data center and psu help

[echy]

lets say i have a datacenter with each having their own psu,motherboards, cpus, etc....

how will i plug each power cable(to power up the computer) from my power outlet(on my wall) to each psu? 

will a 6 outlet power extension help? 

will it cause a power outage if i plug all power cables to my 6 outlet power extension then to my psu's? 

How are datacenters like Facebook and google powered because I don"t think they use outlet extensions.  thx

big data centers use special high-amp outlet extensions, those usually have the outlets you can see in the picture, the 'reversed' version of the power input of a computer.

 

if you don't have a lot of other thing connected to the same power group, it might work, you can, if you really want, let someone install a new power connection, only for the servers

if you have a datacenter? if you have a datacenter you dont ask this question

 

the slight stab aside, here's what they do:

 

- each server has 2 power supplies, for redundancy

- these get plugged into seperate "PDU's" (power distribution unit) which are arranged in pairs in the racks (either mounted in the rack itself, or to the side along with cable management space) to put the 2 power supplies in seperate grids.

- these PDU's have cables going out the rack, to a serverroom-wide high current implementation, usually one "cable" (not always in the form of an actual cable) per row of racks, with a 3-phase power grid across which the PDU's are spread, again with an A and B side to split up the power supplies for redundancy

- these come together to a central point where they get plugged into a UPS system (usually one for the A and one for the B side) which in turn also have generators to take over if necessary.

 

as for how you do it at home.. you check how much power your servers use, you check how much power your outlets can provide (depends on region), and you spread them out as necessary. although if you're at a point at home where you need more than one breaker for your servers.. rent rackspace.

They use dual or triple redundant power inputs from different companies and different locations.

They have PDUs (Power Distribution Units) which @marten.aap2.0 showed that plug up to rails in the ceiling and will power everything off multiple phases of circuits as well.
