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.

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.

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.

Please explain why, I live to learn

Is it due to the active PFC or something? I mean I've seen Primary caps in L&C powersupplies with almost twice the farad rating!!!

Re: Power supply build quality pictorial DISCUSSION

Well, i was going to post pics of my Delta DPS 300BB, but it looks like larrymoencurly already has.. I bought a pair of them back when directron.com had them for $13 each.. I wish i would have bought at least 6 more of them..

They are perfect for running AMD socket A systems that are demanding of +5V and +3.3V. I've got one in my HTPC as a matter of fact, although it would probably work fine with a 250W PSU, i want that little HTPC to live a long and happy life, so it gets a server grade 300W Delta.

It's probably the best built PSU i've seen, when it comes to heatsinks, tons of toroids, and good quality capacitors. If only the 300BB had a +12V P4 connector, it would be powering my Athlon 64 also..

On the label, it says that you can have 245W max between the +3.3 and +5. I wish Delta would sell their stuff to end users. I'd love a 400W PCIexpress compliant one..

Do you mean you haven't added the connector to it? There's an unused hole in the circuit board for the pair of +12V wires, but for the ground wires I had to drill a hole really close to a capacitor. Sure, this PSU is rated for only 13.5A @ +12V, but they're honest amps.

Re: Power supply build quality pictorial DISCUSSION

I have a question. There are always very low capacitance (2.2 to 10uf), medium volted (25-50v) caps on PSUs. Some are found beside transformers, some near coils, etc. Should these caps remain during recapping, as some are hard to reach?

Re: Power supply build quality pictorial DISCUSSION

These very little caps should be left alone since 470uf or 1000uf or more caps are affected. The very little caps aren't affected.

Re: Power supply build quality pictorial DISCUSSION

A bad Jamicon 1uF cap in my TV caused the picture to stretch at the bottom part. And several years ago, my then-fairly new cheapo PSU, maybe a Deer, a 1uF, 16V cap shorted, and after replacing it I borrowed my friend's scope and saw 50V spikes across it and a few other 16V caps.

Re: Power supply build quality pictorial DISCUSSION

You can leave most of the small caps alone, barring a few related to the ATX auxiliary supply, which generates +5VSB. There's a primary side flyback cap there that fails often - check the thread on Eurocase PSUs for more details.

This PSU has not been used yet, so unsure of its reliability. I'd guess it's not too bad. Comes with a PCI plate or 5 1/4" drive bay filler for a fan speed knob, i think.

I think that was made by High Power, their HPC-480-102DF power supply has the same dual orange 80MM fans, black casing, and even the same amp ratings.

if it were run any at all all the caps would have likely failed.

That Powmax redundant power supply has been known to give out a small puff of smoke, but work okay after the first turn-on.

Where did you get that 4.35V reading on the +5V rail?

Did you use the motherboard voltage monitoring or did you use something that has more accurate readings?

Pictures of the FSP235-60GT are found on https://www.badcaps.net/forum/showth...ht=fsp235-60gt

Mine was built in 1998, and had smaller heatsinks than the ones in the link. It also had some "WC" brand capcitors, as seen on https://www.badcaps.net/forum/showth...3126#post13126

The first filtering capacitors for the +5V and +3.3V rails were Fuhjyyu TMR Series (3300uF 10V), with the output capacitors being Fuhjyyu TNR Series (4700uF 10V TNR for +3.3V; 3300uF 10V TNR for +5V). There was one "WC" branded capacitor (1000uF 16V) on the +12V rail - a bit inadequate.

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.

Should I be worried about this PSU found inside my external drive enclosure?

https://www.badcaps.net/forum/showth...3626#post13626

It's not UL approved, and there's no room to add a line filter because the circuit board normally sits right next to the AC receptacle. Also the plastic sleeving of the black/gold cap at the far right was melted in a few places, and its leads had a big solder bridge between them -- on the top side of the PC board.

OTOH the USB-IDE controller is based on an NEC chip

Re: Power supply build quality pictorial DISCUSSION

That power supply looks like junk to me - the manufacturer had cut quite a few corners in it. There is also a Fcon capacitor in it as well. If there are no specifications on the supply, I recommend a good supply with 2A output each on 5V and 12V.
