Choosing pc power supplies & cables comes down to a few decisions that cannot be solved by wattage alone: whether your build calls for an SFX format or an ATX unit, whether modular cabling matters for routing, and whether you want ATX 3.0 and PCIe 5.0 named in the specification. The four choices here span a used 450W SFX supply through new 850W, 1000W, and 1050W options. The practical shortcut is to match the format and cable setup named for your build first, then use price and finish to break the tie.
Quick take
The Silver Stone SST-ST45SF is the clear format-specific choice because its title identifies it as an SFX power supply. For an ATX 3.0 build where cable management is central, the Segotep 850W explicitly combines full modular construction, flat black cables, and a native 12VHPWR cable. The MSI MPG A1000G is another full-modular ATX 3.0 route with a named connector list, while the GAMEMAX 1050W is the pick for shoppers who want a white ARGB-styled unit and the highest wattage named here.
Listed prices run from USD 65.00 to USD 130.00, a USD 65.00 spread. Condition also divides the group: the Silver Stone unit is used, while the other three are new.
Listed price comparison
| Power supply | Listed price | Price position |
|---|---|---|
| Silver Stone SST-ST45SF 450W SFX | USD 65.00 | |
| Segotep 850W ATX 3.0 Full Modular | USD 99.99 | |
| GAMEMAX 1050W ATX 3.0 ARGB | USD 119.99 | |
| MSI MPG A1000G ATX 3.0 Full Modular | USD 130.00 |
Decision matrix
- Need the SFX format: Choose the Silver Stone SST-ST45SF. It is the only model identified as SFX, and it is also the used choice in this group.
- Want explicitly described cable-routing features: Choose the Segotep 850W. Its full-modular layout and flat black cables are specifically positioned for airflow and cable management.
- Need a named multi-connector setup: The MSI MPG A1000G lists 4+4 CPU, 6+2 PCI Express, 24-pin, SATA I, and 4-pin peripheral connectors.
- Building around a white ARGB look: The GAMEMAX 1050W is the only white, RGB-styled model named here.
- Prioritizing ATX 3.0 and PCIe 5.0 wording: GAMEMAX, Segotep, and MSI all name both standards; the Silver Stone title instead emphasizes SFX and 80 Plus Bronze.
Product notes
GAMEMAX 1050W ATX 3.0 PCIE 5.0 ARGB Smart 80+ Gold Power Supply UNIT (PSU) WHITE
The GAMEMAX is aimed at a build where the power supply is part of the visual plan rather than an unseen component. Its white finish and ARGB Smart styling give it a distinctly decorative direction, while the title also names ATX 3.0, PCIe 5.0, 80+ Gold, and 1050W. That makes it a sensible match for shoppers specifically seeking those labels alongside RGB presentation. The limitation is price positioning: at USD 119.99, it sits above the Segotep 850W in this comparison. It is also not described as fully modular, so shoppers focused on that particular cable-layout feature have clearer wording from the Segotep and MSI alternatives.
Segotep 850W ATX 3.0 Gaming Power Supply PCIe 5.0 Full Modular 80 Plus Gold PSU
For a cleaner cable-management brief, the Segotep gives the most direct explanation of its approach: it is fully modular and includes flat black cables intended to improve airflow and cable management. ATX 3.0, PCIe 5.0, 80 Plus Gold, and a native 12VHPWR cable are all part of its stated setup, making the model easy to place in a modern gaming-oriented parts list. USD 99.99 keeps it in the middle of the four listed prices. Its trade-off is the 850W figure in the title; shoppers choosing strictly between the named capacities will find 1000W and 1050W alternatives in the MSI and GAMEMAX models.
MPG A1000G PCIE 5.0 & ATX 3.0 Gaming Power Supply - Full Modular - 80 Plus Gold
The MSI MPG A1000G suits shoppers who want a full-modular ATX unit with a clearly stated set of connectors. The listing names CPU, PCI Express, motherboard, SATA, and peripheral connections, and the description adds Japanese 105°C capacitors. PCIe 5.0, ATX 3.0, and 80 Plus Gold are consistently central to its positioning. Choose it when the named connector assortment and modular design fit your build plan. The main limitation is simple: USD 130.00 is the highest listed price here. Its gold color is also a more specific styling cue than the GAMEMAX's white ARGB presentation, so appearance-focused shoppers may prefer the latter's look.
Silver Stone SST-ST45SF 450W SFX 80 Plus Bronze Power Supply
The Silver Stone SST-ST45SF is the straightforward choice when SFX is the deciding requirement. Its title explicitly pairs the compact-form-factor label with 450W and 80 Plus Bronze, rather than presenting another ATX 3.0 gaming supply. At USD 65.00, it occupies the lowest listed-price position, which may matter when format is already settled. The limitation is condition: this unit is used and described as showing scratches from prior use. It also does not carry the ATX 3.0, PCIe 5.0, full-modular, or ARGB wording found across the other options, so it serves a more focused SFX-oriented brief.
Final recommendation by use case
Pick the Silver Stone SST-ST45SF for an SFX-focused build and a lower entry price. Choose the Segotep 850W when full modular cabling, flat black leads, and a native 12VHPWR cable are the strongest priorities. Go for the MSI MPG A1000G if a full-modular ATX 3.0 design with its named connector mix is worth the highest listed price. Select the GAMEMAX 1050W when a white ARGB power supply and the 1050W designation best match the build you have in mind.
