^ Could probably have used even 820 uF poly's. It all depends on the VRM design and running frequency. If I see inductors with less than 5 turns of wire each, I know it's a fairly high frequency and will probably take lower capacity poly's fine.

Element14 aren't really known for selling counterfeit capacitors, like say Ebay. I also tested the ESR and capacitance of the capacitors, and they test in spec.

That said, the datecodes are suspicious because they are "reasonably" new.

Since I've already made the repair, I'll keep an eye on it and see how it goes. Should I need to fix it again, I guess I'll be forced to do a polymod.

Would probably be a perfect replacement.

Even counterfeits and low quality caps can test within spec whilst new, though. Element14 still seem to have Nichicon HM in stock. Nichicon announced the discontinuation of the HM, HN, and HZ series in 2012, so Im surprised any of those series would still be in production even as of ~2 years ago, by which point most ultra low impedance electrolytic series were discontinued (except Suncon WG). Articles like this, however slightly dated, are what make me somewhat paranoid about those new HM. But of course, as has been said on this forum before, non-failed caps are certainly better than failed caps.

I'm probably wrong but maybe it's leftover stock from Nichicon? Who knows

Yep, I agree, but at least the caps I put in are working to spec for now.

But I'm not horribly paranoid about it. While Element14 still have little bit of stock, it seems to be a one off as they are selling the last of the stock. Would it be possible that nichicon were simply using up the last of the ingredients over the last couple of years producing a trickle of these capacitors.

Should the new caps fail, it isn't a huge job to recap it again. A pain in the butt though, multilayer boards are much harder to deal with vs single layer boards.

Free scores for last week :

1 - A big lot of new HP laptop fusible plugs , sounds like 30 to forty ones , their fuses are maybe the valuable thing there .

2 - One laptop Toshiba Tecra A9 , without its adapter , 15v , and not working .

3 - One Compaq G62 , not working .

4 - Two Toshiba Satellite A300 , Not working also , lool , but i started checking them and things look different to what it seems .

5 - A big lot of Nvidia VGA's ( mostly 7200 and 9800 ) , not working , with some smd capacitors missing and some polymer bulging . The only one that showed a life sign makes vertical red lines on screen .

Scored a PC today w/ another IP35.

Will check when I get home though, I got it to power on but that's as far as I could do (other than soft-off.) with it due to missing beeper.

My friend got:

Intel i3-3220 CPU
Gigabyte GA-B75M-D3H motherboard
A total of 22gb of DDR3 ram (1x8gb stick, 3x4gb sticks, 1x2gb stick)
Nvidia gtx-750ti
DVD burner
1TB hard drive (only WD green)

For a grand total of $2 AU at the markets. He paid with 50 cent coins.

The only problem with the above hardware was some wonkyness with the motherboard. Someone had damaged one of the memory slots and it had shorted out in the past. There were also problems with the BIOS not booting and the computer going into a power cycle loop. I physically removed the memory slot plastic and cut off all the memory slot pins so they barely stuck above the board (it had 3 memory slots left, it is good enough), and re-flashed the correct latest BIOS and the damn thing works perfectly.

So yeah, he does amazing work finding deals like this.

He did find me an old Pentium 2 board with a celeron 366 on it though, epox kp6-la motherboard with sanyo capacitors, 128meg ram and cirrus logic 5465 AGP card system that he let me have, so I can't be mad at him ... just a bit in awe of his luck sometimes

Today's freebies are 2x Compaq towers that were so scuzzy I didnt want to touch them...but upon disassembling one of them, I test fitted that leftover X7DCA-L I've got....and with a small trim, this oddball mATX board will fit!











...and the last one was a Fujitsu Lifebook t730 i5 @ 2.67 8gb RAM. Dual batteries. OS was trashed and full of crapware. It's a real pain getting stuff to work on this thing....

If it's got a bad socket/socket pin, don't even expect it to bleep at all, just LEDs and fans, likely...

The heatsink was never removed. In fact, I got the PC as the owner left it.

Well, the processor still being installed, usually prevents that type of issue...

Exactly.

In fact, the only reason I got it is because the seller said that the PSU blew. He went to some "pro" (yeah, right.) repair shop and they told him that everything was smoked because of the PSU (which is some pretty huge BS, in rare cases it can happen but smoking a floppy drive would be ridiculous given that it was connected correctly.

Very likely just the PSU blew and everything survived. SB doesn't get insanely hot and board does turn on and off using the power button (if SB was smoked it would get hot when 5vSB is applied regardless of powering on or not) but that's as far as I tested.

Other goodies it came with are a C2D E6400, a Antec 80mm fan and a crappy 80mm fan which was seized (near the CPU cooler, above I/O shield) which I threw away.

The case is somewhat above Deer quality. It's like the Frontier I mentioned a few pages back (momaka might know it, it came with a Deer ) but much more polished - by that I mean the sharp edges were somewhat fixed and I didn't cut my fingers in it. It also features a temperature sensor w/ LCD, although it's probably just for the CPU, since I found only one probe and the sensor doesn't have a 3-way switch either (unlike a Deer/JNC I have which has three probes and a three way switch, which monitors CPU,HDD and "SYS").


Back to the thread, I traded my old Galaxy Core Prime 4G for a Note 4. So far I found out what was wrong with the N4 - whatever stupid shop tried to unlock it not only triggered the KNOX counter, but they also changed the IMEI to a N9109W.

Found this beautiful beast at Goodwill for $2.99
What a deal! These were hard to find in Black, and it's in really good shape. I brought it into work to show off and use as my main work keyboard since our Dell docking stations have PS/2. The <30 year old crowd had no reaction, and the >30 year olds thought it was super awesome.

The sound of the keys is unique and the feedback on it is great. The spacing of the keys is perfect for my hands. Will own until I'm dead. Long live PS/2! I am okay with USB mice, but I haven't liked any USB keyboard as much as my PS/2 keyboards.

Free scores for last week :

1 - A lot of 18 Webcameras Board-x , all working . Spent like two hours to separate their cables , lol ..

2 - One Acer Aspire 7112w 17" , looks like out of a WWIII . Paint is really bad , lot of scratches and keyboard is dusty and greasy , one hinge is broken and there are no inlet power . Just two wires getting out of its hole . On testing , it's fully working . This one has a rotating camera view and since it's 17'' , it's worth reconditioning .

3 - One laptop Lenovo G555 , Without screen . Upon fitting a compatible one and testing , it turns on for awhile and then shut off . I will try another CPU next ..

4 - One Pentium 4 case , it will go for scrap . Goodnight XP..

Got a Enermax EG365P-VE 350W for cheap.

Seized Globe Fans (I thought Enermax wouldn't go that low, guess I was wrong then ) and Hitachi primaries with pretty new PCE-TUR caps on the secondary.

Already gutting it. I don't have any use for it considering I have a Seasonic SS-351HT that is better.

You're looking at $30K... I'm sure the manufacturer has some way of justifying that price!
