Question PSU upgrade help!

[dataheadj]

Hello I recently bought some new parts and contrary to what reddit testimonials said, my old 500W power supply is not enough to handle the rig. I have spent 4 days working through issues installing windows etc. and am desperately trying to complete the upgrade so I can get back to the usual. Here are my specs
CPU - Intel Core i7-8700 @ 3.2GHz
Motherboard - Z370 AORUS ULTRA GAMING WIFI-CF
GPU - Nvidia GeForce GTX 4070
Ram - 64GB DDR4
2TB M.2 SSD (w/ os)
(256GB SSD
2TB HDD hard drive)
I dont even have the other 2 drives in right now due to psu 🙁
Power Supply - EVGA 500W 80+
Case - CH560 Digital (only mention because of dimensions)

PSU was bought about 7 years ago

I found a used Corsair CX750M 80+ Bronze for $45. This would be faster than ordering from amazon, but I do not know too much about power supplies and do not know if this is a good price / good PSU.

Any advice or other recommendations are welcome

Unfortunately, you have a real mess on your hands. The only 80 Standard EVGA PSU at 500W is the EVGA W1, a very outdated, cheaply made PSU that ought to only be used, at most, with office PCs or grandma's solitaire PC. Anything you've been using with that has a long-term risk of failure associated with it now because of the dirty power and poor voltage regulation those parts have been exposed to.

The CX PSUs these days are good budget PSUs, but with a recent 70-series Nvidia card, you're not even in the same galaxy as using a good budget PSU. And even then, if you were, you certainly never buy a *used* PSU.

This is as cheap as you can really justify with a GPU like this.

It seems like you've been long treating your PSU as a complete afterthought, unfortunately. A proper, quality PSU is *the* most important part of a build with a discrete GPU that requires supplementary power, not the cheap thing you try to fit it after buying all the fun things.

Thanks for the response, I built my pc with the original PSU in 2015 i believe and this is my first upgrade since. I definitely want to make my build last for as long as I can and do not want to cheap out, so with that being said are there parts that potentially could damage or break such as the MoBo?

Also im not tied to corsair, i just saw the posting for the used one online. Is there another psu that would be better around the same ish price range?

The one I posted is about as cheap as you can get for a good quality 750W that can safely run a 4070. It just happened to be Corsair because they sell a lot of good PSUs at reasonable prices.

At $49.99, there's nothing that, in the context of using a 4070, that's as valuable as the cardboard box it's shipped in.

You don't want to power a 4070 with an outdated 50 bucks PSU.
