PSU Headroom for Overclocking?
PSU Headroom for Overclocking?
The question has been discussed multiple times, yet I remain uncertain due to the variety of responses. PCPP suggests a maximum of 400W, but should a 550W PSU provide enough headroom for an i5-7600k? I plan not to overclock the EVGA FTW 1080 since it's already running high and adding more heat isn't beneficial in a mini ITX case.
550w is more than enough. The maximum the CPU will use at stock settings might only be a few extra watts, but an OC could push it up to around 30 watts. A GTX 1080 can sometimes jump in power, so choosing a PSU with a bit more capacity is your safest choice.
550w is more than enough. The maximum the CPU uses at stock settings might only be a bit higher, around 30 watts. Since the GTX 1080 can sometimes increase its power draw, choosing a 550w power supply gives you the necessary buffer during overclocking.
