PSU causing lag?

[tiopaco]

So I have been experiencing lag in games after a few minutes of playing, even playing non demanding games like Skyrim and Borderlands. I tried everything, reseating CPU, swapping GPU, swapping ram, fresh install etc, it is also not a throttling problem because my temps all seem stable. But, a friend of mine mentioned to me the other day that it could be my power supply not outputting enough for my system. I currently have a 450W EVGA PSU powering a Ryzen 5 1400 on a ASUS Prime A320M-A, and a MSI Armor RX580 OC edition. Could it be my power supply? Would a 500W PSU possibly fix my issue? If so, what PSU would you recommend? 

 

Thank you in advance

It may very well be your PSU but more info is needed. Are you overclocking your CPU/GPU at all? In addition, are you gaming in an environment  that is around 20-30 Degrees Celsius?

It can happen . But it's such an edge case that i wouldn't even consider it.  Even though , 450W is plenty for that rig .

 

Although , to note is that when this happens , it's not because  of the power supply capacity .

Not officially.

 

AMD recommends a minimum of a 500w PSU for RX 480 and RX 580 rigs

 

It's on the box.

I would recommend replacing the PSU with a 600w Unit just to be safe.

We both now that the 500w figure is to prevent people from using POS units with barely enough capacity.

He's using an r5 1400 , that going to use 50-70 W max . I know the 580 is power hungry , but it's NOT going to use 350W+ .

 

Despite that though , it would just hit the OCP if capacity wasn't good enough

Its not the PSU, 90% sure of that.

 

R5  1400 at stock only uses ~50w and RX 580 uses ~200w max.  Even a relatively cheap 400w PSU should be able to handle that.  If you were maxing your PSU out, the system would shut off.

 

What are your full system specs?

That figure is so inflated that is almost meaningless. I have been running a more power hungry righ (R5 1600 + RX 580) on a 450W PSU without issues for over a year.

Thank you to all, I'm gonna buy a new psu just in case and for the sake of future upgradability. Is the EVGA Supernova G3 650W any good?

I would get a better motherboard with that money honestly, that will give you better future upgrade potential than a larger PSU.

 

A320 boards cant really run Ryzen 7 cpus very well because of the bad power delivery design.
