Question Using my 13-year old PSU on a new build ?

[yos3mIte]

Greetings all. I'll be putting this together -

MBD: B650E, X670 or X670E (Looking to have PCIe 5.0 on a new mb for the future)
CPU: Ryzen 7600
GPU: 5700 XT
RAM: Corsair DDR5 16GB
HDD: Western Digital 250GB Blue (just bought new, I plan on adding/replacing with a new SSD at some point).

I will use the same case, keyboard, mouse, and a BenQ monitor from about 2016 that works well.

The question I have is, the PSU is an OCZ ZS 750W I bought new in 2011. Has worked great all this time, it has 6 + 2 cables which I've read works fine in 8-pin sockets). I know its an older PSU but the wattage should be more than enough and it has worked flawlessly since buying it. I plan on getting a new PSU for this in the next 6 months. I'm sure comments will be to not use a PSU this old but are there any real dangers? Will this PSU be workable for a few months at least? I'm trying hard to keep this build near $600 currently.

Thanks for any insights.

For your new build work in a new power supply.

If you were asking can my old power supply get me by with a less demanding GPU like a GTX 960 and 4th gen Intel CPU i7 in that grey area more likely.

New parts, 13 years age on power supply. Don't skimp on feeding new parts with proper healthy power supply.

It's time to upgrade the PSU.

Thanks for the replies.

I plan on getting a new PSU sooner than later and thanks for the link I've been looking at an 850W modular PSU when I do buy one.

The older one is 750W as noted so plenty of power and electricity is electricity, if the cables on the older one will plug in and work with the new parts I listed it should work fine 'I would guess'. I've been going between spending $400 and building a DDR4/ PCIe 4/ AMD 5600 but for a couple hundred dollars more I can get to DDR5 and PCIe 5 and can swap out the CPU for something better later and the MB will be better suited to future proof this build for as long as possible. I'm using my old ATX case and peripherals as I noted.

In all the reading I've done which is considerable the 6 + 2 cables on the older PSU should work fine in the 8 pin power ports for the newer parts and it generally looks like the cabling on the old PSU will fit most everything today as well. I'll look for a PSU on sale the next few weeks I guess.

Modular cables are not universal. Re-using modular cables without knowing for a *fact* that the exact pinout on the PSU side is identical, is a great way to no longer have a new part (and this wouldn't be a warranty issue either).

We have dozens, probably hundreds of threads in here where someone used old cables with a new PSU.
Resulting in the release of the Magic Smoke.

Don't do this.

Use only the cables that come with the new PSU.

The only issue I'm asking about is using the OCZ ZS 750W with the newer MB, CPU, GPU, and ram I listed.

Modular cables are not universal. Re-using modular cables without knowing for a *fact* that the exact pinout on the PSU side is identical, is a great way to no longer have a new part (and this wouldn't be a warranty issue either).

Thanks for the warning, I have come across this in my reading the last few weeks. Whenever I build a new pc I follow very slowly and precisely how the various manuals for components say to put things together. The older PSU is not modular and I know CPU power connectors and GPU power connectors can't interchange. With all the keying with connectors now its hard to imagine someone forcing something into the wrong connection but we know that certainly happens. Again thank you for the warning, I continue to get up to speed on the current hardware for a build and every bit of info is meaningful.

The more reading I do the more I'm confused on why manufacturers do this, why wouldn't they just make it all standard like ATX or PCIe. Thanks for they heads up though I log all the tips I get.

Thanks again.

Thanks again.

At the component end, they are all standard.
At the PSU end, not.
