Server Power Supply 350W

The TOPOWER TOP-350W1U-PFC is a 350W ATX12V and EPS12V unit built for single-server deployments. It fits 1U chassis where a compact footprint is required. The supply targets integrators maintaining legacy platforms or industrial PCs that demand standard voltage rails. It is not suited for builders who need redundant power modules.

Sliding Connectors Gray Iron Case

A gray iron enclosure houses two 40mm fans governed by thermally controlled Silent Control Technology. The main power interface uses sliding connectors that accept both 20 or 24 pin and 4 or 8 pin motherboard headers. This mechanical flexibility reduces cable strain during repeated service cycles. Input range spans 100 to 240 V for global rack compatibility.

Protection Circuits No Bundled Software

Over-voltage, over-current and short-circuit protection circuits guard every output rail including +3.3V, +5V, +12V, -12V and +5VSB. Low ripple and noise characteristics support sensitive industrial workloads. No software utilities or mounting accessories are included in the package. Buyers who expect modular cable sets or monitoring applications must source them separately.

Questions about this item

Does the ATX12V / EPS12V standard cap the +12 V rail at 24 A?

Yes, the +12 V rail is rated at 24 A within the ATX12V / EPS12V specification.

Will the 200 mm depth fit a standard 1U rack chassis?

The unit measures 200 x 100 x 40 mm, matching the depth budget of most 1U server enclosures.

How do the sliding 20+4 pin and 4/8 pin connectors attach to the motherboard?

Align each sliding block with the socket, press straight in until the latch clicks, then route cables clear of the twin 40 mm fans.
