Too much Power bad?

[ojhiop21]

Hi,

I currently have a 500w PSU and my components are fine with that, however, I am wanting to slowly upgrade my PC and power supply is first on my list as it's already slightly faulty.

If I go from 500w to 750w is too much power bad for the components, or should it be fine?

Currently have amd 6600k
R7 260x

Thanks.

It will be fine, the PSU will only supply the power needed for the system.

It's not bad for the components but a 750watt power supply is way overkill for that system and won't run at peak efficiency with the load your system will put on it. I would look for a quality 550watt power supply or up to 650watts if you plan to add a more power hungry GPU in the future. Don't buy some generic junk psu off ebay or something.

A 500W PSU is enough for a pretty big rig. At least if it's a decent brand. You wouldn't have a problem running things like a typical GTX 1080 on it.
Bigger power supplies are mostly useful if you have more than one GPU, a huge case with a bazillion drives and other things.
That said, a power supply is usually the most efficient if it runs at around 50% load, so, it could help your utility bill. If it helps enough to recoup the higher price is different question.
I've got a 500W PSU in my case, and I have 3x SSD's, one mechanical HDD, a PCI sound card, a wifi adapter, a core i5 and an RX480 and all sorts of joysticks, gamepads and things connected to the USB ports. 500W is a lot of power.
