Choosing pc power supplies & cables becomes harder when connectors, cable layout, color treatment, and the space your case allows matter alongside the wattage printed on the unit. In this group, three new models name ATX 3.0 and PCIe 5.0, while the SilverStone entry carries a 300W designation. Start with the configuration your build calls for, then treat wattage numbers as neutral specifications rather than a shortcut to the right answer.
Quick take
These are not four interchangeable choices. Establish your case requirement and power target first, then narrow the field with the specific cable and connector names relevant to your parts list. The price span is substantial, but condition and visual direction can be equally decisive.
Listed price comparison
The $65 gap is useful for setting an upper limit, but it does not erase the configuration differences among the four choices.

Product notes
GAMEMAX 1050W ATX 3.0 PCIE 5.0 ARGB Smart 80+ Gold Power Supply UNIT (PSU) WHITE
The GAMEMAX serves shoppers whose build brief starts with a white component and ARGB Smart styling. Its title also names ATX 3.0 and PCIe 5.0, putting those platform labels in the same configuration. This is a natural route when visual presentation is a priority alongside those standards. The limitation is equally concrete: white ARGB styling is highly specific, so it is not the visual match for a black component plan. At USD 119.99, it is USD 19.99 above the Segotep. Pick it for the white ARGB look rather than treating its wattage figure as the deciding factor.
Segotep 850W ATX 3.0 Gaming Power Supply PCIe 5.0 Full Modular 80 Plus Gold PSU
Segotep makes a cable-focused case because it explicitly pairs flat black cables with a native 12VHPWR cable. The flat-cable design is connected with airflow and cable management, providing a specific reason to choose it when those details are already part of the build plan. Its 80 Plus Gold certification is another stated characteristic. Styling is the limitation: its black color does not match the white presentation of GAMEMAX. Select Segotep for the named cable arrangement, rather than when a white component is the visual priority.
MPG A1000G PCIE 5.0 & ATX 3.0 Gaming Power Supply - Full Modular - 80 Plus Gold
MSI's connector list is explicit: 4+4 CPU, 4 Pin Peripheral, 6+2 Pin PCI Express, 24 Pin, and SATA I. That terminology gives a shopper with a defined component list a direct way to compare the connectors named here. The MPG A1000G is also identified as full modular in its title. Its constraint is price: USD 130.00 is the group high, USD 10.01 above GAMEMAX. Choose it when the named connector lineup is the deciding detail; it is a less suitable route when the lowest listed upfront price is the main filter.
SilverStone SST-ST30SF SFX Form Factor 300W 80Plus Bronze Power Supply
SilverStone is the compact-form-factor entry, with SFX named in the title and a 300W maximum power figure. It also identifies 20 Pin, 20+4 Pin, 24 Pin, and 8 Pin 12V connectors, plus an 80Plus Bronze designation. The 300W designation gives shoppers targeting that figure a direct reason to consider it. The key limitation is condition: this is an open-box unit, unlike the three new entries. Its USD 65.00 price is the group low, but the decision should stay centered on its stated configuration.
Final recommendation by use case
- White ARGB build: Choose GAMEMAX for the white ARGB Smart styling.
- Cable-management-led build: Segotep is the relevant match for flat black cables and the native 12VHPWR cable.
- Connector-specific component list: MSI fits this route because it names CPU, peripheral, PCI Express, 24 Pin, and SATA I connectors.
- SFX form-factor requirement: SilverStone is the direct match, with SFX explicitly named.
