The EVGA Supernova 1300 G+ 1300W Gold PSU delivers stable high-capacity output for high-draw workstations and multi-GPU systems. You might look for evga supernova 1300 g alternatives if your build requires different specifications. The original unit provides 1300W of power with 80 PLUS Gold efficiency and fully modular cabling. It also includes a 10-year warranty and a 140mm fan for quiet operation. However, not every system needs that much capacity or those exact dimensions.
You may need a lower wattage option for a mid-range build. Some users prefer modern ATX 3.0 or 3.1 standards for new PCIe connectors. Others might want a different brand or a slightly smaller form factor to fit a compact case. This list covers 6 alternatives that share key specs with the original. We selected these options because their efficiency ratings, modularity, or warranty periods overlap with the EVGA Supernova 1300 G+. Each choice offers a distinct advantage for specific use cases while maintaining reliable power delivery.
How the alternatives differ
EVGA 650W G6 Gold PSU
The EVGA 650W G6 Gold PSU drops wattage significantly to 650W, making it unsuitable for high-draw workstations. It retains the 80 PLUS Gold efficiency rating and fully modular cabling found in the original. The 10-year warranty matches the G+ model exactly. You should choose this if your system does not exceed 650W. The smaller form factor fits tighter cases better. It lacks PCIe 5.0 connectors, so it is best for mid-range builds. You save space and cost by reducing capacity, but you lose the headroom needed for multi-GPU setups.
Seasonic Focus V3 GX-750 ATX 3.0 PSU
The Seasonic Focus V3 GX-750 offers 750W of power, which is lower than the 1300W original. It includes ATX 3.0 compliance and native PCIe 5.0 cabling, features the EVGA G+ lacks. Both units hold 80 PLUS Gold efficiency and fully modular designs. The Seasonic unit also provides a 10-year warranty. You should pick this for modern builds needing updated connectors. It is a compact alternative for systems that do not require extreme wattage. The trade-off is lower total power output. You gain modern connectivity standards but sacrifice the massive capacity of the 1300W EVGA unit.
MSI MAG 850W Fully Modular ATX Power Supply
The MSI MAG 850W PSU provides 850W of output, falling short of the 1300W original. It features ATX 3.1 compliance and PCIe 5.1 support, which the EVGA G+ does not have. Both units are fully modular and carry 80 PLUS Gold efficiency ratings. The MSI unit includes a 10-year warranty. You should select this for gaming systems needing newer power standards. It offers a balance of modern connectivity and moderate power. You give up significant wattage headroom. This unit suits gamers who prioritize updated PCIe connectors over maximum total power delivery.
EVGA SuperNOVA G2 1300W Fully Modular PSU
The EVGA SuperNOVA G2 1300W matches the original wattage and efficiency rating exactly. It is fully modular and includes a 10-year warranty. The G2 uses a 140mm dual ball bearing fan, whereas the G+ uses a fluid dynamic bearing fan. Both units target high-draw systems. You might choose the G2 if you prefer dual ball bearing fans. The G+ includes an ECO mode for quiet operation, which the G2 data does not specify. The G2 is a solid alternative for users wanting similar specs. It provides heavy-duty protections and similar form factors. You get comparable performance with a different fan bearing type.
EVGA SuperNOVA 750 G2 750W Power Supply
The EVGA SuperNOVA 750 G2 750W PSU reduces power to 750W, significantly less than the 1300W original. It maintains 80 PLUS Gold efficiency and fully modular cabling. The warranty is also 10 years. You should pick this for moderate-power builds that do not need four-digit wattage. It is a downsized alternative for systems with lower power requirements. The physical dimensions are smaller, fitting more cases. You sacrifice half the power capacity. This unit is ideal if your hardware draws less than 750W. You retain EVGA reliability and efficiency ratings without the bulk of the larger unit.
EVGA SuperNOVA 1600W Fully Modular PSU
The EVGA SuperNOVA 1600W PSU increases wattage to 1600W, exceeding the 1300W original. It shares the 80 PLUS Gold efficiency rating and fully modular design. The warranty remains 10 years. It uses a 140mm double ball bearing fan. You should choose this for multi-GPU systems that outgrow 1300W units. It provides extra headroom for demanding hardware. The G+ lacks this higher capacity option. You gain significant power output but may need more case space. This unit is best for users who need maximum power delivery. You trade the specific ECO mode features of the G+ for higher total wattage.
