Thermaltake PS-TPP-1000FNFAPU-1 1000 W power supply

1000 W ATX 3.1 power supply

This fully modular unit delivers 1000 W continuous output at 40 °C and meets 80 PLUS Platinum efficiency at 115 V input. It is built for builders who need a compact, high-efficiency supply that supports the latest ATX 3.1 standard and native PCIe 5.1 12V-2x6 connections for modern graphics cards. The 135 mm hydraulic bearing fan and 100 % Japanese 105 °C capacitors provide quiet operation and long-term durability under heavy loads.

Installation and common issues

The flat etched cable set is fully modular, so you connect only the leads your build requires, improving airflow and cable routing in tight cases. Dual-colour H++ connectors show a matcha indicator that disappears when the plug is fully seated, reducing the risk of loose power connections. Ensure the 12V-2x6 cable is routed without sharp bends and that the fan intake remains unobstructed; the most frequent issue is restricted airflow in smaller chassis.

Pre-order checklist

Verify that your case can accommodate a 140 mm deep power supply and that the 135 mm fan has clearance for intake air. Confirm your motherboard and graphics card require the native 12V-2x6 connector; older GPUs using traditional 8-pin PCIe plugs will need the appropriate modular cables from the set. Check that your mains supply falls within the 100-240 V, 47-63 Hz range and that the 15 A maximum input current is supported by your circuit.
