Need Recommendation, 700-800W modular Gold/Platinum

Need to replace the beating heart of my build, it's a good PSU but realised it's 12 years old now. (Enermax 550W Platinum). Had a look at the tier list but it was a bit confusing.

It's been fine with a 3900X and 5700XT but think i'm pushing it a bit in its twilight years, anyone have a good recommendation that isn't super premium? £100-150 would be okay.

I tend to stick to 200-250W for GPU and maybe 150W for CPU so it should mostly sit around 500W if i'm caning it; so 700-800W should put it squarely in the efficiency window.

Had a bad experience with Seasonic many years ago, but I think the blame would have been with Gigabyte actually. The Seasonic would not power up the board so I had to RMA it and OcUK tested it, said it was fine, RMAed it back to me and it still wouldn't power up the board so I had to RMA it again and swapped it for the Enermax which has been perfect.

I know Corsair can make good PSU but they have like 8 million different SKU so it's hard to pick a good one.

Reminded myself that the last PSU lasted 12 years so decided to pony up for a good one, ordered the Seasonic Prime PX-750 Platinum which should hopefully last me through a few builds and the efficiency should slightly offset the price over 5-10 years.

Thanks for the tips all, I got one of the higher end Seasonics as hopefully it's gonna stick with me for a decade or so and has a 12 year warranty, the Enermax is 12 years old (got it with my i7-920 way back when). The RMA process is usefull, but the retailer will deal with it for the first year and in my experience is that things either break very early or at the end of their working life. Seasonic seem to RMA to the Netherlands and will keep my Enermax as a back up.

Went a little over budget to get a Platinum because they are typically built a bit better and a few W/H over the lifetime of the unit will probably mitigate the extra cost. For power consumption, i'm definitately in the 400-450W peak if you absolutely cane it. During the recent heatwave I had to power down the computer entirely, and summer gaming is mostly revisting older titles that stress the GPU up to about 60W.
