Product Identity

The Taifast S700 is a 700 W ATX power supply built with all Japanese capacitors and a single fan. It delivers 700 watts of continuous power through a non-modular cable set. Active PFC achieves a conversion rate above 85 percent. The unit is new and intended for standard desktop builds.

Suitability

This unit suits builders assembling a mid-range system that requires a straightforward 700 W ATX source with fixed cables. It is not for builds that demand fully modular cabling, higher efficiency certifications, or multiple fans for specialised cooling layouts. Buyers needing those features should look elsewhere.

Bundled Impact

The fixed cable harness simplifies inventory but limits routing flexibility in compact cases. All Japanese capacitors contribute to long-term stability under load. The high-speed silent fan aims to extend operational life while keeping noise low. Active PFC above 85 percent reduces reactive power draw from the mains.

Questions about this item

What type of motherboard power connector does this 700 W ATX unit need to function?

It uses the standard ATX form factor, so it connects to any motherboard with a matching 24-pin main power socket and the required CPU auxiliary plug.

Can the single non-modular fan and fixed cable set fit inside an older chassis with limited cable routing space?

The unit has one fan and a fixed cable bundle; it will install in any ATX-compatible case, but tight routing channels may make the non-removable cables harder to manage.

How can I verify the active PFC is delivering the stated 85 % conversion rate once the system is running?

You can measure input and output power with a calibrated meter under load; the supplier rates the active PFC conversion above 85 % at full 700 W output.
