Choosing pc power supplies & cables starts with one important split: do you need a complete desktop power unit, or a cable that changes or branches a PCIe connection? The ATX 1000W Full Modular Power Supply is the only full PSU here. The other choices are purpose-specific cables, each with a different connector arrangement in its name. Separating those jobs first keeps a compact cable purchase from being mistaken for the central component of a desktop build.
Quick take
- Pick the ATX 1000W Full Modular Power Supply, 80+ Bronze Dual CPU PC PUS with ARGB Fan when the goal is a full power unit with modular cable management.
- The Dual PCIe 8Pin to CPU 8Pin Power Cable for NVIDIA TESLA K80 P40 P100 is the cable with a 12.5CM designation in its title.
- The Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin (6+2) Male Extension Cable stands apart with its black-and-yellow color scheme.
- For the lowest listed upfront price, the 6-pin to 8-pin PCI Express Power Converter Cable is the USD 4.96 choice.
Listed price comparison
| Item | Listed price | Price position |
|---|---|---|
| Dual PCIe 8Pin to CPU 8Pin Power Cable | USD 9.90 | |
| ATX 1000W Full Modular Power Supply | USD 86.10 | |
| GPU 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 | USD 4.96 |
The listed range spans USD 81.14 from the 6-pin-to-8-pin converter to the full modular ATX unit. That wide spread reflects two different purchase types: a complete power supply versus individual cable solutions.
Decision matrix
Choose the ATX 1000W Full Modular Power Supply for a desktop power-unit route. Its ATX form factor and stated 20+4 Pin plus 4+4 CPU connectors make it the relevant choice when the build needs the main PSU rather than a PCIe adapter.
Choose the Dual PCIe 8Pin to CPU 8Pin Power Cable for the specifically named NVIDIA Tesla K80, P40, and P100 use case. The title is notably focused, which is useful when those model names are central to the shopping decision.
Choose the GPU 8 Pin Female to Dual 8 Pin (6+2) Male Extension Cable when a two-cable package is useful. Its package quantity is two, unlike the single cable presentation of the other cable entries.
Choose the 6-pin to 8-pin PCI Express Power Converter Cable when the listed 18AWG converter format is the item sought. Its named input and output arrangement is different from the dual-output layout of the HUHOU cable.
Product notes
Dual PCIe 8Pin to CPU 8Pin Power Cable for NVIDIA TESLA K80 P40 P100
This is the clearest choice for shoppers seeking a cable explicitly named for NVIDIA Tesla K80, P40, and P100 hardware. The dual PCIe 8Pin-to-CPU 8Pin wording identifies the stated endpoint arrangement, and the title also specifies a 12.5CM length. Its limitation is that narrow focus: the naming is tied to a particular Tesla trio instead of being presented as a broadly labeled graphics-card extension. It fits a targeted cable search better than a general-purpose shopping list, especially when the named hardware is the reason for the purchase.
ATX 1000W Full Modular Power Supply, 80+ Bronze Dual CPU PC PUS with ARGB Fan
Choose this full PSU when an ARGB fan is part of the desired component list. The black finish and one-fan cooling configuration provide the other stated visual and cooling details, while the 20+4 Pin and 4+4 CPU connectors identify its desktop-oriented connector set. The main limitation is its USD 86.10 listed price, the highest figure in this comparison. That places it in a different buying decision from the cable entries: it is for shoppers selecting the core power-supply component rather than solving one PCIe cable connection.
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 an 8 Pin PCI Express female connection that branches to dual 8 Pin (6+2) male ends. It is supplied as a two-cable package and uses a black-and-yellow color combination, useful for shoppers who want that stated appearance rather than an all-black presentation. The limitation is equally specific: its input side is 8 Pin PCI Express, not the 6 Pin PCI Express input named on the converter cable below. Choose it for the dual-output configuration, not for a direct six-pin-to-eight-pin conversion.
6-pin to 8-pin PCI Express Power Converter Cable GPU Video Card PCIE PCI-E 18AWG
This converter is the direct match when the task is connecting a 6-pin PCIe power cable to an 8-pin PCIe video-card connection. Its 18AWG designation appears in the product name, giving shoppers a clearly labeled cable format for that connector change. The trade-off is its fixed conversion role: the cable goes from 6 Pin PCI Express to 8 Pin PCI Express rather than splitting one 8-pin female connection into two 6+2 outputs. It is therefore the more targeted choice for that named conversion, not the branching job handled by the HUHOU lead.
Final recommendation by use case
- Complete desktop PSU with an ARGB fan: choose the ATX 1000W Full Modular Power Supply.
- Tesla K80, P40, or P100-focused cable search at USD 9.90: choose the Dual PCIe 8Pin to CPU 8Pin Power Cable.
- One 8-pin female connection branching to dual 6+2 male ends: choose the HUHOU GPU extension cable.
- A 6-pin PCIe-to-8-pin PCIe conversion: choose the USD 4.96 converter cable.
