Is it safe to use a UPS designed for desktop PCs to power a server

electrical-powerhp-proliantups

I am working on a server within my office. The server will eventually be relocated to a data center. I would like to be able to leave the server switched on in my office, which means I would like to be able to protect it from power outages or surges. In the office I only have desktop UPSs. I would like to avoid forking out for an expensive server class UPS.

I don't mind if it only has protection for a short time (Even a few minutes would be longer than any likely power drop where I live)

The UPS is APC Back-UPS ES 400 (400 VA, 240 Watts)

The server is DL 360p Gen 8 (750 watt PSUs)

I would not plug a server with a power supply capable of drawing 750 watts into a UPS which is only rated at 240.

The issue isn't really that it's a "server" or "desktop" UPS. You're likely to trigger overload protection and drop your server even if the power input is fine.
