Power Supply Calculator

I'm not sure you understand enough about computer power supplies in order to properly understand what those calculators are telling you.

List your components, we will tell you what you need. Also, will you OC or not?

The problem is that the PSU I already have only has ~400W continuous usage, which according to the Power Supply Calculator, will be insufficient for this build. I intend to overclock the CPU to at least 3.4 Ghz, higher if possible. Not sure if I should upgrade the PSU or just buy a GTX 960, which uses less power.

They're all bullshit and massively overestimate what you need. My entire system draws 150w at full load, this calculator thinks it uses 300 and recommends a 500w PSU.

Just do some actual research on what your components really need.

Your current PSU is fine.

Gonna need a nuclear reactor to power that

24/7 running at 405 W load means how much would that cost on electricity?

So which is it?

Most PSUs have the highest efficiency at around 50-60% load.

Let's ask the real question everyone is wondering. Did you disable abblock?

Depends, really. You can get a Kill-a-Watt meter to get a good idea, though. Had an old PC I was using as a pfSense box that was costing $200/yr in electricity. :(

Of course not, I'm not a cuck.

I should get one before moving into my own apartment. I'm trying to figure out if its worth just running a small NAS as opposed to my main desktop 24/7 for streaming.

Those parts will work with your current PSU, as long as you don't overclock your shit. If it turns out that you don't have enough power, a decent PSU will shut down to prevent damage. So trying it out won't hurt and if it turns out that your computer randomly shuts down when it's under stress, you'll know that it's time for a newe PSU.

>>52420844
Yeah, this seems like the best solution.

>>52419521
Any single gpu system with modest intel cpu will draw less than 500W (most likely around 350w-400w under full load), so going with something like a 550-600W power supply is perfectly fine if you get one rated 80+ gold or higher. Since those are underrated in wattage, you'd be within the optimal operating wattage for maximum efficiency.

Most 80+ platinum power supplies are dead silent as well and don't even turn their fan on until 60%+ load.

That's useful, I'll make sure to look for one of those if I end up needing it.

Good because otherwise I would have made a joke about your wife's son.
