Optiflex 990 MT with Core i5 2500 CPU Upgrade

Question

Hi there,

I have an Optiflex 990 (Mid Tower) with an i5 2500 CPU that I would like to upgrade. A few questions:

1. Can I upgrade the CPU to an i7 2600?

2. Can I add more RAM and what is the maximum. According to DELL ,the maximum is 16GB but I have read many forum threads saying 32Gb will also work...

3. I would also like to change the disk for a SSD (1 Tb). Will it be supported? And which brand do you recommend?

Thanks for your help,

Christian Dubuc

As for an SSD, yes, a 1TB will work in it.  Go with a name brand vs. cheapy brand.  Crucial, PNY, and WD (Western Digital) are good brands just to name 3.  I hear Kingston doesn't come recommended for their SSD's.

' K ' CPU's use over 95W S CPUS are 65W whereas the 'T' cpus use 45W. All 790 990 units have LESS THAN 300W power supply. 95W cpu needs optional 365W power supply minimum.  65W is marginal I would not risk damage. 2600S is 65W https://ark.intel.com/content/www/us/en/ark/products/52215/intel-core-i7-2600s-processor-8m-cache-up-to-3-80-ghz.html 2600K is not a good idea unless you upgrade cooling solution to copper and power supply.
