Choosing PC power supplies & cables is less about picking the largest number in a title and more about matching the unit to the connections, cable layout, condition, and platform language your build calls for. Here, the real split is between an open-box non-modular ATX unit, two new modular ATX 3.0/PCIe 5.0 choices, and a used Enermax model sold with cables.
Quick take
The Segotep 650W is the entry for shoppers comfortable with an open-box, non-modular format. The Segotep ATX 3.0 and MSI MPG A1000G are both listed as new and fully modular, but they speak to different priorities: the Segotep calls out ATX 3.0 and PCIe 5.0, while the MSI names a broad connector assortment. The Enermax MaxRevo is used and carries the MaxRevo 1350W model designation, plus cables in its title. Start with the build detail that matters most rather than treating wattage alone as the deciding factor.
Listed-price comparison
| Power supply | Listed price | Price position |
|---|---|---|
| Segotep 650W open-box ATX | USD 52.99 | |
| Segotep ATX 3.0 / PCIe 5.0 | USD 99.99 | |
| MSI MPG A1000G | USD 130.00 | |
| Enermax MaxRevo | USD 64.89 |
Decision matrix
- Lowest listed-price route: the open-box Segotep 650W at USD 52.99.
- Build brief specifically naming ATX 3.0 and PCIe 5.0: the Segotep 850W ATX 3.0 Gaming Power Supply, where both standards appear in the title.
- Need for a stated CPU, peripheral, PCI Express, 24 Pin, and SATA I connector list: the MSI MPG A1000G.
- Searching for the Enermax EMR1350EWT model: the MaxRevo entry identifies that model number directly.
Product notes
OPEN BOX 650W Power Supply 80 Plus Gold Non-Modular ATX Gaming PC Case PSU
The 20+4 Pin connector and ATX form factor make this Segotep an easy match for shoppers specifically seeking those listed specifications. Its 120mm fan is another clear component detail, and the 80 Plus Gold designation is shared across all four choices here. The trade-off is stated plainly in the name: this is a non-modular power supply in open-box condition. Choose it when those condition and cable-format terms suit the build plan, rather than when a fully modular layout is the central requirement. It is the straightforward pick for a shopper whose starting point is the lowest listed price.
Segotep 850W ATX 3.0 Gaming Power Supply PCIe 5.0 Full Modular 80 Plus Gold PSU
This Segotep is aimed squarely at a parts list that calls out ATX 3.0 and PCIe 5.0. Beyond those title details, it names a native 12VHPWR cable and flat black cables within a fully modular design, giving cable organization a concrete role in the decision. It is listed as new, a condition shared with the MSI option. The limitation is its USD 99.99 listed price, which places it above the open-box Segotep and used Enermax. Pick this one when its named standards and native cable are more relevant to your plan than the lower starting-price choices.
MPG A1000G PCIE 5.0 & ATX 3.0 Gaming Power Supply - Full Modular - 80 Plus Gold
MSI's MPG A1000G stands out for its stated connector assortment: 4+4 CPU, 4 Pin Peripheral, 6+2 Pin PCI Express, 24 Pin, and SATA I are all named. The title and description both identify a fully modular, 80 Plus Gold ATX design, while the 1000W specification is consistent with the model name. It is also listed as new. Its clearest limitation is the USD 130 listed price, the top end of this comparison. This is the focused choice when the named connector list is the key reason for selecting a power supply, rather than simply choosing by condition or entry price.
Enermax MaxRevo 1350W Modular PC Power Supply 80 PLUS Gold EMR1350EWT w/ Cables
The Enermax MaxRevo EMR1350EWT is the choice for shoppers seeking its 1350W model designation and ATX/EPS12V type. Its description specifies modular cable connectivity, while "w/ Cables" appears in the title, making the cable-focused positioning especially direct. The listed 50-60 Hz frequency range and 115-240 VAC voltage are additional electrical details, but they do not establish a ranking against the other units. The limitation is condition: this Enermax is used, unlike the new Segotep ATX 3.0 and MSI offerings. Choose the exact MaxRevo model when that condition is acceptable and the included-cables wording aligns with the purchase.
Final recommendation by use case
Choose the open-box Segotep 650W for a build plan centered on a 20+4 Pin ATX power supply. Select the Segotep ATX 3.0 model when a native 12VHPWR cable is part of the requirement. The MSI MPG A1000G makes the most sense when the listed 1000W capacity and connector assortment are the deciding details. Pick the Enermax MaxRevo when the EMR1350EWT model and its 115-240 VAC specification are the terms you are shopping around, with its used condition already factored into the choice.
