March 15, 2023How do I check my power supply wattage on Windows 11?
Windows 11 has no native PSU wattage display. Start with msinfo32, press Win + R, type msinfo32, go to Components, then Power. On OEM systems, this sometimes shows PSU data. On custom builds, it's almost always blank. HWiNFO64 is the best software option for monitoring live power draw across your components. The definitive answer still comes from physically reading the PSU label, or checking your purchase documentation if you built the machine yourself.

For the external AC adapter (the brick), look at the label on the adapter itself, it lists input voltage, output voltage, amperage, and total wattage. For the internal power circuit of a laptop, the manufacturer's support page using your laptop's model number is the reliable source. Search your model number + "specifications" on the manufacturer's site for full power details.

Can I check my PSU specs through Task Manager?
No. Task Manager shows CPU, GPU, RAM, disk, and network utilization, nothing PSU-related. There's no firmware or driver interface between the PSU and Windows that Task Manager (or any OS tool) can query. This is a common misconception circulating in older forum threads. The PSU is passive hardware from Windows' perspective.

how do i know what power supply i have in my pc | Tom's Hardware Forum
February 5, 2016 - Hi, what is the model of your power supply? Many 300W power supplies blow after drawing 200W. What is the exact model without me downloading some fishy file form a site I'm unfamiliar with?
Top answer 1 of 15

If putting a ram stick in the 4th slot crashes your machine, then something is clearly not healthy.
It would help to know what you are using for components. What motherboard, video card and power supply are you currently using? What type and speed of ram? Are all 4 modules the same?
I have had power supplies that start to fail by not providing enough current on certain rails. Symptoms were things like USB ports randomly dropping, usually during video intensive thing. The increased draw from the video card pulled more than the power supply could handle.
If you have tried more than 1 ram chip in slot 4 of the motherboard and they do not work, I would suspect you have a board problem, but it could also be mismatched ram.

Hi guys,
Is there any software or method to identify the power shortage on desktop PC components? My PC experiences the following issues:
- Randomly shuts down.
- High speed fan noise on first 5 seconds of powering it on
- Awaking PC from sleep sometimes cause auto PC restart, sometimes NOT (Random)?
- Status of HDD with CrystalDiskInfo software shows Good, 30 'C
- Updated Win 11 OS, Drivers
- Some errors in Event viewer related to Virtual box: updated and should be fixed now.
I know the motherboards has four RAM slots but only 3 of them are working. Putting another RAM in the fourth slots cause PC crash and restart.
How to ensure the motherboard and other components are in good health in this PC?!
Thanks.
