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.

    Seasonics are always good, will provide many more years of reliable service.

    I wouldn't worry about it.

        Whenever I recap a psu, usually I just replace all the 16v caps with 16v, 2200uf. Sometimes they will have 16v, 1000uf, or 16v 1500uf's. Just make sure they are not some weird diameter, usually 16v caps are 12.5mm, and will fit most psu's, except for those CWT antecs. Also, there is usually a 16v, 470 or 680uf, replacing that with a 2200uf is a waste, as this is just for the -12v rail.

        Then 10v caps usually do the 5v and 3.3v. These are usually 10v, 2200uf and sometimes you may find a 10v, 1500uf. I just replace all 10v caps with 2200uf's. Again, make sure they are not some weird diameter, usually 10mm 10v caps will fit most psu's.

        Then there will be smaller caps near the smaller 5vsb transformer, usually 50v, 47uf that filters the 5vsb. Replace that to avoid a high running 5vsb.

          Re: Power supply build quality pictorial DISCUSSION

          For the 3.3v rail, 2x 2200uF caps should be used as a minimum (or bigger if you have the space). You can use either 6.3v or 10v rated caps. I, however, prefer 6.3v to the 10v caps since they're cheaper and in some cases might last longer than 10v caps as the oxide layer is better preserved if the voltage is closer to the caps' rated voltage (at least that's what I heard from a few people here).
          For the 5v rail, 2x 2200uF should be used as well. Again, both 6.3v or 10v rated caps should work, but I think it's probably better to use 10v caps.
          For the 12v rail, 1x 1000uF 16v should be absolute minimum, and that's only if the power supply is used with an older 5v-based system (such as PII/P3) with 1 hard drive and minimum hardware. If it will be powering a P4 or some newer 12v-based system, consider 2x 1500uF to 2x 2200uF as a minimum. Most cheap power supplies only have space for 10mm dia. caps so those sizes might be hard to find. But if there's space for 12.5v caps, try 3300uF.
          For 5vsb, 2x 680uF should suffice, but it would be much better if there is 2x 1000uF (again, either 6.3v or 10v caps will be fine).
          The -12v and -5v (if present) usually don't need more than one or two small caps (in the range of 220uF to 680uF).

          One thing not to forget, however, is that ESR and ripple-handling capability ratings are much more important than the uF rating. Of course ESR depends on the can size of the capacitor, so the bigger the capacitor, the lower the ESR (which usually also means that the uF rating will be larger). Just avoid getting general purpose capacitors that mgiht meet the uF requirements but are not low enough on ESR.

          That's only if the power supply uses a 2-transistor design (the capacitor that 370forlife mentioned is actually used to control the 5vsb, hence why it's so important). This thread should help you identify if your power supply has it or not:

          Also everell's threads on the Bestec ATX-250 12E might be helpful as well.

            So id expect that my 500w Dynex PSU is no better then the 400 or 250w PSU they sell and just whaat do i need to recap it?

            and how do you save your shortcuts from FF the faves stuff whare is it stored?

              Whoops, I forgot we were not talking about el-cheapo psu's with undersized caps here.

              I actually just took apart a sploded hipro today for parts, and the 16v caps were all 3300uf. Immediately thought of this thread.

                  looks a lot like a "eagle" that a customer brought in with his new i7 build that would not post.gutless wonder.a real 300w hipro from a dell ran the i7 just fine.

                    I like the fake UL certification on the side, just UL in a circle.

                      Re: Power supply build quality pictorial DISCUSSION

                      Can't say for sure, but it does look goofy with that fake UL like 370forlife noted. Only pictures of the inside will tell how good it is.

                      I also just noticed that sticker says it has "over-power" and "overload" protection. Technically, wouldn't those terms mean the same thing?
                      One thing that is certaily true on the sticker is the text that says Made in China.

                      But on the positive side, you get a PSU case with a 120mm fan. Means if the power supply is crap, you can put a nice power supply in there and take advantage of the 120mm fan .
