Choosing pc power supplies & cables gets tricky when the choices are not interchangeable: three are complete power supplies with different wattage labels and form factors, while one is a short connection cable for named NVIDIA TESLA hardware. Start by deciding whether the job calls for a full supply or a specific dual PCIe-to-CPU connection. Then narrow the complete-supply choices by the wattage, form-factor, cable design, and condition that fit your parts plan.
Quick take
The Enermax MaxRevo is the modular 1350W choice and includes cables. EVGA's SuperNOVA 450 GM is the new, fully modular SFX route, while the Segotep is an open-box 650W non-modular ATX supply. The Dual PCIe 8Pin to CPU 8Pin cable is a 12.5CM item named for NVIDIA TESLA K80, P40, and P100 hardware rather than a complete supply.
Listed price comparison
| Item | Listed price | Relative listed-price bar |
|---|---|---|
| Enermax MaxRevo 1350W | USD 64.89 | |
| EVGA SuperNOVA 450 GM | USD 70.00 | |
| Segotep 650W ATX | USD 52.99 | |
| Dual PCIe 8Pin to CPU 8Pin Tesla Cable | USD 9.90 |
The four listed prices span USD 9.90 to USD 70.00, but the cable belongs in a different purchase decision from the three complete power supplies. Among the supplies, the Segotep carries the lowest listed price, followed by the Enermax, with the EVGA at the top of this group's listed range.
Decision matrix
- Choose the Enermax MaxRevo when your build plan specifically calls for a multi-rail +12V arrangement. It describes six independent +12V rails with up to 112A combined output.
- Choose the EVGA SuperNOVA 450 GM when its connector set matches your requirements: 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA, and 4 Pin Peripheral are all named.
- Choose the Segotep 650W ATX when a 120mm fan is part of the specification you want to prioritize. Its listed condition is open box.
- Choose the Dual PCIe 8Pin to CPU 8Pin Tesla Cable when you need the exact dual PCIe 8Pin to CPU 8Pin connection described in its name.
Product notes
Enermax MaxRevo 1350W
The MaxRevo has a specific reason to stand out beyond its wattage label: it describes six independent +12V rails with up to 112A combined output. That makes it a sensible match for a build plan seeking that named multi-rail configuration. A steel/metal enclosure is also specified, and the 80 PLUS Gold designation appears with the MaxRevo model. The important limitation is condition, as this unit is marked Used. Its ATX / EPS12V classification further separates it from the SFX-labelled EVGA route, so the form factor should be part of the initial decision.
EVGA SuperNOVA 450 GM
The SuperNOVA 450 GM is compelling when the listed connector selection is the deciding factor: it includes 24 Pin, 4+4 CPU, 6+2 Pin PCI Express, SATA, and 4 Pin Peripheral connections. It is also marked New, which distinguishes it from the Used Enermax and Open box Segotep. The trade-off is its 450W designation; the other complete supplies here are labelled 650W and 1350W. Those are simply different listed capacities, not a performance ranking. Let the SFX format and connector requirements lead the choice rather than wattage alone.
Segotep 650W ATX
A stated 120mm fan gives the Segotep a clear selection reason when that fan size belongs on your parts checklist. The 80 Plus Gold certification is named consistently, and the supply also lists a 20+4 Pin connector. Its concrete limitation is the non-modular design, which is a different cable approach from the modular Enermax and EVGA units. The condition is Open box, another meaningful distinction within this comparison. Treat the 650W figure as the listed capacity rather than a shortcut for judging it against the 450W and 1350W alternatives.
Dual PCIe 8Pin to CPU 8Pin Tesla Cable
This cable is the focused choice for the named NVIDIA TESLA K80, P40, and P100 use case, with a 12.5CM length included in its name. It is marked New and is explicitly identified as a cable, making its role much narrower than the three power-supply listings. That focus is also its limitation: it is not a complete power supply for a PC build. Select it only when the needed task is the stated PCIe 8Pin-to-CPU 8Pin connection, rather than when you are choosing the main supply for a case.
Final recommendation by use case
For a plan centered on a 1350W modular supply with cables, take the Enermax MaxRevo. Choose the EVGA SuperNOVA 450 GM when the build calls for an SFX, fully modular supply. The Segotep fits the ATX route when its 650W label and non-modular design are acceptable. Pick the Dual PCIe 8Pin to CPU 8Pin Tesla Cable only for its stated adapter role; it answers a cable need, not the need for a complete PC power supply.
