Title: suggestions of server psu 2400watt Post by: totti10it on September 03, 2017, 07:44:35 PM please i need suggestion of server psu 2400 or higher
but with voltage input range 100-240v not 200-240 if not present what is the biggest server psu with input 100-240 Title: Re: suggestions of server psu 2400watt Post by: puwaha on September 04, 2017, 04:56:50 AM please i need suggestion of server psu 2400 or higher but with voltage input range 100-240v not 200-240 if not present what is the biggest server psu with input 100-240 You are going to have a hard time finding one. Power(watts)=Volts*Amps so... 2400 watts divided by 120v would be 20 amps. Most household electrical circuits on 120v are on 15 amp breakers. You should really only use 80% of a circuit, so the maximum you should put on a 15 amp breaker would be 1440 watts at 120 volts. This is why 2400 watt PSUs will only work on 220-240V. The wiring is a much lower gauge, which means it can handle more current (amperage), and thus can handle the higher wattage. Plus 240V circuits are usually on larger breakers to accommodate the larger wattage and amperage.

As the above poster described:

It won't gain you much if you're planning to scale up, however.

DO YOU HAVE any buying links for good ones? here all the stabilizers are of low quality Title: Re: suggestions of server psu 2400watt Post by: puwaha on September 04, 2017, 05:57:29 PM please i need suggestion of server psu 2400 or higher but with voltage input range 100-240v not 200-240 if not present what is the biggest server psu with input 100-240 You are going to have a hard time finding one.

The minimum is 200V |
