how large of a Power Supply does your computer need? #shorts

I recommend at least 100W buffer. Especially with cheaper power supplies.

Also in case anything gets upgraded or new storage drives get added.

(Edit: Spelling)

[kiwimonster]

50w overhead seems little bit small especially when CPU is turboing

[WhileGeek]

I bought 1000w Corsair Psu 9 years ago and now i am using my 3090 with it I love my psu

The real question is how much thermal paste does your cpu really need

[gimmickmusic]

This isn’t necessarily accurate. Especially with modern nvidia gpus. They supposedly have a max power draw of 325W, but they can hit transient loads that will spike to 400+ watts for a few moments. That kind of jump is more than enough to trip overvolt protection on any half decent GPU if you aren’t rated for it.

[kikihun]

The best ration is the needed watts×2
The psu is more efficient when running at 50-70% load.

[viduranisal]

Old video? Pascal was quite power efficient, latest gen GPUs are pushed over 2GHz and can have massive spikes. Not to mention perpetual all core turbo on Intel with most motherboards. Given that PSUs are most efficient at 50% load and will last a long time when kept under 80% load, adding *at least 25%* as a buffer would be good with newer power hungry parts.

Note** when a CPU has a TDP of 65W, that doesn't mean it uses 65W maximum, that is the pl1 power aka idle clock, however there is also pl2 power also known as boost clock which can be significantly higher, like for example, the 11400f has a TDP of 65W, however when boosting, it can go up to 150W or even higher.

You defo need a buffer, also make sure it has safety features like surge protection, and also it would help if it's noise was low, that's usually the main 3 things one should be looking when buying a power supply

[sajjadhossanshimanto]

If you don't have POWERFUL GPU and you use mostly normal parts you can go with 500W without any thinking

[dexsters]

There some good psu calculators out there which can help for thoose who dont want to math the wattage.
Outervision psu calculator is what i used and its accurate

[dusannestorovic]

Also, dont be afraid of using a more powerfull PSU even if you dont need all the power, its actually more efficient than using one that is barely enough

[TheRealHiro]

Considering psus are most efficient in the ~60% draw range you should use one just short of double your draw. Also, a 65w tdp does not mean 65w draw a 5600x is 65w tdp, but under load draws around around 150w

[ADreamingTraveler]

You can get away with the exact number or even slightly below that but having that 50-100w buffer is always recommended. It'll also keep your system healthier and last longer so always get something that's 100w over what you actually need. Your power supply is the most important part of your build because it powers all your other components

[crowman]

For the Buffer, it is better if power supplys work at around 80% power so you can calculate how big of a power supply do you need, for example if you calculated 350 watt usage, you multiply it by 100, then divide it by 80 so 350*100/80=437, 5, then round it up to closest power supply you can find, so you shoudl use 450 watt power supply

[chiyolate]

You should double or even triple that to be safe, not just adding 50W, it also gives room for future upgrades.

[OmegaHellHound]

I use 750 or 850. It’s more than enough, and affordable enough. Plus, the more the wattage of the PSU, the less strain your system will put on it, which will in turn make your PSU last longer.

[DiamondDepthYT]

I just bought a 650w psu for my PC. I have an i7-4770, 3 120 fans, GTX 1650 SUPER OC, 32gb of ram, a 1tb ssd, 256gb boot ssd, and 2tb 7200rpm hdd. 650 is slightly overkill but allows for some future upgradeability

[shakuroh]

PSU I recommend: XPG Pylon, Be Quiet U9, Corsair CX, XPG Core Reactor, Corsair RM and Seasonic Focus GX or CX.
If you need something like an I7 10700f and a 3060 or lower, go for a Corsair CX, XPG Pylon or Be Quiet U9, but if you need something more powerful, go for the Seasonic Focus, XPG Core Reactor or Corsair RM.

[ariefnugraha]

Nice video! Rather than 50W buffer, I prefer use 80% buffer.
For example :
341 / x = 80 / 100
X = 426.5

So you need at least 426.5 watt power supply!
