Computer turns off automatically, faulty PSU?

Hi everybody!

I have a computer with an AMD FX-8150, 32 GB of ram, SSD and harddisk and a decent GeForce graphics card.

My computer automatically powers down, sometimes after a minute, sometimes just when I open a tab in Firefox. Most of the time it will keep on running when I play Skyrim (at high settings) or Minecraft.

I tried turning down a couple of cores. Right now it's running stable with 2 cores active. If I activate more cores it will power down.

I ran temperature monitoring software to see if it's a heat problem. The processor temperature stays between 40 and 60 degrees Celcius so I think that rules out overheating.

Could it be that the PSU if failing? Because after the computer turns off, I have to disconnect the power before I can turn it on again.

Right now I have a 600 watt PSU, maybe I need 800 watt?

Thanks for your help!

when the computer shuts down did you check immediately the temperature in BIOS? if not then go check it out to see if it's hotter then it should be. a failing PSU can cause intermittent power failures but also a hot CPU.

Hey, not if our issues are exactly similar, however one of my pc's has this random issue of shutting off as well, however it seems to be with my motherboard and the onboard audio, USB plugin slots, if i use the usb ports or plug in the earphones to the back panel of the computer, i can hear some electrical static sounds. But once i start playing a video the PC will shutdown and i have to disconnect the power before i can turn it back on as well. Have you tried to check if all your fans are working properly? Also try removing all your usb connected devices to try and trouble shoot, perhaps the board could be faulty?

I tried turning on the PC as soon as possible after the computer turns down. The bios always gives me a stable 40 degrees celcius. Seems normal to me?

Also, I opened the PC, all fans keep spinning...

hum...

and this computer shuts down in a random fashion or only when performing a certain task (gaming, video playing)? you can start to remove all non essentials devices from the computer (extra disk, geforce gfx card if the mainboard has a dedicated gfx, only leave the minimum ram as possible) and try to simulate the event that causes the shutdown; start adding more devices until you find a device that when connected will cause a shutdown; also activating more cores will cause the computer to consume more power and in the event of a faulty PSU that can cause a shutdown.

remember this can be somewhat time consuming troubleshooting.

So, test results... the computer still crashes if I only use 1 8GB RAM module. I tried exchanging the RAM module for another one. Same result.

The temperature of the CPU is around 20 degrees Celcius when idle and it never passes 60 degrees Celsius when I use my computer.

I did a full memory check, no errors found. All 32 GB are alright.

No memory and no temperature problems. Right now I am able to use my computer with only 2 cores active... it never powers down. Anyone got an idea what I could try before going out to buy a new PSU?

Thanks!

Alright! I got a new PSU (XFX Pro 750W) and my computer is up and running. It's running full force with all 8 cores enabled. CPU temperature is 15 degrees C at idle and never exceeds 40 degrees C. Also, my computer is now super quiet... Turns out the noisy part of the computer was the PSU. I'm so happy now. :D

Which PSU did you have? I am having the same issues with the Corsair TX750 model, have to exchange it for a CX or something else. The fan on it is just broken and loud :(

that sounds like a poor earth bond in the chassis mate.

 

Check that every possible screw hole is attached to a proper mount to earth the board.

 

Most boards have at least 6 IFAIK easy to spot they have solder around the hole, its this plus the screw in the metal mount that earths the mobo/components to the metal case, which is in turn has a true earth via PSU to your house wiring/outside world earth point.

 

Im not trying to be sarcastic on the last line :)

    • IBM reveals sub-1nm chip technology, production expected in another 5 years

    • This Chinese company is reportedly developing a feature Apple and Samsung can only dream of

      This Chinese company is reportedly developing a feature Apple and Samsung can only dream of by Hamid Ganji While companies like Apple and Samsung have been relatively conservative with their devices’ battery capacities in recent years, Chinese manufacturers have taken the competition to the next level by introducing significantly larger batteries. However, the latest report from China suggests that a local company may already be developing a smartphone with a whopping 14,000mAh battery. Chinese leaker Digital Chat Station claimed on Weibo that a smartphone maker is developing a device with a 14,000mAh battery. If true, it would be the largest battery ever used in a smartphone and could, in theory, provide up to a week of battery life on a single charge. The leaker did not reveal the name of the company behind the device, but there are some clues. This week, HONOR unveiled the X80 Pro Max in China with an 11,000mAh battery and 90W wired charging support. The company also launched the Honor Win in January, which packs a 10,000mAh battery. HONOR, a former subsidiary of Huawei, has a proven track record of developing smartphones with unusually large batteries. However, other Chinese brands, including Xiaomi, have also launched devices such as the Xiaomi 17 Pro Max with 7,500mAh batteries. Though Chinese users on Weibo also believe the company behind the new battery is HONOR. Interestingly, Digital Chat Station said the device with the 14,000mAh battery weighs around 220 grams, making it lighter than the Apple iPhone 17 Pro Max (233 grams) and slightly heavier than the Samsung Galaxy S26 Ultra (214 grams). The iPhone 17 Pro Max currently packs a 5,088mAh battery in eSIM-only versions, while the Galaxy S26 Ultra features a 5,000mAh battery. Neither device is expected to see a dramatic increase in battery capacity in its next-generation successor. So when it comes to battery comparison, Chinese brands are unbeaten. HONOR smartphones are currently available in the EU, but the Chinese brand has no official presence in the United States due to restrictions imposed by the U.S. government.

    • Qualcomm takes on NVIDIA with new Dragonfly CPU and AI chips

      By pradeepviswav · Posted

      Qualcomm takes on NVIDIA with new Dragonfly CPU and AI chips by Pradeep Viswanathan Microsoft, Google, Amazon, AMD, Meta, Apple, OpenAI, and several others have been developing their own chips for AI infrastructure. However, NVIDIA still remains the dominant player in the market. Today, Qualcomm announced a major expansion of its data center infrastructure portfolio to better compete with NVIDIA. The new lineup includes the Qualcomm Dragonfly C1000 CPU, Qualcomm High Bandwidth Compute technology, the Dragonfly AI300 inference accelerator, new connectivity products, and custom silicon solutions. Qualcomm claims that this new lineup improves performance per watt, token throughput, and total cost of ownership for AI data centers. The Dragonfly C1000 is a new data center CPU built with Qualcomm’s custom Oryon cores. This chip will feature more than 250 cores, frequencies above 5GHz, and a chiplet-based design. Qualcomm claims that this new C1000 can deliver more than 2x better performance per watt compared to existing server CPU offerings based on specifications. The Dragonfly C1000 will support PCIe Gen 7 with more than 2TB/s of connectivity, along with CXL, advanced RAS features, and both air and liquid cooling. Qualcomm expects the Dragonfly C1000 to be commercially available in 2028. Additionally, Qualcomm and Meta announced a multi-year, multi-generation agreement under which Qualcomm will supply Dragonfly C1000 data center CPUs for Meta’s next-generation server fleet. Qualcomm also announced High Bandwidth Compute, a new near-memory computing architecture designed to address AI’s memory bandwidth bottleneck. HBC Gen 1 will debut with the Dragonfly AI250, which is expected to sample in mid-2027. The AI250 will deliver 133TB/s per card, an 18x increase in effective memory bandwidth compared to the AI200 with LPDDR5X. The new Dragonfly AI300 with HBC Gen 2 is a rack-level AI inference platform from Qualcomm. Qualcomm claims that the AI300 can deliver 4x to 8x better performance per watt compared to existing GPU-based architectures based on memory bandwidth per watt per card. The Dragonfly AI300 is expected to be available in 2028.
