How Alternative Power Supplies Compare
Apevia Spirit 600W ATX Power Supply
The Apevia Spirit 600W drops total capacity to 600 watts compared to the 700-watt output of the Spirit 700W. While both units share an ATX form factor and a 120mm fan, this model gives up 100 watts of headroom and does not match the 53A single +12V rail output of the 700W unit. Its layout covers standard computer hardware without supporting higher-draw components. You retain multi-rail protection for your hardware across common desktop workloads. Pick this power supply if you are assembling a basic desktop configuration that comfortably operates within a 600-watt envelope and does not need the extra headroom of a 700-watt unit.
Thermaltake Toughpower GX3 850W Gold PSU
The Thermaltake Toughpower GX3 850W upgrades your capacity to 850 watts, exceeding the Spirit 700W by 150 watts. It improves efficiency with an 80 Plus Gold rating, whereas the Spirit 700W lacks rated Gold performance. Modern platform support is a key addition: the GX3 brings ATX 3.1 and PCIe 5.1 specifications, including a dedicated 12V-2x6 connector alongside standard cabling, supported by a 5-year warranty. Both units utilize 120mm cooling fans and ATX dimensions. You trade away the basic legacy cable configuration of the 700W unit for modern power standards. Choose the GX3 850W if you are building an ATX 3.1 system that requires higher wattage and dedicated modern GPU connections.
The HIGH Power 750W increases total output by 50 watts over the Apevia Spirit 700W while upgrading platform compatibility. Unlike the original unit, this model meets ATX 3.1 and PCIe 5.1 specifications and incorporates Active Power Factor Correction alongside an 80 Plus Gold efficiency certification. Both power supplies use 120mm fans for cooling. The HIGH Power unit is physically larger at 10 inches long and 8 inches wide, compared to the 5.9-inch length of the Spirit 700W, requiring more case room. You should select this alternative if you need modernized ATX 3.1 delivery, Active PFC, and verified Gold efficiency for mid-tier hardware rather than basic 700W delivery.
The Apevia Venus 500W scales down output to 500 watts, providing 200 watts less overall power than the Spirit 700W. It features a reduced connectivity layout, offering a single PCIe connector and three SATA ports, whereas the Spirit 700W supplies two 6+2pin PCIe plugs and four SATA connections. Both models come in standard ATX enclosures with 120mm fans and essential electrical safety protections. The Venus 500W gives up multi-GPU support and high-draw single-rail capacity. You should choose this model if you are assembling an entry-level desktop with lower energy demands that only requires a single PCIe connection and fewer peripheral drives.
The Enermax MAXPRO IV 750W provides 50 watts more capacity than the 700W Spirit. It brings verified 80 PLUS efficiency, Japanese primary capacitance, and continuous power delivery rated up to 40°C. Like the Spirit 700W, it utilizes fixed, non-modular cabling and a 120mm fan, and it does not feature ATX 3.1 specifications. While the Spirit 700W highlights a 53A single +12V rail and dual 6+2pin PCIe connectors, the MAXPRO IV focuses on component durability under operating heat. Pick this 750-watt unit if you want verified 80 PLUS operation and higher-grade Japanese capacitance for a standard desktop gaming build without changing to modular cables.
The Enermax MAXPRO IV 550W reduces maximum delivery to 550 watts, giving up 150 watts compared to the Spirit 700W. However, it incorporates Japanese main capacitors and holds an official 80 PLUS efficiency rating, specs not present on the Spirit 700W. Both units feature ATX sizing, non-modular wiring, and a 120mm cooling fan. By picking the 550W version, you lose the heavy 53A single-rail output and overall capacity intended for 700-watt systems. Choose this power supply if your gaming setup runs comfortably on 550 watts and you prioritize Japanese capacitors and certified 80 PLUS efficiency over maximum wattage headroom.
