PSU expert required - Is my PSU good enough still?

[dirtyferret]

before you pick and choose something off a web site to link and try to support your argument you should carry over the entire article

And the difference to 99% of people between a 30 or 50c psu rating isnt even noticeable.

from your own link

How does the temperature inside of my case affect the performance of my power supply?

Power supplies can perform differently depending on the temperature at which they are operating at. When a power supply is rated for it's total output wattage, it is rated to do so at a particular temperature. Anything beyond this temperature may take away from the power supply's capability. A power supply that is rated to put out 550W at 25°C or 30°C (room temperature) may only be able to put out 75% of that at 40°C or 50°C (actual operating temperature). This difference is called the "de-rating curve". A normal operating temperature for a power supply is 40°C.

If your gnd-tech web site reviewer understood this he wouldn't be "reviewing" PSU at room temp but rather a hot box like Aris does and you may want to check out Aris test equipment and compare it to the gnd-tech test equipment.

FYI, Jon's comments on MTBF is independent of operating temp rating and he even says so in his opening sentence.

Unfortunately, no. It's a tough race out there and there are a lot of guys rating their PSU's MTBF (MTBF temp) at room temperature, even if they rate their PSU at operating temperature (operating temp).

You must just have something against evga. Or just something against me. Idk. But Youre running a 650w psu with a 9700k and a 1660 ti and youre telling this guy that a 650w for a 3070 and a 3700x is more than enough. Not hardly. especially when you add all other components to it.

I have nothing against evga, in fact I think they do a good job on their customer service front and find their PSU to often be price competitive with the market.

But Youre running a 650w psu with a 9700k and a 1660 ti

What I have is independent of anything and I don't push what I have to other people. I purchase what I have because it meets my needs and I keep my options open so I can get good parts at a good price.

youre telling this guy that a 650w for a 3070 and a 3700x is more than enough

What I'm telling "this guy" (the OP) is if his unit works fine and he doesn't want to purchase another unit than the answer to his question of "Is it OK to use my PSU?", the answer is yes.

Or just something against me....is more than enough. Not hardly. especially when you add all other components to it.

1 - I have nothing against you. I don't know you, you just stared here a week ago. I'm trying to separate fact from hyperbole opinion.
2 - I did not say it's more than enough, I said it will do & work with all the "other components" included. That is a fact, it's up to the OP if that is enough for him or if he want to purchase another PSU.

The Seasonic M12II-620 is getting some age on it. It's got to be 10 years old.

What a interesting discussing is going on here. Really appreciate you thoughts, gentlemen.

So little bit of additional input from my end:
1. I do not have any peripheral except of Sennheiser USB headphones, LED keyboad and not that modern USB mouse. I even do not have the SATA drives, only two m.2's. But three 120mm fans and beefy tower cooler. Ah, the Intel Wi-Fi 6 PCI-E card. Not that much I suppose.
2. I tend to play games once or two per week (and not every week) so my 3070 primarily is being used in some lightweight computer graphics pet project or for the netflix.
3. I do not have any critical info on the PC.

So I would go with dirtyferret suggestion - leave the PSU for a while since it is enough assuming the current workload.
Despite this I truly find vision of nuggdoctor as to be valuable because if I had been loading the system from day to day I would have upgraded the PSU because of sake of complicity and calm of myself.

Thank you all

I guess your system can live with however much juice it can get, if the psu works fine, so be it...

 

[Mussels]

At max his set up would hit 350w gaming, I don't think "cutting it close" means what you think it means

^ This. the wattage is not an issue.

It's an older PSU and newer designs exist, sure. But unless you get crashes or shutdowns because its failing, i really wouldnt worry about it. The 3070 is not a power hog like the 3090 or 3090

My 8700k and gpu pull 372.66 watts under firestrike load by themselves. then add the rest of the internal pc components and usb attachments and youre easily at 600 watts or more. And unless its going into a tiny micro atx build the heat from the 850BQ is minimal. ive had no issues with mine and my temps are very low even under load. The 850BQ is rated to+40c Max https://gnd-tech.com/2018/08/evga-850-bq-power-supply-psu-review/

A question to answer please...
How are you measuring that your CPU+GPU = 372W without the other internal components?

Hi

Currently the PSU supplies next: R7 3700X/X470/16 Gb 3333MHz/RTX 3070 OC/2x M.2
The PSU is - Seasonic M12II-620 Evo Bronze.
https://seasonic.com/m12ii-evo

It goes pretty smooth as far I can see/feel. The PC is little bit more than year old.
Also worth to mention, the beefy 5700XT has been working for a year before I got the 3070 one.

The gaming and home pet projects are the main objectives running on the PC.

My current question is - is it ok to run given system at so outdated PSU, especially if it has Bronze certification?
Btw, I heard despite this one is Bronze it has decent electronic design and capacitors from Gold PSUs... As well as opposite thoughts

Do I have to update it to something more modern? If yes - what it could be?

P.S. One point is bothering me that I could not get my system running stable based on 1usmus' CTR recommendations despite my CPU is silver rated... Starting to assume the PSU could be a reason...

I would glad to hear any thoughts...

Your system can’t pass 400W under gaming. Maybe on very short bursts but this doesnt matter. It should avg around 350-370W. Your PSU is fine. Not be able to run CTR OC has nothing to do with the PSU. Its the CPU that can’t eventually run the suggested settings of CTR.

You can do this...
Get HWiNFO64, open sensors mode window, leave it minimized and play games or run what ever heavy load you have. After you done, check on HWiNFO for the PSU main voltage rails. +12V, +5V, +3.3V. You can see current, min, max and avg values.

Don’t use unrealistic and abusive stress tests like furmark, just your every day usage. If you’re not gaming you can have it right next to you software and watch the values live.

As a PSU made by a reputable vendor, at the very worst it will just kill itself off permanently without harming the rest of the PC.

I don't see any downsides sticking with the old.

Do not put trust that this will happen this way, a psu failure is unpredictable, it can damage all your components

Bro chill out it's not a hijack... He clearly has enough response and i'm not sure how to make a new post.

if you use cpuid hw monitor you can break down your power consumption based on the component. Run it while you run heaven or cinebench or in my case 3dmark benchmarks and it will tell you your minimum average and max power consumptions for your pc. since it shows cpu and gpu power usage it makes it easy to see what your system is using. but it doesnt show fans and peripherals or rgb etc. https://www.cpuid.com/softwares/hwmonitor.html

 

[Zach_01]

I prefer this:

UnigineHeaven4.0 (10min)



CPU: 50W (avg)
GPU: 210W (avg)
Rest: 100W (avg)

=360W avg (380W peak)

On real demanding games the values are similar, 350~380W avg (370~410W peak) depending the game.

OP's system is very similar with 3700X+3070
A 650W is more than enough yes.

Dont compare it with your OCed 8700K system, it has nothing to do with it.

But I'm trying to downvolt not overclock the CPU with the help of CTR or without. Neither does not work. For instance I've been playing CP'77 on to gentle 1.3V Vcore instead of default 1.4+V. Everyting was ok, but once I quit in next minutes the PC reboots with BSOD. Or somewhere at midnight when the PC is sleeping.

Btw, following your advice I have logged the Vcore with hwinfo - so suspicious 1.276V instead has been tracked with 1.3V set in BIOS (LLC == 4). So, I stopped tracking and in next minute the PC rebooted.

Who does fail - PSU or CPU?...

I said monitor the +12V, +5V and +3.3V rails under gaming or other heavy load you may use for your tasks to see if any of them fluctuates more than it should. It’s an indication of good/bad PSU condition.

Static speeds and voltages on a Zen2 CPU is a complicated matter. Do you have any crashes or reboots if CPU is at stock settings with just PBO enabled/manual settings?
I wouldn’t recommend going over 1.25V (vcore SVI2 TFN) for static voltage to any given speed. Your CPU could just can’t sustain the chosen speed/voltage. It’s very common that CTRs suggestion won’t work. It’s just a guide and not a bible.
Also not all CPUs are created equal. Some have plenty room of undervolting than others, even comparing same SKUs as 3700X vs 3700X.

Do not be afraid of 1.45-1.5V over stock boosting. The CPU “knows” what’s best for it self, even when boards are giving it false feedback for its power and/or current.
All Zen2/3 CPUs are hitting 1.45-1.5V on stock boosting. But that’s under light loads with low current.
Run a CB R20 all core bench with stock settings and you will see a vcore (SVI2 TFN) way less than 1.4V.

What a brilliant suggestion here. So I abandon my downvolt idea and leave the things as is!

Thank you!

 

[Zach_01]

Or you keep 1.25V actual static, and find a speed that can hold that voltage without crashing...
