New PSU: Loud Pop, Sparked, and Dead, what happened?

[MiNuN]

Hi there!

My current 1200W PSU is dying and I need a new PSU

My computer is old so I did not want to spend too much and ordered this 1000W PSU
https://www.amazon.ca/gp/product/B09BYT4P91/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

I received it today and swapped it out with my current PSU, less than a minute after logging into Windows, there was a loud pop and sparks coming from the PSU housing compartment, my computer shut off immediately and I unplugged everything, it fried my surge protector (Thank god for it, I never thought I would see the day)

Good news is that I put my current PSU back in and it is working, nothing dead (except my surge protector /sadface)

I would like to treat this as a life lesson, what could of caused it? A few things I could think of but quite not understand

    Was it because I bought a no-name brand PSU? There is not a lot of information about their brand but enough to gamble that it would work

    Was it because I bought 1000W instead of 1200W?

    My GPU used 2 8-pins PCI-E cables with my current PSU, with the new PSU I noticed there was 2 8-pins on 1 cable and opted for that instead of two separate cables, did that cause it?

    There was not enough Molex cables for my sound card, Asus Xonar Essence STX, so I decided not to use my single Molex cable for it but left it attached to my MoBo

    I did not change the pin connector for the fan connected to CPU FAN on my MoBo

Any recommendations for a 1200W PSU that won't explode?

Yes. I've never heard of "ARESGAME" myself.

I think it is unlikely your system actually needs 1200 Watts, even with a 30-series RTX card. If it's truly necessary, A reliable 1200 Watt supply will set you back 300-400 dollars. It's uncommon for a system to require more than 850 Watts, though. I'm using a Corsair RM650 650-Watt supply with an overclocked 4770K a 1070, and a USB3 and Sound card that both take a power input and it's been running fine since 2013/2014 when I built it (originally with a GTX 770).

Sure sounds like you experienced a dead short somewhere.  I would carefully inspect the power cord which came with your new power supply for any signs of arching or a burnt smell, and or also carefully inspect all of the power connections inside your PC's case for signs of arching, melting, or bunt smell.

Also, are you fairly certain that you didn't accidentally plug one of the connectors onto the motherboard upside down.  I can be done if you put enough force onto it.  Maybe your new power supply just blew a fuse, and perhaps it can still be salvaged.
