Server Power Supply
How many Amps does a server with 500W PSU draw?
I need to know how many Amps a server with a 500W power supply would draw. I know that Current = Amps/Voltage, but is the 500W correct to use in this case? It seems quite high - would work out to be just over 2A, which would mean that a rack of 42 x 1U servers would draw over 80A, which is more than most racks have power for.
The issue may be that most servers dont draw anything like the max power wattage of their PSU - ie the PSU can supply a max of 500W of power, but under normal usage, it doesn't. If that is the case does anyone know a more average figure? I'm using an HP DL130 G3, 2.6GHz with 2GB RAM and 2 x 80GB S-ATA discs and its that server that I need to know the actual power consumption for.
Thanks
When you're spec'ing out power for servers, you need to make sure you use the proper ratings. Although you are correct that the PSU will not draw 500W all the time, it is theoretically possible that every server in the rack will draw its maximum power at the same time. Underpowering a rack has very bad consequences (breakers flipping and servers powering down).
Besides, I have never seen a Server Rack with 42 separate servers in it - that is a heck of a lot. Normally many of the slots are dedicated for keyboards and monitors, you'll have 3U RAIDs, etc.
