PSU problem

[Jckxlsxcldlsnxnfk]

Hi everyone, i built my pc yesterday, but after installing cs:go i tried to play it for a while when suddenly my pc turned off. No BSOD or anything else, it just turned off randomly while playing. I think it's the power supply since it's an Amazon wharehouse product, and it might have been given back because it has some kind of problem, but I'm not really sure what to do to verify that

My pc specs are

Ssd: 1tb crucial sata
Motherboard: msi x470 gaming plus max
Gpu: rtx 2070 msi gaming z
Cpu: ryzen 5 3600
Ram: crucial ballistix 3600mhz CL16
Psu: sharkoon WPM gold zero 750w 80+ gold
Os: windows 10 pro

Has this happened repeatedly or only once? Do you have any other PSU you could use to swap & test out if the problem really is from the PSU?

 

[Jckxlsxcldlsnxnfk]

It happened twice today, and no, unluckily i don't have another PSU,but at this point i think I'll give back the PSU and buy it again hoping it will work

it's a C-tier PSU.
I'd recommend you to just return it if possible and purchase a better one instead.

Yeah power supply if it a few years and less then 450w it not efficient enough for that set up best bump it up to 550w if stock no overclocking. If overclocking is been used best to bring it up about 650w to 850w. Best go for branded power supplies like antec, evga, corsair name a few but not Chinese branded as you be asking for trouble if the power supply decided to take out other components

Yes, I recommend that you trade that in for a well known PSU brand manufacturer with at least 650 Watts (ideally 750+ Watts) with at least Bronze rating for your rig. I think Sharkoon is a Chinese or Taiwanese brand which makes it suspicious especially since they don't have stable continuous wattage rates & I'm sure the Gold rating that they applied is bogus.

 

[Jckxlsxcldlsnxnfk]

Yeah i think I'll go with a well known 650w (I think 650 is still enough for this build)PSU at this point, thanks you all for the suggestions!

(I think 650 is still enough for this build)

When it comes to selecting a power supply, it is silly to guess and pick arbitrary numbers out of thin air!

"If" it is less than 450W? The OP said it was a 750W supply.

Instead of guessing, research all your components to determine their power needs. Add them all up to calculate the size PSU you need. Add a little headroom for future upgrades, then buy accordingly.

OR...

Use a good PSU calculator. The only one I use and recommend is the eXtreme OuterVision PSU Calculator. This will calculate your minimum needs and recommend a suitable size for those needs. Plug in all your current components. Be sure to plan ahead and include all the hardware you think you might add in 2 or 3 years (extra drives, bigger or second video card, more RAM, etc.).

As seen here, you could easily get by now with 450W quality supply. 550W would probably be a wise choice unless you are planning on upgrading both your CPU and your GPU in the near future. 650W is moving into overkill region. 750W is overkill!

Note I had to guess on what to enter because you did not provide your full system specs. We don't know what kind or how many drives, for example. Or how many case fans or sticks of RAM. So I added some and a Blu-Ray drive too.

I do agree with Rei and you need to swap in a known good spare to see what happens. While waiting for your replacements, see if you can borrow one from a trusting friend or relative.

Your problem might not be power related.

Well Bill Bright at the end of the day 750w or 850w isn't exactly overkill as you are forgetting the efficiency curve that exist in current power supply based on properly approved ratings. Since I already did my own testing based on antec hcg850m 850w with a watt-meter on my current system it only pulling less than 285w peak total system power. And my reason of 850w is for further future proofing for upgradeiblity down the road. 450w isnt the norm anymore due to the latest and greatest component requiring more wattage that why you need to read the correct requirement than undercutting for crap Chinese knock off that has a high enough chance blowing component

 

[John Naylor]

What does Event View say was the cause of the shutdown ? Without that answer, best answer you can get is mere speculation

450w isnt the norm anymore due to the latest and greatest component requiring more wattage that why you need to read the correct requirement than undercutting for crap Chinese knock off that has a high enough chance blowing component

450 watt never was the "norm" ... at least not in this millenium, but if you haven't noticed, PC componentry is getting more and more efficient with each generation.

Sharkoon WPM PSUs are manufactured by CWT, the the 750 Gold is not in the database. CWT makes PSUs for many popular brands (i.e Antec, Corsair including part of the HX Series, most of the TX series)

Well Bill Bright at the end of the day 750w or 850w isn't exactly overkill as you are forgetting the efficiency curve that exist in current power supply based on properly approved ratings.

Sorry, but I am not forgetting anything. And sorry, but it is clear you don't understand how power supplies work. That is not a criticism, just an observation as most who have never had formal electronics training don't have a good grasp of these concepts.

It does not matter how efficient the PSU is! If the computer components need 250W, that is what the supply will give it, regardless if the supply is 90% efficient or 70% efficient, 450W or 1000W.

PSU efficiency dictates only the following:

1. How much power the PSU pulls from the wall,​

and​

2. How much power is wasted in the form of heat.​

PSU power ratings are based on PSU output.

And did you note I said "quality" 450W supply? And if you want to talk about efficiency curves, we can. The very purpose for selecting 80 PLUS certified PSUs is to ensure the supply provides a "flat" efficiency curve of at least 80% across the full range of expected loads from 20% load all the way up to 100% load (down to 10% load for Titanium). But a non-80 PLUS, cheap supply will likely have a "bell" shaped curve with a single peak at ~50 - 70% load. But again, that has NOTHING to do with the output or power supplied to the connected components. That only affects the power pulled from the wall and energy wasted in the form of heat.

And just to avoid any further confusion, I am NOT suggesting 80 PLUS implies a "quality" supply. It does not. This is because 80 PLUS certification criteria do not ensure quality regulation, superior ripple suppression, or tighter tolerances to the required 12V, 5V or 3.3V DC output voltages. A high, "flat" efficiency curve is but characteristic of a quality computer PSU.

@Bill_Bright Well i know and understand power supply I only said less wattage isnt the way forward as i have read and studied alot of component power requirement as talking about efficiently i saw and read power consumption keeps on increasing either stock or overclocked configuration due to intel and amd increasing cores and threads along with rtx series as 450 watt isnt going to cut it if there is more ssd/hdds, rgb lighing, fans, pumps that alot to put on the 450 watt psu.

I give you a prime example as a friend of mine got amd ryzen 3600, 2x8gb corsair ram, 1tb hard drive, msi b450 board, 2 fans, nvidia gtx1660 and no rgb lighting all that on the corsair cx450 psu and what happened after that computer kept shutting down he had to swap the brand new 450 psu for 550w psu because he has being reading misleading solution giving by people who dont know what they are saying

 

[Bill_Bright]

Well i know and understand power supply I only said less wattage isnt the way forward

No. That is not what you "only" said. You said that 750 - 850W is not overkill because of the efficiency curve. The OP has a Gold supply. Your Antec hcg850m 850w is a Gold supply. Therefore, they have relatively flat efficiency curves and because they are "Gold", efficiency ratings of at least 87%.

Now you keep adding more "If" statements in your attempt to justify your previous incorrect claims. Nobody is talking about adding more drives, lights, fans, or pumps to a 450W supply. Again, the OP doesn't even have, and has not indicated he is even considering a 450W supply. I never said he should get 450W. I noted that 450W would work but my recommendation was 550W.

As far as your anecdotal, sample size of one example, your friends problem was more likely due to using an entry level CX450 supply. Regardless, until Man can create perfection 100% of the time, even the best models from the best makers can have a unit that does not meet specs. If you do the research and then do the math instead of just arbitrarily pulling numbers out of nowhere, you would see a quality 450W supply is more than enough for your friends computer, especially with that GTX1660 graphics solution.

Anecdotal Proof

Note I did not suggest overkill is bad. No harm is done by buying way more power than you need (except may to your wallet). And for sure, if someone will be upgrading in the foreseeable future to a hungrier GPU and/or CPU, they should buy a PSU with plenty of headroom to support that. But to arbitrarily buy much bigger than needed just does not make good fiscal sense.

Those are just the "facts".

In terms of my personal "opinion", I would never buy "way more" than I need for the intent of future proofing beyond a couple (2, 3 at the most) years. Why? Because in 4 or 5 years "IF" I will be upgrading to a power hungry graphics card, I am going to get a new PSU anyway. But that's me.

 

[Edwired]

Well everyone have their own opinions what they want to get the psu with their own money. I'm not here to judge anyone at all as I only said it for the sake of upgradability in the future as well have the headroom if overclocking or adding extra components.
The power supply i have is this one https://www.techpowerup.com/review/antec-hcg-850m/6.html
Had it for the last 5 years since new as it was an exdisplay only paid €120. Never had any issue with it

 

[Bill_Bright]

And that's great. Glad your Antec has served you well. I used to use Antec supplies (and cases) exclusively because of their build quality, conservative design and reliability.

And you are right, that opinions differ and that is fine too. But as suggested in my sig, we are entitled to our own opinions but not our own facts. And frankly, it is my opinion that our opinions should be based on fact - at least when it comes to electronics which are governed by the laws of physics and not opinions.

 

[Jckxlsxcldlsnxnfk]

First of all, thanks a lot for your messages, they're really helpful since I'm still a tech rookie. I know 750w is kind of an overkill, but i didn't make the choice to go with that wattage because of the efficency curve, i did it because i was planning to make this build as upgradable as possible, and seeing the wattage requirements on new graphic cards I decided to go with a 750w. I know some people (like you said) prefer to change the PSU directly if they upgrade to something more power hungry, but for the moment I just find that overkill. I don't think a power supply is going to die in 2/3 years so I don't find it optimal to buy a 450w PSU and change it to a 750/850w in some years, when I could have bought a 750w to begin with, but that's just my rookie's opinion and I could definitely be wrong. Anyway I'm now buying a new PSU to verify if that's what's actually causing the issue (I have no other way to find out) and I'll let you know when I'll test the new one.

 

[Bill_Bright]

Again, that depends on how old the supply is too. If you are planning on upgrading in the next 2 or 3 years, it makes sense to buy a PSU today that will meet your future needs. But because everything inside the computer case depends on good, clean, stable power, if it ends up being 5 or 6 years before upgrading, I most likely would budget for and buy a new PSU too. But that's me.

That system is similar to mine except the GPU. 2070 uses a little less power than 5700XT.
My system on demanding gaming typically uses 350W avg with peaks around 400W.
So a nice quality 550~650W Gold PSU will be fine. 550W if it’s going to be kept for years as it is. 650W if an upgrade is ahead(higher CPU/GPU).
