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: the gutless, bloated, and fried power supply hall of shame

    The UL Number on the PCB (E171766) points to Fai Wong Electronic PCB Co, but they are just a PCB manufacturer, so that doesn't tell us much about who actually assembled the PSU (maybe that's supposed to be Fail Wong Electronics )
    The UL number on the case (E161870) returns no results at the UL database, so it's possibly forged.

    I must say, though, that green logo on the transformer looks familiar to me. I can't remember where I've seen it, though.

      Thanks for all your info. My friend paid 150000 vn dong (about 7 USD) for it, don't know how much power it could supply.

        Looks like the transformer is so tiny, I bet it will saturate and blow the switching transistors before it reaches 450 watts xD

        Atleast the heatsinks are somewhat decent, not just thick hunks of metal.

        I wonder if those primary caps actually read 330uF, or if they read 220uF xD
        Any way, those are tiny for a 450 watter.

          Yes, the transformer is very very small, it is smaller than the one of my Pen II Dell 200W PSU.

              450w !? You're lucky if that psu goes over 200 watts ! )

              Those rectifiers on the secondary side are rated for 16A and 12A ... so it might do 3.3v @ 16a =53 w , 5v @ 16a = 80w , 12v @ 12a = 144w ... but the transformer itself is designed for 150-200 watts ..

                Re: the gutless, bloated, and fried power supply hall of shame

                I'd give it 200W without blowing up, but given how little output filtering it has, I doubt if it would be able to deliver anything at all with the ripple in spec.

                  Yeah, I inferred the 450W from the label. Ofc, they always lie about the wattage rating

                    Fix the fan controller? What fan controller?

                    These things are designed to run the fan on 12V all the time so they don't overheat. That's why the sleeve bearing fans in cheap power supplies die so quickly. Most of the time there's nothing wrong with the cheap sleeve bearing fans. A ball bearing fan will sure last longer but then the PSU will get filled with dust quickly and it will eventually overheat anyways. It's really best for them to have put bigger heat sinks and bigger parts - then the fan can be slowed down... But that costs extra $$.

                    Exactly! Who cares about raw output power if the PSU's ripple is in spec only for a fraction of the wattage it can do.
                    With those tiny caps and inductors on the secondary, I'd say about 50W is the MAX usable power you can get out of it before ripple and noise go out of spec. I had a cheap L&C with a similar cap configuration on the secondary and it couldn't even power a 400 MHz Pentium II (24W TDP, 33W max) PC under full load! And all that computer had was a low-wattage S3 Savage 4 8MB video card and a single low-power Seagate HDD.

                      Check out this "Newegg special" piece of shit....When I opened the case I got a strong smell of burnt silicon and the classic smell of overworked electronics. It was powering a Core 2 Quad 2.33GHz, 4 sticks of RAM, 1 HDD and a 7600 GS. Pretty low load to be honest. Primary caps are Fuhjyyu and the rest are BH. At least they used Late Yoon fans, but the thing was annoyingly loud. Only two 1000uF 16V caps for 12V filtering

                                I keep almost everything. Bit like ant, dissect it into small pieces every time You can use input caps for 250W PSUs, NTC when it blows somewhere, toroids at least for cores to make replacement (if you posess inductance meter). Resistors and stuff are also a need from time to time

                                  ^ Crappy caps / lack of output filtering aside, that Logysis is not that bad. My friend has the "480W" version at his repair shop - now that one is a big piece of shit. It cross-loads very easily and even hisses/squeals if the load is slightly unbalanced or too heavy. And the heat sinks are paper-thin - pretty much you see in the lowest of the lowest-end PowMax and SunPro.

                                      Probably all 3 you can't see really in the pics but that diode on the 5VSB circuit is very dark around it

                                        I've seen that a few times in Keerda/Logisus PSUs, and it always dries out the two caps.
