Re: Samsung 203b and f301 fuse replacement selection

It was the f301 pico fuse that I see referenced in other threads here(which led me to check it and it is definitely blown). It is green and has 3A and a symbol after it printed on the part.

Thanks for the reply.

Re: What brand are these new polymers?

Thanks! I was just wondering because I ordered a gigabyte p31 board friday with all solid caps hoping for better reliability. If it is a bad board I can send it back when it gets delivered next week.

Re: What brand are these new polymers?

So does using these caps mean that Gigabyte's all solid cap boards should be avoided?

Well it turned out to be a gx240 sff(that may be skinnier but its huge otherwise). The caps look fine in it btw.

Re: Do I have bad caps?

The white residue looks like it is probably an adhesive caulk they intentionally applied to the caps/board to possibly keep them from being affected by vibrations. The bulging caps with the brown residue on top behind the screen are definitely bad....

Re: Bad solder joints and bulged caps, can one cause the other?

I went ahead and replaced the bulged cap with a Nichicon UHE1A222MPD(2200uf 10v) cap. I also changed out the old fans with some Antec single speed fans that I connected directly to the 12v line so they would run at full speed continuously. While I was at it I re-soldered some of the other connections near the area where the bulged cap was located to reduce the possibility of other bad solder joints being present. With the Antec fans installed and running full tilt the power supply is louder than it was, but it is also...

Re: Bad solder joints and bulged caps, can one cause the other?

The Athena 500w was run 24/7 for a little over two years now(first year with no UPS, second year with a Belkin 375va UPS-our power is pretty reliable with the exception of a handful of blinks during storms that are just long enough to cause things to turn off, hence the small UPS). It only started having shutdown problems(while doing nothing but sitting at the desktop) the last few months though(started getting progressively worse the last month or so).

Re: Bad solder joints and bulged caps, can one cause the other?

I would replace the fuhjyyu's too if they were not so hard to get too. The heatsinks on this PSU are horizontal to the PCB and act like a roof(a low one at that) that covers the majority of the fuhjyyu caps. I don't foresee me trying to remove the heatsinks that are bolted down to other components to get to them when the fuhjyyu caps appear fine so far(reputation notwithstanding).

Re: Bad solder joints and bulged caps, can one cause the other?

Yes, both fans(80 & 120) were working fine, although they were temp controlled and tended to run slow so that they would be as quiet as possible. After dusting it out, all of the other components looked like new and showed no signs of anything overheating(no brown spots on the PCB or discoloration anywhere), just one bulged cap.

Thanks for the reply!

Bad solder joints and bulged caps, can one cause the other?

I opened up an [URL=http://www.newegg.com/Product/Product.aspx?Item=N82E16817104123]Athena Power 500w AP-P4ATX50F12[/URL](rebadged topower p4 design) that had been in use for a couple of years to clean out the dust and try to figure out why it was suddenly shutting itself off at random times. I only saw one bulged cap and decided to try and replace it. I got to it easily as it was on the outer edge of the PCB near where the external wires are soldered and when I went to remove it in order to get the value of it(it had glue on the upper half). The cap(2200uf 10V) pulled cleanly out of...

Re: Antec Basiq 500W Pics?

Thank you [B]larrymoencurly[/B] for the pics! It saves me from having to void my warranty.

Would it having active PFC have an impact on the power output with the heatsinks and other components that are used?

I was wondering about that also.Re: Antec Basiq 500W Pics?

Re: Antec Basiq 500W Pics?

I got one in today thanks to the fry's deal that should be only $15 shipped(if the $35 rebate is honored). I thought I would run it for a week or two in a system to see if it dies(in case I need to send it in under warranty for replacement) and if it looks like it is going to be OK, I'll void the warranty and post pics(if I can borrow a camera that is).

Hopefully they will last awhile, although I am worried about the four JPCON's longevity.
