    LiteON PS-6401 400W OEM PSU - Bad caps!!?

    Hello again, long time no troll

    I picked up this LiteON 400W OEM PSU from a PC recycling shop for not much (I don't remember how much exactly, but it wasn't very much), took it home and tested it with an old Skt370 junk M/B I had lying around. It turned on fine but the fan sounded a bit noisy, so I was going to open the unit up to oil the bearings. And when I popped the case open, I discovered a blown 16v 1200uf TAICON HD on the secondary circuit.

    GRRRRRR!

    Anyway, I looked up the Taicon HD, it is equivalent to Chemi-Con's KZE and (somewhat) to Sanyo's ME-WX. However, I don't have any of those caps, but I do have access to some Rubycon MBZ 1200uf 16v, which seem to have better ESR (50% lower it seems) and comparable ripple current, but they're only rated at 2000 hrs @ 105c, whereas the HD are 5000hrs @ 105c.

    So the answer is, would it be possible for me to use these MBZ as long as I keep the PSU really cool? (I do plan on powering a Prescott P4 with this PSU.)

    Thanks for any help,

    Aaron

    I'll probably be the only person going to SteamOS once it gets out of beta (ha ha.)

    If the Ruby MBZ isn't adequate to replace the busted Taicon HD, would the Sanyo WG do?

      sure.
      mbz will be overkill in a psu.
      but it cant hurt to use them.

        For the 12v rail, I would go with a slightly larger value, non-aqueous cap. The Chemi-con LXZ 1500/16v/10mm is a reliable and inexpensive replacement. If you can fit 12.5mm caps, a wide variety of Nichicon PJ/PL/PM/PW etc. are possible, as well as Chemicon LXF, which was the endurance champ for many years with a 15k hour endurance.

        BTW, those green-sleeved Taicon HD 1200/16 usually fail when hot and under high ripple current - check your airflow as well, substitute a ball-bearing fan and disable the fan speed control if you can.
