PC Power Supplies & Cables: Choose Between SFX, ATX 3.0, and Higher-Wattage Options

Choose an SFX modular unit, a used 1350W model with cables, or a new ATX 3.0 and PCIe 5.0 power supply by prioritizing form factor, condition, capacity, and listed price.

Last updated Aug 24, 2026

Choosing pc power supplies & cables means balancing the form factor your case calls for, the cable setup you want, the listed connector selection, and the capacity you are shopping for. The four choices here split into clear paths: an SFX fully modular unit, a used high-capacity model sold with cables, and two new ATX 3.0 and PCIe 5.0 options. Start with the build requirement that cannot change, then let condition and price narrow the field.

Quick take

The EVGA SuperNOVA 450 GM is the direct route for an SFX build with a fully modular layout. Enermax stands apart as the used 1350W choice with cables named in the title. MSI is the fully modular ATX entry whose title explicitly includes both PCIe 5.0 and ATX 3.0, while GAMEMAX pairs 1050W, ATX 3.0, PCIe 5.0, and a white finish. Prices run from $64.89 to $130, so the condition and configuration differences matter as much as the price range.

Decision matrix

  • SFX form factor is a fixed requirement: Choose the EVGA SuperNOVA 450 GM.
  • Lowest listed price and a title that includes cables: Choose the Enermax MaxRevo 1350W, accepting its used condition.
  • Full modular design with PCIe 5.0 and ATX 3.0 wording: Choose the MSI MPG A1000G.
  • A white 1050W ATX 3.0 and PCIe 5.0 unit: Choose the GAMEMAX 1050W.

Product notes

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

The EVGA case rests on its specific pairing of an SFX form factor and fully modular design. Its connector list includes 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA, and 4 Pin Peripheral connections, giving a shopper concrete cable categories to work from. Choose it when the listed SFX format is the central requirement and detachable cabling is part of the plan. The limitation is its listed 450W capacity, which puts it in a different capacity range from the 1000W, 1050W, and 1350W entries. It is new, and its description also names ECO Mode with a DBB fan.

Enermax is the choice for someone prioritizing a 1350W model whose title includes cables and whose description specifies fully modular cable connectivity. It also carries the lowest listed price in this comparison. The MaxRevo description names six independent +12V rails with up to 112A combined output, while its attributes identify it as an ATX/EPS12V power supply. Its important trade-off is condition: this is the only used unit among the four. That makes it a distinct route for shoppers comfortable selecting a used power supply rather than one of the three new alternatives.

The MSI MPG A1000G fits a shopper looking specifically for PCIe 5.0 and ATX 3.0 in the title alongside a full modular design. Its description identifies a 1000W rating, an ATX form factor, and 100% Japanese 105°C capacitors. The listed connector selection includes 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA I, and 4 Pin Peripheral connections. At $130, it is the highest-priced choice here, so it makes most sense when its stated configuration is more important than starting at the lower end of the price range. It is listed as new.

The GAMEMAX 1050W is the clear match for a shopper who wants the title's white finish together with 1050W, ATX 3.0, PCIe 5.0, and 80+ Gold wording. It is listed as new, and its description positions it for gaming and office use. This makes it a visually specific alternative to the black EVGA model and the gold-colored MSI entry. The limitation is its $119.99 price, which places it near the upper end of this four-item range. Choose it for the combination of its white presentation and its explicitly named platform terms, rather than as the low-price route.

Final recommendation by use case

For an SFX-focused build, select the EVGA SuperNOVA 450 GM. Pick the Enermax MaxRevo 1350W when a used unit with cables and the lowest listed price is the right balance. The MSI MPG A1000G is the focused choice for full modular PCIe 5.0 and ATX 3.0 wording. Choose the GAMEMAX 1050W when the white finish and its 1050W ATX 3.0 and PCIe 5.0 title details fit the build you have in mind.
