Note, I don't know if it's proper subforum or should I post in PSU one.
I am looking for schematics for two ATX PSUs: Seasonic G360 and FSP-350GLN.

PSU: Seasonic G360 and Fortron FSP-350GLN

Re: List of pin compatible pwm/supervisor PSU ICs
I don't know if these are completely same but I've noticed their datasheets are identical(copy-paste) - HY510N and EST7610. I have also compared HY510N and WT751002 datasheets and found that the only difference are PDON_N pin Voltages: 2.0V/0.8V on HY vs 2.4V/1.2V on WT.
It looks to me like either companies behind these have some agreements or they literally steal from each other.

Re: FSP-350GLN(80) not booting mobo properly
I still didn't do any comprehensive test, but as it turned out, perhaps I might not need to. This is fifth day I'm using Seasonic G360 PSU on this PC. Not a single problem. Fortron 350GLN is also working fine. PWR_OK on both PSU's is at around 5V, stable. Odd, as both PSUs seemed to be malfunctioning? Perhaps not.
My conclusion is, that there was something shorting PWR_OK pin on motherboard. I've tried cleaning case and motherboard multiple times and analyzed PCB traces but found no oddities. Maybe it was some sort of gunk...Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
I am still pretty busy with other things but for all that time my FSP-350GLN is working fine with motherboard. It's currently Seasonic G360 that is causing issues(exactly same as FSP before), so perhaps topic name should be changed to reflect it.
Nevertheless I got new multimeter but I don't have time to do more extensive tests yet. Moreover it's not only multimeter but general lack of proper tools that is holding me. I don't have proper lightning, magnifiers, accurate soldering guns, neither high-resolution camera to post...Last edited by tartuf; 01-12-2023, 06:58 PM.Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
I couldn't resist, so I took my barely working multimeter and found out that 2000 Ohm continuity test works(every other continuity test is broken including buzzer one). And then I have decided to follow the PWR_OK trace and it led to smaller PCB board soldered to main PSU PCB board. Then on this smaller PCB board I found 8-pin HY-510N(538 J69A3G) element. It's PC Power Supply Supervisor, essentially responsible for PWR_OK checks. Datasheet is here: [URL="https://z3d9b7u8.stackpathcdn.com/pdf-down/H/Y/-/HY-510N-HawYang.pdf"]https://z3d9b7u8.stackpathcdn.com/pdf-down/H/Y/-/HY-510N-HawYang.pdf[/URL]...Last edited by tartuf; 01-08-2023, 08:16 PM.Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
Forgot to add that at some point I've decided to test Seasonic PSU in PC again, just with 12V fan as bypass launcher. It worked and everything booted normally. I have successfully stress-tested PSU under Prime95+, Furmark, etc. load and all Voltages were very stable. Everything worked perfectly fine. But next day I have tried to boot PC using 12V fan as bypass and it didn't launch at all. I've noticed that PWR_OK is still 0.6V even with fan connected and running. I've also tried adding more load, ie. more fans, DVD-ROMs etc. but it didn't...Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
Thanks, I paused this for a bit due to more important things. Also, accidentally I dropped my multimeter and it ran out of range and is showing unrealiable results(like scale would go down to lowest digits), so until I swap one or fix it there will be no progress. And the picture I posted was generic one I found on internet, it's not mine. If(when) I will find more time I will send some real pictures and more multimeter readings. But the bigger problem is, if this Seasonic PSU has some issues then I will still need to replace proper components...Last edited by tartuf; 01-08-2023, 01:51 PM.Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
My Fortron is still running MSI motherboard well, so I have decided to delve deeper into Seasonic G360.
I have disassembled it to inspect PCB, it had untouched warranty sticker so technically I was first person to open it. I didn't really dig deep, on surface everything was fine but I still cleaned it with alcohol. All caps looked fine, nothing bent nor oxidized.
On the bottom side of PCB, in one place I found some small area where it looked like there was small leakage of something but I've cleaned it all areas...Last edited by tartuf; 01-04-2023, 03:25 PM.Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
To add about odd PWR_OK behavior on my Seasonic(and probably Fortron too when it's playing dead):
When I connect PAPST 4112GX fan which is around 6-7W on 12V(and I can connect it to any 12V, not only molex) the PWR_OK almost always goes to 5.04V from 0.669V. I wrote always, because out of around 100 tries maybe two times it didn't work when PSU was already running for like 10min. It always worked when PSU was being cold-booted with fan already attached. Now, when it works I can disconnect fan anytime and leave PSU running...Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
I found some multimeter(had to fix it first) and made some testing with it. I do believe that results are very promising. I've tested four PSUs and MSI motherboard(Ohm test). Didn't do short-circuit test and didn't test capacitors but can do it later.
Here are the results, first motherboard 24-pin and 4/8-pin Ohm tests. Note I had to use 2000 Ohm setting instead of 200 Ohm setting as my multimeter is still not working 100% properly:
24-pin atx:

Re: FSP-350GLN(80) not booting mobo properly
I might get access to more computer parts but it will take some time.
But even if new PSU would work upon first launch, what are the chances it will work all the time? As this issue is pretty much random and I am sometimes able to boot my PC properly using any of my PSUs(except for one FPS that doesn't work with MSI) just to find out that after few days they can't pass CPU LED test... and then few days after this such failure they work again.Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
I did more extensive tests.
First of all, MSI B250M Pro-VD, the one I'm trying to get to work, does have some beep option in BIOS but it doesn't work. I've connected old speaker to mobo audio output and there is no effect. But it also does have "MSI EZ Debug" which are four LEDs(CPU, DRAM, VGA, BOOT). I kinda think it totally sucks and is horrible btw. How it works? Well first it lights CPU LED and when everthing is okay, it lights DRAM LED, when everything is okay it lights VGA LED and finally BOOT LED. Then when...Last edited by tartuf; 01-01-2023, 03:44 PM.Leave a comment:

Nope, no booting. It's all same(actually it boots except for PS2/USB/monitor).Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
Actually my CPU is Intel Pentium G4600 with HD630 iGPU. I have unplugged my dGPU, Nvidia GTX 1060 3GB completely and connected iGPU but result was same as with dGPU. Tested on every PSU.
Albeit I will do test this more extensively when I get more time.Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
There's another thing, when testing PSUs with that old Dell PC I've decided to test my second FSP-350GLN(80), one that never worked with MSI board and only passed paperclip test. To my surprise it works with Dell(Foxconn G33M02 mobo). But that's another hint at MSI mobo malfunctioning and not PSUs...Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
Cleared CMOS, no change. Disconnected discrete GPU and switched to internal but it didn't change anything. Did few more tests and got some findings:
I found some old Dell PC that had original BIOS(not UEFI). Noticed that when it boots, it first spins all fans, then beeps("all fine") and then powers up USB in that order. Decided to test FPS PSU's against Seasonic. Old 200W noname PSU that came with that old PC worked fine: fans->beep->USB power; both FSP PSU's worked fine: fans->beep->USB power; Seasonic...Last edited by tartuf; 12-31-2022, 10:05 AM.Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
I got latest BIOS(UEFI) and for few years it worked fine. I will flash it next time it happens but for now more oddities came. As for battery, it's brand new - purchased like week ago. Old battery is also fine, just tested.
As I said, I've been using this mobo with FSP-350GLN(80) PSU without issues for like 2 years. Then out of nowhere(no hardware/software changes) "no boot" issue started to happen. Everything boots and I can hear fans and disks running except for PS2/USB/display.
To test FSP PSU, I...Last edited by tartuf; 12-31-2022, 08:38 AM.Leave a comment:

Re: FSP-350GLN(80) not booting mobo properly
After swapping PSU I have noticed that issue is still there, indicating that it's not *only* PSU. With old PSU I had to use power switch like 3-10 times before PC properly boots, with new PSU I have to use it 1-2 times.
Anyway I wonder what else could cause such issue. Dying MOBO(MSI B250M Pro-VDH, like 3 year old), GPU(Zotac GTX 1060 3GB, 3-4 year old)?Leave a comment:

FSP-350GLN(80) not booting mobo properly
Greetings
My old 350W FSP-350GLN(80) PSU was working fine with my current computer for few years(and previously with few other computers as well). Nothing has changed in setup but since last few months I am getting problems while trying to boot PC.
What happens, is that PSU starts and I can hear fans, both PSU, CPU, MOBO and GPU. I can also hear HDD scratching and normal starting sounds. But DVI monitor claims that there is "no signal". Moreover, neither USB mouse nor PS2 keyboard does flash leds like it should do upon boot.
I have to turn PSU switch...Last edited by tartuf; 12-23-2022, 11:35 AM. -
