Finally a comment with actual relatable DATA…🎉😊

Very informative video, I really enjoyed it. Apparently with these new power supplies it isn't really necessary to buy bigger just in case to avoid crashes. Of course you still need to buy a reasonable size for your use case, but at least it shouldn't crash if some component (most likely the GPU, I guess) pulls more power than expected for a few milliseconds.

Very well done, thank you.

This video answered a question that I had on my current 3900X/5700XT system because I suffered a black screen with my Seasonic 850 watt PSU running transcoding software that utilized my 5700XT. My next system will allow for spikes and use a more efficient GPU... such as Battlemage.

Love the series 🙂

I bought the sfx_l rog loki 850w platinum for my 4070ti and 13600 k the thing is that its in an atx build did i make any sort of mistake there? Does that make the psu unreliable?

This year in particular, I don't think that I've seen as much stupidity in the PSU market. No availability of ATX 3.0 PSUs and LMAO none of the PSU companies had a working calculator for the current CPUs and GPUs until a month after launch. Brilliant! Absolutely brilliant!!!! 🌟🌟🌟🌟🌟 5-star in Duh!

This was quite an informative video.

I also like to over provision the wattage so that it doesn't have to work so hard. If a PSU runs at close to the rated value it'll run hotter and doesn't last as long. Also, the hotter the more noise it will produce to get the heat out of the psu. It's good to know the power settings of PL2 is an average, it can spike up (far) above that. A good power supply should be able to take short duration spikes though. So I'm not sure this feedback feature is going to be that useful. Only scenario I can think of is accidentally putting a 4090 or more power hungry GPU in a system with a small PSU that can't handle. Well like that's ever going to happen, right? Another use case would be if the PSU is getting old and the components like electrolytic capacitors, especially the high voltage ones may have worn out and spikes are getting harder to cover. The PSU would last a bit longer if the CPU scales back at that point, also indicating that it's time for a replacement. A soft failure is always better than a hard failure. But both are pretty niche usecases. I'm sure system builders will be able to push the price points further down at the cost of quality components. I'm not sure if that's a good trend.

Thanks for review.

I’m interested in the efficiency, zone and noise at load

LabView system! Cool, first time I see being used outside of a school.

The hardest part is finding a reputable small PSU for a low power system where you care about efficiency (eg for a low power server or iGPU build) Q: Why is every reputable retail ATX/SFX low wattage PSU bronze/white, but you can get stuff like that in micoatx and flexatx form factors

also wondering if geek bench scores is low due to cpu sacrificing its performance for it to not shutdown, is there anyway to inform users that the system power is high and 12vo is limiting cpu power and show the users like windows notifications?? or else like intel software in the background? cause shuttingdown because of power insufficient of psu is a big slap message to user but 12vo unless youve run geekbench you can see the effects of throttling cpu power for staying a system alive and not to shutdown.

@Vegemeister1

There's an MSR with bits that get set for each throttling reason (power limit, temperature limit, external signal from VRM overheating, etc). I can't say for sure without looking up the manual, but they've probably assigned a bit for I_PSU% throttling. Microsoft (or Intel in their platform driver?) would need to make a service to check those bits and raise a desktop notification.

I wish you could test with a 1000w psu to see the max spikes for 13700k and 4090

will this help with overall effishanty power to watt ratio

Nice info

What will happen to your containers of power supplies?

I am finding that most calculators are grossly higher than what you should get, probably to cover their asses. I ran two tests recently. One PC with an i9-9900 and an i5-6600k. The i9 has 32gb ram, a 12gb 3060, 2 X 2tb NVME drives, a 20tb EXOS, and a blu ray drive. The i5 machine has 3 X 1tb SATA SSDs, and a 2070 Super. The i9 has a 650w PSU. The i5 has a 500w PSU. I plugged both machines into a 1000w Jackery Explorer and ran Cinebench for a max load. The Jackery has a built in wattage meter. i5 machine peak wattage was 225w under a max load. The i9 was 215w. The Newegg calculator was the closest at both machines from 500-600w. I feel comfortable with the PSUs (both Corsair). I’ve had no issues with either machine, and the i5-6600k is being swapped for a lower power consumption i7-7700. 650 - 750w is probably the sweet spot for over provisioning while still saving some money.

Seasonics new atx 3.0 coming out later this month are cheap. 280 for 1200w and the prices drop from there.

I never knew till now that a 13700K CPU can draw up to 300w from the PSU. I had looked at the specs that tell me it is 125w and assumed that was what it drew. I learned something new. I would be fine with a 850w PSU with a B760 mATX board, a 13700k and a 3060TI GPU, yes? Or should I go 1000w? Or even 1200w?

How about doing a similar video for AMD.

We kind of already knew 13 gen Intel can use a lot of power. This is the new normal vibes for 25 min. I almost fell for it... for like 5 min. Except 12600k, many AMD, eco modes and voltage limiting, etc exist. RTX 4090 kind of requires super CPU. But that's niche and only 99% true. As for ATX12VO I look forward to it. I have no cables besides 12V CPU, GPU and MB in my system. All my drives are NVME for a few years already. And that fat old 24pin MB cable looks (and is) stupid here in 2022. Unfortunately for now there are just a handful of power supplies and even less MB with 12VO afaik.

I think this episode kinda backfired because it adds to the FUD around PSU's and creates a lot of uncertainty about how much power a CPU uses, (except the one particular CPU) and voltage spikes featured in the video.

I can help you out Gordon. Buy yourself a small form factor case and everything you can fit in it will be fine with a 650 PSU.

I won't be sizing up any power supply until ATX12vo comes out. Energy efficiency is no.1

So if I understand Gordon right, I should buy a Seasonic VERTEX PX-1200 for my theoretical i3-8100/GTX 1650 or risk my house catching on fire??? 😂

A 1200 for an i3 *wheeeeeeeeeeeze*

Couldnt you measure the power suppply input as a whole and have a piece of sofware installed on the system to read this and feed it back to the cpu?

The efficiency of the PSU is calculated based on its load, meaning that it will be, let's say, 90% efficient at a certain load and less efficient at different loads. If I size the PSU thinking at the spikes, there is the risk to pick a PSU way more powerful compared to what will be the average everyday load. As a result, wouldn't this PSU be less efficient compared to a less powerful one? If this is the case, what is the point to pick a 80 plus gold PSU then? The only advantage would be given by the quality of the components, like for example the ability for the higher tier PSU to work at an operative temperature of 50°C instead of the usual 30°C or 40°C offered by cheap models. I'd rather size the PSU thinking at the TDP of the components, leave me a 100W margin over the estimated full system power consumption at full load, undervolt both the cpu and the gpu, and don't do rendering with both of them at the same time. Seems more reasonable, or not?

@@jelly8594Obviously you never tried to design a mini pc so you don't care. But for me it is a hobby, so I care. The problem with a 24+8 (32) pin connectors are not the connectors, but the fact that they force you to route 32 cables trough your case up to PSU, and if the case is small they take a lot of space, block airflow, and made several parts difficult to access. And that is because a legacy design from the 90's, totally unnecessary nowadays. Today we can have high gauge in very thin affordable cables that were not available in the 90's. As an example the new 12VHPWR standard can carry up to 3 times the power of those 32 pin, and it does so using a connector that is 4 times smaller in size and only use 8pins for power and ground plus 4 control pins. All other areas are improving, in fact there are laptops over 250W that only need a small barrrell, and in the smartphone arena the USB-C can carry up to 240W. But the Jurassic 24+8 pin connectors are still blocking SFFPC advances.

Dont cheap out on your power supply. The power supply is an overlooked part of PC building because quite frankly its a boring piece of hardware, but if you purchase a good power supply now it is one part that can move with you far into the future on multiple different PC builds and upgrades. Its one of the reasons why I always oversize my PSU as well. Oversizing your power supply means it doesnt have to work as hard, which means it will last longer. If you decide to build another system in a few years, chances are that same power supply will be plenty of power and have plenty of life left in it to power your new system. So spend the money now on a good quality oversized power supply and you will save money later.

Yes well if you leave it too long before upgrading you find your old PSU isn't fit for purpose anymore because you need new different connectors or some other changes that necessitate you buy a new one. If you buy a PSU that's built like a tank and can easily work for 20 years without trouble, it can be obsolete in 5 years.

This is how I pick my PSUs: 1) I buy a top-end PSU rated for 1000W. (like my OCZ Z1000M & EVGA 1000 G2 Supernova) 2) I never worry about it again.

TL;DR Don't cheap out on your PSU. Get a PSU that's rated at 200% of your system needs since PSUs are most efficient at 50% power usage. And buy a Seasonic since they make high end PSUs for other companies anyway so just go to the source.

Stephen Eastman has to be of very recent Irish ancestry! Looks extremely Irish!

So he came to show us how dangerous Intel CPU's are. Thanks! I'll make sure to get AMD next time 👍

Save now and be sorry later or Better to be safe than sorry? I choose the latter. I kept the PSU from my first two builds because I bought more power than I needed. I bought more power than I need for my current build because eventually I will upgrade the CPU and/or GPU and the HDD. Buying just enough power might mean you may have to get another PSU when you upgrade your components. You're not really saving any money going that route.

With this feature, I anticipate a lot of stuttering in the future!

The title is entirely misleading. This video doesn't tell us how to pick a power supply wattage at all. There's no information of how to choose a power supply.
