Is the PSU dead?

[WereCat]

I have PC right there and it doesent want to start at all. I triet to start it by shorting contacts on the MoBo as well but nothing happens.

I am going to try to throw the GPU in my main PC to see if at least that will work but may the PSU be bad or the MoBo is bad?

 

PSU: Corsair CX500

MoBo: Gigabyte FM2+ A88XM-DS2

 

Also do I have to take out my GPU or can I just throw this one into another PCI-e and just disconnect PCI-e cables from my main GPU?

Stupid questions first: All the necessary power connectors are plugged in and the switch on the PSU is flicked to the ON position?

 

You can try if the PSu works by shorting the green pin on the 24 pin header with any black pin on that header and flicking the switch. If the fan turns on -> the PSU is good.

Yes. I checked if everything is plugged correctly. I will try that thing with 24pin.

@KamiKatze nope.. Nothing hapoened when I shorted the green cable with black one on the PSU 24pin

OK. So now I know for sure that PSU is dead. I took that PC apart and tested the GPU in my PC and it works great so I am assuming everything else is fine as well but I will make sure over the weekend as I dont have much time this week to test all of that.

Anyway this guy want this PC sell it to me for €150 and he claimed everything worked. I planed on reseling it for profit however it is a lot easier to sell entire build than individual parts and now if I dont know I will be able to sell it like that.

The specs are:

CPU: Athlon 760k

GPU: R9 270 (Gigabyte Windforce 2-fan cooler)

RAM: 2x4GB ADATA XPG DDR3

CPU Cooler: stock

MoBo: Gigabyte FM2+ A88XM-DS2

HDD: 1TB Seagate Barracuda

Case: Tracer (who know which one.. but it looks decent and there are 2 fans included)

 

PSU: Corsair CX 500W (faulty).

These specs are not bad for 150€. One might assume that the price is that low because it is broken.

 

Try to source a second PSU to test the thing. It's the only way to make sure the motherboard etc. is working.

 

Report back if you find out more.

Yea sure Thats what I have in plan. I want to use PSU that is in my main PC but the problem is that my CPU cooler is huge and it is blocking access to some cables and I will have to remove it along with the GPU and it is pain in the ass to mount it back (be quiet! Dark Rock Pro 2 CPU cooler) so I am letting that be for the weekend as I have work now (afternoon shift).

I know the pain of plugging cables behind a bequiet cooler. If you don't have any other possibilities to source a PSU, then i think sadly its the only way to go.

 

Nevertheless, it would be a great buy if all the other parts worked fine. You'd just have to buy a new PSU (50 bucks), do some performance testing on the PC and you can probably sell it for $300.

So looks like the PC is working.

 

 

But before I disasembled my PC I tried it with borrowed PSU. I have never seen such thing. I was affraid to plug it in in anything but I did anyway. And guess what? Nothing exploded But nothing worked either .

 

 

I guess it was combination of laying in the cellar doing nothing for several years + unsufficient connectivity and wattage (since it has only 20pin + 12V ATX 4pin instead of needed 24pin and 12V ATX 8pin).

 

EDIT:

However the CPU idles at 60*C and in load it is up to 95*C and higher. I am assuming it is the CPU cooler because I tried to change thermal paste and clean it but no matter how much I tried there was such a black gunk in the bottom of the stock CPU cooler contact plate and I was unable to clean it off even with alcohol. Everytime I wiped it I was left with black mess on the towel. No idea what it is.

 

EDIT2:

However I was taking readings from CPUID Hardware Monitor which was giving A LOT of strange results so I dont know if the temp readings were true. It was also claiming my PSU lanes are a lot bellow what they should be. 12V lane was at 8V, 5V lane was at 3V and 3.3V lane was at 1.8V. But it does show correct readings with my PC so I have no idea whats up with that.

(It showed only Package temps and it didnt showed up any core temps).

 

EDIT3:

Also the CPU fan while in load didnt sounded like jet engine so I am assuming the temps were in OK state because I think it would max aut the fan trying to provide better cooling if the temps were in fact so high.

That PSU looks sketchy as hell, haha.

 

You could try scratching the thermal goop off with a knife or a razor blade. I mean, fuck the stock cooler, i would have no respect for that thing. But its good to see that the thing works at all. Does the CPU boost to its max frequency at least?

Yes in Unigine Valley it does boost to 4.0GHz-4.1GHz but I tried to run OCCT stress test and I had to restart computer as I launched it before I launched CPU-Z and then PC laged so much that I was unable to turn the stress test OFF. So I guess it throttled like hell. Even mouse cursor was simulating slide show.

Yea it is good idea to scrap it off with knife I just did not wanted to mess with it too much, also I have almost no thermal paste left and I was not sure if I will need that when I was assembling my PC back.
