Question for power requirement of PowerEdge R740

Hi, 

I hope you have a great day.

I'm considering purchasing PowerEdge R740 (PSU: 750W AC, Platinum).

120VAC 3-phase power is available.

Is there any problem even if 3-phase power is supplied to R740 instead of single phase?


Best regards,

I'm not an electrician and I can just check the specs that we have here, but I would say you're good to go.

Stefan, 

First of all, thank you for your reply.

I've already searched the datasheet and I couldn't confirm it. That's why the question was posted on the community site.

I believe this site has an obligation to provide information to customers.

Could you please give me accurate information about phase?

While Dell PDU's support the use of 3 phase power, I don't believe the servers support it directly. If you give me the part number for the power supplies I can check to be certain if they do or not.

 

 

 

Let me know.

Those are the specs of the power supply, do you know the part # that is listed on it?

 

Also, if it is the power supply that came with the unit, you can Private Message the svc tag and I can verify that way as well.

I have plan to purchase PowerEdge R740. That's why i don't know part #.

I would like to purchase R740 with the aforementioned power supply. Please let me know the availability of 120VAC 3-Phase power. The purchase will be decided by information you provided.

 

Best regards,

Hello,


I was able to find that there was Dell Power Distribution Units 3-phase support, but I could not access such information to confirm this on the server specific. Just a note caught my attention at the link below: "NOTE: This system is also designed to connect to the IT power systems with a phase to phase voltage not exceeding 240 V."

I don't want to share any wrong information. It may be helpful to get more accurate information by contacting sales.
