Choosing pc power supplies & cables gets confusing when a cart mixes a complete SFX unit with extensions, converters, and splitter leads. The useful first move is not chasing the lowest tag: decide whether you are replacing the power supply, organizing existing wiring, changing a 6-pin GPU connection, or using a one-to-dual GPU cable layout. That decision narrows the choice quickly.
Quick take
The main divide is between a power supply and add-on cabling. The EVGA SuperNOVA 450 GM is a 450W power supply, while Asiahorse is a coordinated extension set. The 6-pin-to-8-pin cable and the HUHOU lead each target more specific GPU connection arrangements. The listed-price spread is $65.04, reflecting these different roles rather than a simple like-for-like ladder. Match the connector job first, then use cable appearance, modular design, and included connection types to settle the choice.

Decision matrix
- Replacing a power supply: Choose the EVGA SuperNOVA 450 GM, which is identified as a fully modular 450W SFX power supply.
- Creating uniform white cable runs: Choose Asiahorse for its Snow White braided extensions and matching cable combs.
- Changing one 6-pin GPU lead to an 8-pin connection: Choose the 6-pin to 8-pin PCI Express Power Converter Cable.
- Using an 8-pin female GPU connection with two 6+2-pin male ends: Choose the HUHOU GPU extension cable for that stated layout.
Product notes
6-pin to 8-pin PCI Express Power Converter Cable GPU Video Card PCIE PCI-E 18AWG
The narrowest and least expensive route here is aimed at a defined connector change: a 6-pin PCI Express lead on one end and an 8-pin PCI Express connection on the other. That makes it a straightforward candidate when that exact GPU-power mismatch is the task. Its listed 18AWG wiring keeps the focus on a functional converter cable rather than a cosmetic extension system. The limitation is its single-purpose layout. It will not provide the motherboard, CPU, and GPU extension assortment included with the Asiahorse kit, and it does not take the place of a standalone power supply.
Asiahorse 18Awg PSU Cable Extension Sleeved Custom Mod GPU, Video, PC Snow White
Asiahorse is for someone who wants routed cables to look coordinated rather than merely changing one GPU connector. The Snow White braided set includes a 24-pin ATX motherboard extension, a 4+4-pin EPS CPU extension, two 6+2-pin PCI-E GPU extensions, and matching cable combs. That combination suits a build where motherboard, CPU, and graphics-card wiring all need the same visual treatment. Its limitation is scope: each piece is an extension, so the kit works alongside an existing standard ATX power supply instead of replacing the EVGA power unit.
Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin (6+2) Male Extension Cable
The HUHOU cable addresses a different connector arrangement from the 6-pin converter: its 8-pin PCI Express female end feeds two 6+2-pin PCI Express male ends. The black and yellow colorway may fit a build where that look is intentional, while the title clearly positions it as a GPU/VGA extension cable. Choose it for that explicit one-to-dual arrangement rather than for broad cable tidying. The limitation is equally practical: a build beginning with a 6-pin PCI Express lead has a different connection requirement, while a coordinated multi-lead presentation is better matched by Asiahorse.
EVGA SuperNOVA 450 GM 450W 80 Plus Gold SFX Fully Modular Power Supply. New
The EVGA SuperNOVA 450 GM is the entry to choose when the shopping list needs an actual 450W power supply instead of an add-on lead. Its fully modular design is paired with 24-pin, 4+4 CPU, 6+2 PCI Express, SATA, and 4-pin peripheral connectors, bringing several internal connection types into one unit. The 80 Plus Gold wording and ECO Mode are also part of its stated configuration. The limitation is its position at the top of the listed-price range. It is a fundamentally different purchase from the three cable-focused choices.
Final recommendation by use case
Choose the EVGA SuperNOVA 450 GM when replacing the power supply itself is the goal. Pick the Asiahorse extension kit for a grouped motherboard, CPU, and GPU extension set with cable combs. Select the 6-pin to 8-pin converter for a one-connector GPU change. The HUHOU extension cable fits the stated GPU fan-out configuration. These are complementary build parts with distinct jobs, not interchangeable alternatives.
