    Job lot PSU no.2: Antec BasiqPower 550 Plus

    I decided to crack this one open, because the fault i got it with was a broken-off blade from the 120mm fan

    Upon plugging it in, 5Vsb came up just fine. Shorted the green wire to ground, and it powered up apparently fine (if you ignore the racket coming from the unbalanced fan), albeit with a fizzy-squealy sort of noise. OEM'ed by Delta, btw...

    Replaced the fan with another Adda, "grafted" the 2-pin connector onto the replacement.

    Upon inspection, the two Ltec LTG 3300u/6.3v on the 3.3v output were well-bloated. Datasheet for that series can't be found They got either some Rubycon YXG's or some Sanyo in their places... Can't remember right now

    12v: 2x Ltec LTG 2200u/16v -> Panasonic FK 2200u/16v
    5vsb : Taicon PW 1500u/10v & Ltec LTG 1000u/10v -> 2x Sanyo ME-WX 1500u/6.3v
    5v: Taicon PW 1500u/10v & Ltec LZG 3300u/10v -> Rubycon YXG 1500u/6.3v & 3900u/6.3v

    Plus the 220u/35v near the TNY268 got a Panasonic FR 270u/35v in its place, and the Ltec LTG 100u/25v on the daughterboard with the PWM got replaced by a 47u/50v Rubycon YXA.

    Didn't bother with the two small Taicon's on the -12v line :P:

    It's been up&running since yesterday, and powering an AM2 Sempron 2800+ on an Asus M2N-SLI board, with a Radeon 5850 and a 7770 mining for bitcoins, and i haven't had any trouble with it so far

      The TNY268 is a good choice as 5vsb pwm chip, and that booster coil in the APFC circuit looks big enough to do a good job. I have seen much smaller coils which get hot and short. With some good capacitors and a "balanced" fan, looks like a good power supply. Its a keeper.

          Well, the only thing i'm marginally worried about is that the original fan, i suspect, was a "high speed" version (note the "HS" in the model number), and the replacement is a "medium speed" version. The computer case does get quite a bit warm just behind the PSU (where the modular cable connectors are), at full load

              Antec Earthwatts EA-380 smd element type/value
              by sirpsychol
              While recaping Antec Earthwatts EA-380 I've broke one side of unknown smd element, it have no print, it's flatter and darker than smd capacitors on this board, shaped more like resistor but it's not resistor ofc. Unfortunetly the printed description was under it and element was glued to the board so I cant read/tell the letter before element number too. Have anyone any idea what it is? Maybe is there any diagram of this PSU?

              Picking caps for Antec SU-380
              by ajdrenter
              In my search for a proper 5v heavy ATX power supply, I selected an old Antec SU-380 that I've had in storage for a long time. Opening the power supply reveals a couple bulged capacitors. I removed all the caps and made a map for myself. I found the datasheet for the PCE TUR series in this thread:
              https://www.badcaps.net/forum/showthread.php?t=14159
              It says these are general purpose, so I assume I can replace them with any general purpose capacitors, but I don't really know anything about power supply circuits or reading capacitor datasheets. Despite this, I've been shopping for replacements:...

              Antec Smart Power SL300S capacitor replacement.
              by CWEastwood
              Hello,

              I'm currentlly in the process of trying my first power supply repair (really my first soldering project) and have some questions with regard to which capacitors to replace the bad ones.

              The power supply is an Antec Smart Power SL300S ATX12V 300 watt.

              I have successfully desoldered every capacitor from the board without destroying anything (I think) and I am currently in the process of choosing which caps to order. This is where I'd like a little community wisdom.

              Now the capacitors inside are mostly Fuhjyyus (a forum favorite) with 1...

              Antec VP-600P and NE550M dead
              by s_henya
              Hi all,

              Got in these 2 nice PSUs, both died after power surge.
              Both seems to be suffering from the same fault.
              Blown main fuse
              Shorted N mosfet 550v
              VP-600P: 5R280CE short between GDS
              NE550M: MDF18N50 short between GDS

              In terns of board layout these seems pretty identical.

              From past knowledge, once gate get shorted, most likely the for the driver to go bad as well.
              I never tried to salvage blown fuse PSU with shorted Mosfet due to that.

              Is it worth to try and replace the mosfets? is there a chance that the...

              Antec BP500U APFC Coil
              by GnatGoSplat
              Antec BP500U PSU fried in my wife's gaming PC. I smelled something unpleasant last night, so I had a hunch something might be amiss. Woke up this morning to a popped breaker and immediately assumed the APFC cap must have blown. I last fixed it sometime in 2011, there's a thread about it here someplace. APFC and secondary caps that time. Replaced them with Panasonic caps. 10+yrs is probably a good run. It's been running 24/7 the last 3yrs, eth mining with a 1070ti and AFK fishing in Black Desert Online, lol.

              Anyway, cracked it open this morning, expecting it to just be the APFC cap...
