Shopping for PC power supplies & cables becomes a real decision when your case format, power target, and cable-routing preference pull in different directions. A small enclosure can narrow the form-factor choice, while a modular layout can change how you approach cable management. Condition matters too: a used or open-box unit may suit one build plan, while a new unit may be the priority for another. Decide which constraint comes first before comparing prices.
Quick take
All four carry 80 Plus Gold wording, so that shared certification label does not settle the choice by itself. The listed-price spread is $77.01. Start with case format, stated output, condition, and cable layout as your non-negotiable filters; those distinctions separate the four models more usefully than price order alone.

Decision matrix
- Condition route: New - EVGA SuperNOVA 450 GM and MSI MPG A1000G; used - Enermax MaxRevo; open box - Segotep.
- Cable-layout route: Modular - Enermax, EVGA, and MSI; non-modular - Segotep.
- Case-form-factor route: SFX - EVGA; ATX / EPS12V - Enermax; ATX - Segotep and MSI.
- Output route: 450W, 650W, 1000W, and 1350W are all represented. Treat these as raw listed ratings rather than an automatic winner.
Product notes
Enermax MaxRevo
Choose the Enermax MaxRevo when the six independent +12V rails and multi-GPU-rig wording suit the build you are planning. Its listed USD 64.89 price also places it near the lower end of this comparison. The steel / metal enclosure and 115-240 VAC attributes add context to its stated configuration. The limitation is condition: the MaxRevo is listed as used. It is a focused pick for shoppers comfortable with that condition who want the model's specified rail layout and multi-GPU focus, rather than for someone making new-condition status a first filter from the outset.
EVGA SuperNOVA 450 GM
The EVGA SuperNOVA 450 GM makes sense when its named connector set-24-pin, 4+4 CPU, 6+2 PCI Express, SATA, and 4-pin peripheral-matches the connections being planned. New condition gives it a clear place for buyers who use condition as an early filter. The limiting number is its 450W listed rating, so compare it as that stated capacity rather than assume it is interchangeable with higher-rated entries. Its fully modular description is also useful context for cable-layout planning, and ECO Mode with a DBB fan is named in the description.
Segotep 650W PSU
Segotep's open-box ATX PSU gives a concrete fit for someone looking for the title's 650W rating and the listed 120mm fan. Its connector entry names a 20+4-pin connection. It is deliberately non-modular, a meaningful cable-layout distinction from the three modular models in this group. Open-box condition is the limitation to weigh alongside that fixed-cable design. The Segotep route is most coherent when those stated basics match the build plan; it should not be selected on the assumption that its layout behaves like the modular alternatives do.
MSI MPG A1000G
The MSI MPG A1000G is the natural match when PCIE 5.0 and ATX 3.0 wording are named requirements, with a 1000W rating also stated. It is new and full modular, and the connector list includes 24-pin, 4+4 CPU, 6+2 PCI Express, SATA I, and 4-pin peripheral. The description also names 100% Japanese 105°C capacitors. The limitation is simple: USD 130.00 is the highest listed price in this comparison. That makes the A1000G a specification-led selection rather than the route for a shopper whose first filter is lowest listed outlay.
Final recommendation by use case
- For an SFX build, choose the EVGA SuperNOVA 450 GM.
- For the 1350W listed-output path, choose the Enermax MaxRevo.
- For the lowest listed price, choose the Segotep 650W PSU.
- For PCIE 5.0 and ATX 3.0 requirements, choose the MSI MPG A1000G.
