Re: PSU Fortron/FSP ATX-350PNF with problematic +5 & +12V voltages [Factory layed problem confirmed, WORKAROUNDS FOUND]

Posted on 2025-06-05, 05:38

After some more testing it indeed looks like the 5V and 12V rails go more into spec values when there's "enough" load on the 12V rail... On my device it changes from 4.8V/12.8V (sometimes worse like 4.65V/13V) to something in the region 5.05V/12.2V, which is "ok". I think I had it in one or two …

Do you mean that this PSU should work normally only with Athlon 64 x2 or some "newer" P4 based systems? :eyes: I mean, it should work fine for loads inside a closed curve. Outside, it's undocumented behavior. Yep, with the main load of +12V PNF demonstrates excellent voltage stability. Excellent …

analog_programmer: I'm using a new core with "52" material from a specialized "non-cheapo-chinese" (at least I hope so) core manufacturer (https://www.micrometals.com/). Same windings count etc. is intended since the initial assumption was that the core material of the original core could have …

To give some feedback on this topic from my side: I finally got a replacement toroid core (MICROMETALS T130-52), dismanteled the PSU and removed the original toroid (L1 as marked in the schematic in the very first post in this thread). I thought it'd be wise not to damage the original one, so I put …

Chinese PCIe to PCI converter --> With both 1 and 2 PCI slots: https://cdn.rios.hu/dl/upc/2023-09/30/225621_jlhyn75qpoyfwssp_pciepci.jpg The 1-socket RyZen is between the power supply and the HDD bay, the 2-socket FX is above the RAM, and can be placed anywhere due to the long cable. 1Slot.jpg …

... Chinese PCIe to PCI converter --> with Chinese USB3 to SATA cable ... I'm interested in these two adapters/cables. Can you show pictures what exact models these are? I've had mixed results with a PCIe to PCI converter in the past not knowing if it was the adapters or the boards fault. Sometimes …

Re: Socket 4 build (Apr 1994)

Posted on 2025-05-26, 08:03

But this whole Socket 4 project didn’t really work out for me… it’s not particularly fast, and for games from that era that rely on ALU (CPU only, no FPU), it offers no tangible advantage compared to a DX4 just a few months newer, while consuming significantly more power. In fact, with these early …

Re: End of the road gpu for win98se gaming

Posted on 2025-05-23, 06:02

Is this still about the original Win98 system? Or are we talking about a second XP only system now? I think as some others said already for the 98 system the Ti4200 is a good and very reasonable card regarding power, prices, availability and driver support. For a pure XP system, though, I'd choose …

Geforce 4 Ti4200 and Radeon 9600 did fine on Win98SE in my experience, even on a ViA chipset. Also the X700/800 series should do well but may be a bit overkill for socket 370 and are not so easy to get with AGP (and quite fragile due to the AGP bridge chip). I'd go with the Ti4200 or maybe even a …

Re: Switching regulator module as replacement for hot linear regulators (mainly used on PCI VGA cards)

Very nice job. That looks amazing! :-) I added your project to the vrm projects thread. :-) https://www.vogons.org/viewtopic.php?f=46&t=86611&p=1132549#p1132549 Didn't know there was one. Thanks! :D I have an aversion against switching components, mildly said. I rather prefer calm, less efficient …
