XPS 8940, CPU swap from i7 65w to i9 125 watts?
XPS 8940
Can the I9-10900KF (125W) replace an I7-10700(65W) on Motherboard 0KV3RP?
I am investigating whether I can upgrade my 8940 currently with an I7-10700 (65w) Comet Lake (LGA1200) with a I9-10900KF (125W) on the Dell motherboard (0KV3RP). My system has the upgraded Dell CPU Cooler with 125 Watts, the G5 5090 5000 Optiplex CPU Cooler Fan With Heatsink VWD01 (which Dell advertised but didn't sell with the 8940, opting instead to ship with the standard pancake heatsink), and a 500 W rated power supply. I have the DELL GeForce RTX 2060 SUPER which has a TDP of 175 W.
I believe I have the boxes ticked off for power (I would like more, but it is unclear if I can upgrade that in the 8940) and advanced heatsink for the CPU already, but I am concerned about whether the motherboard (0KV3RP) Chipset and Bios (2.22.0) can work with the higher base wattage CPU?
Is it possible to drop the I9-10900KF 125 CPU into the 8940?

Re: I am concerned about whether the motherboard (0KV3RP) Chipset and Bios (2.22.0) can work with the higher base wattage CPU
no worries. as long as it is a 10th gen cpu, your motherboard would be able to support it. of course you need to be very careful not to bend any cpu socket pin when swapping cpu, which is always a risk depending on your skill and experience.
your 500w psu is good enough in that regard for 125w cpu. for -k and -kf cpu you should consider upgrading VRM heatsink.
the community consensus is that your motherboard DP/N KV3RP only works with 10th gen cpu. It does not support 11th gen due to chipset limitations

Based on the Cooler and PSU you indicated, it should work fine.

Thanks, everyone.
I've decided to instead upgrade a system around a I7-11700 which I am pulling out of a XPS 8940. That 8940 sold with a 10th gen motherboard/chipset that doesn't work with the 11th gen CPUs ability to use PCIE 4. It was a refurbished machine, so it's unclear how many 11th gen CPUs are socketed in 10th gen motherboards on the 8940.
Regardless, I am building a new PC around that chip by getting a new generation appropriate motherboard, new high speed ram for that generation and a PCIE Gen 4 SSD; which upgrades me from PCIE Gen 3 speeds to PCIE Gen 4 speeds.
