Whether you’re planning on building a new gaming PC and need to pick the right power supply for it, or you’re upgrading your GPU and you want to make sure it’ll actually work with your current PSU, this video is for you. Picking the right wattage is incredibly important, as you can easily run into overcurrent protections, or worse on cheaper power supplies, you can start to have degraded power which can damage literally every component in your system. So, why is it so hard to get the right wattage? Well, custom computers are complicated. Two systems can need completely different power supplies - one with an i9 and a 4090 would need a considerably higher wattage than an i5 and 4060. In recent years we’ve also discovered a new problem, which is that when a graphics card fully switches on to start rendering a game, it often draws an incredibly high amount of current - known as a current spike - which, if your power supply isn’t suitably oversized, can trip the overcurrent protections and just shut your system off in an instant.

    I have the PSU wattage stuff pretty much sorted now thanks. My brain starts to melt when I get a multi rail PSU and working out if I have enough power in each rail to fully cover an individual component like a GPU. Would be interesting to see you cover this aspect in another video in future.

    Sounds like a Mechanic my Father saw once. Wasn't sure if part A or part B was bad. Just keep driving until one breaks, then we'll know. It was very comforting as he was trying to make sure all was good before a trip across the country...

    You could always just undervolt hardware as well for lower power consumption with barely any effect to performance.

    it's not that true.. because your PC didn't draw out much power all the time, just get the same watt as the PSU or below just about 100w is good enough

    Oh no. I have Core i7 1700 cpu and I'm planning to pair it with a 3060 and my PSU is only 600w silver rated. Could I still live?

    You must also factor in the loss of power output over time over the years with the power supply. The 850watt out of a new power supply will eventually drop to 800 or even 750 watts or less over time. Also selecting a power supply that matches what you need is not the right way to go. Even factoring the over voltage spike you need to add a bit of overhead. You don't want to be pushing the power supply to its limits all the time that you're using the computer.

    would a 1000w gold PSU be too much for a 650w pc?
