Xeon E5462 in a Dell Optiplex 780

[yassinmaroshi]

Will it work with a Dell Optiplex 780?

CPU that I want to buy:
Xeon E5452, 2.8 GHZ 12 MB cache

you can check Dell's website for compatible CPUs with a given Dell model....

Arm yourself with all serial/model number/revision number info ahead of time...
However, I see no Xeons listed as compatible in preliminary searches of your model number...

The Optiplex 780 chipset doesn't support LGA771 Xeons, only X3xxx, or L3xxx LGA775 CPUs. <95W also.
Here's a list of quad core CPUs filtered for that system.

X3360 is the best Xeon that will officially work, someone has claimed a X3362 works; the E5 series doesnt work.

Problems, you dont say what form factor, Dell do this model in everything from Tower to USFF.

That advice is based on the chipset, Dell are notorious for locking down the BIOS in their SFF & USFF PCs, so it MAY not have the microcode to allow the motherboard to recognise the Xeon.

Assuming SSF/USFF.

Next issue is power draw, can the Dell psu supply enough juice.

Final issue is heat; the fans Dell fit are noisy and dont push much air, but if you dont use fans with a very close rpm match, the BIOS may shut down ALL the fans and fry your new CPU (happened to me with a Dell USFF).

The Dell PSU can power anything the motherboard will support, and there are cooling solutions for all sizes.
