This article covers Thermaltake Toughpower PF1 850W 80+ プラチナ 片面SMD コンパクトデザイン 120mm 油圧ベアリング スマートゼロファン フルモジュラー電源 PS-TPD-0850FNFAPU-1.

Overview

The Thermaltake Toughpower PF1 850W is a fully modular power supply unit that carries 80 PLUS Platinum certification, delivering up to 90% efficiency under typical loads. It supports Intel C6/C7 power states, making it fully compatible with modern processors from both Intel and AMD. Whether you are building a high-end gaming rig or a content creation workstation, this PSU provides stable and clean power delivery. What sets the PF1 apart is its single-sided SMD (Surface Mount Device) design. By placing all IC components on the top side of the PCB, heat buildup on the underside is minimized, allowing the 120mm hydraulic bearing fan to cool the board more effectively. The compact 140mm depth also makes it easier to fit into mid-tower and even some compact ATX cases, leaving more room for cable management. On the acoustics front, the smart zero fan mode keeps the fan completely still when the load is below 30%. This means near-silent operation during everyday tasks like web browsing or document editing. When the system is under heavier load, the fan spins up gradually. A rear switch lets you disable the zero-fan mode if you prefer constant airflow.

Compatibility Guide

Form factor: Standard ATX, 140mm depth (150mm width x 86mm height x 140mm depth). Fits most mid-tower and full-tower cases; also compatible with many compact ATX cases that accept shorter PSUs. Connectors: 1x 24-pin ATX, 2x 4+4-pin CPU/EPS, 4x 6+2-pin PCIe, 8x SATA, 4x peripheral (Molex). Enough for a single high-end GPU or dual mid-range GPUs. Fully modular design: All cables are detachable, so you only use what you need. This greatly simplifies cable routing and improves airflow inside the case. Input voltage: 100V–240V (wide range), active PFC. Works in Japan (100V) and overseas without manual switching.

Product Info

The Thermaltake Toughpower PF1 850W (model PS-TPD-0850FNFAPU-1) launched around 2020 as a mid-to-high-end PSU option. It holds 80 PLUS Platinum certification, meaning at least 89% efficiency at 50% load under 115V input. The unit uses 100% Japanese 105°C-rated capacitors for long-term reliability, and comes with a 10-year warranty. In terms of market positioning, the PF1 sits above Gold-rated units in efficiency but remains competitively priced among Platinum PSUs. Its combination of compact dimensions, single-sided SMD cooling, and smart fan control makes it a well-rounded choice for builders who want Platinum efficiency without paying a premium.

Best Use Cases

High-end gaming PC builders: If you are pairing an RTX 4070 Ti SUPER, RX 7900 XT, or similar GPU with a modern CPU, 850W provides ample headroom. Platinum efficiency keeps heat and electricity costs lower during long gaming sessions. Silence-oriented users: The smart zero fan mode means the PSU fan stays off during light workloads. Combined with a hydraulic bearing fan that is inherently quiet, this PSU is an excellent choice for a home office or bedroom PC. Compact ATX case users: The 140mm depth is shorter than many competing 850W units. This extra space makes cable management easier in cases where the PSU area is tight, such as the Fractal Design Meshify C or NZXT H5 Flow. Who should look elsewhere? Budget-focused builders: Platinum PSUs cost more than Bronze or Gold units. If you are on a strict budget, a quality Gold-rated PSU may offer better value. * Users needing 1000W or more: For dual-GPU setups or future-proofing with an RTX 4090, 850W may be insufficient. Consider the PF1 1000W model or a higher-capacity unit from another brand.

Things to Consider

The smart zero fan feature means the fan does not spin until the load exceeds 30%. While this is great for silence at idle, the fan will spin up during gaming or rendering. If you prefer constant fan operation, you can flip the rear switch to disable zero-fan mode. No native 12VHPWR (12V-2x6) connector is included. For RTX 40-series GPUs, you will need to use the adapter that comes with the graphics card or purchase a separate 12VHPWR cable. * Compared to competitors like the Seasonic Focus Plus Platinum or Corsair RMx series, the PF1 offers a more compact size and unique single-sided SMD cooling. However, its cables are not individually sleeved, and the included accessories are relatively basic. ## FAQ
Q: Can this PSU power an RTX 4070 Ti SUPER? A: Yes, absolutely. The RTX 4070 Ti SUPER has a recommended PSU wattage of around 700W, so 850W provides comfortable headroom. Just note that you will need to use the GPU's included 12VHPWR adapter or buy a separate cable since the PF1 does not come with one. Q: How do I turn off the smart zero fan mode? A: There is a physical switch on the back of the PSU near the AC input. Flip it to the "off" position to disable zero-fan mode, and the fan will spin continuously at a low speed. Flip it back to "on" to re-enable
