On Kijiji I spotted a good offer for an HP Pavillion Gaming Desktop (690-0xxx). I'm unsure of the exact model number but know it's an i7-9400 processor. I need to check compatibility for upgrading the CPU and have a 2TB HDD, 8GB DDR4 RAM, and a GTX 1660Ti GPU. What socket should I focus on for the CPU upgrade?
The 8th and 9th generation models fit the LGA 1151 v2 socket. More important than the socket itself is the BIOS settings set by the manufacturer. Visit HP's website for this specific PC and check the approved CPUs there. An i7-8700 or 9700 should likely work, but confirm first before purchasing. You could use CPU-Z to determine the exact motherboard model and look up compatible options.
It's the i5 9400 you're having, not the i7-9400. Focus on the CPU cooler and motherboard VRM design first. The i9 wouldn't be a big upgrade unless it handles minimal power draw. I suggest getting it because the components are worth over 540 CAD, but don't plan anything until you own it.
