 is the narrowest fit.
