A failed or mismatched PSU takes a server offline, so server power supplies need to be the exact wattage and model your chassis expects. We stock hot-swap redundant server power supplies for Dell PowerEdge, HPE ProLiant, Lenovo, and Supermicro, and verify wattage, connector, and firmware fit before shipping. Replacing a unit or adding redundancy? Send us your server model and we'll confirm the right part number. Every PSU is tested and backed by a 3-Year Warranty.

A server running on one of two power supplies is a server one fault from an outage — which is why PSUs are our most time-critical part category. We stock hot-swap power supplies for Dell PowerEdge, HPE ProLiant, Lenovo, Supermicro, and Cisco UCS platforms across wattages from 495W to 2400W, shipping same day on in-stock units.
Matching is precise: wattage, efficiency rating, and connector format must align with your chassis, and mixed-wattage pairs are generally unsupported. The part number on the failed unit's label is the fastest identifier; the server service tag works as well. Every PSU is load-tested before dispatch.
Yes — that is the normal repair. The replacement must match the remaining unit’s wattage and part family; we will confirm the match from your part number or service tag.
Yes. Redundant server PSUs are designed for replacement with the system running — slide the failed unit out and the new one in without downtime.
Read the label on the existing unit — the part number there is definitive. No access? The server model plus configured wattage narrows it, and we will verify before shipping.
