Re: PC Randomly Sleeps And Cant Be Woken

I'm putting my money down on a config issue with Windows 10.

Make yourself a bootable live Linux DVD or flash drive (pick a distro that seems easy to use), then try it. If PC doesn't go to sleep...

Re: Black plastic goo question.

Can we get a picture of said devices.

I too have only seen electronics with rubberized coating "leak" / smudge like this.

Most plastics start to melt only past around 120C (250F). So I don't...

Re: SuperMicro Board Issue

Yeah, I was just about to post, what you got against FSP PSUs? :D

Then it crossed my mind perhaps you were thinking of Powmax, which is indeed only trash-worthy :trashcan:

Yep, Powerman / FSP /...

Re: Must this Nuvoton NCT6793D Super I/O IC be programmed ?

If that's the case, check Vcc supply to the Super I/O (typically 3.3V either through a MOSFET or a linear regulator generated from the 5VSB.)

It would best to do this once you remove the Super I/O...

Re: Dell optiplex 960

I see mostly Rubycon and Panasonic caps around the board, so those should be OK.
However, I do also see two green Sanyo/Suncon caps. If they are WF series, you might want to replace them. WG = okay....

Re: Overclockable Dell computers.

I see I'm not the only one then that keeps an eye on the better Dell heatsinks. Whenever I see a good one for a low price, I'm tempted to buy it. Good heatsinks are always worthwhile getting if they...

Re: The Hall of Shame - Badcaps Photo Montage

Yup.
Caps with unstable electrolyte tend to do that, especially shit caps from China.

Good Japanese caps can sit for a few years on the shelf without use and have no problems afterwards. Of...

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

If the 12V rail is produced by superimposing a 7V rail on top of the rectified 5V rail, then in such arrangement, both the 12V rectifier and 5V rectifier are used when current is being pulled from...

Re: Task TK-940TX-DF Blowing fuse

So did you try measuring the voltage across the two big caps when the PSU is plugged in and the bulb glowing?


Yes, that will be fine. Let's see what results you get above for the voltage across...

Re: Dead Asus P5P800-VM

Nice work! :)
Glad to hear you were able get to the bottom of the problem and fix the motherboard. I honestly didn't expect the PWM controller to be bad.

Re: Panasonic FC series - leaking? quality gone?

I've used Nichicon PW in some PSU repairs, and so far so good.

I am still a bit weary of some of the Nichicon entry-level caps, though. For example, I had genuine (from Mouser) Nichicon PM leak...

XFX GeForce 6800 XT AGP with modded cooler [WIP]

I don’t think this is going to be a surprise really, but my (practically) never-ending supply of Xbox 360 rev2 (1 copper heatpipe) CPU heatsinks has come in handy once more. Since the 2nd 6800 XT had...

Re: Very old Sanyo OS-CONs. Safe to use?

Corrected that for you. ;)

Well, at least I would gladly use these over GSC / Evercon / Sacon FZ and Rulycon (fake Rubycons, no surprise). Heck, these might be better over a lot of other junk...

Re: Very old Sanyo OS-CONs. Safe to use?

So what's your short answer then? :)
Use them? Don't use them? Try them.
I'd say try with caution. Or better yet, first charge to full voltage and check leakage current. If all is well... let's go!...

Re: $20 "500W" PSU From MicroCenter, how bad can it be?

Yeah, a lot of our PSU experts/fellas are gone now, or at least not on BCN anymore is what I mean.

Re: Short on motherboard Gigabyte GA H97 Gaming

Most likely the motherboard has a shorted MOSFET on the CPU VRM (probably an upper MOSFET.) Either that or something wrong with one or more of the MOSFET driver(s).
