Forum Rules *ALL NEW MEMBERS, PLEASE READ!! UPDATED!!*

First and foremost, Welcome to the Badcaps Capacitor Search Engine & Forums!

New members that have activated their accounts have limited access to certain features of the site until established. Members with zero posts have no access to the private messaging system. Also, members with zero posts may not edit certain profile attributes, such as signatures. New members also may not create new threads. However, new members with zero posts have full access to all technical information contained on this forum, and that also includes attachments (images and files that other members have uploaded), and new members that have activated their accounts are free to post replies to existing threads. If you wish to create a new thread, the fix is simple! All you need is ONE post to be able to have full unrestricted access, and that can be simply posting an introduction of yourself or say hello in THIS THREAD. This may seem a little strange, but it helps keep spam and abuse curved. Please note, that it may take up to one hour from your first post for the limits to be removed. If you make a post and don't immediately see the restrictions gone, be patient. The promotion system updates every hour.

Please complete your profile after making your first post, with your name, locale, and other info. It's nice to know members on a first name basis, and know where they're from. Makes for a much friendlier environment!

Posting rules for this forum will be STRICTLY enforced by myself as the owner/administrator, and my moderator crew.

Badcaps.net IS A BUSINESS!!! If you are a servicer, service center, or vendor of any kind in the computer/capacitor industry, you are NOT permitted to advertise, link, promote, or plug your business on this forum in ANY way! NO EXCEPTIONS!! This includes asking for "donations" in exchange for BIOS passwords or tech advice for anything! If I see you doing that, your post will be edited or deleted, and you warned. If it happens again, you will be banned. The only exceptions are the references to the companies quoted in the FAQ which the administration have added for the convenience of those around the world who have difficulty to source caps for their repair.

This also includes using this forum's private message system to solicit business. Members, if you receive a PM from anyone offering repair services or components, please alert me immediately! Myself or any of my moderators, will never private message a user soliciting business, for Badcaps.net, or any other servicer/vendor. If you PM me about repairing your device, I will reply and take care of you, however, I will not message you first.

------------------------------------

Posting rules:

This forum was created to be a technical support forum primarily for the do-it-yourselfers who choose to repair their own boards. Any and all technical questions are welcome!

1) Please use the SEARCH feature!! Your question may have been answered in another thread! Please search first and see if it has!

2) When posting a technical question, be as detailed as possible in your thread. The more information we have about your specific problem, the better we can answer your question.

3) Please use COMPLETE sentences, punctuation, and grammar! Nobody is perfect, hence, a spelling error on occasion is no biggie. However, posts/threads that are unreadable will be deleted. This includes any and all forms of 'ebonics', leet, chatroom jargon, and 'text message' shorthand and slang. This forum is not a chatroom/text message, please use full words and complete sentences.

4) Keep discussion on topic!! DO NOT HIJACK THREADS! It's easy to do (I've done it myself a few times...) Lets try to keep it down to a minimal!! If you have something really off topic, that's what the lounge is for!

5) Keep things civil! There will be no tolerance for flaming, bashing, hateful remarks, racial remarks, adult material of ANY kind, and so on.

6) THE LOUNGE RULES! The lounge is a place for off topic chit-chat! If you post something that might be considered questionable or something you don't want kids to see, or something you can't view at work/school, etc, please label that thread *NWS* or NOT WORK SAFE in the thread title as a warning. The Lounge is NOT moderated, anything is welcome... Feel free to post rants, jokes, cars, hot women (remember the NWS warning in the title), or just about anything within reason. It's an open forum! Please refrain from participating in political topics if you have thin skin, they can get heated sometimes!! Remember that we have members here from all over the world, with many different views and cultures. Political debates can turn really ugly, and really fast, and if they degrade to personal attacks and useless banter/bashing, moderator action will ensue. I want this forum to be a safe haven for technical discussions from all walks of life, so lets keep off topic discussions civil and friendly.

7) Spamming and spammers will NOT be tolerated or accepted in any way, shape, or form! Spam bots are instantly and permanently banned, and their threads deleted! The mod crew is really quick to zap spammers, we typically pop them before they even get to post. This also includes regular members as well. be courteous and not post spam. This includes links to off-site information that's not relevant to the thread at hand. Do not plug other websites, forums, or businesses in your signatures. You may do so in a thread if the off-site link you're posting is relevant to the topic, but otherwise, don't do it. If you see a thread which clearly a spam bot posting that we have not removed yet, DO NOT click any links in it!! Simply click the 'report bad post' button, and it'll be taken care of, usually within minutes.

8) Account removals & closures: Since no personal information is given in the creation of your Badcaps.net Forum account, requests to remove and/or delete accounts will be declined. Any requests for removal of threads & posts you created will also be declined. The reason is the missing posts can/will leave threads incomplete and fragmented. For the threads to be of help to others later on, information can't and won't be missing. However, if you inadvertently posted personal identifiable information in a post (such as an email address, real name, or phone number), please contact a staff member. In those cases, the post may be edited or removed, at the staff members discretion.

That's about it for the rules, the setup here is pretty loose. However, if you're caught violating any of the rules above, here's what will happen:

First offense: Warning by me or a moderator
Second offense: Banning for 1 day
Third offense: Banning for 3 days
Fourth offense: Banned permanently.

If you do something really dumb, or are just a troll, I will skip the warning and the temporary banning, and ban you permanently!

The rules are pretty cut and dry... However, if you have any questions about this policy, feel free to contact me.

    Hey japlytic.

    I have had a Topfield TFPVR5000t since March04. (The Toppy is the best toy EVER, IMHO)
    What is your opinion of the PSU and the caps on it, and the caps on the main board for that matter?
    I notice alot of them are "Sam Young", while the big one is a "Sam Wha".

    I open it up regularly for HD removal/quick-transfer (I've got a WD250 in it) and do a quick visual inspection of the caps each time, just for safe measure.

      I had mine since early 2005. Topfield must have later gone onto the cheaper Samxon capacitors for the mainboard, compared to your earlier one. The components in the power supply were quite decently sized, and has been fine for over a year, despite running a little hot.

      My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

        I've had bought 300W Maxpower/Everpower PSU as a replacement for SkyHawk 250W - but it was weaker and the voltages were bad - so I promptly bought DTK PTP-3007 and sold that crap.

          my 250W Channel Well CWT-250ATX is approximately 12 years old. This PSU is so old, the 92mm fan blows into the computer case instead of into the PSU.

          Primary caps are 470uf Matsushita, secondary side is a forest of Fuhjyyu... not one appears bad. This PSU was in regular use up until a month ago.

            Can't be 12. There was no ATX before 1997 (IIRC). And I see "98" on the transformer.

              I guess '98 would be about right - I only got that unit and a 10gb IMB hard drive a year ago in exchange for a Fujitsu 6.4gb hard drive. It belonged to a friend, who bought the case it came in well before I'd even met him.

              As it turned out, the IBM was DOA so I'm not sure I got the better part of that bargain

                Notice the nice substantial heatsinks on the Deltas (and O/P trannies) and the Sparkle? Ya gotta keep the junction temps on those O/P rectifiers and power MOSFETS (possibly power transistors in the Sparkle) within reason. The power ratings are real on those.

                  Did you also notice what appears to be a large burnt spot on the above Sparkle? I only noticed it after I posted the picture here... As far as I know, the PSU is still operating normally.

                    Was it caused by the larger resistor that's standing up? Because in either a 300W or 350W Fortron/Sparkle, I found that such a resistor was dissipating almost exactly its max power rating, either 5/8W or 1W. Aren't resistors supposed to be rated for at least twice their operating power?

                      Re: Power supply build quality pictorial

                      Yes, I did see that. It looks like a 1W or (more likely) 2W. It could be disspating its rated power or a bit more, or it may simply be mounted too close to the PCB. Normal design practice at places I've worked at was to mount resistors 1/2W and higher spaced off the PCB to avoid scorching the board. Good design practice would be to use resistors at ~70% or less than their reated power (taking into account the operating ambient temp. US mil-spec requires 50% max.

                        Since there is no ugly integrated-into-PSU-case fan grill on that, does it use a removable wire fan grill?

                          Nahh, it was just for fun... And to have an emergency extra PSU at hand...

                          I already recapped it, See here...

                          The missing fan was because I put a 92mm fan in the bottom of the PSU instead, to reduce noise. And because the 80mm one started to fail and I had a 92mm one just on my bench

                          That PSU came from a real cheap case, has powered a friends comp a few months before he got a real PSU, and after that my brothers till the caps failed and it would no longer turn on...

                            FSP700-80GLC power supplies as research have shown are 700W power supplies.
                            Maybe they used the board for the FSP700-80GLC but changed the components?

                              Probably. The protection circuitry board is also marked "FSP700-60GLN." Not that I need the extra power

                              The OST caps worry me a bit though.
