Please help

hey guys currently own 5700xt and 550w psu, under load this gpu will draw alot of power in the form of a spike.. This has caused my system to reboot in game menus and whilst gaming over and over again until i finally decided to undervolt my gpu which has fixed all my issues until i get a new psu. Manufactures give these numbers for a reason

What is the PSU?

corsair cv550

Those recommendations exist because of people like you cheaping out and getting a crappy PSU. There is more to a PSU than just the wattage.

nice to know that the CV550 might have such issues, tho fairly odd considering its really just a VS550 upgraded to bronze. 

 

if you have the option if return it, but its one of the better group regulated units. id just suggest getting a non group regulated unit within 5 years-ish.

I don't think the psu is the issue, i believe that the 5700xt spikes in power momentarily which simply is too much for 550w psu to handle.. these gpus are very power hungry especially when clocked up, this is why de-volting has fixed my issue for now

they are actually fairly tame power wise. offcourse there are spikes, but unless the PSU is perticularly sensetive to transiens it shouldnt care. 

 

we saw this with other PSUs like the seasonic focus fx pre-2019

 

still doesnt change the latter statement.

Sorry, what? 
 

You had complete control over what parts you put in your system, yet get offended when someone criticizes you? 
 

You need to work on budgeting pal, pairing a $40 PSU with a $400 GPU isn’t a good idea.

If your system did draw ~700wDC or so (your PSU is rated for continuous load) to trip off the Over Power Protection of the power supply, the unit will stop supplying power to your system. Since it is restarting, then this isn't an issue with your system needing more than 550w, but rather a stability issue (assuming that it is cause by your PSU) cause by your PSU choice being not ideal for your rig (you should have gotten something along the likes of RM550x or TX550M). If a new power supply fixes your problem, it is because you got a better PSU.

Yes, manufacturers will recommend certain numbers for a reason, and part of that will also include liability. They can't make recommendation based on the bare minimum. The recommendation they provide needs to factor a wide range of system configuration and power supplies. Power draw of a system with an i3 vs one with an i9. Or a PSU rated for 550w peak with a 12V rating of 30A or a 450w continuous rated PSU with a 12V @ 37.5A.

 

Look at this GTX 780: https://www.evga.com/products/specs/gpu.aspx?pn=3b81d7e2-830d-43cc-8fee-d15f2ab43767

"600 Watt or greater power supply with a minimum of 42 Amp on the +12 volt rail."

A high-end PSU like the Seasonic Prime Fanless 500w has that 12V rating. I'd power that on my Rosewill Capstone 450w for a few years before giving it away.

 

One example where a system is being power by a PSU that's lower than what is recommended by the manufacturer, this Northwest Falcon Tiki had an i7-3770k OCed @ 4.6GHz and a GTX Titan power on a Silverstone ST45SF-G 450w. The Kepler-based GTX Titan is recommended to be power on a 600w by nvidia. Before someone says something, yes. Your mileage may varied depending on your overclocking goals: air, custom water-loop, or DICE or LN2.

This can depend on the third party variant, i don't exactly but i have read that they can reach almost 300w.. which is a good chunk of a 550w psu.. Adding in cpu at high load surely just pushes it to far??

Looking at the replies here (excluding the ones that were removed), everyone seems to have explained to you what the culprit most likely is here, and why. 

I don't know what @gloop said that you found so offensive that it warranted the good ole "get a life" comment, but if it was something along the lines he said in a later reply about pairing a $40 PSU with a $400 GPU, I really don't see the problem. 

People on here and other tech forums will try to help you out, that is if they can and if they want to, and senselessly throwing insults around really isn't going to benefit the "if they want to" factor.

 

Just to clarify, I also agree that the CV550 you've got is most likely the problem here. Not because of the wattage (assuming you're not running a Threadripper or who knows what super power hungry CPU), but because it's a unit that's mostly meant to power office, low-power builds. A build with a 5700XT is exactly not that.

The higher transient spikes of your GPU are most likely triggering the OCP of your power supply since, again, the CV550 you have was never meant to be paired with GPUs like your 5700XT.

yes you are correct, i came here to learn and hopefully teach what little i know to other people like me. my first comment was probably an issue you see all the time so gloop response was some what warranted. 

 

i had no idea that cv550 was office orientated, im not rich so this psu after reading some comments online stating 550w is enough and that was it.. made sense at the time and it will be replaced by something far better very soon

nope, unless its perticularly high transiense shouldnt cause such issues. 

 

which Vega and the Strix 970 are examples of such GPUs, but RDNA is pretty tame. could just be a transiense sensetive CV550, tho that would be the first report ive ever heard.

well its more that its topology isnt suited for crossloads or higher current scenarios due to it being group regulated due to lacking UVP and not great voltage regulation (due to being a group reg)
