My Core i5, RX 480 PC rebooting when starting game, looks like PSU is culprit

Hi everyone
The ones who know me, already know that I was a Rocket League player for whole of 2016 and for most part of 2017 but I stopped playing it since this year completely. So I moved on to other games like racing games and GTA V.

After months of not being able to find time to play, when I tried playing GTA V again last week, I was not able to do so, since as soon as the game loads after a few seconds, PC gets rebooted. This was also for the case while playing Moto GP and Gravel demo. I tried playing Rocket league, and I was able to play it for 10 min without rebooting.

That made no sense, so I started debugging the issue. I tired not limited to, following things:
1. Disk check for errors
2. Updating AMD graphics drivers
3. Downgrading AMD graphics drivers
4. Disabling graphics card completely, during which PC didn't reboot, although game was playing at 15 fps.

At this point I thought maybe it's my GFX. But then why I was able to play Rocket League. So I thought maybe my PC reboots when I attempt to play "demanding games". So I tried:
5. Lowering graphics settings of the game Gravel demo, to low and reducing resolution to 1366x768 down from fHD.

This also didn't prevent my PC to reboot. So I went on the internet to see if others are facing similar issues. I was able to find this page which suggested to install OCCT which is a tool that checks PSU. Computer rebooting while playing games - [Solved] - PC Gaming

6. So I installed the tool OCCT.

The CPU test didn't do anything, except raising temperature of CPU to critical levels. But the GPU test and Power supply test, sure led to my PC being rebooted. As soon as I start the test, PC gets rebooted immediately.

This probably means my PSU is not able to carry sufficient load. Now I have following questions:

1. How suddenly my Corsair CMPSU-430CXV2UK 430 Watts PSU is not able to carry the load, when it use to for years?
2. Is it safe to work on a PC if I don't game?
3. Is there any other test that I can do to "confirm" that it's the PSU?
4. Can it be repaired? Or should I just try to get a new PSU? After all this PSU served me for more than 3 years (can't recall when I bought this PSU exactly).

Specs in signature and also below:

Code:

HP Pavillion 22XW Monitor (1080p)
Cooler Master E350N
WD 1 TB WD Blue
Corsair CMPSU-430CXV2UK 430 Watts
Intel 3.2 GHz 4570 i5 (LGA 1150)
G.Skill DDR3 12 GB RAM
MSI H87M-G43 Mobo
MSI RX 480 4 GB GPU
Samsung 850 EVO 250 GB

First of all you should have used a higher wattage PSU as rx 480 is a power hungry GPU.

probably some deterioration of capacitors as the PSU will be at high load when GPU is stressed. How long have you been using this PSU with your GPU?

2. Is it safe to work on a PC if I don't game?

share the voltage readings from BIOS . Probably the voltage may be dropping more than it is allowed under higher load. If that is the cause , then it may not be a good idea continuing with your PSU.

3. Is there any other test that I can do to "confirm" that it's the PSU?

is it possible to borrow a higher wattage PSU from a friend?

4. Can it be repaired? Or should I just try to get a new PSU? After all this PSU served me for more than 3 years (can't recall when I bought this PSU exactly).

if it is out of warranty, get a new one provided the PSU is the culprit. get atleast a 550W PSU, like corsair tx550m or cx550.

I knew when I bought RX 480 that 430 watt PSU is a bit living on the edge. And it worked too. But now if your capacitor theory is true then yes I will need to get a higher watt PSU.
I bought my GPU on Oct 2016. So using this GPU with PSU for about 20 months.

I will share the voltage readings soon.

I can arrange Antec VP450P 450 Watts PSU from my friend to test. Will report once I test it.

1) Much more chances of it being a PSU problem

Caps have a finite life , given the age and usage of PSU they have likely run their lifetime

2) No on a safe side , although it may appear to be working , failed cap would probably increase ripple quite a bit and affect voltages , that ripple will then be transferred to your caps on motherboard and gpu .. And they would be under stress , thus reducing their lifetime.. Now whether that will signifcantly shorten their life or only marginally will depend how much of it has increased

3) test with other PSU like vp450p from friend you mentioned

4) repair possible- yes .. But PSU uses special types of caps that are hard to find and most local repair guys wouldn't know about it, .. They would just put general cap of same voltage and capacitance .. So it would fail again after a few months while also increasing ripple.. So if you want to recap you will have to use good quality decent brand caps and replace most of them otherwise will be doing the same thing after a few months again , which can get expensive if you order new ones.. Though it can be a permanent fix then

If very tight on budget a new PSU like cx450 @3.2 k is much better with 5 year warranty , if PSU is the cause """test it first with other PSU before buying""""

So I managed to check my PC with my friend's Seasonic 450 watt PSU. I played Gravel demo and also GTA V for half hour. PC didn't reboot at all.

As for voltage readings, here are they in below pic. I can't see much difference, but I think PSU being the culprit is sure now.

Hehe. Bilkul koshish karunga. xD

Created this thread to find the best PSU: Looking for best PSU for my Core i5 4570 and RX 480 PC

Closing this thread as it served the purpose.

Opened this thread again. Since this is weird.

How to make sure that PSU is the actual culprit? Today I was able to play GTA V for 25 min and the PC didn't go restart.

I also tried the OCCT benchmark and PC didn't reboot while previously use to reboot as soon as I hit start the benchmark.

PLEASE HALP.

Hey if some caps are failing, you cant predict when they will work or not. If your PC works 100 % with the new PSU, then obviously the old one is the culprit.
The RX580 was never meant to be run with a CX430v2 anyway, its just barely borderline passes the OK status, get a new PSU (as you have done tests enough to prove it is the culprit) and forget about this business

Don't use that PSU, it might harm the other components too. Just get the new one as you have selected in the other thread.

I think you mean RX 480. Or did you mean RX 580?
Yes I have done the tests. But after that I tested my PC with my friend's PSU. After which now the PC is also working with my old PSU and stress testing is not making my PC reboot. Could that mean that maybe the wires were loose perhaps?

I still want to confirm if the CX 430 v2 is the culprit, cause if it isn't, then surely the reboot problem might arise with new PSU too.
And right now the new PSU is sealed pack and I can resell it if it's not the issue!

It is the culprit. Didn't you test it with your friend's psu?

About last line maybe, maybe not. Perform some more diagnostic tests to be sure. And wait for gta5 and whitestar to chip in.

billubakra said:

I did. The PC ran fine at that time. But isn't it possible that the PC was rebooting because of some loose wire connection? And when I swapped the PSU the issue was resolved?

Not sure what more tests I can perform. The OCCT benchmark isn't failing the PSU anymore.

Again maybe. Can you test this PSU in some other system and perform a test in that system?

billubakra said:

It's difficult to replicate the issue in another system since it would only work if it's on heavy load.
I would rather test my own system with some other PSU, which I already did and PC didn't reboot when I did.

I think the issue is resolved temporarily and it will resurface again. I just need to do some tests, which I am not of right now.

Did you take into account UPS in these tests?I mean do tests with your old psu with/without UPS or with fully charged/partially charged UPS batteries.If caps are the issue then there are more chances of psu issue coming up during powercut/resume when switchover happens between mains & UPS power.

Umm no. I didn't take into account UPS. But I could easily replicate the PC being shutdown as a direct result of starting the OCCT benchmark. Now though no matter how much I game, how much I run the OCCT benchmark, my PC seems to be working A-ok.

I also just placed an hour of Crew 2 (open beta) on Ultra settings. No reboot. I think my PC trolled me hard af. -__-

Any up to buy a sealed packed TX650M?

If the issue is because of caps , then electrolytic caps do have self healing properties..

I DON'T suggest to use that old PSU and game on that.. And NOT to experiment with it trying to put load on it to see if it is working or not..

Your old PSU even though appear to be working , may not have lot of life as it is So your new investment isn't waste .. And we can only guess about what kind of ripple it is outputting..

Use the new PSU ,

If the issue doesn't appear again after a month with new PSU then you can be pretty sure it was related to old PSU..

Damn, you are scaring me.
Alright, I think I will use my new PSU and put the CX430V2 idle, possibly to be used with some secondary PC.

Once I install the TX650 I am planning to open the CX430V2 and to see if there any physical signs of aging of the caps. I know the caps can have charge and I may get an electric shock, but I can be careful.

Not worth it.

Keep CX430V2 as backup/secondary pc usage.In my experience it pays to have a secondary psu around even if just for testing purposes.

Takiakalaam of @billubakra

So, I finally upgraded my PC from CX430 V2 to TX 650M. And I can feel my PC is happy. (Why wouldn't it?).

Here are some pics (from album: Installing Corsair TX 650M)

Please don't mind the cable management. I just zip-tied all the cables in top corner.

I got a wire of these pins (I think EU version), so I would need to use a converter. So right now I had to use the old power cable.
My question is that the new plug says it's 13A 250V, while the old power cable said 7A, 250V. So is old cable bad for this new PSU?

*i.imgur.com/jXiThvX.jpg

Also these two 4-Pin 12V CPU cable is joined in a strange way. I can't separate the two cables, since I only needed one 4-pin 12V CPU cable.

*i.imgur.com/zTDs7Qo.jpg

Thanks everyone for the help. Now I will see if my PC reboots again or not.

Next purchase : Cabinet

Waiting for that excel sheet, cuz I might need it too

While I would like a new cabinet I don't think I "need" it right now.
Maybe when I make a new PC with water cooler and dual GFX and LEDs.

Nah man, dual GPU, water cooling and LEDs are all gimmicks, even I planned to do all that with my PC, but ended up not doing it because its just useless. Would rather spend the money on storage etc. My PC isnt a looker just like yours

I would rather spend money on safety (like PSU), and performance like SSD and graphics (like GFX) , then make it look all flashy. xD

Look at cpu cable connector carefully there should be a fine line there. You should be able to split apart the connector(only upto the cable) along that line.

I ain't opening my cabinet until I need to clean it up, or until another issue crops up.

Thanks all of you folks here. One more issue can be closed in the books. (For now atleast).

^^So how did you connect it without splitting it apart.

I think there's some miscommunication. I didn't have any problem connecting one of the 4 pin. Cause they can be split.
I was saying that two 4 pin 'cables' are joined in a very strange way, such that it's not easy to take one apart from one, thereby negatively impacting cable management. Look at the image again.

Two wires from each 4 lane cable are splitted into both 4 pin plugs.

Pls change the cabinet too if you can. Top psu is never a good idea.

Dust. If I drill holes in cabinet, I would be inviting more dust. So no thanks. I am ok until I can afford a good case with proper vents and filters and ability to install fans properly.

It's an intake fan. It will intake the hot air from the other components and exhaust it from back. If it is placed in the bottom with a bottom vent it will intake cold air from bottom and its cooling will function completely isolated from the rest of the PC. Other than cooling the weight of the PSU is a problem if top mounted.

How is this PSU's weight compared to CX?

I see,in latest CX series this cable is not like TX series & you can only split apart the connector portion so if you connect the one 4pin plug the other 4 pin plug will be just at its side with no separation in cable at all(as it is in yours TX model).

It was like that in my CX series CX430V2. But in TX650M, a modular PSU, I wasn't expecting that in this.
