Will a 1080 Ti, 7700k and two 3.5" HDD's require a PSU upgrade?

[DELTAprime]

For the system in my sig I'm about to replace the 6600k and dual 2.5" HDDs with a 7700k and dual 4tb 3.5" HDD's from either Seagate or WD. I'm also considering selling my GTX 1080 and getting a AIB GTX 1080 Ti. Would these three changes be enough to require a PSU upgrade or is there still enough headroom with my 600w PSU for these components?

http://www.coolermaster.com/power-supply-calculator/ use this to check the wattage you need for your system.

nvidia recommends a 600 watt psu with an i7 clocked at 3.2 ghz. so my guess is that if your psu is 650 watt or higher its fine.

Linus didn't get close to 600, so I would say you're safe:

Yeah I saw that but there's a difference between a high load and peak load. Not sure if Crysis 3 can be used as a peak load metric.

A i7 7700K and a GTX 1080Ti, even when overclocked heavily and running something like Furmark, should be able to run on a decent 600W power supply unit. You'll be fine.

The SF600 you have is fine.

True, however the test method he used did max out the gpu. Your cpu has a tdp of 98w (if I recall correct), and hdd, fans, and so on won't make a huge difference. But I think ppl have gotten to the consensus that your current psu if just fine

My friends computer pulls 380-440watts under load with his i7-6700k @ 4.6ghz, FE 1080@2100, 32gbs of ram, 3 SSD's, with a full custom waterloop during gaming sessions. You should be fine OP.
