Yeah, like I do want to replace the capacitors in the good working PSUs, or at least some of them, and maybe the big large awkward non-AT/ATX form-factor units some old machines have...

But I'm seriously thinking going ATX -> AT is the way to go, while yes, I'll lose the -5v and -12v rails, but those can also be restored if needed. Some of my audio cards will require -5v, as possibly would some networking cards... but that's not a big deal.

But from what I've seen, I'll want to fuse the 12V rails, because of how much current our modern PSUs can deliver, the safeties won't really catch any real problems, like say a shorted capacitor... but if I fuse it to say what a typical AT PSU is rated for, fast blow, I probably could give them reasonable protection.

What do you think about this route? I could always go for some of the industrial grade PSUs, but that's certainly more money.

Sounds like an excellent plan! Are you going to use the Traco parts I talked about to produce the negative voltage rails? What about the PS_ON, will you wire that to an AT mains power switch?

For the negative voltage rails, I'm not certain yet, but one option is I've seen mini ISA cards cards you can get with voltage regulators on, and insert those to restore the negative voltage rails for either the 5v side or even 12v side at the same time. Since those usually are not rated for high power, that is a solid solution I could always consider. Assuming the rig isn't fully loaded down with add-in cards, of course.

Worst case is using the solution you used.

As for the PS_ON, I was just going to use one of these ATX to AT adapters that will take care of that:

Ah yes, those things clip right onto the old-fashioned power switches. Cool!

And yes, of course, an ISA card could do it, since the rails aren't exactly directional – the motherboard doesn't care whether the voltage is going from the PSU connector into the ISA slot or the other way around! Actually, with that in mind, a PCI card could also do what I did a few weeks ago!

alright. so im completely lost at the moment.

So, my pc has been using 10Gbs out of 16 GBs of ram. i am only running firefox, task manager nitrosense and resource manager. i dont know whats going on, people tell me to reinstall windows but i dont wanna lose my progess in RO, webfishing and PVZ.

Any tips? i can provide screenshots if needed.

How many tabs have you open in Firefox?

i just checked, about 15.

Yeah, browsers can use a lot of RAM when you've got lots of tabs running! Try closing a few and see what happens!

that only lowered it to 9Gbs.

When you have a lot of memory, Windows uses it for caching applications.
This is a good thing, not a bad one. Your programs may start faster.
If a program needs a lot of memory, Windows will purge the least recently used stuff from the RAM.

yeah but webfishing lags a lot unless i close literally everything. i literally just wanna fish...

It sounds unusual if that's happening on a fairly powerful device. I haven't ever noticed any slowdown on mine even if I open about 20 tabs and have Visual Studio running etc.

I have shown my pcs specs. The CPU and GPU are completely fine. They only go to about 20%.

My brother brought up that maybe the ram isn’t plugged in or wired correctly. Should I get it checked?

Yikes… GMP damaging Zen 5 CPUs?
I feel like chalking this up to a thermal issue is naïve… More likely it's an electrical overstress issue of some kind. Though if TSMC did the wafer-level reliability properly and AMD followed the design rules, that shouldn't happen… I'd love to get a damaged device under the SEM and see wtf is going on

So is the problem just that Webfishing is slow? Or is everything else slow too?

That's wild... but yeah, I mean there's gotta be something more to simple thermal issues, right?

So I decided to look into the power supply situation further, as I may be able to get away with a modern ATX power supply into an AT system, if I avoid Corsair, since Seasonic for example, seems to still support the -12V rail. From my understanding from one of your earlier posts, serial ports, aka RS232 rely upon this usually, yes?

Since I do often need to use a serial mouse on these old machines, the lack of that rail would be a bad idea.

And depending on the add-in cards, I may or may not need the -5V rail, which can easily be restored by the methods I mentioned earlier or a similar to what you're doing method.


Also something I feel I need to clarify on:
I've also come to realize that earlier on, when you spoke about your negative voltage adventure, I cannot find the post to reference, but I realized I had initially confused the -12V rail with the -5V rail initially. Since I thought only some of the old ISA cards, like audio, networking, etc that did need it, would be missing it with a modern PSU. Except now we're in the same boat over the -12V rail from some manufactures, it would seem.



Either way, my new adventure begins with the ATX to AT adapter I posted about earlier. Now, sadly I do not have the resources to easily get my hands on one of these fancy adapters.

That being said, the reason for concern is the mere fact we're dealing with a high amount of current capabilities on the old PSU's, at least on the 12V side. Really not much has changed in the 5V realm, as PSU's then and now are the on average the same, but for example, one of the PSU's in my 486 rig can supply 8 amps max, where a modern PSU can easily reach 50+ amps... so obviously in the event of a short circuit, such as a shorted capacitor, well... more than likely the copper tracing on that motherboard is going to go up like a fuse since there's no way this low of a current will trigger an over current protection on a today PSU.

So I'm thinking the next best route is the small automotive minifuses, since I can get those in a fast blow. Something nice and small such as this 5amp fuse. I can either find an in-line fuse holder and solder the wires together, and size the fuses to what the motherboard probably *could* pull max, with a few add-in cards, or even do a small automotive fuse block if that would let me fit those in place as well, such as this style by Eaton (BP/FB4-ATM) which would allow me to cover the 12V line and even fuse the 5V lines each as well for added protection there. 'cause you never know!
Now we probably can assume the 5V rail is going to have a greater load on it, without a doubt on these old systems... Especially given how many dedicated wires there are for them each:


What do you think, PluM?

Shure I got them mixed up too, as mentioned in the footnote on my blog post, which is why I wasn't careful about getting a PSU with the –12 rail in the first place

What a beautiful device! This makes me wish even more that I'd saved some of my old AT hardware, just so I could try this out €49 + shipping, not too bad I guess?

OK, so that'll blow after 350 ms at 10 A, similar to the "slow blow" mode on the "fancy adapter", even if the fuse is called "fast blow". Makes sense"

I guess, since the CPU is probably hooked directly to 5 V instead of a regulator on the 12 V line…

I think it's gonna be awesome!

Here are the case badges of my OC Reese I had made for my retro systems, especially the towers that didn't have any case badges on them already:

They are now compatible with Reese!

Looks great! When is ReeseOS releasing?

Computer stuff, I got my new mousepad in!

When you program it for me and make it look like Windows 3.1.
