As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You are looking at thermaltake toughpower grand mining crytocurrency alternatives for a build that needs reliable 850W power. The original Thermaltake Toughpower Grand 850W Gold PSU delivers continuous power at high temperatures with 80 PLUS Gold efficiency. It uses a large 14cm fan and fully modular cables for clean cable management. However, its ATX 12V 2.3 standard may not support modern graphics cards that require newer power delivery protocols.
You might want a different spec, size, or brand if your system uses PCIe 5.1 GPUs or fits in a smaller case. The alternatives were chosen because their specs overlap with the original, offering 850W output and 80 PLUS Gold efficiency. Some options provide ATX 3.1 compliance, side-mounted connectors, or compact SFX form factors. These selections cover a range of use cases, from standard ATX builds to Mini-ITX systems, ensuring you find a power supply that matches your specific hardware requirements and case dimensions.
Comparing the Top 850W Alternatives
The Corsair RM850x Shift updates your power infrastructure to ATX 3.1 and PCIe 5.1 specifications, whereas the Thermaltake relies on the legacy ATX 12V 2.3 standard. It also offers a significantly smaller chassis measuring 6.3 by 5.91 by 3.39 inches, compared to the Thermaltake unit's 13.3-inch length. At 3.75 pounds, it is notably lighter than the 6-pound original. However, you give up the Thermaltake PSU's 14cm dual ball bearing fan and its guaranteed continuous 850W delivery rating at 50°C. You should pick this unit if you want modern ATX 3.1 power support, fully modular cables, and a white finish for a compact PC enclosure.
MSI MPG 850W Gold ATX 3.1 Power Supply
The MSI MPG A850G PCIE 5 advances past the original unit by providing ATX 3.1 and PCIe 5.1 compliance alongside a dedicated 12V-2x6 connector. It matches the original's use of Japanese capacitors while adding an explicit 10-year warranty. Its chassis is much shorter at 5.91 inches in length, taking up less room than the 13.3-inch Thermaltake frame. On the other hand, it weighs more at 7.15 pounds versus 6 pounds, and it does not list the 14cm fan or the 50°C continuous load rating of the original. You should choose this model if you need native 12V-2x6 GPU power and modern ATX 3.1 specifications.
Montech Century G5 850W Power Supply
The Montech Century G5 provides an upgrade to ATX 3.0 standards, which modernizes your system compared to the Thermaltake unit's ATX 12V 2.3 specification. It also features a significantly smaller footprint, measuring 5.51 inches long, 5.9 inches wide, and 3.38 inches high, easily fitting cases where the 13.3-inch Thermaltake model struggles. You give up the dual ball bearing 14cm fan design, the Japanese capacitor specification, and the 50°C continuous operation rating that came with the original. Choose the Century G5 if you need an ATX 3.0 compliant 850W power supply in a compact size for modern PCIe 5.0 graphics cards.
The ASRock Steel Legend White brings modern ATX 3.1 power delivery and a dedicated 12V-2x6 connector, whereas the Thermaltake PSU operates under ATX 12V 2.3 guidelines. It is notably smaller, measuring 5.91 by 5.91 by 3.39 inches compared to the 13.3-inch length and 8.27-inch width of the original unit. However, this power supply weighs slightly more at 6.59 pounds, and its specifications do not detail the 14cm fan diameter or the 50°C continuous output threshold of the Thermaltake model. You should choose this unit if you want updated ATX 3.1 connectivity and direct 12V-2x6 cabling in a compact, white chassis.
The MSI MPG A850GS PCIE5 modernizes your configuration by offering ATX 3.1 and PCIe 5.1 compliance, along with a 12V-2x6 connector and a 10-year warranty. Like the original, it uses Japanese capacitors to maintain dependable power delivery. Its dimensions of 11.5 by 9.5 by 5.4 inches make it somewhat shorter than the 13.3-inch Thermaltake frame, though it is slightly heavier at 6.83 pounds versus 6 pounds. You lose the original's 14cm flower-shaped fan and its certified continuous 850W delivery at 50°C. Select this power supply if you require dual 12V-2x6 connections and native PCIe 5.1 support for your graphics cards.
The Montech Century II steps up to ATX 3.1 standards and PCIe 5.1 compatibility, which the older ATX 12V 2.3 Thermaltake design lacks. It features Japanese capacitors and a 10-year warranty, while weighing less at 4.63 pounds compared to the 6-pound original. However, you miss out on the Thermaltake PSU's 14cm dual ball bearing fan and its guaranteed continuous 850W power rating at 50°C. Its square 10-inch enclosure also has different clearance requirements than the original's 13.3 by 8.27-inch dimensions. Choose the Century II if you want current ATX 3.1 power delivery, Japanese capacitors, and long warranty coverage in a silver finish.
