500W 1U server power supply

The OIAGLH PS-4501-1ZT delivers 500 W in a 1U form factor suited to ITX and FLEX chassis. It targets builders assembling compact servers or workstations where rack height is constrained. The switching design fits the K39 platform without exceeding the single rack unit allowance. Buyers needing redundant or hot-swap modules should look elsewhere.

Sustained load behaviour

Under continuous demand the unit maintains its rated 500 W output within the 1U enclosure. Thermal management relies on the integrated cooling solution matched to the 39 mm height constraint. Extended operation at full power is supported by the switching topology without derating. Systems requiring higher peak headroom or auxiliary connectors beyond the standard set are not addressed by this model.

Questions about this item

How loud does the PS-4501-1ZT get when it runs continuously in a 1U server?

The 1U form factor typically uses a small high-speed fan, so expect noticeable airflow noise under sustained 500 W load.

Which motherboard power connectors must my ITX board already have for this PS-4501-1ZT to work?

It provides standard ATX 24-pin and 4-pin CPU power cables; your board needs matching sockets.
