400W TFX PSU for compact desktops

This 400W TFX power supply replaces the original GW-TFX200AHD and GW-T200SPWC-TFX units found in small form factor desktops. It raises the continuous output from the stock 200W to 400W, supporting hardware upgrades such as a discrete graphics card. The unit matches the factory wiring layout with an exclusive 12Pin motherboard connector and a 4Pin CPU connector.

Verify 12Pin motherboard and 4Pin CPU connectors

Before ordering, confirm that your motherboard uses the proprietary 12Pin main power connector and a 4Pin CPU power header. Standard 24Pin ATX or 8Pin EPS connectors will not fit this replacement unit. Ensure the chassis accepts the standard compact TFX form factor without modification. The wide 110-240V universal input works on any mains supply.

Sustained 400W with full protection circuits

Under sustained load the unit delivers its rated 400W continuously rather than only in short bursts. Active PFC maintains high power efficiency across the 110-240V input range. Built-in OVP, OCP and SCP circuit protection guards components during extended office work or light gaming sessions, preventing shutdowns or damage from voltage spikes or short circuits.

Questions about this item

Does the unit ship with the 12-pin motherboard connector and 4-pin CPU cable already attached, or must I source them separately?

The replacement PSU includes the exclusive 12Pin motherboard connector and 4Pin CPU port pre-wired to match the original GW-TFX200AHD layout, so no extra cables are needed.

Should I keep the original 200W unit or switch to this 400W model for a graphics-card upgrade?

The 400W continuous rating doubles the stock 200W capacity, providing headroom for a discrete GPU and other upgrades while still fitting the same TFX chassis.

Will the 400W rating hold up when the supply is running at 110V mains instead of 240V?

The unit accepts a universal 110-240V input with active PFC, so the full 400W output is available across the entire voltage range.
