Tyan KGT14M1-040S3F4 Rack-Mountable ATX Server Chassis

The Tyan KGT14M1-040S3F4 is a rack-mountable ATX server chassis built around a 400 watt power supply, sized for integrators who need a defined physical envelope before committing rack units in a cabinet design. At 9.80 x 20.40 x 23.90 in (L x W x H) and 20.20 lb, it's a known quantity for elevation drawings and shipping calculations before the build ever leaves the bench.

Key Features

• ATX form factor: Accepts standard ATX motherboards and power supply mounting, so board selection isn't locked to a proprietary chassis spec — useful when standardizing spare-parts inventory across a fleet of servers.
• 400W power supply: Sized for a single-socket build with modest expansion card and drive count rather than a dense GPU or multi-drive configuration — confirm total system draw against this ceiling before populating the chassis.
• 2x USB 2.0 ports: Front or rear-accessible USB 2.0 for keyboard, mouse, or USB media during initial provisioning and firmware updates — adequate for setup and diagnostics, not high-throughput peripheral use.
• Rack-mountable design: Built for standard rack integration rather than tower deployment, which matters when the target environment is a data closet or server room with fixed rail spacing.
• 20.20 lb chassis weight: Light enough for single-technician handling during rack installation without a lift-assist, a real consideration when racking gear solo after hours.

Integration & Compatibility

The KGT14M1-040S3F4 (often searched as KGT14M1 040S3F4) pairs with ATX-compliant Tyan motherboards for builds that need a defined, quotable chassis and PSU baseline rather than a custom fabrication. Confirm motherboard I/O shield and drive bay count against your specific board before finalizing a bill of materials — check the server chassis and components catalog for compatible boards and expansion accessories, and review a power planning guide if the deployment sits alongside PoE infrastructure in the same rack.

The KGT14M1-040S3F4 crosses my desk most often as the chassis line item on a quote where the motherboard is already picked and someone just needs a rack-mountable ATX enclosure with a power budget that matches the build.

Technical Highlights:

• 400W power supply: Enough headroom for a single-CPU ATX build with a handful of drives, but don't plan a multi-GPU or high-drive-count config around this number without checking total draw first.
• 9.80 x 20.40 x 23.90 in footprint: Confirm rail depth and rack unit height against this before ordering — a 23.90 in depth is worth double-checking against shorter cabinets.
• 2x USB 2.0: Fine for provisioning and console access; if the deployment needs faster external storage transfer, plan for a USB 3.0 card or onboard header instead.

Deployment Considerations:

• At 20.20 lb, this is a one-person rack install, but confirm rail kit compatibility separately since chassis dimensions alone don't guarantee rail fit in every cabinet brand.
• The PSU wattage is the hard ceiling for the build — size drives and expansion cards to stay under 400W before finalizing the parts list.

Reach for the KGT14M1-040S3F4 when the project calls for a standard rack-mount ATX chassis with a fixed, quotable power budget — not for GPU-dense or high-drive-count builds that will outgrow 400W fast.
