PC Power Supplies & Cables: Choose a Modular PSU, SFX Unit, or White Extension Kit

Choose between a high-wattage modular ATX supply, a compact SFX modular unit, a non-modular ATX supply, or a four-piece white cable extension kit by matching the listed format, condition, connectors, and price to your build plan.

Last updated Aug 24, 2026

Building or refreshing a PC often comes down to one practical choice: do you need the power supply itself, a compact form factor, simpler fixed cabling, or a cleaner-looking cable run? These pc power supplies & cables cover four distinctly different routes. The Enermax is the listed high-wattage modular ATX choice, EVGA is the SFX modular option, Segotep is the open-box non-modular ATX unit, and Asiahorse focuses on Snow White cable extensions rather than supplying power.

Quick take

Start with the role each item plays in your build. Pick the Enermax MaxRevo 1350W when a used ATX / EPS12V power supply with fully modular connectivity and cables is the target. Choose the EVGA SuperNOVA 450 GM when an SFX form factor and a new, fully modular unit matter most. The Segotep 650W suits a build plan centered on an ATX supply with a fixed-cable, non-modular layout. The Asiahorse 18AWG kit is for presentation and routing: it includes motherboard, CPU, and PCI-E extensions in Snow White sleeving.

The listed prices run from $19.99 to $70.00, a $50.01 spread. That range reflects the fact that one listing is a cable extension kit while the other three are power supplies.

Decision matrix

  • Need a listed 1350W ATX / EPS12V supply with modular cables: Enermax MaxRevo 1350W is the direct match.
  • Planning around an SFX power-supply form factor: EVGA SuperNOVA 450 GM is the only SFX entry here.
  • Want an ATX unit listed as open box with a non-modular cable design: Segotep 650W fits that specific combination.
  • Adding white routing extensions to an existing standard ATX power supply: Asiahorse provides a 24-pin ATX extension, a 4+4-pin EPS extension, two 6+2-pin PCI-E extensions, and cable combs.
  • Condition matters to your decision: EVGA and Asiahorse are listed new; Enermax is used, while Segotep is open box.

Product notes

Enermax MaxRevo 1350W Modular PC Power Supply 80 PLUS Gold EMR1350EWT w/ Cables

Enermax MaxRevo 1350W Modular PC Power Supply 80 PLUS Gold EMR1350EWT w/ Cables

The Enermax MaxRevo is the sensible pick for a build specifically calling for a 1350W ATX / EPS12V power supply and modular cable connectivity. Its title and description identify the EMR1350EWT model, 80 PLUS Gold certification, included cables, and a fully modular layout, which gives this option a clear role among the three power supplies. It is also listed with six independent +12V rails and 112A combined output, details that may matter to shoppers comparing named electrical configurations. The important trade-off is condition: this Enermax is listed as used. It also carries a $64.89 listed price, placing it close to the highest-priced entry without being the compact SFX choice.

EVGA SuperNOVA 450 GM 450W 80 Plus Gold SFX Fully Modular Power Supply

EVGA SuperNOVA 450 GM 450W 80 Plus Gold SFX Fully Modular Power Supply. New

Choose the EVGA SuperNOVA 450 GM when your shopping priority is an SFX-form-factor power supply with fully modular cabling. It is listed new and includes 24-pin, 4+4 CPU, 6+2-pin PCI Express, SATA, and 4-pin peripheral connectors, making the connector list especially useful for a build plan that calls for those plug types. The description also names ECO Mode with a DBB fan. This is the entry to select for the SFX requirement itself, not merely for a different wattage figure. Its limitation is the $70.00 listed price, the highest in this comparison, and the 450W model designation may not match a shopper seeking the Enermax's named 1350W configuration.

OPEN BOX 650W Power Supply 80 Plus Gold Non-Modular ATX Gaming PC Case PSU

OPEN BOX 650W Power Supply 80 Plus Gold Non-Modular ATX Gaming PC Case PSU

The Segotep 650W is a straightforward route for someone seeking an ATX power supply labeled 80 Plus Gold with a non-modular design. It is listed open box and includes a 20+4-pin connector, a 120mm fan, and one fan in the attributes. At $52.99, it sits between the cable kit and the two modular power supplies. The fixed-cable arrangement is the key distinction: pick Segotep when non-modular ATX is part of the plan rather than a compromise against a modular requirement. The limitation is inherent in that same setup-its title and description call it non-modular-so it is not the appropriate match for shoppers specifically looking to connect only selected cables.

Asiahorse is for cable appearance and organization rather than selecting the main power supply. The Snow White four-piece extension kit uses nylon-braided 18AWG cables and includes matching cable combs to keep individual wires evenly spaced. It is a focused choice when you want white 24-pin ATX, CPU, and PCI-E extension runs for a standard ATX power supply arrangement. The $19.99 listed price is far below the power-supply entries, consistent with its extension-kit role. Its limitation is equally clear: this is a cable extension kit, not a power supply, so it addresses routing and presentation while leaving the power-supply selection separate.

Final recommendation by use case

For a listed high-wattage modular ATX / EPS12V unit with cables, choose the Enermax MaxRevo 1350W. For an SFX build centered on a new fully modular supply, choose the EVGA SuperNOVA 450 GM. Select the Segotep 650W when an open-box, non-modular ATX configuration is what you want. If your existing build mainly needs Snow White extensions and cable combs, the Asiahorse 18AWG kit is the dedicated cable-management choice.
