CPU Overclock safe?
CPU Overclock safe?
Hello there. I’m checking if a slight overclock of my i5-4690k could harm my system. I recently damaged the same motherboard and GPU by using an oversized power supply, so I want to be cautious. CPU temperatures hit about 60°C during heavy use without overclocking.
I can assure you that's not the typical method used to achieve high performance.
A PSU doesn't simply 'push' wattage; a system 'pulls'.
You might link a 1600W power supply to a setup that uses less than 150W when fully loaded, and it would operate at full capacity, though this would not align with the typical efficiency range for a PSU (and would imply the unit isn't functioning properly).
What kind of overclocking are you doing? H81 shouldn't support multiplier adjustments... unless maybe it changed in an older BIOS version—though I wouldn't anticipate compatibility with a Devil's Canyon CPU.
In general, it mostly stays within safe limits.
I can assure you that's not the typical method used to fry a board. In a straightforward way, a PSU doesn't directly 'push' wattage; instead, a system 'pulls'. You could link a 1600W PSU to a setup drawing less than 150W at full load and it would operate at full capacity, even if it doesn't fit the standard efficiency range for that PSU (and it assumes the unit isn't faulty).

In terms of safety, voltage is the main factor. Temperatures from the CPU or VRM usually result from voltage changes. A PSU might play a role, but a 600W unit from EVGA (presumed 'White') isn't ideal and shouldn't harm components unless it's defective.
Overclocking should not lead to harm. However, pushing frequencies and voltages too high might cause issues.
On my earlier PC I ran the i5 4690k OC'd at 4.2Ghz smoothly using a 60mm Corsair AIO, and I could also achieve 4.6 though it was a bit challenging.
