There are a few "great value" PSUs out there, and they're _far_ more practical for the cookie-cutter PC build. But if you want the best, you'll pay for it.

@@Mach141 yeah sure my ass. Caps dont last forever and they sure as hell dont like heat.

[@OtakuSanel]

@@DarkoPetreski I have a 12 year old thermaltake toughpower 1KW. While it's true caps don't last forever, if you get a powersupply with rubycon or nichicon caps they will easily last 10 years and actually longer if you keep them cool. Unless you have a silent version where the fan turns off, the constant stream of air from the psu fan is more then plenty to keep them nice and cool. Notice even under extreme load PSU exhaust air isn't actually very warm? Buy good quality and over rate it to begin with and you can easily get over a decade out of power supplies. Heat is the main thing that kills capacitors so that's why gpu caps and mobo caps fail since they get very hot but psu caps don't (if you get quality ones to begin with and they have airflow)

[@jameysummers1577]

Hi

[@LordPhan]

Many years ago I read a post on the EVGA forums, which was responding to yet another 'Is this a good build' thread. The post was concise and to the point and I still remember it. It said: "I'll never understand how so many people will spend thousands of dollars building a pc and then cheap out on the ONE part that can BLOW IT ALL UP!" I still remember it to this day.

[@635574]

I really dont find a lot of discussion babut psu ratings and efficiency

The lowest I’ll go on a mid range build is 80 plus bronze. Higher grade hardware, and I’m not using anything below gold

[@filds1]

@@LordPhan or when they build a 9900k and get a hyper 212 evo. You say get a better cooler they respond what you know my friend build it for me. Then after few days they come again and ask why they are getting lower performance while playing a game.

[@wkwk2o384ur]

Honestly you should use an oscilloscope to measure the output DC from a range of different price/quality power supplies. That way we get some actual solid results instead of taking the manufacturer's word for it.

[@Mictian1980]

It’s literally the verge’s power supply

[@qT_p13]

Quick correction. When someone refers to AC being "sinusoidal," what it actually means is that it can make you sneeze if you suffer from allergies, as you may tend to be sensitive to the fluctuations of current in the air.

[@NuclearTopSpot]

oh that explaines the benadryl i got with my latest corsair psu

[@FelixEFX]

Literally all modern power supplies use microcontrollers. Pure marketing bs! Worst psu ad video I've seen in years!

[@aljgp]

Yep, The place I work supplies DC PSUs for Telecoms & Industrial applications, and every single one of our rectifier products (and inverters for that matter) all use DSP microcontrollers to maintain the operation of the rectifier, in fact we have been doing this since at least the turn of the millenium. All our kit is 96%+ efficient upwards of 2kW output. Its always amazed me that PC PSUs relied on analogue conversion and control methods.

[@JonDisnard]

@COFASA mosfets are the source of coil whine in all electronics. The video didn't say that, I did. We would not expect a KZbin shill for a PSU vendor too explain this.

[@primorock8141]

Can we talk about how lovely that power supply looks?

[@t3rb0rg]

One other note -it would have been good to show in the graph that unlike other 80 Plus ratings, 80 Plus Titanium also requires 90% efficiency at a 10% load on the power supply. No other 80 Plus rating has a 10% requirement, meaning that Titanium power supplies must run more efficiently under lower loads.

[@Teh509]

Floyd to ACDC reference... you immediately elevated yourself in my books.

[@jamespickell3915]

I’m still out here running a evga 400w non 80+ unit, probably should upgrade

[@erusman727]

That's one sexy power supply. Haven't used be quiet! brand yet. Still sporting Seasonic PSU's. Most reliable PSU's I have come across. I have one that has been running for 7 years so far. While corsair, evga etc brands I have used died within 1 or 2 years. May have to give be quiet a try. 1200w is alot. I would only use something like that if i was running multiple GPU's. Even with a 10900k and high end GPU your going to push max or 500w. On average though I pickup a 750 or 850w. Leave a little room.

[@XxViciousxX]

Seasonic is awesome whenever I build a PC for someone I almost always use Seasonic. My two personal PSU’s are a Rosewill Glacier 1000w that is 4 years old and a Corsair RM 1000W that is 5 years old.

[@kyleforgeard4148]

Really. i have a very cheap raidmax psu and it hasnt died yet and my pc runs 24/7 had corsair psu that was 8 years old but think it started to give problems have one in other system will see how long it lasts. Will definitely try seasonic next

[@epicmike3915]

399$ power supply aight I'm out

[@Znerox]

I'm studying electrical engineering, and I still don't know what the heck "digital power supply" is supposed to mean. Are they using MOSFET instead of BJT?? This is just an ad.

[@OtakuSanel]

it's marketing bullshit, they say that like it implies others don't use FETs but ALL PC PSU MANUFACTURERS USE FETS as the main switching device. A power supply is inherently analog so the whole digital thing is even more marketing wank. They are labeling it as digital in the sense that the voltage control is done with a micro-controller but that's pretty par for the course for anything that's not bargain bin junk.

[@bruceg22000]

This is the most important component as far as I'm concerned. I have a 80 gold plus PSU, but after this video, I may upgrade to a higher category for my next build.

[@chemicalbreath]

$399 is a lot of money. My Cooler Master V1000 as been going strong for 7 years now.

[@TwinShards]

I've got myself a ~$150 SeaSonic Platinium 750w PSU. And i'm more than happy to have choose it. There has been quit a few general electricity shut down for a few fraction of second and my pc always stayed on but all my monitors, internet has shut down. There has only been one micro electric break that has force turn off my pc. It didn't turn off instantly. The system killed itself for safety because there was not enough electricity remaining in the capacitor to stay turned on.

[@TheElement255]

And it can short out with the chassis of the case if you don't install the rubber feet

0:44 "we partnered with bequiet". He did say it, but I feel like he could have made it clearer.

[@Artemis_WR]

does it have software control like the nzxt ones? if not is not worth for me.

[@jra]

So if I buy 80 plus Titanium accounting it's higher price apart from being more power stable so much safer for my components, It will "reduce" the power consumed? I mean if a less efficient psu can loss 20% of "converted" power as heat and not converted in actual energy to be used it means more power need to pulled from the wall right? So in long term less money wasted in the bill?

[@Mr1Tanker]

When i hear the word digital, my sphincter puckers up tight!

[@Grompulous]

Really enjoyed this level of detail in this video! nice and clear explanation of the difference between this and a traditional PSU without being too simple or being too in depth and inaccessible either. Just curious if having digital controllers for so much of a unit like this could reduce the lifespan with more points of failure? despite offering a better solution while it works as intended.

Hey Greg I have a random question.. if I wanted to sell a used rig that has an old b350m-a Asus with a Ryzen 7 1700 32gb lpx 3000mhz Corsair ram 1tb WD blue m.2 nvme thermaltake 650w 80 plus gold fully modular PSU PNY GTX 1080Ti, 4 nocturnal NF-F12s in a Phanteks p300a what would be a fair price in your opinion?

[@SirMrDany]

So my way of doing PSU is throw money at it.. and the ROG THOR 1200W I use seems to not be doing well with my 3090.

[@killertruth186]

$50 for an EVGA 550W is a good deal, although there's no efficiency rating on them. As far that I had used it, I don't have to clean the PSU (by using vacuum or the air cans) every few months. after heavy use. And I had used a longer cable for the PSU, because the ones that EVGA had it with is very short. That is one of the cons of the PSUs.
