The best CPU you can install on a Dell 0PGKWF motherboard is Intel’s 2nd Gen Core i7-2700K (Sandy Bridge) processor. The 0PGKWF motherboard is used in OptiPlex 990 Ultra Small Form Factor. According to the spec sheet, 990 USFF is using Q67 chipset and supports only 2nd Generation Intel Core i7, i5, i3 processors.
Keep in mind that if you are using the 0PGKWF motherboard inside a Dell 990 USFF desktop, there is only 200 watts power supply on that machine, and 200 watts are not enough for 95 watt CPU. So, to follow the actual Dell spec, if you use OptiPlex 990 USFF with 200 watts PSU, you have to to use Core i7 2600S.
As a general guideline, a basic system with a 95 watt CPU, a single storage drive, and an integrated or a low-end graphics card will typically require a ~300-watt PSU.
Other worthy CPUs you can use with this model are Core i5 2500 and 2500K.
