According to publishing sources speaking to VGC, launch sales for Sony's console far exceeded the UK's previous record holder, 2013's PlayStation 4, which sold some 250,000 units in its first 48 hours.
It means PS5 significantly outsold the launch of Xbox Series X and S in the region, which VGC previously reported had sold around 155,000 units on its first day
The most popular PS5 model at launch was the more expensive disc drive edition, VGC understands, which like Series X accounted for around two-thirds of UK launch sales.
However, the sales figures come with some caveats: due to significant supply constraints for both Xbox Series X/S and PS5, the consoles would likely have sold even better if more stock was available.
Similarly, any additional stock during the launch window for either Xbox Series X/S or PS5 will almost certainly sell out, especially considering that pre-orders made up the vast majority of current hardware sales, limiting the number of units available to day one buyers.
The platform holder which sells the most consoles in the coming months will almost certainly be the one which can get the most stock into market.
