520 W ATX server supply

This 520 watt ATX power supply is built for 3Y server platforms that use the 6521B family of units. It delivers standard ATX output for rack-mount or pedestal servers needing a direct replacement. The unit is supplied new and tested working.

Check 3Y part number match

Verify that your server requires a YH-6521B, YM-6521B, YM-6521BAR or YH6521-XBAR unit before ordering. Confirm the chassis accepts a standard ATX form factor and that the existing wiring harness matches the replacement. Buyers needing a different wattage or proprietary form factor should look elsewhere.

Questions about this item

Does the 520W unit include the mounting screws and power cord, or do I need to source them separately?

The 520W unit is supplied as the power supply module only; mounting hardware and IEC power cord are not included and must be obtained separately.

Which of the listed part numbers — YH-6521B, YM-6521B, YM-6521BAR or YH6521-XBAR — should I choose for my server?

All four part numbers refer to the same 520W form-factor and connector layout; select the one that matches the label on the unit you are replacing.
