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.

      Re: Power supply build quality pictorial. part 2

      hey guys, shouldnt we be discussing in PSBQP DISCUSSION? or maybe even a new thread, since this is more of a recapping discussion and not a build quality discussion. just something you might want to think about.

          BACK TO MORE PICTURES................................

          Antec PP-303X...............looks like an AT power supply retrofitted with a piggyback 5vsb pc board. Transformers are labeled with CWT - so I guess it was subcontracted to them.

            Also the CWT-300 blah blah blah Channel well at the bottom of the label kind of gives it away.

                In my opinion that actually looks like a decent power supply. Just add the input coil and two X caps that it has places for on the PCB, along with a recap, and it should be a reliable power supply for a lower-end computer with a Celeron Dual-Core or Athlon II X2 processor (if it had the 24-pin ATX connector).

                It doesn't look like a 450W power supply, but it isn't a bad power supply.

                  Doing it to actually save money or something is just stupid, you just wont

                    I improve the power supplies that I already have if possible, I get the input filtering components from old power supplies right now (X and Y caps aren't that expensive though), and aluminum electrolytic capacitors are cheap components.

                    The importance of the computer power supply I understand is high, that's why I have a well-built power supply in my main desktop PC.

                    kc8adu's Power Up! power supply definitely looks better than my L&C power supply before I did anything to it (this photo was from the Internet, but this was exactly what my L&C power supply was like):

                      Show your improvements to this L&C.

                      Long ago, I used to gather up old PSUs and improve the ones that is deemed decent enough with parts salvaged from others. I still do.

                      Cheers, Wizard

                        I already did in this thread: https://www.badcaps.net/forum/showthread.php?t=7530

                        The improvements:
                        1. Replaced two 3A FR302 diodes on +12V rail with STTH2002CT 2x10A TO-220AB diode
                        2. Replaced all secondary and small capacitors (2.2uf and 47uf) with Panasonic FM and FC replacements (the 1000uf 16V cap on the +12V rail was increased to a 2700uf 16V cap)
                        3. Replaced cheap 330uf 200V primary caps with Nichicon PW series 470uf 200V caps
                        4. Added X cap and coil to input filtering
                        5. Replaced four input 2A diodes with 10A bridge rectifier
                        6. Replaced cheap fan with Sunon EE80251S3-0000-999 80x80x25mm 12VDC sleeve bearing fan
                        7. Added two inductors to secondary side

                        The finished improved L&C power supply:

                          even though it looks ok as in no blown caps,ect it would not run my neighbors e2200 dualcore box reliably.hangs and bsod were several times a day.
                          i put a bestec 300 in it that i recapped.
                          that was 4 days ago.it has been on since with no issues.
                          this unit is a pile of shit.

                              I agree somewhat, though I have to say that it also comes down to how much time you have. If you do have the time and scrap parts, it probably is worthwhile. It's the greener alternative too vs just throwing the PSUs in the trash where they can contaminate groundwater.

                              If you lived closer, I'd gladly take them all. One man's trash (or in this case, a "pile of shit"), another man's treasure .
                              You should put them in a pile labeled "free, as-is" next to your shop . I'm pretty sure there will be some people to snatch them.

                                the junkers get stripped of parts when i need something fast and no time to order.
                                any i toss get recycled.the junkers around here are on constant patrol and any scrap gets picked up fast.

                                  AGI BPS 2504-4U 250W AT power supply
                                  I just recapped this one (got to school a week before class and I have nothing better to do)

                                  Before the recap overhead shot:


                                  Before the recap secondary side:


                                  Picture of the new caps (and the ones they replaced):



                                  The cap replacements were:
                                  +5v:
                                  2x JPCE-TUR 2200uF @ 10v -> 2x Nichicon HE 5600uF @ 10v

                                  +12v
                                  JPCE-TUR 2200uF @ 16v -> Nichicon HE 3900uF @ 16v

                                  -5v & -12v
                                  each 1x JPCE-TUR 470uF @ 16v -> Panasonic FM 680uF @ 16v

                                  Line Filter:
                                  Empty X spot -> 0.068uF X2 that I found in my basement


                                  Primaries are NCC SMG 470uF @ 200v

                                  After the recap secondary side:


                                  Overhead view after the recap:


                                  Pretty good little psu, I use it for testing things mostly. Years and years ago I replaced the fan. I wasn't having any problems with it, I was just bored and decided I could use the practice.

                                      I actually had one of these that came out of a old Quantex QP5 pentium. I believe it is a bestec, as thats what the UL on the label led to for me.

                                        Is that an LED fan?

                                          And it had the exact same transformer that my old AT AGI 300W Hipro had in it.
