Choosing PC power supplies & cables gets difficult when several units share standards language but point toward different priorities. The useful payoff is simple: decide whether form factor, cable routing, color treatment, or a particular capacity label matters most before letting price make the final call.
Quick take
The four listed prices span a USD 60 gap, so cost matters without replacing a clear build requirement. GAMEMAX focuses on white ARGB Smart presentation, Segotep puts specific cable-routing terms front and center, MPG provides a detailed connector line, and EVGA is explicitly identified as SFX. Start with the feature your build actually calls for, then use the price comparison to narrow the field.

| Power supply | Listed price | Price position |
|---|---|---|
| GAMEMAX 1050W ATX 3.0 PCIE 5.0 ARGB Smart | USD 119.99 | |
| Segotep 850W ATX 3.0 Gaming Power Supply | USD 99.99 | |
| MPG A1000G PCIE 5.0 & ATX 3.0 | USD 130.00 | |
| EVGA SuperNOVA 450 GM 450W SFX | USD 70.00 |
Decision matrix
- White presentation: GAMEMAX is the direct match, with WHITE and ARGB Smart in its title.
- ATX 3.0 and PCIe 5.0 wording: GAMEMAX, Segotep, and MPG each name both terms. Treat that as a shared starting point rather than a tie-breaker.
- Cable-routing priority: Segotep explicitly combines fully modular construction, flat black cables, and a native 12VHPWR cable.
- Named connector lineup: MPG and EVGA both list 4+4 CPU, 6+2 PCI Express, SATA, and 4 Pin Peripheral connections. MPG spells the SATA entry as SATA I.
Product notes
GAMEMAX 1050W ATX 3.0 PCIE 5.0 ARGB Smart 80+ Gold Power Supply UNIT (PSU) WHITE
The GAMEMAX unit fits a build where the white finish and ARGB Smart wording are central to component selection. Its 1050W capacity designation and 80+ Gold label make the listing easy to distinguish from the SFX entry and the 850W and 1000W labels. Choose it for that exact mix of color, lighting language, and capacity, not merely because it carries common ATX 3.0 and PCIe 5.0 wording. The limitation is equally concrete: white is a committed visual direction. Shoppers coordinating around black can instead look at the black color specified for Segotep and EVGA.
Segotep 850W ATX 3.0 Gaming Power Supply PCIe 5.0 Full Modular 80 Plus Gold PSU
Segotep brings its cable-management details together in one clear description: fully modular construction, flat black cables, and a native 12VHPWR cable. That trio is the practical reason to select it when cable routing is your primary filter. The title also identifies an 850W unit, while the description names a 120mm fan and Silent Fan mode. Its limitation is a clearly specified black color, so the presentation follows a different direction from GAMEMAX's white treatment. Pick Segotep for the named cable arrangement rather than treating the shared ATX 3.0 and PCIe 5.0 labels as a distinction.
MPG A1000G PCIE 5.0 & ATX 3.0 Gaming Power Supply - Full Modular - 80 Plus Gold
The MPG A1000G suits a shopper drawn to its specific construction language: 100% Japanese 105°C capacitors, a full modular design, and a 1000W designation. It also enumerates 4+4 CPU, 6+2 PCI Express, SATA I, and 4 Pin Peripheral connections. Choose it when those named details line up with your component plan. The compromise is aesthetic specificity: its color is listed as Gold, while the GAMEMAX, Segotep, and EVGA listings use white or black color wording. It is also the highest listed-price entry in the comparison, making its particular feature wording more important to the decision.
EVGA SuperNOVA 450 GM 450W 80 Plus Gold SFX Fully Modular Power Supply. New
EVGA SuperNOVA 450 GM is the direct route when SFX form factor is a hard requirement. The title also names 450W and fully modular construction, while the description adds ECO Mode with a DBB fan. Choose it for that explicitly SFX-focused combination, not as a stand-in for the differently labeled 850W, 1000W, or 1050W units. Its limitation is the 450W designation itself: it sits in a separate numeric group from every other capacity label here. That clear split is useful for narrowing the shortlist, but raw wattage alone should not be treated as a quality ranking.
Final recommendation by use case
If lowest listed price is the deciding factor, EVGA at USD 70.00 is the starting point. Select GAMEMAX when the 1050W designation is the one your build calls for. Segotep fits shoppers prioritizing its 80Plus Gold certification and up-to-90% efficiency wording. MPG A1000G is the match for a search centered on its Compact Size phrase. For an SFX form-factor requirement, EVGA is the specific choice. If none of those uses decides the purchase, let the price table settle the remaining difference rather than treating wattage figures as a quality ranking.
