New PC, old PSU. Is it a good idea?

[rtsiqueira]

I'm building a new PC and using my old PSU.

Zalman ZM600-GLX, it is 5 yeras old.

Is it a good idea to keep it for this building or should I buy a new one?

Ryzen 5 3600
ASRock B450-M Steel Legends
Corsair Vengeance RGB PRO 16GB (2x8) DDR4 3000MHz
GTX 1070 Strix OC
1 SSD Kingston
2 HDs Seagate Barracuda
2 Fans 140mm Corsair ML140 Pro RGB
Watercooler Corsair H100i Platinum RGB

If you value your hardware, I wouldn't. I'd spring for a new PSU

PSU lose their ability to provide stable power, slowly, over the years. They can also spike, and push that power to the new hardware, frying it.

Which is why I say, if you value your new hardware, I'd pair it with a new PSU

It wasn't a good PSU 5 years ago.  It's definitely not a good PSU now.  You're lucky it's lasted this long.  Replace it.

A psu that's worked fine for 5 years is not good. OK.

 

You can say if it worked for 5 years it'll continue working for another 5. I also don't believe that "it destroys your components" etc. Have any of your components died in 5 years due some unknown problem? Seems not. As long as wattage is enough, I'd go with it. 

 

Few reasons to buy a new one would be; It started to make high pitched noise, or new build requires more than 90% of the max output of current PSU, or that it is very inefficient and that you want to buy 80 plus gold.

Give me your best shot.

 

I like Corsair, EVGA and Cooler Masters.

According to https://outervision.com/power-supply-calculator I would need 476W

Your current PSU is 600 so yeah, its more than enough. In reality it will not even pull more than 450w. I would have more trust in a PSU that has worked flawlessly for 5 years than a new, untested one.

While it's true that you shouldn't buy untested PSU (as in with professional reviews, not your personal experience, it means nothing) if you have better options. This particular Zalman PSU is group regulated, it would've been okay with OP's previous PC if it were smth low-powered and old, it's definitely not for this new rig as it's quite old group regulated platform.

I trusted my old power supplies twice, both times my motherboard got fried when I upgraded some parts.

 

Now I'm a bit more careful about using the old PSU.

You need a new PSU , the quality of your current one is lacking by today's build standards.

[rtsiqueira]

Corsair CX650 80 Plus Bronze would be a good fit?

Speaking about future upgrades: I may change the GPU for a RTX 2070 or better.

Entirely up to you but the reccomendation is usually when the psu is out of warrently its a good time to replace it. My ax850 was 8 years old until the caps blew on it
