  • +5 VSB provides 2 A to keep management controllers alive

Industrial 300 W ATX server supply

This WMtec DPS-300AB-70A unit delivers 300 W of regulated power for rack-mount and tower servers that require standard ATX output rails. It accepts a wide 115-230 V input range at 50-60 Hz, making it suitable for data-centre and industrial deployments worldwide. Builders maintaining legacy platforms or replacing failed modules in 1 U and 2 U chassis will find the form factor a direct fit.

Sustained-load rail stability

Under continuous operation the +12 V rail supplies 15 A while the +5 V and +3.3 V rails provide 30 A and 28 A respectively, with minor rails at 0.3 A on -5 V, 0.8 A on -12 V and 2 A on +5 VSB. The supply maintains these combined outputs without the voltage droop seen in short-burst ratings, ensuring reliable delivery to multiple drive back-planes and CPU sockets over extended duty cycles.

Questions about this item

How much heat and noise should I expect when the FSP300-60ATV runs continuously at 300 W?

The 300 W unit draws up to 10 A at 115 V or 5 A at 230 V, so sustained full-load operation will produce noticeable heat and fan noise typical of a 300 W server PSU.

Which cables or connectors must I already have to install this PSU in an ATX chassis?

You need a standard ATX 24-pin motherboard connector, a 4-pin or 8-pin CPU power cable, and peripheral connectors for +3.3 V 28 A, +5 V 30 A, +12 V 15 A, -12 V 0.8 A and +5 VSB 2 A rails.
