    Default Are we getting too paranoid over PSU's?

    Has anyone here ever had a PSU that died and took components with it? I used no name brand on my old computer for 8 years, it only went in silence without harming anything. I used some TOCHI brand PSU on my LG laptop that lasted 6 years, I replaced my old PC with another no name brand and it went another 2 years before I retired both the laptop and the computer.

    I've never heard anyone's PSU taking their components with it. I don't think these things are too complicated to make, or rather unsafe.

    I just realized I was getting bit too paranoid over PSU because of how much I spent on my new build. I am starting to think I am worrying for nothing, every single brand has bad reviews and lemons, and it doesn't matter all that much as long as you buy a brand name PSU since they all come with good amount of warranty. And if a PSU lasts a year under proper hard conditions (depending on advertised wattage) it can probably last several more years.

    Quite a few times.

    It's not always about the PSU failing so much as it can be other hardware failing and causing a power related problem. There have been plenty of reports across the web of shorts causing melted connectors and burnt PCBs because the short didn't cause SCP to trigger, and there was no OCP to stop the PSU from doing it's job.

    That, of course, is a larger issue.

    But I have seen PSUs burn up motherboards because the power was bad. Funnily enough, the majority of those boards were MSI. Wonder if they just had VRMs with little to no margin.

    That used to be a huge issue with MSI. I honestly would say that sold mostly junk before recent times even though they had some popular high end boards; almost everything outside of the top-end had awful VRMs. Especially back in the S775 days, tons of burnt up P35 / NF650i boards even when competing Gigabyte/Asus boards had no trouble.
