Thermaltake TOUGHPOWER GF3 1000W PC電源ユニット

This article covers Thermaltake TOUGHPOWER GF3 1000W PC電源ユニット.

Overview

The Thermaltake TOUGHPOWER GF3 1000W is a high-end ATX 3.0 compatible power supply with 80PLUS GOLD certification. Its standout feature is the native 12VHPWR connector (16-pin) that delivers up to 600W via a single cable, making it an excellent match for modern flagship graphics cards. With a 1000W continuous rating, this PSU provides ample headroom for gaming rigs and creative workstations alike. Built with Japanese 105°C electrolytic capacitors and a Smart Zero Fan mode (fans stop under 30% load), it delivers low ripple noise (below 30mV on all rails) and quiet operation. The unit comes with a 10-year warranty, promising long-term reliability for your investment.

Compatibility Guide

Standard ATX form factor: 150 x 140 x 86 mm fits most mid-tower and full-tower cases. Check clearance for small form factor builds. Connectors include: 24-pin ATX, two 8-pin CPU EPS, one 12VHPWR (600W capable), plus multiple SATA and peripheral cables. Works with any modern motherboard (ATX, micro-ATX, Mini-ITX) as long as the case supports ATX PSU mounting. No special memory or storage compatibility concerns, but ensure adequate airflow when pairing with high-TDP GPUs.

Product Info

The model PS1241 (PS-TPD-1000FNFAGJ-4) has been available since late 2022, retailing around 24,000 JPY (~$170 USD) in Japan. It carries 80PLUS GOLD efficiency (up to 90%+), Japanese capacitors for durability, and Smart Zero Fan for silent idle operation. Positioned as a mid-high tier PSU, it strikes a strong balance between future-proof ATX 3.0 features, build quality, and price. The 10-year warranty underlines Thermaltake's confidence in this product.

Best Use Cases

High-end gaming PCs with RTX 4080/4090 or RX 7900 XTX: the native 12VHPWR port simplifies cable management and ensures reliable power delivery. Creative workstations handling video editing or 3D rendering: the 1000W capacity and efficient operation keep the system stable under prolonged load. * Users who plan to keep their PSU for 5+ years: the 10-year warranty and Japanese capacitors promise long service life. ## Alternatives
Direct competitors include the Seasonic FOCUS GX-1000 (80PLUS GOLD, ATX 2.x, no 12VHPWR) and Corsair RM1000e (80PLUS GOLD, ATX 3.0, 7-year warranty). Seasonic's unit lacks the native 12VHPWR cable, requiring an adapter for RTX 40-series cards. Corsair offers similar ATX 3.0 compliance but with a shorter warranty and potentially lower-grade capacitors. The Thermaltake GF3 1000W edges ahead with its 10-year warranty and Japanese capacitor build.

Things to Consider

Single 12VHPWR port means multi-GPU setups are not supported — but single-GPU builds are the norm. 1000W is overkill for mid-range builds (e.g., Core i5 + RTX 4060). A 650W–750W unit would be more cost-effective. * Cables are sleeved but not individually braided, so careful routing is advised in compact cases.
