Look at this link for my PC parts. How much power do I really need if I want to overheat my CPU and GPU just enough to feel it?

to go with power supplies, don't just look at watts; check the total amp rating on the 12v line. As shown by the mods... getting too close to the max load can make things get hotter and louder. In real life, if you can push a unit to about fifty percent, that's the sweet spot for most stuff. A 750-watt system should be fine for now. If your plan includes an SSD stick, go with an M.2 drive just for speed. Faster read speeds help gaming load times way more than anything else. For RAM, aim for 3200 or 3600 stock speed at 1.25 volts. Some older 3000-series sticks need higher voltage to run at their rated overclocked speeds. Don't buy a new GPU yet until you get more info from Nvidia first.

I'm going to buy an EVGA G3 750-watt power supply. It will definitely handle the load, and I can even push it past its limits if I want to overclock my system.

A 550-watt power supply is fine. You should look at a good brand like Seasonic, EVGA or Corsair and pick one marked "gold". I think a 750-watt unit is too much for what you need, so stick with the smaller size.

You need a good power supply, like the 7664 model. A solid one from Seasonic, EVGA, or Corsair would work great. You can probably skip buying the extra wattage and just get one that fits your needs. Also check out this link for more info on Intel CPUs. Not when you're trying to make an 8700k run faster than stock settings with a GTX 1080 card. These chips eat up a lot of power if you push them too hard.

Okay... yeah. What do you mean by "OC power consumption" on that LINK in TH review? So, at 550 watts, that's totally fine and enough for what we need. I don't think anything over there is really necessary unless someone has a real reason to push for more than that.

The system is already rated for 409 watts. Before overclocking, that was about 74% of its full potential. When I tried to run it close to capacity while overclocking, the seasonic gold 650w even PSU died a premature death. The graphics card in question, which was a 780ti back then, used more power than even a 290x would have needed.

To get power, you don't just look at how much wattage the thing has, but at the total amp rating on the 12v line. The mod said this earlier too. If your power supply is really close to its max load, it will get hot and loud. In a real world situation, if you can run a unit at 50 percent, that's still considered good luck for the golden zone of a power supply. As posted by someone named 'mod', a 750w unit will work fine. If you're thinking about a slatter on go with an 850w unit, sure, but only if your build allows it. On your build side, if you can afford to spend a little extra money for an m2 drive, that'll help speed things up. When you game, faster read speeds will make load times feel better. For the ram, check out 3200/3600 stock speed at 1.25v. Some older rams with 3000 and higher speeds need more voltage to run at their rated overclocked speed. Don't buy a gpu yet until you have more info on the nvidia's next gpu drop coming in a few weeks.

Sorry to reply to such an old post, but I am having a similar problem with overclocking. My computer keeps shutting down and then restarting when I play games or run the OCCT power test. I have a 650W power supply unit. Does this look like it might be because I don't have enough wattage? My estimated wattage before I overclocked was 474 watts.
