What is the Risk with These 2 Used Power Supplies?

Recommended Posts

Posted · Original PosterOP

Hello professionals.

 

Right now I need to test if my motherboard powers on with other PSUs. I didn't feel like purchasing new power supply just to see if my motherboard works so I found someone on Facebook who gave away his 2 power supplies that he doesn't know if they even work.

 

Both power supplies don't have 4/4+2 connectors for my graphics card and I don't really care about that because all I need is to make sure my motherboard powers on i.e. SYS_FAN and CPU_FAN spin.

 

Here's first power supply. It doesn't have I/O back switch but it's not a big deal:

Here's a second more sexier power supply:

Here's how it looks from behind:

I am going to use paperclip to turn each power supply on. Seeing their fans work, I am going to test their 24-pin cables for nominal voltages. Should I also test 4-pin CPU cord?

 

Now on serious note, how high is risk for these power supplies to damage motherboard?

 

My system specs:

 

CPU: AMD Ryzen 5 3600X

Motherboard: Gigabyte B450 Aorus Elite 

GPU: EVGA GeForce RTX 2060

RAM: 2x8GB Corsair Vengeance LPX 3200MHz 

Original Power Supply: Corsair TX650M

"What is the risk?"

 

Yes

 

 

edit: honestly, scale up PSU quality with your system tier

yours is a mid tier PC and it deserves a tier B PSU

Yeah, I will get rid of second rusty power supply. Huntkey power supply is not rusty though.

umm I don't think 350watts will power the system

Well.. let's see.

 

One of them is just going to blow up and kill all of your PC hardware.

 

The other one will shoot flames and burn down your house.

So if I do paperclip test and multimeter test with first power supply and voltage will be good, do I still run the risk of damaging my hardware?

there's probably bad safety on these things, so they could literally kill your entire PC if something in there is bad (judging from the rust, high chance)

 

i would advice against it, and 350W (if these can even deliver it) is barely enough for your rig

 

dont forget to quote/mention when replying so we'll see it

250W sustained is not enough, assuming it can deliver 250W

@Moonzy There are 3 options for me left:

 

1. Buy used PSU of known brand which works

2. Buy generic $25 PSU from PC repair shop

3. Spend $150 on a new branded PSU

 

I really prefer one of first 2 options. All I need is to test motherboard.

OR...

 

Take the MB into the PC repair shop that you would go into anyway to get the used PSU and let them test it....

 

Would take about 5 mins for them to see if it works and you lose nothing and buy nothing you don't need.

Thanks. I had never seen a power supply with syphillis before. 

That Sun Pro is ancient. Still has -5V which has been obsolete for what, 20 years? Max 9A on the "12V" rail (probably really "anywhere between 10-15V rail")

PCIe power cables (for the graphics card) are either 6 pin or 8 pin.

So, you PC isn't running at all then currently?

Kill them both with fire before the first one kills your motherboard with fire and the second one kills you with fire.

Okay, I will describe anomaly that nobody solved until now.

 

Recently I have left my computer unused for a few days, maybe 1 week. When I tried to power it on it didn't. I took motherboard, CPU, RAM and power supply out of chassis to try to understand what is wrong.

 

I started with power supply. Used paperclip to connect green and black and saw that fan was spinning. Then I took cheap multimeter I purchased from Chinese website and check 24-pin cable voltages. All powered pins were within proper range.

 

After using screwdriver, paperclip, pocket knife, kitchen knife, spoon on 2-pins responsible for powering on motherboard I decided the problem was in motherboard. When I flipped I/0 switch on power supply the Aorus logo led turned on for 1 second only but CPU_FAN and SYS_FAN were not spinning. It was all quiet. No speaker in my system by the way but I doubt it would beep with motherboard not powering up.

 

I shipped my motherboard to PC repair shop since it's still under warranty and after testing it they called me and told it works. Receiving it back nothing changed on my side. I still couldn't power it on. Took PSU to 2 electronics repair shops where they used Chinese power supply voltage tester. They told me my PSU works. I wanted them to plug it into their computers but they told me they don't want to take the risk of damaging PCs of their clientele.

 

I took my motherboard, CPU, RAM and PSU to PC repair shop and paid money to check if my motherboard works using my components only. And what do you know? It worked right away and I couldn't believe my eyes. Technician said all works, there is nothing more to check.

 

I tried powering my motherboard using exact same components. It didn't work. Tried plugging off UPS from wall outlet to use battery's power and it didn't work. I took these components to my neighbor on 3rd floor in my apartment thinking electricity in my flat might be not "clean" but it didn't work again.

 

That's the anomaly my friends. Either evil spirit possessed my motherboard or PSU or they just hate me. Maybe I need to call techsorcist. I don't know what to think but I am not going to lose my sanity because of that.

The paperclip test is worthless to check a PSU...

 

Have you called Corsair....?

@Spotty I have described my issue above.

 

@Ankerson I am non-US... Do you think emailing Corsair will help? I asked about my problem on eSupport Gigabyte but they just tell me to take all of my system to check in PC repair shop, which is what I did but without chassis, HDD and SSD. They have no clue or play dumb.
