Was doing some web browsing on the PC when it shut down unexpectedly. Couldn't power it back on. The RAM LEDs remained lit, but nothing else.

I disconnected the PSU, let it rest for a few minutes, reconnected, hit power button... nothing. RAM LEDs lit up, again, but began blinking randomly. I tapped the PSU's reset button and BANG!!!!!!!!!!!!! No smoke but a scary looking spark flared up inside the PSU. Never saw anything like it in 15 years of building PCs.

I'll contact Seasonic for warranty service. PSU is only about 18 months old.

Any concern that the explosion damaged other components? I ordered a new PSU -- Super Flower Leadex VIII 1200W. Don't want to wait for days/weeks on Seasonic.

I hope your RAM is ok.
 
Most of the time it doesn't damage the other components, but you never know. The Super Flower Leadex VII and VIII are great PSU's, they're what I mostly use.
 
No smoke means it's unlikely to be a capacitor. A resistor or mosfet blew up?

You would only get damage if something short circuited and sent voltage where it wasn't supposed to go. Generally unlikely with most well built PSUs.

Hi Mad Maxx,

Seasonic Support Team here. Sorry about the failure; that's not the experience we want anyone to have.
If not yet done, please open an RMA through our support portal and mention this thread: https://seasonic.com/consumer-product-support-or-sales/. Your unit is well within warranty, and advance replacement is available if you are in the US or Canada, so you won't need to wait for the return before a replacement ships. Please don't open the unit, since we'd like to analyze it.

Thank you and once again, we are sorry for the inconvenience.

I might have to buy me a couple of Seasonic PSU's again just for the awesome customer support.

That’s all I’ve run for years now, at least 15. Their customer support (not just here) has always been top notch imo. Not to mention the higher end units are virtually bullet proof in all the builds I’ve had over the years.

I was going to say 15's a lot of PSU's, but I think I might actually have 20+...
 
there is a reason they are at the top of recommended lists. having a rep here is a bonus though.

You almost never need it, particularly if you get their high end Prime units. They make really, REALLY good PSUs. They are my go-to and have been for a long time. The only reason I got the MSI in my other post is that Seasonic has been quite a bit delayed on their Optiguard PSUs that will have the same thing. If they had them out, I 100% would have gone Seasonic and it is possible I will get one when it comes out, even though there's literally nothing wrong with the MSI unit and it is very solid.

I also like getting from companies where they are both the ODM and the company that makes the final product. While there's nothing wrong with getting a PSU from a company that didn't make it, I just prefer it all be one vendor, keeps things cleaner.

Yeah. I've only had 4 Seasonic PSU's, but I'm still using the Platinum's from over a decade.
Seasonic 1000W Platinum
Seasonic Platinum SS-660XP Active PFC F3
Seasonic X-850
Seasonic X-650

What's the latest and greatest Seasonic PSU's these days?

The Prime TX ATX 3.1. Titanium units, with native 12v-2x6.

They have new units on the horizon, an enterprise unit that reaches 80 Plus Ruby, and their Optiguard stuff which is per-pin current monitoring for 12v-2x6 but no word on when those will be out so at the moment the Prime TX.

Sorry I meant 15+ years. I probably have… 7-10 units still in use, some easily 10 years old. They just haven’t showed any signs of dying and they are on old systems.
