Power Equipment
Power Equipment covers what keeps servers, switches and laptops running. The largest share is replacement power supplies for servers, storage arrays and network switches, from 250W hot-plug units to 2800W supplies for large chassis. Alongside them are UPS systems from APC, Liebert, CyberPower and Tripp Lite, rack PDUs from APC, Eaton, HPE and IBM, controller and UPS batteries, laptop and device adapters, power banks and surge protectors.

Buying guide
Planning power for a rack
Start from the real load
Measure or estimate what the equipment actually draws, then size supplies, UPS units and PDU circuits with headroom above that figure.
Circuits and plugs
Higher-capacity supplies, UPS units and PDUs often need 200–240V circuits and locking or IEC plugs such as NEMA L6-30P or C20, so check the outlets in the room first.
Real redundancy
Dual power supplies only protect against an outage when each one is fed from a separate PDU and circuit, ideally with its own UPS.

Frequently asked questions
What's the difference between VA and watts?
Watts are the real power equipment draws; VA (volt-amperes) is apparent power, which also counts current that does no useful work. The ratio between them is the power factor, so a UPS rated 1500VA/900W can carry at most 900W of equipment.
Can I use a higher-wattage power supply than the original?
In servers, usually, as long as it's a supported option for that model and both supplies in a redundant pair match. The server draws only what it needs, so the larger supply simply adds headroom.
Do you carry power parts for legacy systems?
Yes. Supplies for HP 9000 V-Class servers, DC power converters for StorageWorks tape libraries and AlphaServer auxiliary power modules are listed beside current parts.
