What this unit does

This 200 W ATX power supply is built as a direct replacement for the Great Wall GW-XSP200WV45B. It delivers a 4.5 V rail rated at 40 A alongside standard ATX outputs for compatible systems.

Who it suits and who it does not

It fits owners of the exact Great Wall model who need a new, 80 PLUS Gold certified unit with Modern Standby support and a zero-RPM fan mode for silent low-load operation. Builders working on any other chassis or motherboard should look elsewhere because the fixed 4.5 V / 40 A specification will not match different voltage or current requirements.

The specification that decides fit

The 4.5 V, 40 A output rating is the single figure that determines whether this supply will power the target board correctly; if the original label does not show that exact rail, the unit is not compatible.

Questions about this item

What cables or connectors come with this KHACHIMO 200W unit and what must I source separately?

The supply is sold as the PSU module only; you will need to provide your own ATX power cables and any motherboard or peripheral connectors required by your build.

The title lists 4.5 V 40 A — is that the only rail or are there other voltage options?

The 4.5 V rail rated at 40 A delivers the full 200 W; no additional rails or capacity variants are offered for this model.

How does the 80 PLUS Gold rating affect daily use of this 200W supply?

Gold certification means higher efficiency across typical loads, so the unit draws less wall power, runs cooler and allows the fan to stay off longer under light demand.
