Seasonic PRIME TX-700 (700W) 80 Plus Titanium, Fully Modular

Seasonic PRIME TX-700 is a high-class ATX power supply with 700W power and 80+ Titanium certification, aimed at serious gaming and workstation configurations. Fully modular design, black casing, and completely fanless operation make it suitable for quiet and clean builds. The active PFC and wide input range of 100 – 240 VAC ensure stable operation under various network conditions. This is a PSU that can easily handle modern graphics cards and plenty of storage without making noise.

What you get

With real 700W and output lines DC 3.3/5/±12 V, you have enough reserve for a powerful CPU and serious GPU in one system. The available 12VHPWR (12+4) Pin connector meets the requirements of modern graphics cards without the need for adapters. With 4 x PCI-Express 6+2-pin, you can power an older or additional GPU, as well as power-hungry capture/expansion cards. 8 x SATA and 5 x Molex allow for multiple SSD/HDDs, fan hubs, and peripherals in larger cases. The fanless design means complete silence under load – important if you are aiming for a quiet or completely passive configuration.

• Power 700W – sufficient for a strong gaming or creator build with a powerful CPU and high-end GPU, with good reserve for future upgrades.
• 80+ Titanium certification and efficiency up to 90% – less loss as heat and lower energy consumption under prolonged load.
• Fully modular PSU – you connect only the necessary cables, which simplifies cable management and improves airflow.
• Fanless cooling – zero noise from the power supply itself, ideal for silent, HTPC, or audio configurations.
• 1 x 12VHPWR (12+4) Pin + 4 x PCI-Express 6+2-pin – ready for modern and older GPUs, without compromising on power supply.
• 8 x SATA and 5 x Molex connectors – enough connections for many drives, fans, controllers, and accessories.
• ATX format, dimensions 170 x 150 x 86 mm – standard compatibility with most mid and full tower cases, with specified length 170 mm for more precise planning.

Who it is suitable for

This power supply is for builders who want a quiet, efficient, and reliable foundation for a high-end or well-balanced gaming/creator PC. It is especially suitable if you are aiming for an almost silent build with a modern graphics card and plenty of storage. It is not the most logical choice for completely budget systems where price is above all.

The combination of 80+ Titanium efficiency, fully modular design, and fanless operation makes Seasonic PRIME TX-700 a very strong choice if you want a PSU that you can forget about – it just works quietly and stably for years.
