Building or updating a PC can turn into a connector puzzle quickly: do you need to extend a graphics-card lead, convert one PCIe connector to another, address a specific Tesla card setup, or replace the power supply itself? These pc power supplies & cables serve four distinctly different jobs. The right choice starts with matching the item's stated connector path-or deciding that a complete modular power supply is the real need.
Quick take
The three cable options are not interchangeable with the Enermax MaxRevo unit: they address individual power-cable routes, while the Enermax is a 1350W ATX / EPS12V power supply. Among the cables, the HUHOU model is presented as a GPU splitter/extension, the 6-pin-to-8-pin cable is a direct converter, and the Dual PCIe 8Pin to CPU 8Pin cable is named for NVIDIA Tesla K80, P40, and P100 hardware. Start with the connector task rather than treating the lowest listed price as the automatic answer.
Listed price comparison
| Item | Listed price | Price position |
|---|---|---|
| HUHOU GPU extension cable | USD 13.99 | |
| 6-pin to 8-pin PCIe converter cable | USD 4.96 | |
| Tesla PCIe-to-CPU cable | USD 9.90 | |
| Enermax MaxRevo 1350W | USD 64.89 |
Decision matrix
- Need to branch a graphics-card power connection: The HUHOU cable is the relevant route because it is described as an 8-pin GPU female connection leading to dual 8-pin (6+2) PCIe male ends.
- Need one 6-pin PCIe lead to reach an 8-pin PCIe connection: Choose the 6-pin to 8-pin PCI Express Power Converter Cable. Its named input and output are the clearest match for that specific transition.
- Working with the NVIDIA Tesla models named in the title: The Dual PCIe 8Pin to CPU 8Pin Power Cable is the focused pick, with Tesla K80, P40, and P100 explicitly called out.
- Replacing the power supply rather than adding an adapter: The Enermax MaxRevo is the only complete ATX / EPS12V power supply here, with modular cable connectivity and a 1350W rating.
Product notes
Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin (6+2) Male Extension Cable
This HUHOU cable makes sense for a graphics-card cable layout that starts from an 8-pin PCI Express source and calls for two 6+2-pin PCI Express male ends. That defined split path is the practical reason to select it over a simple converter. The black-and-yellow cable is marked new, and the listing identifies it as an extension/splitter arrangement for GPU power. Its limitation is equally important: the starting connector is 8-pin PCIe female, so it is not the direct 6-pin-input conversion described by the lower-priced 6-pin-to-8-pin cable. Choose it for the stated dual-output GPU routing, not as a general substitute for every PC power connector.
6-pin to 8-pin PCI Express Power Converter Cable GPU Video Card PCIE PCI-E 18AWG
For a build whose existing lead is 6-pin PCIe and whose target connection is 8-pin PCIe, this converter is the most direct match. The title also identifies 18AWG wiring, while the connector labels keep the purpose straightforward: one 6-pin PCI Express end and one 8-pin PCI Express end. At USD 4.96, it occupies the lowest listed-price position in this comparison. The trade-off is its narrow, one-to-one conversion role. It does not supply the HUHOU cable's dual 6+2-pin output arrangement, and it is not presented as a full replacement power supply. Select it when the 6-pin-to-8-pin path is the exact task at hand.
Dual PCIe 8Pin to CPU 8Pin Power Cable for NVIDIA TESLA K80 P40 P100 (12.5CM
The key reason to choose this cable is the unusually specific hardware wording in its title: NVIDIA Tesla K80, P40, and P100 are named directly. It is also identified as a cable rather than a power supply, keeping its role centered on a defined connection rather than a broader system rebuild. The stated route is dual PCIe 8Pin to CPU 8Pin, which separates it from the 6-pin-to-8-pin converter and the GPU splitter/extension. Its limitation is that the description is centered on that Tesla-oriented cable purpose, rather than a broadly labeled graphics-card adapter. At USD 9.90, it sits between the direct converter and HUHOU extension in listed price.
Enermax MaxRevo 1350W Modular PC Power Supply 80 PLUS Gold EMR1350EWT w/ Cables
The Enermax MaxRevo is the selection for shoppers who need a complete power supply, not an additional cable. Its 1350W rating, modular cable design, 80 PLUS Gold designation, and ATX / EPS12V type make it the fundamentally different choice in this group. Modular connectivity can suit a build where only the required cables are connected inside the case. The most important limitation is condition: this MaxRevo is marked used, while the three cable entries are marked new. It also carries the highest listed price at USD 64.89, reflecting its role as a full power-supply unit rather than a single connector solution.
Final recommendation by use case
Choose the 6-pin to 8-pin PCI Express Power Converter Cable for the direct 6-pin-to-8-pin job at USD 4.96. Pick the HUHOU GPU extension cable when a dual 6+2-pin graphics-card cable route is needed, at USD 13.99. The Dual PCIe 8Pin to CPU 8Pin Power Cable is the targeted USD 9.90 choice for the Tesla models named in its title. For a full PSU replacement, the Enermax MaxRevo 1350W is the fit-but factor in its USD 64.89 listed price and used condition.
