Computer fails to power on, power supply appears normal.
Computer fails to power on, power supply appears normal.
In the last few months my setup with an old EVGA G2 550 PSU has been facing random reboots. After turning off the ECO mode, the issues seemed resolved. Now the machine won't power on at all—no response when the case power button is pressed. However, USB ports still supply power. I checked the PSU using a makeuseof article, and all measured pin voltages appear normal.
How are we determining those brief surges? There are aspects beyond what a standard Kill-A-Watt device can capture. You also need to stay above 400W since dropping below risks inaccurate readings, and a 200W power supply won’t be significantly cheaper.
Take it off and open the cover.
Remove dust and any unwanted particles.
Check visually and by touch to ensure every connector, card, RAM, jumper, and case part is completely and securely positioned.
Shine a strong light on the area to spot any signs of wear.
Well, it's showing all the usual signs a failing PSU would experience. EVGA produced some excellent PSUs back then. The G2 performed very well during its time. Plus, the ability of the PSU to fail mid-flight could destroy another piece of equipment. And considering its age, it seems to be struggling now.
Yes, you must use a real load tester and an oscilloscope to properly test a PSU.
Cool, cheers. I already have PURE POWER 11 (400W) in a ready-to-use basket. It could even drop to 300W, since I gave too much advice when setting up the box, which is why the 550W G2 was needed. I never thought anything under 200W would come out of the wall before. I need to make sure it's fair to replace it now. Will check back once it arrives.
Wait, list your specs so we can determine better. If this is a gaming rig of any description, then I wouldn't touch a 300w PSU with a bargepole. The motto, here being " Get higher wattage PSU to allow your current system to run well, and have enough headroom to move to a more higher powered system down the line.
The device functions mainly as a continuously operating Linux server, drawing 50-60 watts from the power supply. It's occasionally utilized for Windows gaming with a dual-boot configuration. The storage drives aren't connected at any time. Eventually, a dedicated gaming box will be assembled, allowing it to run purely as a server again. The GPU may still be employed for transcoding tasks like Emby or Plex every now and then.
