old seasonic m12 600w psu and rtx2060 super question

[aygung]

hello everybody,

i have this old seasonic m12 600w psu sitting around. it's 13 years old and I used it for a nice 6 years without any problems (even when I was into computers and did overclocking with a Q9550. it's all in the past now.) and then this pc got retired. money is a very big issue so I will definitely want to go with this psu instead of buying a new one if I can...

 

I am planning to build a new budget pc for 3d design and cpu/gpu rendering.

ryzen 9 3900x and a rtx 2060 super. (msi rtx 2060 super VENTUS GP)

all the psu calculators show smth around 450-500w for this rig.

 

I can not find an answer to this question on the internet:

because this psu is very old, would it be compatible with a rtx 2060 super? 

and since I will do no overclocking I am guessing 600w would be more than enough.

 

*(back in the day I was using geforce gtx460 and an overclocked intel q9550 with this psu without problems.)

*(i live in Turkey, so even if you may have some nice alternatives to this psu with low prices, it most probably is not available here but please advice if you have a recommendation. I will look into it.)

 

thanks in advance for good advices.  please do not bother coming to say only yes or no if you don't have a point.

Don't get me wrong, but if you can afford a 3900X and a 2060 Super, then you should be able to afford saving a little more and buying a new PSU. You don't even need anything super expensive, a TX550M from Corsair or even a CX will do, but you never want to cheap out on the PSU, especially on a high-end system. The M12 PSUs weren't good even when they launched, so it being that old can only make matters worse. At least that's my take on it.

I wouldn't trust such an old psu with such a new and expensive system

You're spending a good amount of money on your rig, I would buy a new 600W PSU (at least bronze rated).

Callin ryzen 9 3900x and rtx 2060 super budget. Man plz you are spendin atleast 1500 dollars to that pc. Save some more on psu. You could cheap out whit buying cheaper rtx 2060 model

that's because the design that this PSU uses was much more relevant back then. aside from the modern things like sleep states and protections and whatever, this PSU is not independently regulated, which means its voltage delivery is much more suitable for old components instead of new components.

 

Under NO circumstances would I pair a 13 year old USED PSU with a $500 CPU. Just buy a 1660 super instead and used the saved cash for a new PSU that's actually good.

That PSU was built in 2007.

 

If you can't be bothered to buy a new PSU, you shouldn't be buying an RTX2060.

What does that even mean?

 

Like gimme a circuit design on both ends and explain why this even matters.

It doesn't need a circuit design. I'm not the one to explicitly break down why group regulated power supplies can go out of spec, but if you disagree then hopefully you'd have your own explanation as to why. 

 

I don't mean that the PSU is non functional, but it's well understood that group reg was designed for components that did not use the 12v rail nearly as much, especially compared to 5v, which was a long time ago.

I'm not disagreeing with what you're saying. I'm asking you to explain

If a circuit design comparison isn't needed, that's fine, but saying "it's well understood..." doesn't explain the above.

Usually I link to the piece that @LukeSavenije wrote about "why not to buy a group regulated PSU in 2019 and on" since it's not really easy to abridge and it's an easy read.

 

But of course not really everyone wants to read a wall of text, they're often cool with "it's too old"

The 10 link limit is just such a shame

thank you everyone for the comments. as i see i should get a new psu. thanks for the explanations. it helped.

It is independently regulated.

So many posts in this thread wasted on debating a false assumption...

I think they're confusing lack of DC to DC for the +3.3V and +5V as group regulation.

that's... a weird config they did there, but it looks kinda like it?

 

i didn't check beforehand, but the conclusion ends up being the same

 

it's a psu from 2007, it's 2020, time to replace that thing
