PC Power Supplies & Cables: Choose Between SFX, ATX 3.0, and Cable-Focused Options

Choose among four pc power supplies & cables by starting with the designation that matters most: SFX sizing, ATX 3.0 and PCIe 5.0 naming, included cables, condition, or a specific connector callout.

Last updated Aug 24, 2026

Quick take

Choosing pc power supplies & cables is not simply about picking the largest number on a box. A compact SFX designation, ATX 3.0 and PCIe 5.0 wording, cable needs, and product condition can each steer the decision in a different direction. Start with the specification your build plan actually calls for, then use price as the tie-breaker rather than treating all four as interchangeable.

This group spans a compact EVGA model, a used Enermax unit with cables, an MSI model carrying PCIE 5.0 and ATX 3.0 wording, and a Segotep option with a native 12VHPWR cable callout. The listed-price gap between the lowest and highest entries is USD 65.11, so there is room to prioritize a particular label or cable detail.

Listed-price comparison

ModelListed pricePrice position
EVGA SuperNOVA 450 GMUSD 70.00
Enermax MaxRevo 1350WUSD 64.89
MSI MPG A1000GUSD 130.00
Segotep ATX 3.0 PSUUSD 99.99

Decision matrix

  • SFX is an explicit requirement: the EVGA SuperNOVA 450 GM is the only entry carrying an SFX form-factor designation.
  • Used condition suits the plan: the Enermax MaxRevo is the sole used option; the other three are listed as new.
  • Capacitor callout matters to you: MSI specifically names 100% Japanese 105°C capacitors in its description.
  • A native 12VHPWR cable is central to the shortlist: Segotep explicitly names one alongside its PCIe 5.0 wording.

Product notes

EVGA SuperNOVA 450 GM

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

The EVGA SuperNOVA 450 GM works for a build decision led by the SFX form-factor designation. Its named connector set includes 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA, and 4 Pin Peripheral, so the connection types are clearly spelled out. New condition is another straightforward point in its favor. The limitation is the 450W wording in the name: it is a distinct listed power figure, so choose it for the compact-form-factor route rather than assuming it fills the same role as every other model here. Its one-fan cooling entry rounds out a concise, hardware-specific profile.

Enermax MaxRevo 1350W

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

Choose the Enermax MaxRevo 1350W when its 1350W designation and cable-included title fit what you are seeking. The description also names six independent +12V rails and a combined 112A output, useful identifiers for comparing this model's stated electrical layout without trying to rank wattage alone. It is identified as an ATX / EPS12V power supply with a 115-240 VAC voltage range. The clear constraint is condition: this is the used entry in the group. That makes it a sensible route for a shopper comfortable with that designation and drawn to the MaxRevo's included-cable wording.

MSI MPG A1000G

MPG A1000G PCIE 5.0 & ATX 3.0 Gaming Power Supply - Full Modular - 80 Plus Gold

MSI MPG A1000G is aimed at shoppers who want the exact PCIE 5.0 and ATX 3.0 wording in one model name. Beyond that designation, the description calls out 100% Japanese 105°C capacitors, while the attributes identify an ATX form factor. Its connector list names CPU, PCI Express, SATA, 24 Pin, and peripheral connection types, giving it a broad set of stated connection labels. The tradeoff is straightforward: it occupies the highest listed-price position in this comparison. Choose it when those named standards and component callouts matter more than landing at the lower end of the price range.

Segotep ATX 3.0 PSU

Segotep 850W ATX 3.0 Gaming Power Supply PCIe 5.0 Full Modular 80 Plus Gold PSU

Segotep's ATX 3.0 PSU makes sense when the native 12VHPWR cable wording is a key part of the purchase. Its description also specifies flat black cables and directly connects them with cable-management and airflow language. The attributes add a 120mm fan and an up-to-90% efficiency figure; those are individual listed specifications, not a performance ranking against the other models. The tradeoff is its USD 99.99 listed price: it sits above both the Enermax and EVGA figures, while the MSI price is higher. This is a focused choice for shoppers prioritizing the stated cable setup over the lowest entry price.

Final recommendation by use case

  • For a connector-led compact shortlist: choose the EVGA SuperNOVA 450 GM for its explicitly named 24 Pin, CPU, PCI Express, SATA, and peripheral connection types.
  • For a cable-included 1350W model in used condition: choose the Enermax MaxRevo 1350W.
  • For PCIE 5.0 and ATX 3.0 wording in the model name: choose the MSI MPG A1000G.
  • For an ATX 3.0-labelled direction with a native 12VHPWR cable callout: choose the Segotep ATX 3.0 PSU.
