the computer power supply it's almost as mysterious as the phrase I'm fine just leave me alone I mean what does that even mean if I actually leave you alone to go play video games will I be making a huge mistake and will I pay for it later I mean if you were fine wouldn't you want to talk to me like you normally do and if you're not fine when it blows up later but it'd be your fault for not communicating clearly or my fault for not understanding please just tell me what you want anyway so while I'm not qualified to help you understand women I can help you choose the right wattage power supply for your PC step one is finding out how much power you actually need for the components inside your PC this is expressed in the total number of watts that the unit is capable of outputting and the best way to find all that out is to head over to Coolermaster outer vision comm it's linked in the video description and enter the stuff you're using or plan to use it's that simple if you run into anything confusing just posted in the Linus tech tips comm form under power supplies and our awesome community will help you out now that calculator does add a bit of fudge factor for stuff like the aging of your components over time so it might air on the side of a little bit too much but it's best not to try to squeeze under that and use something insufficient that can result in unexpected shutdowns and wear and tear over time now some people will naturally go completely the other way and see four hundred watts in the calculator and figure well to be safe I'll just grab a 1200 watt power supply but that's not necessarily right either first your wallet will be more empty than it had to be and second your system efficiency will actually be lower than if you bought something more appropriate a power supply operates optimally above about 15 to 25% of its total capacity that means that your system will actually draw more power from the wall than it has to and your power bill will cost a bit more sounds terrible right well sometimes it makes sense I'm one of those people who went overkill on my power supply but it's because it has a fan 'less zero decibel mode for complete silent operation when I'm not fully utilizing my PC an example of this is coolermaster silent pro hybrid series which doesn't even turn on the fan until it reaches 200 watts of load so you can train a bit of efficiency for quiet if you're into that step 2 is finding a power supply that matches the wattage your calculator spat out there are two ways that the capability of a power supply can be expressed as peak wattage or continuous wattage now I have a hint for cutting through the BS here if a power supply is rated in continuous then that's good if it's rated in continuous with a separate peak rating then that's good too if it only has a peak rating then don't put it anywhere near your system because there's no real standard for what peak means can it handle that for an hour a minute a week I split second before it goes nuclear we don't know if a power supply is rated only in peak wattage but not continuous don't even consider buying it which leads us to the final step picking a power supply of sufficient quality it's important and this isn't one of those used car salesman moments here guys I get asked all the time why I don't review the latest power supply with a hundred multicolored LEDs in an acrylic case from Jack Tech and the answer is that I don't care about it at all a power supply is a serious piece of equipment not a fashion statement and unless it's from my trusted manufacturer with all the appropriate safety certifications and/or gets a seal of approval from Johnny guru or a similarly reputable power supply review site I'm not gonna touch it a power supply can fail spectacularly triggering the premature or even immediate failure of other components in your system and your warranty will not cover you being a doofus and relying on a potato to provide safe stable power to your PC and that's not even the worst case scenario a fire caused by a power supply can burn down your house on that somber note our sponsor for this episode is cooler master and the only power supply brand you should ever consider buying is cooler master because I'm just messing with you guys cooler master would have to pay me a lot more than they are to pretend that they're the only solid power supply brand that exists in all seriousness though this video was brought to you by Coolermaster and they are one of the solid power supply makers with options ranging from value oriented solutions like the GN series all the way up to the V series which includes modular cabling extremely low ripple and uses only high quality Japanese capacitors and I think we're done here if you guys enjoyed this video and you're shopping for a power supply it is definitely worth checking out the sponsor link in the video description to see if they have anything that
