[SOLVED] What are the disadvantages of using a higher wattage PSU?

[barkersofgeraldine]

I purchased an 850W PSU

I didn't really count how much power/wattage my current build needs; but instead based my purchase on what I think will better accommodate future upgrades on the PC, i.e. a better GPU, like an RX 5500 XT

Anyway, what are the disadvantages (if any) of using a higher wattage PSU for a build that won't get close to using 700-850w???

No disadvantages since the system only draw what it needs.

Advantages.

• More headroom for an upgrade later
• PSU won't be running as hard as choosing a PSU closer to the system total draw.

Think we would like to know what you bought.

Also on lower use, like below 10% usage, you can get less efficiency, some psu's start to tick nowadays when that happens. Nothing to worry about, but some think it's annoying.

Don't really need 850watts for an upgrade to a 5500XT.

The only disadvantage is the initial cost, compared to buying what you actually needed. It will only draw power that the system needs, so no increased cost just because of its capacity. Since it will only be cruising it will probably last longer and maybe even be quieter. Over-provisioning, to some degree, has advantages.
