Dell T7400 PRO workstation

What size Power Supply Backup is required? The unit has a 1000W power supply, but I cant imagine it using all that power all the time. I guess what I'm asking is what can I get away with? I don't want to kill my computer( starve it for power).

It would depend on what the configuration of the box is. If you only have one socket filled, 4GB RAM and an NVS graphics card the power load would be significantly different than if you had both sockets populated, 64GB RAM and the FX5800 graphics. Even which CPU model you have will change the power required.

1000W power supply (Dell proprietary for thsi unit.

The only thing I will be adding to the above is:
LSI Data controller in one of the PCI x 16 slots (the Board

has 2 of these slots). I will be using this data controller

to bypass the one that is native to the board, giving me more

flexibility to move on the go to a totally different system in

the event of a system failure.

I would think you need 600 to 800 W power supply. You don't have a high power graphics card or MAX memory. I don't know if that motherboard has standard power connectors.

Are you actually asking about a UPS sizing or a replacement power supply? -- Maybe I misinterpreted your request...

Sorry, maybe I didn't ask question correctly. The unit has a 1000W power supply from Dell. I need info as to what size UPS i can get away with. I bought a APC 550va/ 330W. My friend helping me with this build says not big enough. Don't know enough about this.

 

[kanewolf]

The 550VA is probably not big enough. The two CPUs could be 250W. My guess that just idling, it is probably 150W. If you have anything running, you would be exceeding the UPS. The best thing to do is measure the power usage. There are inexpensive energy monitoring meters that plug into the wall and allow you monitor the power usage. The kill-a-watt meter is one of the most common.

I would think you would want an 800VA to 1000VA to have any runtime to shutdown cleanly.

Thank you for all of your help.. Sorry it to me so long to get back to you. I was researching where to purchase this Kill A Watt in Canda. No retailer has it, so I ordered it online. I'll let you know what the machine is actually drawing.

It is a handy tool to have around. You don't use it often, but when you need it is sure is handy.

I bought 2 Kill A Watt devices. I figured once I was paying for shipping, I might as well. Anyway, before that I returned my 330W UPS and purchased a APC BX1300 Back-UPS. It will handle up to 765W, and give clean electricity to computer connected to it. It has a readout that can display the voltage, frequency etc... When I started the UPS with only the computer and monitor plugged into it- the build mentioned above, it read about 190 something Watts. Now I have the computer and my surveillance system plugged in. The unit shows a range of 240-245 V . The 1000W power supply that Dell puts in this system , must be in case I were to max it out with 128 GIG of RAM, dual SLI graffic cards plus the Dual Xeon quads cores (that come on the system), and other stuff that there is room for. I guess I was worried about nothing, but when spending large dollars on a system, better to be overprotected than under. Kanewolf thank you for your expertise, advice and your time. I learned a great deal in researching this issue.

No problem. You can thank me by picking a best solution ...
