Phew, so NVIDIA launched the new RTX 50 series of graphics cards at CES 2050 - including the RTX 5090, RTX 5080, RTX 5070 Ti and the RTX 5070. The other GPUs in the series (like the RTX 5060 and maybe RTX 5060 Ti) will come later on in the year.
However these cards have a higher power requirements - with the RTX 5090 having a TDP of 575w, much higher than the 450w of the RTX 4090.
So can you PSU cope with this? Do you need to run out and buy a new PSU? I answer these questions and more, and I also talk in detail about the 'melting' 12vhpwr connector, ATX 2.0 vs 3.0 vs 3.1, and whether you need to change your 12vhpwr cable to a 12vh-2x6 'cable' (spoiler alert: you don't... but you might need a new PSU!).
