Hello!

I have a Cooler Master G750M PSU which turns 11 years old this year, and which gave no problems whatsoever. But in a couple of months, i want to replace my old RTX 2070 with a 4070 TI Super.
So, since i heard that PSU's usually last only for 10 years, i was wondering if i should upgrade this one as well?
Or should it still be sufficient for a couple of years more?

So, does anyone have any idea, or is there someone that have experience with old psu's?

Thanks in advance.

Greetings from Martijn
 
This was a solid PSU for a Cooler Master of this era, but any 11-year-old PSU should be replaced with a major upgrade like this. Generally speaking, it's best practice, on significant upgrades, to replace any PSUs that are old enough to have passed their warranty.
 
I found out that the cooler Master MWE GOLD 750 V2 isnt that expensive to buy.
Is that still a trustworthy psu to buy for the money, and maybe as solid as my current psu was?

Or should i avoid it for some reason?
Thanks in advance!
 
It's a decent one, though you can usually do better for similar or slightly more money.

PSU Tier List will help you to choose the best PSU out of hundreds of models on the market. From budget to the highest end Power Supplies.

Generally speaking, with a 70-tier card, I don't recommend (nor would I personally) going below Tier A on the link.

Can you elaborate why you wouldnt go below an A tier?

Quick edit:

I also found out of this one: https://www.thermaltake.com/toughpower-gf3-750w-gold-tt-premium-edition.html

But i didnt found out if this one is an A tier psu.
If i read the spreadsheet it could be either an a tier or a b tier..

So can anyone say for sure what it is?

In the case of the PSU from up above, the MWE Gold is costed down with some relatively cheap capacitors and MOSFETs. Also, a five-year warranty is quite anemic by modern standards, where most high quality PSUs are eight, 10, or 12 years.

A-tier PSUs are generally ones without a major flaw. And for a high-end GPU, I want it to be able to handle transient loads, have capacitors that have a long life, and be among the top PSUs in ripple mitigation and voltage regulation. High-end GPUs just aren't the place to cut costs, especially when we're talking an additional $10-$20 to go to a Tier A PSU in many cases.
 
found another one, which people also seem to be a very good psu:

But that one i couldnt find on the sheet at all, but some guys at tweakers say its a very good one, and only lacking behind the SF Leadex VII XG.
And also, that 850 gold is exactly in my budget.

So, do you agree with them on tweakers, or not since its not on the spreadsheet at all..

Thanks again
 
Usually, whether working or not, 10-year-old (or older) components are technologically obsolete, and not recommended for use with newer components that heavily rely on the PSU.

From this standpoint alone I would replace it with a new, compatible, PSU; money well spent!
