Will Xeon E5-2687W work in Precision T5600

I have been offered 2 E5-2687w processors but I am wondering if the T5600 can use them, according to wiki they do support them and go as far as E5-2690.

Server (Xeon E5-16xx/26xx)

 

29/12/2018 LGA 2011 - Wikipedia

would I need a larger power supply or would the 635W be able to handle it?

 

Thank you.

According to Intel, the E5-2687 is 150W.  Your PSU should have an easy time with 2 of them, as CPU's draw the most power.

I think you'll be happy to know your T5600 takes the E5-2600 family of processors up to 8 cores.

Hi there. The default 635w PSU should be fine for dual E5-2687w provided that you’re not using any other PCIe cards with heavy power consumption. Here's my experience to share.

 

I upgraded my T5600 CPUs from 2x E5-2650 v1 to 2x E5-2687w v1, and everything’s fine with the 635w PSU. But then when I tried to install a RTX 2070 GPU and a NVMe adapter on it, the system go unstable, for example it auto-reboot whenever I run a GPU benchmark tool. After replacing a 825w PSU, it turns darkness to light!

Hi @bmcowboy,

I think you meant to say you "installed" and not "replaced" the 825w PSU?

Hi Bradthetechnut,

 

Sorry for my poor English. I mean replacing the existing 635w PSU with a 825w one.

No need to be sorry.  Just wanted make sure it was clear which PSU was being used.

Hello!

And when you installed the 150W cpu-s, there where no error message?

Message on boot, that the power supply is not enough?

Thanks.

Hopefully @HughHill answers your above post.  Meanwhile, there shouldn't be an error message.  From the owner'manual, "Your current power supply does not support the recent configuration changes made to your system. Please contact Dell Technical support team to learn about upgrading to a higher wattage power supply."

Yet, neither the T5600 Spec Sheet nor the Owner's Manual state having to upgrade to the 820w PSU to run that CPU.  May be @bmcowboy can shed some light as he has answers in this thread also?

Some troubleshooting involves - Does your unit still run with the previous CPU installed?  Make sure there's no bent pins on the CPU you're installing.  (I don't know if you bought yours new, refurb, or used.)  Re-seat the CPU.

Hi @Dellcs ,

No, it didn't prompt any error message when I ran dual E5-2687W with the original 635w PSU. Thought I do found previous post with user claimed 835w PSU is required for those 150w CPUs. Not sure why there's a difference here. Anyway, you may need a PSU with higher output when same problem happened on your workstation.
