Choosing pc power supplies & cables comes down to one early fork in the road: are you powering the whole build, fitting a compact SFX layout, working with an ATX case, or adding a graphics-card power connection? These four picks cover very different jobs. The most useful way to narrow them is to separate complete power supplies from the dedicated PCIe extension cable before weighing form factor, condition, and the connections named for each.
Quick take
The listed-price spread is $56.01, but the lowest-priced entry is a GPU extension cable rather than a complete power supply. For a full system PSU, the choices divide into Enermax's high-output MaxRevo, EVGA's SFX fully modular SuperNOVA 450 GM, and Segotep's open-box ATX 650W unit. The HUHOU cable belongs on a different shortlist: it is for a stated graphics-card power-line connection.
Listed price comparison
| Pick | Listed price | Price position |
|---|---|---|
| Enermax MaxRevo 1350W | USD 64.89 | |
| EVGA SuperNOVA 450 GM | USD 70.00 | |
| Segotep 650W ATX | USD 52.99 | |
| HUHOU PCIe extension cable | USD 13.99 |
Decision matrix
- For a build described around multi-GPU rigs or extreme-performance systems: the Enermax MaxRevo 1350W is the relevant full-size ATX / EPS12V choice.
- For an SFX-form-factor build that calls for fully modular cables: the EVGA SuperNOVA 450 GM is the focused match.
- For an ATX setup where a non-modular 650W supply fits the brief: the Segotep GN-650 is the direct option.
- For a graphics-card power-line extension with an 8-pin female input and dual 6+2-pin PCIe male outputs: choose the HUHOU cable rather than replacing the PSU.
Product notes
Enermax MaxRevo 1350W Modular PC Power Supply 80 PLUS Gold EMR1350EWT w/ Cables

The MaxRevo is worth prioritizing when the build plan specifically mentions multi-GPU rigs or extreme-performance systems. Its description identifies six independent +12V rails with up to 112A combined output, giving this model a clearly stated high-output configuration. The EMR1350EWT model number in the title also makes the selection easy to identify alongside a parts list. The key limitation is condition: this Enermax unit is marked used. Its steel / metal enclosure, 50-60 Hz frequency range, and 115-240 VAC listing add context, but the used designation should be central to the purchase decision.
EVGA SuperNOVA 450 GM 450W 80 Plus Gold SFX Fully Modular Power Supply

EVGA's SuperNOVA 450 GM is the cleanest fit for a compact SFX build that benefits from a fully modular supply. It is marked new and names a broad connector set: 24-pin, 4+4 CPU, 6+2-pin PCI Express, SATA, and 4-pin peripheral. ECO Mode with a DBB fan is another named feature for shoppers comparing the details around cooling behavior. The limitation is the listed 450W output, which is a different capacity figure from the 650W and 1350W supplies here. Choose this EVGA when SFX format is the deciding build requirement, not simply because it carries the highest listed price.
OPEN BOX 650W Power Supply 80 Plus Gold Non-Modular ATX Gaming PC Case PSU

The Segotep GN-650 makes sense for a parts list calling for an ATX supply with a 20+4-pin connector. Beyond its stated 650W figure, it names a 120mm fan, PFC protection, and 80 Plus Gold efficiency. Those specifics make it a more defined full-system choice than the PCIe extension cable, while its black finish keeps the presentation straightforward. There are two practical constraints in the title and description: it is open box and non-modular. That combination suits a shopper comfortable with the stated condition and a fixed-cable design, rather than someone whose priority is a fully modular layout.
Graphics Card GPU VGA PCIe 8 Pin Female to Dual 8 Pin (6+2) Male Extension Cable

HUHOU's cable serves a narrower but useful role: extending a graphics-card power line when the described GPU connection is needed. The black-and-yellow cable uses an 8-pin PCI Express female connector on one end and dual 6+2-pin PCI Express male connectors on the other. Its stated purpose is to address an insufficient graphics-card power-line connection, making it relevant for that specific wiring task. The limitation is important and explicit: it is a GPU-to-GPU splitter cable, not a CPU 8-pin cable and not a complete power supply. Buy it for the named PCIe extension job, not as a substitute for system power.
Final recommendation by use case
Pick the Enermax MaxRevo 1350W for a build framed around multi-GPU or extreme-performance use and when a used unit is acceptable. Choose the EVGA SuperNOVA 450 GM when the SFX form factor and fully modular design lead the decision. The Segotep 650W ATX fits an ATX build brief where an open-box, non-modular supply is suitable. Select the HUHOU PCIe extension cable only when the goal is the stated graphics-card power-line split, rather than powering an entire PC.
