I remember that when the 250W PSU that came bundled with my Enlight EN7237 case blew (almost 20 years ago), it tripped the breaker, but nothing died in the PC .

Yeah they do have short circuit, over volt, over current and fan control. Some say they have Power Factor control (PFC) but doubt it at this early age of PSU. Good to hear you did not loose any parts !

It did it's job and took one for the team.

Corsair RM750I and up (850, 1000) have 25A on the 5V rail and 150W on the 3.3+5V rails combined. I never encountered any problem in any of my systems not even with Athlon XP 3200. They are built like a tank and never had any issues with them. That being said they are not cheap.

The TX or TX-M series 650W gets you 30A on 5V, also with combined 150W on 5V + 3.3V, for a fair bit cheaper than the RM series. Still not exactly cheap though. And actually finding one to buy is another matter.

Decided to safeguard my retro rig. Ordered a Corsair RM850x . 212$ CAN is not cheap (had a 100$ gift card to offset it, though), but seeing that the next ATX spec is likely to be 12v only, I guess it is better to get one now . At 25A each on 3.3 and 5v rails and 150W total for them, it should suffice for my P3 1400 .

+1 for the Corsair RMx - I have been running the 550W models (which also spec at 25A on the 5V and 3.3V rails; 130W combined 5V+3.3V) for some time now. They even used to come with a 20+4 pin ATX connector, however the last one I purchased did not. Corsair was nice enough to send me a cable after some discussion with their tech support.

Imho 130-150 watt of combined power are not enough for a beefy socket a system, back in time the atx v1.2-1.3 best psu had 180-200 watt of combined power.

The TX650M has 25A each on 3.3V and 5V and 130W total, according to the manual .
I could not find the specs for the TX650 on Corsair's site .

My TX650 has 30A on the 5v.

There seem to be multiple versions of the TX650 and TX650M . One has 170W combined 3.3v and 5v, one has 150W and one has 130W (and correspondingly different maxes per rail).

Good job, Corsair !

That is not uncommon, as the years go by a newer of same version will have different specs. My older Antec True Power has diff specs than the newer versions. As specs and requirements changed over the years (or decades) some still use same model numbers but the spec's change as does the requirements of the time. In Corsair case they marketed parts, not made them, has been known for years they contracted the best they could under circumstances and most of their stuff is fairly decent or of very good quality. Just depended on who the contract was at the time....

I know that this happens, I just find it disingenious that manufacturers mostly don't bother adding version numbers when changes happen . I was expecting Corsair to be better in that regard .

Yes ! They could add a Version or Revision # or something to signify a change. There are a few PSU manufactures that do change the model number suffix when there is change but that is not too common.

Those might be out of date specs. This list of presumably latest models (ATX12V version 2.4) says 30A for 5V and 150W combined 5V + 3.3V across the 650-850W TX and TX-M range: https://www.corsair.com/corsairmedia/sys_mast … -spec-table.pdf

Even the latest CX-M line gets you 25A and 130W combined 5V + 3.3V at 650W, easily enough for almost any socket A build. And that one can be found for ~80€.

Or maybe that table is out of date ? I am not crazy about guessing games .

That said, I have been doing some research and 130 to 180 watts combined on 3.3v and 5v seems to be what older 250W to 350W PSUs used to advertise, and we know how optimistic those ratings were .

I remember running thunderbird 1400 on an Antec pp303x with no issue (until the caps in my MSI MS6330 gave out and started leaking; took about 2-3 years EDIT: probably less than that). That PSU was 160w on 3.3v (14A) plus 5v (30A) .

If you keep an eye out you may be able to find new old stock PP&C turbo cool power supplys on eBay every now and then.
Such as this one.
https://www.ebay.com/itm/Turbo-Cool-510-atx-p … 353.m1438.l2649

Unlike most other PSU's from back in the day like antek, SPI, FSP and so on you don't relay need to bother with a recap as PP&C used good caps.

I have found a fairly clean 350W AOpen PSU from the early 2000s that has a 30A 5V rail.. It's only 8 bucks, maybe I should just buy it..

I've been using my Ultra X-connect with my socket A build. I've owned it since new its been a great psu over the years and it been rock solid the last two years in my socket A system that gets heavy use from my son with older games and educational software. Its got 28 amps on the 3.3v rail, 30 amps for 5v rail, 34 amps 12v rail, .8 for -12v, .3 amps for -5v, if you can find one cheap there great and fully modular as well.
