I want to upgrade my CPU from i5 to i7

[Mamma_S]

I have this motherboard: HP Desktop PCs - motherboard specifications, Tampa2 | HP® Customer Support

I have this CPU:    Intel Core i5-8400

I want to upgrade it to the i7. The HP automated support suggests this:

Intel Core i7-8700K (Coffeelake) 3.7 GHz, 6 Cores 95 W

                                         OR

Intel Core i7-8700 (Coffeelake) 3.7 GHz, 6 Cores 65 W

I cannot locate the bottom one in the list that runs at 3.7Ghz .I can find one that runs at 3.2Ghz. Will  that be OK to use?

Or should I go for the top one in the list which is 95W (30W more than my current CPU)?

If so, how do I know if my PSU will handle it? 

Intel Core i7-8700 3.2 GHz 6-Core Processor vs. Intel Core i7-8700K 3.7 GHz 6-Core Processor - PCPar...

Any help would be appreciated.

Hello

if I am not mistaken you have a 500w power supply
your computer is this one:

i find this model, with 500w power supply (same motherboard) and an I7

OMEN by HP 880-100nq Desktop PC Product Specifications

Intel Core i7-8700K

500 W internal power supply

that should be fine!

[edit]

the model you found is probably correct
