Choosing pc power supplies & cables comes down to one essential question: are you powering a whole computer, or solving one specific connector arrangement? A 1050W power supply unit is a very different purchase from a short PCIe cable, and the three cable choices here also serve distinct jobs. Start with the connector ends or named hardware in your build, then use price as a secondary filter.
Quick take
The GAMEMAX unit is the clear route when the shopping list calls for a complete PSU. For a connector-focused job, the 6-pin to 8-pin converter is aimed at a direct change from one PCIe end to another, while the HUHOU cable branches an 8-pin PCIe female connection into two 6+2-pin male ends. The Dual PCIe 8Pin to CPU 8Pin cable is the most specifically framed choice, naming NVIDIA Tesla K80, P40, and P100.
The listed range runs from USD 4.96 to USD 119.99, an absolute spread of USD 115.03. That gap reflects the difference between cable accessories and a full power supply, so it should not be treated as a like-for-like comparison.
Listed price comparison
| Item | Listed price | Price scale |
|---|---|---|
| Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin (6+2) Male Extension Cable | USD 13.99 | |
| 6-pin to 8-pin PCI Express Power Converter Cable GPU Video Card PCIE PCI-E 18AWG | USD 4.96 | |
| Dual PCIe 8Pin to CPU 8Pin Power Cable for NVIDIA TESLA K80 P40 P100 | USD 9.90 | |
| GAMEMAX 1050W ATX 3.0 PCIE 5.0 ARGB Smart 80+ Gold Power Supply UNIT (PSU) WHITE | USD 119.99 |
Decision matrix
- Need a full system power supply: Choose the GAMEMAX 1050W ATX 3.0 PCIE 5.0 unit rather than any of the cable-only choices.
- Starting with a 6-pin PCIe connection and targeting 8-pin: The 6-pin to 8-pin PCI Express Power Converter Cable is the direct match.
- Need one 8-pin PCIe female end to feed dual 6+2-pin male ends: The HUHOU extension cable is purpose-built around that layout.
- Working from the named Tesla K80, P40, or P100 context: The Dual PCIe 8Pin to CPU 8Pin cable is the most targeted listing.
Product notes
Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin (6+2) Male Extension Cable
The HUHOU cable fits a build where an 8-pin PCIe female connection needs to branch to two 6+2-pin PCIe male ends. That female-to-dual-male arrangement is the concrete reason to choose it over a simple end-to-end converter: it is framed as a GPU power splitter and extension cable. Its black-and-yellow finish is also clearly specified for shoppers coordinating visible cable colors. The limitation is inherent in the connector layout. Because the input is an 8-pin PCIe female end, it is not the direct answer for a setup beginning with the 6-pin PCIe connection described by the converter cable.
6-pin to 8-pin PCI Express Power Converter Cable GPU Video Card PCIE PCI-E 18AWG
Pick this converter cable when the job is specifically to connect a 6-pin PCIe power cable to an 8-pin PCIe connection for a video card. The connector labels make its purpose unusually straightforward, and the description identifies 18AWG wiring. It is also the lowest-listed-price cable in this group, which suits a narrowly defined connector task rather than a broader power-system purchase. Its constraint is just as specific: this is a single 6-pin-to-8-pin conversion, not the dual 6+2-pin output arrangement named on the HUHOU splitter cable.
Dual PCIe 8Pin to CPU 8Pin Power Cable for NVIDIA TESLA K80 P40 P100
This cable makes the most sense when the named NVIDIA Tesla K80, P40, or P100 hardware is central to the decision. Its title calls out a dual PCIe 8Pin to CPU 8Pin arrangement, giving it a more focused identity than the general graphics-card converter. The 12.5CM designation further distinguishes it as a compact cable item rather than a full power supply unit. The tradeoff is its model-specific framing: shoppers looking only to change a 6-pin PCIe end into an 8-pin end should choose the explicitly named converter instead.
GAMEMAX 1050W ATX 3.0 PCIE 5.0 ARGB Smart 80+ Gold Power Supply UNIT (PSU) WHITE
The GAMEMAX is for shoppers selecting a complete power supply unit, not merely adapting an existing cable. Its title specifies 1050W, ATX 3.0, PCIe 5.0, ARGB, 80+ Gold, and a white finish, giving it a clearly different role from the three cable accessories. The description also positions it for gaming and office use. Its limitation is scope: a full PSU does not directly solve a one-connector task such as a 6-pin-to-8-pin conversion or an 8-pin PCIe split. Choose it when the power supply itself is the item being replaced or added.
Final recommendation by use case
For a direct graphics-card connector conversion, choose the 6-pin to 8-pin PCI Express Power Converter Cable. For an 8-pin PCIe female connection that needs dual 6+2-pin male outputs, the HUHOU extension cable is the relevant layout. Select the Dual PCIe 8Pin to CPU 8Pin cable when the Tesla K80, P40, or P100 naming matches your hardware context. If the real need is a complete system PSU with a stated 1050W rating, choose the GAMEMAX 1050W ATX 3.0 PCIE 5.0 unit.
