PSU died in 24 hours

Hello
I've had a pc for about 3 years and the psu died. I thought I'd take this opportunity to upgrade it while changing the PSU.

Thought all was well and left computer on over night to download some games. Then started playing Forza and 10 minutes in the whole thing died again.

Is there anything that would cause a PSU to die in 24 hours? I'm paranoid something is wrong with my machine as it's now gone though 2 the latest being a 750w one

The specs are below and thank you for any help

AMD FX 8320 3.8GHz 8 Core CPU
Gigabyte LMT-USB3 AM3 Motherboard
16GB DDR3 Memory (2x8GB) 1600MHz
Radeon RX 589 8GB Graphics Card
1TB SATA III 3.5" Hard Drive
1TB SSD
Cooler Master Hyper 212 EVO CPU Cooling
5 arctic f20 cooling fans

While you said 750W you didn't actually mention exactly what PSU it is. It's very unusual for a good quality PSU to die especially while delivering well under its specified wattage, so the one you bought might be important.

I don't know anything about pc hardware brands or how to tell if one is good quality or not. I just went for one with a high watt which I could get during lockdown. It is an I-CHOOSE LIMITED LMS Data X700 700W ATX PSU

Would you mind perhaps pointing me in the direction of some quality PSU manufacturers and letting me know the minimum watt PSU which would suit my pc?

Many thanks

Michael

The wattage is irrelevant, especially if the manufacturer lies about it. That's a poor quality PSU with only 456w available for the graphics card.

You want something like this:

You should feel lucky if only thing that happened was PC shutting down.
That's definitely this level scam garbage and you should have bought good fire extinguisher with it.

Not sure what agency in UK does safety requirement testing, but would definitely hint them about such junk, whose only testing was no doubt that it didn't burn factory down.

This would be about light year better.

S12III is outsourced cheapo too pricy for lacknig quality, very outdated design and mediocre everything.

Yeh, avoid the S12III. It's one of Seasonic's turds, although there aren't many of those.

Thank you for the advice guys. Went for a better quality PSU even though only 600W and its working perfectly. Much appreciated
