How Many Watts Does A Smartphone Draw

• #ii

You tin can use a tool similar this. You enter your hardware and it volition calculate a wattage for yous.
What PSU do y'all currently have?

Those PSU calculators commonly give you very inflated numbers, attempt looking upward some reviews which have a like setup to yours. Biggest power draws are the CPU and GPU, the other components (RAM, hard drives, fans, etc.) don't really use that much ability. Overclocking will also significantly increment your power usage.

Simply yes, it would be useful if yous list your current setup and the GPU which yous're thinking of getting.

Hmm, I didn't know that. I've never used ane personally simply, I did assume they were some what accurate.

Purchase a multimeter, or expect up each of your components specifications from the manufacturers website. They will give yous max TDP, only you will want to have that covered +20% anyway.

When I type in my setup I get 952W from that Newegg calculator, and I assume that's for everything at stock. I accept a 40% OC on the CPU and 20% OC on both the GPUs and have never had issues with a good quality 850W unit. It's definitely proficient to take some headroom but don't desire too much overkill.

....and they laugh at my ii.2kW triple PSU setup ROFL
This is without the water pumps, fans, SSD, lights, etc

...anyhow you want a 20% headroom with your PSU for heat and efficiency reasons.

They recommend 464W for my setup. I'm running an Enermax Noisetaker Two 485W PSU. I also accept a Kill-a-Watt meter, and when I had an 8800GTS 320 I don't think I ever saw it pulling more than 270W from the wall while gaming. I now have a Radeon 5830, which may pull less than my 8800GTS 320 did.

PSU ratings are unremarkably for when the PSU is at 20-25C for nigh brands (which is a useless temperature to rate a PSU at imho - who has a PSU running at 20C at load?). They can de-rate at higher temperatures quite significantly. Likewise as they age they de-rate equally the components degrade so all this headroom is a very good thing.

So while yous meet 270W describe, your PSU capacity at reasonable temp could exist a off-white bit less than 485W...

They told me I needed 320w, which isn't a bad estimate actually.
I'chiliad running an Antec Earthwatts 380w, and I do have a kill-a-watt meter only I've yet to endeavour it out on my computer.

They tin de-rate at higher temperatures quite significantly. Also as they age they de-rate equally the components dethrone then all this headroom is a very skilful thing.

So while you see 270W describe, your PSU chapters at reasonable temp could be a fair scrap less than 485W...

I know. But my point was that the PSU reckoner wants a 464W PSU for my organization, but in reality my system pulls 270W from the wall under load. Taking that load reading from the wall removes the necessity to deal with inefficiencies in converting AC to DC, so unless my PSU degraded in its capacity to around 50% of its rated, I wouldn't have whatever problems.

The 464W is a VAST overestimation for my item setup. I'm not saying this will be true across the board, simply throwing some support behind slh28'southward comment.

I support that comment too, if you're unsure you should ask here (before you buy not after).

Peradventure the calculator is factoring in some padding... worst case scenarios for HDDs, video cards with overclocks etc...

Also PSU efficiency is usually best well inside the max capacity (closer to 50-70% of max). I wonder if that is also factored into the calculator?

Possibly the figurer is factoring in some padding... worst instance scenarios for HDDs, video cards with overclocks etc...

Much more than than necessary IMO.

• #sixteen

If you have to ask, then you're non sitting on any kind of computer powerhouse, so have the recommended wattage required for the video bill of fare y'all want to purchase, and add together 100w.
