How each alternative compares
EVGA SuperNOVA 750 G2 750W Power Supply
The EVGA SuperNOVA 750 G2 offers 750W of power, which is significantly lower than the 1300W capacity of the original. It retains the 80 Plus Gold efficiency rating and fully modular design, ensuring similar cable management flexibility. However, it is much smaller, measuring 7 inches in length compared to the original’s 12 inches. This compact size makes it easier to fit in standard cases. You should choose this if your system does not require extreme wattage. It provides a reliable foundation for mid-range builds while saving space and reducing overall power draw when full capacity is unnecessary.
EVGA SuperNOVA 850 G+ 850W PSU
The EVGA SuperNOVA 850 G+ delivers 850W, falling short of the original’s 1300W output but still exceeding many standard builds. It shares the 80 Plus Gold efficiency and fully modular construction. Its dimensions are 7.1 inches long, making it considerably shorter than the original’s 12-inch chassis. It features a 135mm fan for quieter operation under load. This unit is ideal if you need more power than 750W but do not require the massive 1300W output. It offers a balanced solution for standard desktop builds, providing robust protection and efficiency in a more manageable form factor.
SilverStone 700W Gold TFX Power Supply
The SilverStone 700W TFX Gold provides 700W, which is less than half the capacity of the original 1300W unit. Its primary advantage is the TFX form factor, measuring only 6.9 inches long and 2.6 inches high. This allows it to fit into compact cases that cannot accommodate the original’s large 12-inch ATX size. It maintains 80 Plus Gold efficiency. You should pick this if physical space is your main constraint. It sacrifices raw power output for a significantly smaller footprint, making it suitable for small-form-factor builds where the original unit simply would not fit.
Lian Li 750W SFX Gold Power Supply
The Lian Li 750W SFX Gold offers 750W, which is lower than the original’s 1300W. It uses the compact SFX form factor, measuring just 4 inches long and 3 inches wide. This is drastically smaller than the original’s 12-inch length. It retains 80 Plus Gold efficiency and full modularity. This unit is designed for small chassis that require reliable power without the bulk of an ATX supply. Choose this if you are building in a small form factor case. It provides essential power and efficiency in a tiny package, though it cannot support the high-wattage demands that the original unit handles easily.
Lian Li 850W White SFX Power Supply
The Lian Li 850W White SFX Gold delivers 850W, which is less than the original’s 1300W. It features the compact SFX form factor, fitting into small enclosures that cannot accept the original’s large size. It maintains 80 Plus Gold efficiency and full modularity. The white color option allows it to match specific aesthetic builds. This is a strong alternative for small-form-factor systems that need more power than 750W but still lack space for an ATX unit. It trades the original’s massive capacity for a specialized, compact design that fits where the original cannot.
Thermaltake Toughpower GF3 1000W ATX 3.1
The Thermaltake Toughpower GF3 1000W ATX 3.1 provides 1000W, which is lower than the original’s 1300W. It shares the ATX form factor and 80 Plus Gold efficiency. Its key difference is support for ATX 3.1 standards and PCIe 5.1 readiness, featuring a 12V-2x6 connector. It is slightly shorter at 6.3 inches compared to the original’s 12 inches. This unit is best for builders prioritizing modern GPU compatibility and cable management. It offers a more contemporary power delivery standard, though it lacks the raw wattage headroom of the original 1300W model.
