8:30 Its a Titanium rated that has a minimum efficiency of ~90% at 100% load on 115VAC. Therefore 754W input would be ~678W output, which is only about 4.4% over but is probably within the design tolerances. Also, if your were running this on 220VAC you'd be at >94% efficiency and well within spec.
@m4ster_root2 жыл бұрын
The 650W is what the unit can output. It doesn't matter if you're running at 115VAC or 220VAC the specs are the same. The efficiency is different, that's correct, the higher input power the better efficiency. A 650W power supply is rated for 650W output. At 100% load it'll consume ~722W at 115VAC and 691W at 220VAC. So yes, the numbers Linus saw was well within tolerance of the unit and not surprising at all. Sustained load seems to be around the limit of ~722W with a few higher peaks but nothing that should trigger OCP for a good unit.

Being more efficient at 220VAC won't make it more or less within spec. It'll just consume less at the wall, it'll still output ~678W and be a bit over spec, but surely within design tolerance.

The 650 should be the max continuous output provided by the PSU to the components. The PSU can pull more from the wall to provide that. Thats where the 80+ certs come into play. The less it pulls from the wall to provide that continuous power, or the power efficiency it has, the higher the certification. So having the PSU pull 750+ from the wall and the game continuing to run isn't a big surprise.

An interesting adventure for sure, and I think the main takeaway really is don't sleep on the power of under-volting components. A lot of work goes into deciding on stock settings that account for manufacturing variability, but you may be surprised by how far below stock voltages your particular unit can operate if you have the time and inclination to fiddle with it. Lower power draw and cooler parts; a straight up win-win. That being said, please don't skimp on your power supply. There's generally no downside to going overkill (aside from cost), and often even a slight efficiency benefit. A power supply that barely meets your system demand WILL be problematic in the future as components age or your peripherals change (seriously, I've encountered systems running so close to the edge that raising the brightness of the keyboard backlight too much was enough to cause instability, and they are not fun to troubleshoot). If your budget is that tight then try and cut pretty much anywhere else first.

I underclock, FPS limit (RTSS), and power limit my GPU and CPU--because I buy these high end units. The limitations keep things cool and allow high FPS at good power usage. This because the improvements in technology mean that performance is exponentially better at lower power settings, in as much as they increase exponentially for higher clocks. This also affords quieter operation, since these units come with larger coolers meant for much greater power draw. Remember that the RTX 4090 is twice as fast at the same power draw as a 3090, so this is a big win at even lower power levels. Yet, for all the benefit of better technology it seems that companies are pushing for higher performance wins rather than efficiency wins. To a certain extent, Moore's Law holds true in terms of an exponential increase in efficiency as tech improves. But companies want to show "big numbers" to sell product, and efficiency isn't as appealing to people as "moar speed". Overall, this really sucks because efficient tech is really important to a greener economy, and the sales-driven-mentality is not compatible with a green future.

I can't even tell if this is meant to be facetious. They're only doing this because AMD's RDNA has been getting better linearly whereas nVidia's RTX has been going in the opposite direction: downhill ever since Pascal. This is why so many people switched brands with the 5700XT, most of whom only went back if they were the zeroday launch buyers who were among the unlucky ones with driver problems (I personally didn't have issues it only had a blackscreen out of the box with FreeSync on by default with overvolted default BIOS which I turned that off and used EnhancedSync instead and never had a problem with it, been graciously happy with it since so much I'm still not upgrading this year). Anyone else is and has been steadily switching to AMD, which is only the sensible thing to do at this point. But really it depends how much they charge, because if it's even vaguely vidia-like then they're both ripping us off, only AMD less so. And even then, let's be honest here Ampere was a shitshow it was because AMD fully caught up to nVidia with RDNA2 and they knew it, hence the absurd power draw and using R9 Sapphire Nitro Fury pass through coolers from a decade ago to try to keep the thing from thermal throttling on RTX 3000. And then we get this shit, and I knew once I saw those TDPs that AMD already basically won. They're going to be cooler, smoother, more efficient, less stuttery, probably have better frametimes generally, and have a better pricetag. What was it, the GT 280 or something like that? The last time nVidia got forced to slash costs because their cards were literally worse than AMD's but cost $250 more? So nVidia had to lower their flagship from $650 to $400 just like AMD's better performing more efficient, what was it the HD Radeon 5970 or something to that effect? So here's where we are now. Basically all I just see is simping for a company that doesn't love us and making Intel fanboy-like rationalizations for a company that's desperately trying to keep up, and meanwhile the only sole reason we even have nVidia scamming us so hard is because nVidia fanboys watch Jensen fuck their wallets and they love it. I for one don't. I refuse to purchase their crap until they lower prices, just like I adamantly refused to buy a new RTX card back in 2021 and just like I refused to pay for the overpriced crap this summer because there's no way I'm getting a 3050 for $350 that's a complete scam. Meanwhile RX 6600(XT?) was like $100 cheaper and it outright slaughtered the 3050. >b-but muh features! on a 3050, which literally doesn't matter because a 3050 performs worse than a 5600XT so you're not gonna be getting to use raytracing anyway, not even with playdough-and-ghosting tier upscaling. The fact these kind of things get justified is why we have outrageous pricing, because the corpos are going to keep jacking the prices until enough people refuse to pay it, which is exactly why this "inflation" i.e. price gouging throughout the economy happened so bad anyway, because all the corpos realized they could charge literally whatever they want and just blame the government's monetary policy and people would blindly buy that (probably 60-80% of all cost increases this year has been solely runaway corporate greed, watch these CEOs in interviews literally saying they realized they can charge whatever they want and only will stop jacking prices when "the consumer finally refuses to absorb the cost increase") So mark my words, in approximately 3 months time all the flamewars and shitflinging is basically going to be because AMD just beat nVidia across the stack finally, having already reached parity up the stack last year, and with their sole advantage being a really marginal edge in raytracing the whole argument will be only "you should buy nVidia no matter what it costs because they do raytracing about 5fps better at 1440p" You can screencap this because that's literally what's going to happen January 2023. They're literally going to be justifiying and rationalizing buying outrageously overpriced hardware based solely on the metric of RT, because AMD would have already shown itself to be the better buy and much better made hardware.

Underutilizing a high spec power supply actually costs you more in the long run assuming it doesn't hit its peak efficiency rating. Universally PSUs hit peak efficiency at around 50% load, if you had a 850W PSU and only used 300W at full load you're wasting energy. This is also why leaving a PC idle is detrimental with most PSU because you're in the 75W range at any given time, which is super inefficient on any PSU but especially higher wattage ones.
@PileOfEmptyTapes2 жыл бұрын
@@CarbonPanther That being said, efficiency at lower power is actively being worked on, and some modern supplies actually get close to the ATX 3.0 target of 75% at 20 W (e.g. Corsair RM550x 2021, arguably the current low-power king though it's only average in the 50-100 W range). Seasonic's current Prime Ultra Titanium line seems to have regressed somewhat over the older Prime Titanium, which posted excellent efficiency values but apparently also had a certain penchant for blowing up. No free lunches here. In an 850-1000 W PSU, an 80Plus Platinum rating generally is about the minimum that you want. A Corsair RMx 2021 should be better than expected at low power despite being "only" 80Plus Gold, but expect ventilation needs and hence noise to increase at high loads. 90% efficiency at 900 W means 100 W of heat dissipation, and that's quite a lot for a power supply to get rid of.

something to remember... those output "watts" are mostly coming from the power supply's 12 volt rail. The PSU rating is often just a nominal value, not a true combination of every rail available on the device. For instance mine is "650W" but it actually outputs 722W if you account for each rail. It might leave more headroom than you think....maybe not enough to make-or-break the system, but the numbers are a little more fuzzy since the manufacturers don't like to use detailed datasheets for their exact power consumption anymore :(

It would be like saying an Olympic bar can support 10 tons of weight without snapping so a powerlifter can bench 10 tons, that's just not how it works, just because the bar isn't the bottleneck doesn't mean the powerlifter can now match the limits of the bar too.

Yeah uh, the power savings tell you exactly how much heat isn't being put out. PC using 1000W? It's the same as a 1000 Watt space heater. Save 400W of power? You now have a 600W space heater.

don't think you understand how power works lol. every single component in your house minus a few, active heat your house by the exact amount of power they use. That 20" box fan you have? yeah it heats the room to the tune of about 100w of heat.
@Florin_Neagu2 жыл бұрын
You have to remember that heating power in watts is relative to room size, insulation, air circulation, outside temperature, etc. The Watts/inside temperature coefficient is not a fixed value. The % of reduced Watts will not equal % of reduced temperature unless the pc is the only source of heating in the room. But let's say you're running a 4090 + 13900k, and between the two of them you're drawing 700W. Say you reduce that by 100W, which is a rough 13% reduction. Even if you were to apply a linear reduction in temperature, from say 30 °C, you'd only shave off around 3°C. Of course, the reduction is far from linear, so you'll never get that sort of ° reduction, it'll be more like 1-2°C, if that. Naturally, the above assumption is that the outside temperature is much lower than the inside temperature. If it's 35°C outside, you'll never be able to drop under 35°C inside as long as there's a source of heat and/or no source of cooler air.

Undervolting my rtx3070 gigabyte eagle was the best decision I ever made. 20C!! less temp under load from 90 to 70. 10-15 higher average fps in heaven benchmark with only a loss of 1-2 max fps. And in games it feels like it had much less frequent stutters. Also applied a 400mhz memory overclock which is in the very safe range. Highly recommend if your card is running hot. Also it saves power of course. I set the voltage to 900mV and frequency to 1975.

It's actually very likely not being exceeded. 700 at the wall is irrelevant because PSUs are rated for available power on their output side. Accounting for conversion efficiency and filtering losses, it's almost certainly performing well within its listed range.

The graphics cards will obviously get bigger physically, so what is needed I think is an external PCIe interface along with a dock so that you can plug in your gpu the same way you plug a printer, a mouse or a keyboard (said "GPU dock" would have its own external power supply). Then, the GPUs could get as big and powerhungry as they want.

the power rating is output power. Hence why in north america they're limited to 1500/1600w psu's (depending on their efficency rating). Idealy you would have 1800 watts per circuit with a perfect 120v ac, but you likely have some losses in the wall and get 115, which is what most are spec'ed for. So they have to pull less than 1725 watts to prevent tripping breakers and creating fire hazards. Most power supplies are most efficient at 50% load, this means when bogged down to near 100%, its less efficient. Doing the math based on seasonics own data, the 650w at full load will pull 730w from the wall. So you were actually 100% within spec on the 650w. On the 550w it was just barely going over and really it was the momentary spikes that caused it to trip, as 630w from the wall was about 550w output (87.5% efficiency). You where 100% overloading something, but my guess would be if it pulled too much current from the one you had a splitter on and the psu detected too much current going through a single 8 pin as the gpu figured it was pulling from two different 8 pins. All of seasonics GX power supplies are single 12v rails, actually I think all their psu's are single 12v rails, but the connector is still only rated for 150 watts, and if the gpu decided to pull 300 through a single 8 pin, the psu should trip

for everyone that is trying to undervolt any type of card be smart. run it stock & pay attention to the highest frequency that it reaches before thermals increase bringing the clocks down. This will give you a baseline of what to put in Msi after burner. if you really want to control temps you must go -300 on the core at said millivolt at a respective frequency to really yield the results you want. currently have a 3060 running at 881mv with a frequency of 1935. but since the card doesn’t pass 55c at said millivolt - the card reaches 1950mhz & stays there. Anything past 60c brings your clocks down. On 40 series cards you have to much headroom to play with. it’s all trial & error at first but when you start to understand how it all works then you’ll figure out your card. Hope this helps someone trying to figure out how to really undervolt

And some people are happy to pay a decent car's price for a gaming system. Wonder when console brands realise they can slap a windows on their oem machines and have pc gaming back to 5-600 bucks and make the money on software and subscriptions like they already do.

@9:42 550*1.3=715w .. you're also looking at wall power and not considering efficiency; 80% efficiency plus 30% OCP headroom should show above 858w at wall..it's not rated to pull 550w from the wall with your efficiency dropping you to like 440w, it's supposed to be capable of outputting 550w sustained thus is going to require more from wall due to efficiency and also be able handle the peaks a 550w load would generate. Also ya need to exceed 30% more than the amp rating on a specific and/or all 12v rails. Which is what's happening shortly after but you at least correctly identify that.

It looked normal with no scratches. It wasn't in the cool bag, which was folded neatly on top of the PSU. But wow, it seems stable and nice. I like imagining going ten years and having it still be strong as anything.

I'ts impressive how the Seasonic 550W crashed. I had a 600W cooler master PSU from 2012, not even 80plus white. Installed in it a R9 5900x and a RTX 3070... Just for testing I stressed both cpu and gpu more than 700W from the wall and the PSU protection didn't trigger. Changed it for a XGP 850W Gold and now it draws 550W from the wall at 100% CPU/GPU (91% eff at 220v) (So, the CM600W had not even 70% efficiency) Some components where a little burned inside. I gifted it to a friend to power a Ryzen 3000 APU

Funny thing about Seasonic is I've had two of their power supplies fail on me in under three years while run way under spec. While my old Ultra power supplies, that snobby overclockers said were junk (and are no longer manufactured), are still running. I've had a few fail, but only after 10+ years. My newest one must be 8 years old now.
