I recently got the MSI MPG A1000G PCIE5 1000W power supply and it unexpectedly died on me after just a couple of days. Since unplugging all the cables is a huge hassle, I'm considering just replacing it with the same model and keeping the existing connections. However, I'm wondering if this PSU is generally considered reliable or if my experience is indicative of a bigger issue with it. My setup includes an Intel i5-13600K and a brand new Zotac 5080, but while gaming, I experienced lag, and when I tried to reboot, the fans were spinning rapidly and there was a strange noise—like something was stuck in a fan. After opening it up and trying again, the loud fans persisted but the noise went away, only to have the system shut off by itself and not restart. I tried my old PSU, and it powered on without any problems. What do you all think I should do? Thanks!

MSI PSUs are generally reliable, so it sounds like you just got an unlucky defective unit. I’d recommend using that warranty if you still can.
Why not return this PSU and try a Corsair or another brand instead? Just keep in mind that Corsair sources units from various manufacturers, so make sure to pick a well-reviewed model!
Yeah, but Corsair doesn't manufacture them themselves. They may have some good models, but you can also end up with a bad one, so I’d rather be careful.
I've used a mix of MSI's MPG and MAG PSUs, and never had issues with them. If you do go for the same model, just swap it out and reuse the cables without hassle. But watch the new one closely after the switch to make sure it’s all good.
I've had good luck with MSI MAG 850W PSUs for friends and family builds, so hearing your story sounds like you might just have received a defective unit. It happens sometimes.
Is there a difference between MSI MAG and MSI MPG?
Regarding the warranty, MSI backs these PSUs for 10 years, which is a good sign! Your experience could just be a case of bad luck. However, the symptoms suggest there might have been an issue that triggered the PSU's overcurrent protection to shut it down. I’d avoid opening it, as capacitors can still hold dangerous power.
Is there a way to find out what might have shorted my PC if that was the issue?
For solid reliability, checking out Seasonic could be worth it. They tend to make their own units and have a good reputation!
