Choosing among pc power supplies & cables starts with one key question: are you replacing the power unit itself, solving a specific graphics-card connection, or cleaning up the visible cable runs in a case? These four choices cover very different jobs, so the lowest listed price is not automatically the right answer. The useful move is to match the connector role and build goal before comparing cost.
Quick take
The ATX Full Modular Power Supply is the complete power-unit choice; the other three are cable-focused. The Tesla-focused cable is a short, narrowly named connection piece, while the HUHOU cable is expressly a GPU-to-GPU dual-output splitter. For a coordinated visible-cable setup, the sleeved extension kit brings black-and-purple sleeving and cable combs. Across the four listed prices, the range spans USD 76.20, reflecting the difference between individual cables, an extension set, and a full ATX unit.
Listed price comparison
| Item | Listed price | Price position |
|---|---|---|
| Tesla-focused 8Pin cable | USD 9.90 | |
| ATX Full Modular Power Supply | USD 86.10 | |
| HUHOU dual 8Pin GPU splitter | USD 13.99 | |
| Sleeved PSU extension kit | USD 39.67 |
Decision matrix
- Replacing the central power unit: The ATX 1000W Full Modular Power Supply is the relevant pick because it is an ATX power supply with modular cabling, rather than an add-on cable.
- Connecting the named Tesla hardware: Choose the Dual PCIe 8Pin to CPU 8Pin cable when K80, P40, or P100 naming and a 12.5CM cable match the intended setup.
- Splitting a spare GPU power connection: The HUHOU Graphics Card GPU VGA cable is the dedicated GPU 8-pin female to dual 6+2-pin male route.
- Making cable runs more uniform: The sleeved extension kit is the fit for extensions, cable combs, and its black-and-purple finish.
Product notes
Dual PCIe 8Pin to CPU 8Pin Power Cable for NVIDIA TESLA K80 P40 P100
At USD 9.90, this is the focused choice for a build that specifically calls for the NVIDIA Tesla K80, P40, or P100 wording in the title and a dual PCIe 8Pin-to-CPU 8Pin connection. Its appeal is directness: it is a cable intended for one narrowly described connection task, not a broad cosmetic kit or a replacement power supply. The 12.5CM designation is also a concrete reason to select it when a short cable run is wanted. That same short listed length is its limitation; shoppers planning a longer route through a case should look toward an extension-oriented option instead.
ATX Full Modular Power Supply
The ATX Full Modular Power Supply is the clear selection when the goal is to add a complete power unit rather than modify existing cable routing. Its listed ATX form factor, full modular design, 20+4-pin connector, and 4+4 CPU connector make it distinct from the three cable accessories here. Modular cabling is especially relevant to shoppers prioritizing a cleaner, more organized case layout. The trade-off is its USD 86.10 listed price, the highest in this comparison. It is therefore aimed at a different purchase than a simple connector cable or an extension kit, not a substitute for either one.
Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin (6+2) Male Extension Cable
Choose the HUHOU GPU cable for the explicitly described GPU 8-pin female to dual 8-pin, 6+2-pin male layout. At USD 13.99, it offers a targeted route for a graphics-card wiring plan that needs a dual-output splitter arrangement. The title and connector description keep the role unusually specific: it is presented as a GPU-to-GPU cable, with one female input and two PCIe outputs. That specificity is also the limitation. It is expressly not a CPU cable, so it is not the right selection for a CPU-power connection even though both categories can use eight-pin terminology.
PSU Cable Extension Kit Sleeved Cable Custom Power Supply Sleeved Extension 16 A
The USD 39.67 sleeved extension kit suits a shopper who wants visible cable runs to look more coordinated while extending factory PSU cables. Black-and-purple sleeving, a 24-pin ATX extension connection, and included cable combs give it a clear cable-management purpose. The kit also lists a 4+4-pin EPS cable plus PCIe extensions, making it the broadest cable-routing assortment of the four. Its important limitation is built into the design: these are extensions that connect to factory PSU cables and do not connect directly to the power supply. It is a finishing and routing choice, not a replacement PSU.
Final recommendation by use case
For a complete ATX power-supply purchase, choose the ATX Full Modular Power Supply. For the named Tesla K80, P40, or P100 connection task and a short cable, the Dual PCIe 8Pin to CPU 8Pin cable is the focused option. Select the HUHOU dual 8Pin cable only for its stated GPU-to-GPU splitter role. If the priority is a black-and-purple cable presentation with extensions and combs, the PSU Cable Extension Kit is the more appropriate match.
