PC power supplies & cables: match the build before the price
Choosing among pc power supplies & cables is less about finding one universal answer and more about avoiding a mismatch between your build plan and the unit's named format, cable setup, and condition. A compact SFX-focused build, a modular-cabling project, and an ATX 3.0 requirement point to different entries here. Start with the configuration that fits your parts list, then let condition and listed price settle the final choice.
Quick take
These four units serve clearly different shopping scenarios. The Enermax is the modular 1350W route, the EVGA is the SFX-form-factor route, the Segotep is the non-modular ATX route, and the GAMEMAX is the choice with ATX 3.0 and PCIE 5.0 in its title. That separation matters more than picking solely from the lower end of the displayed price range.
Listed price comparison
| Model | Listed price | Relative listed price |
|---|---|---|
| Enermax MaxRevo | USD 64.89 | |
| EVGA SuperNOVA 450 GM | USD 70.00 | |

Decision matrix
- A modular cable plan in an ATX/EPS12V build: choose the Enermax MaxRevo, which is described as fully modular and includes cables.
- An explicit SFX form-factor requirement: choose the EVGA SuperNOVA 450 GM.
- A non-modular ATX configuration: choose the Segotep 650W unit.
- ATX 3.0 and PCIE 5.0 named requirements: choose the GAMEMAX 1050W.
Product notes
Enermax MaxRevo 1350W Modular PC Power Supply 80 PLUS Gold EMR1350EWT w/ Cables
The Enermax MaxRevo is the only 1350W entry in this group, pairing that designation with fully modular cable connectivity and included cables. It is a focused pick when a 1350W modular ATX/EPS12V unit is already on your build list. The listed steel/metal enclosure and 115-240 VAC voltage range add useful identifying detail without changing that basic choice. Its key limitation is condition: this is a used unit. Choose it for its named cable configuration and output designation, rather than assuming the larger number alone determines suitability.
EVGA SuperNOVA 450 GM 450W 80 Plus Gold SFX Fully Modular Power Supply. New
EVGA SuperNOVA 450 GM brings a connector list that includes 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA, and 4 Pin Peripheral. That makes it a focused choice when those named connections are purposeful parts of the build rather than an afterthought. ECO Mode with a DBB fan is also named in its description. Its limitation is the 450W designation: shoppers planning around another output designation should treat it as a different fit, without assuming a numerical order decides suitability. This unit is listed as new.
OPEN BOX 650W Power Supply 80 Plus Gold Non-Modular ATX Gaming PC Case PSU
The Segotep 650W unit carries a 20+4 Pin connector, one 120mm fan, and an 80 Plus Gold efficiency designation. It is a direct fit for a buyer who has already chosen a 650W ATX case PSU and wants the stated connector arrangement. The 650W designation makes its intended place in this comparison easy to identify without claiming that it suits every system. Its main limitation is the open-box condition. Weigh that condition alongside the specified configuration, rather than treating it as interchangeable with either used or new units.
GAMEMAX 1050W ATX 3.0 PCIE 5.0 ARGB Smart 80+ Gold Power Supply UNIT (PSU) WHITE
The GAMEMAX 1050W has the highest listed price in this comparison. Its title combines a 1050W designation, 80+ Gold certification, and a white finish, while its style is identified as RGB1050-PRO. Choose it when that combination is central to your shortlist, not solely because of a larger output number. The limitation is cost: USD 119.99 sits at the top of the displayed range. It is also listed as new, distinguishing its condition from the used and open-box entries.
Final recommendation by use case
- Used-condition modular choice: Enermax MaxRevo 1350W is the appropriate route when a used unit is acceptable.
- Compact-format plan: EVGA SuperNOVA 450 GM is the match for the SFX-focused build path, with its named connector selection.
- Open-box 650W plan: Segotep GN-650 is the direct choice when that condition and output designation fit your shortlist.
- ATX 3.0 and PCIE 5.0 build requirement: GAMEMAX 1050W is the clear match when those terms are part of the specification you are shopping for.
