Arrow KDMPower MIPC MI-X8775CD: assembled with input filter (v1)

OK, so I was cleaning up some of my other open/unfinished projects the other day and decided to put this KDMPower PSU back together too. Surely I could solder the input wires and slap it shut again....

Re: Ultra 350w ATX Power Supply

Looks like a Young-Year PSU (and probably is, since Ultra did use that OEM for some of their modular series, if I remember.) Though, it could also be (and likely is) a WinTech, judging by the "WIN"...

Re: Topcat's Other Misc Weird Build Thread

Man that sucks for sure!


Yeah, I was about to say, wouldn't it be possible to still sell the system without the touch screen?
If there was no non-touch version, I probably would have attempted...

Re: Gigabyte EP43-UD3L stuck in POST

Is this board powered from the Antec PSU you just posted about recently with bad 5VSB? If so, maybe the PSU just has more bad caps. Also, being an Intel board... any chance you are running a stock...

Re: Modding Two PSUs to Output 12V

Yeah, when working on PSUs - be it modding or just probing voltages - always have it plugged in to a series current/power limiting device, such as an incandescent light bulb or two (or a more...

Re: junky Jetway P4MDPT board

Yeah, monitor PSUs use flyback topology, so caps with high ripple current specs would be desirable. Probably better to slip in a few more Nichicon HD 680 uF in there in place of some of the VYs, as...

Re: The (now the death of) Dolby DP600 Build (OK, this one is BEYOND COOL)

Lol! I sense this will never get finished if you keep getting more/new parts. :group:


I see you found a small TFX PSU for the machine I sent you. Well, I promised I'd look for a matching PSU...

Re: Topcat's Other Misc Weird Build Thread

Wow, that looks pretty bad. Perhaps this was in a basement or some other low area that got flooded? The "water line" on the corroded base seems to indicate so... though it could also have been a...

Re: Drilled motherboards

If the motherboards have an SSD or other storage soldered onto the motherboard (such as tablets and many of the modern ultra-thin laptops), then that's probably the reason why... which is silly,...

Re: Cap availability problems

Rubycon YXJ and ZLH series are also available in that size.

I like the YXJ for entry-level low-ESR, like replacing those Teapo SEK caps. Such entry-level low-ESR caps are usually employed in PSUs...

Re: Need ASUS Capacitor KZG 16v 1000uf

For PC motherboard use, no, this wouldn't be a problem.

Those 16V 1000 uF KZG caps are typically used to filter the 12V rail for the CPU VRM. So if yours are somewhat close to the CPU heatsink,...

Re: Asus A7V8X hdd issue

Yup, that's a classic failure mode for KZG, especially those 3300 uF ones: capacity goes through the roof and much higher than the 20% allowable spec. This is a sign that the capacitor electrolyte is...

Are you missing the same two capacitors? If not, please state what other issue(s) you're having with your card.

Also, front and back pictures of your video card would also be very helpful so we...

Re: Corsair AX850 low 12v and 5v voltage with random reboots.

Congrats on the fix, Psychedelic!

Where was the faulty cap located and what kind of cap was it? SMD? Through-hole? Just curious to see if this could be some kind of wide-spread failure or just a...

Re: Modding Two PSUs to Output 12V

I hate to be a negative nancy, but I don't think these mods will work too well (if at all), because you're trying to change the voltages a bit too much. The reason I say this is because the main...

Re: Corsair ax1200 hard short

Unless llonen or someone else who has this PSU (and has it open on their bench) can provide these values, I think the best way to figure it out is to find a datasheet for all of the ICs on the...

Enermax Liberty ECO 400W [ELT400AWT] primary cap check and mods

Since people here (and I myself) were curious about the condition of the primary cap, given the “strange” noise the PSU makes when it initially powers up, I decided to pull it apart and check that...

Re: Asistance required on troubleshooting Corsair CX500

*sigh*

Another of these POS APFC circuits causing trouble again.

My #1 tip would be to use a 450V-rated primary cap instead of 400V (or maybe 420V if you don't have any 450V ones or they are...

Re: the gutless, bloated, and fried power supply hall of shame

Re: junky Jetway P4MDPT board

Based on the pictures you provided of your PSU, I think it should be possible to squeeze a 10 mm cap in that spot if you let the cap sit raised about 2-3 above the PCB with slightly longer leads and...

Re: Enermax Liberty ECO 400W [ELT400AWT] - from scraped to serviced

Good catch!
I guess too late editing the tittle now.

However, I do wonder how much more different the "ECO" version might actualy be (if at all) inside from this non-ECO one, then. I don't think...

Re: best cheap/free scores 1.1

Doh! :duh: Of course, why would TC drive all the way to you and then both of you drive back to his place? Makes no sense indeed... but my mind's brain farts sometimes can't be helped. :D


Nice!...
