550 Watt PSU Enough For 11700?

[MrBill2021]

I have a Seasonic Focus 550w PSU, would that be enough for the 11700 non k? Will just be using on board GPU.

 

[Selaya]

yes

you'll need this for suuuuuuuuuuuuuuuuuuuuuure

SilverStone HELA 2050 Power Supply is Hella Powerful, Hella Compact

SilverStone today introduced the HELA 2050 fully modular ATX power supply. This absolute unit packs over 2 kW of juice in a box that's just 18 cm in length. Typically, PSUs over 1600 W are over 20 cm in length. The 18 cm length makes this PSU fit for even mid-towers, if you've figured out what...

It's plenty. I'm running my 11700 non-K with unlocked power limits with an RTX 2070 using a 550 W Seasonic Prime Ultra Platinum.

 

[plastiscɧ]

well i do not want to put insecurity into this round but i am running a 1200W PSU @82% usage.. what am I DOING WRONG then?

With the specs in your profile? How?

As for me:
PL unlocked 11700: ~200 W max in Prime95,
RTX 2070 at stock: 175 W max,
Rest of the system: let's say ~50 W - I don't think it eats this much, but let's be on the safe side.

That's 425 W altogether, 450 if I move the power limit on my GPU as well. It might stretch a low quality 550 W PSU, but the OP's Seasonic should be fine (especially without a discreet GPU).

The calculated power requirement may deviate from the average power requirement in practice.
Our recommendation allows operating all PC components at full load. Since the highest efficiency is achieved between 50 and 80 percent load of the power supply, the recommended power supply works (on average) in the optimal efficiency range in practice.

That's what calculators on PSU manufacturer websites say in general, but if you think about it, the 80 Plus Gold standard specifies 92 and 89% efficiency at 50 and 100% load. That's a 3% difference. Does it really matter?

That can't be. The B560 chipset has a TDP of 6 W. Where would the other 79 W go?

i am unsure. some1 was not precise in measure maybe. and i do not want to blame u for it...
but 4W can't be

when upgraded to my 11700k (worse decision) my PSU 650watt (tried to sold it here as well) was not sufficient anymore. had to buy a new one. the 1200watts. and beside this it does not matter if Gold or Platinum or even higher. and this is my kind of personal proof. my XP i made. and beside this; i trust beQuiet in the fact of suggesting to 50%-80% usage. cus this is even the same with cars. when u hit the gas pedal to more than 120km/h speed the gasoline intake grows exponential. this is not exacly the same with electricity but 550watts is too close to the powerlimit in my opinion.

and this PSU calculator is possible even due independent sites with no manufacturers suggestion. the numbers stay the same

there is also ~6w for each ram stick and then being stepped down from 5v will have some loss (ohm) so assuming two sticks and chipset, ~20 watts rounded up.

its been my first hand experience that all online power calculators overestimate ~100 watts when comparing an online calculators' recommendation to what my kill-o-watt reading(s) were.

as an example (with numbers pulled from the air), plug in a fan in the input and it will assume 10 watts where as many many fans run less and 3 of them won't hit 10 watts. they, the cals, have a huge liability, its better for them to be safe and over estimate than cause harm. i'm sure we have all seen(?) 100% load on a cpu doesn't mean 100% power hog; 100% usage gaming will not draw the same power while rendering..

nothing nefarious, just being cautious - the problem of getting too overkill is when ppl start "derating" those over estimated number and get a 1200w psu for a 300w load.

btw, off the rip, yeah 250 watts for your cpu and 380 watts for your 3070ti; 630 watts would be pushing that where it *could* start tripping . . . since i'm of the mind your storage is another 50 watts - 5 NMVE and 2 spinning disks? adding in the 20 watts i mentioned above - it also most lines up with my "rule of thumb", take the max cpu/gpu power draw consumption, add 100 watts for "stuff" and call it a day.

 

[EzioAs]

It's more than enough. Stop over-blowing PSU wattage recommendations please.

I thank you and would then like to take the brisance out of my argumentation to some extent.
I personally would have gone to a maximum of 700 watts in my recommendation, simply for the reason of still having some margin for future newer components without always having the sword of Damocles of the complete revision of all parts hovering over everything.

I have a Seasonic Focus 550w PSU, would that be enough for the 11700 non k? Will just be using on board GPU.

With onboard GPU, heaps of room to spare

well i do not want to put insecurity into this round but i am running a 1200W PSU @82% usage.. what am I DOING WRONG then?

Because you've probably unlocked the TDP's and are chewing hundreds of watts extra for minimal gains.

You could undervolt that GPU without losing performance and lock the CPU to ~125W and find you'll get the same performance under 400W.
(Extra devices like excessive fans, lighting, water pumps etc can all add to that... are you measuring monitors etc as well?)

The only reason I would upgrade, is if you're planning to plug in a high-end graphics card like a 3080 very soon. In typical desktop mode it'll be under 50 watts (whole system) unless you have loads of HDDs and shouldn't ever be much more than 300ish, even with all-core turbo.

no to everything mentioned.
would u help me in another thread to do that? review the watts and undervolt parts to get more efficiency?
we are the world champions in paying our electricity moon-prices here..

i would include your name in my good-night-prayer then for sure!

Yeah go for it man, replies may come in slow but i dont mind helping - once you make the thread send a link to me in a PM and i'll join in.

Try and collect information in advance (wattages, how you're measuring them, CPU and GPU settings, and all the things attached to the system that draw power)

OT:
i used to be a stickler for getting psus that fit like a glove because of low load efficiency. back then gold was the best and <20% load wouldn't get >75%. however today's titanium and esp plats hitting 85%-90% eff. at 10% or lower, sort of takes the wind out of that sail.

75% of peak wattage is what i aim for, but many people mis-calculate what the real world wattages actually are.

BUY A WALL METER! software readings are usually bogus!

I took your advice to heart and adjusted the TDP and the system 8°C cooler in the running state.

thanks already for this

but 4W can't be
View attachment 230810

6 W is just the chipset alone. To that, you add RAM, storage, onboard devices like LAN, audio, USB and other stuff. But these aren't power hogs. I wouldn't expect more than ~20-30 W from them (unless you have something like 10 drives).

when upgraded to my 11700k (worse decision) my PSU 650watt (tried to sold it here as well) was not sufficient anymore. had to buy a new one. the 1200watts. and beside this it does not matter if Gold or Platinum or even higher. and this is my kind of personal proof. my XP i made. and beside this; i trust beQuiet in the fact of suggesting to 50%-80% usage. cus this is even the same with cars. when u hit the gas pedal to more than 120km/h speed the gasoline intake grows exponential. this is not exacly the same with electricity but 550watts is too close to the powerlimit in my opinion.

Just out of curiosity: why was the 11700K a bad decision? You can PM me if you don't want to spam this thread.

As for online wattage calculators, I agree with @looniam - they over-estimate your needs to be 110% safe. They're not built with advanced users in mind. They need to focus on people who are building their first computer as well. I agree that overestimating your PSU isn't gonna kill you, but modern gold and platinum PSUs (like the Seasonic Prime series) have lots of safety margins and endure lots of use and abuse. The days when your 450 W tin box could only deliver ~300 W safely are over, unless you go for a brand with a really low reputation.

The car analogy is valid up to a point. Most consumer cars are built for normal highway speeds - 110-120 km/h or 70 mph. You push them more, and the whole car suffers. The engine isn't powerful enough, the suspension isn't stable enough, etc. However, a good quality modern PSU has no trouble delivering its advertised wattage. You might lose a couple % efficiency, but it won't impact your wallet through your bills as much as buying a higher wattage model would.

And to be honest, when I bought my 550 W Prime Ultra Platinum, nvidia's newest architecture wasn't out yet. What's it called again? Kilowatt? Wait, I've got it... Ampere! Where my assumptions went wrong is when I thought 550 W would always be enough for a top tier consumer CPU and a mid-high tier GPU. The PL-unlocked 11700 and the 2070 is about as high as I'd go now, power-wise.

because the predecessor 10700k took less electricity and was cooler as i experienced. same GHz same (bandwith) same amount of cores

Videos like this are pure clickbait, and should be watched for fun, not to educate oneself in my opinion. Reviewers don't hate Rocket Lake because it's crap, but because it offers nothing extra compared to Comet Lake, as pointed out by @plastiscɧ. Very few people upgrade their systems with every new generation anyway.

As for me, I came from a Ryzen 3 3100 (that I repurposed in my HTPC). Compared to that, the 11700 is awesome (not that the 3100 was bad, but I wanted something with more headroom for the future).

When choosing a CPU, one shouldn't look at the generational improvements within a year, but the improvement compared to the system one is upgrading from.
