I have a Dell Dimension E520 and it has 3 blown caps. They seem, from my research, to be from the bad capacitor era, also i had another board with the same caps and all 8 or 9 of them are blown or bloated. So what would be a good brand to get to replace them. Would a 45 Watt desoldering iron, a 25W soldering iron or a 30W soldering iron be good enough to get the old caps off? The dell still works fine, I just want to make sure it wont die in the long run.

Any help would be amazing!

Thanks,
Cam

Go to Digi key, or other capacitor specification sites and look for caps with equal or better spec. ( higher voltage gets some headroom). Write down all info on old caps. Voltage , temp. (usually 105*C) if 85* consider upgrade to 105*. Capacitance and 3 letter code which will tell you what type of capacitor you have. ESR isn't marked on caps. You get this and ripple current from letter code and spec. tables. In Rubycon MBZ, and MCZ were discontinued but MHZ was avail.

I had 4 caps replaced on one of my E520 boards. The ones that went were Nichicon KZJ 2200mf 6.3V. 2 of them next to northbridge, one by memory slot and another by 4 pin power connector. They are NLA. Dell changed vendor for these on rev.A02 they changed vendor to Rubycon MCZ 2200mf 6.3V. I replaced them with Rubycon MHZ 2200mf 10V. caps. These are all low ESR caps. The 10V. are a little taller and have lower ESR and better ripple tolerance than the originals and are newer series. Of course this only applies if these are the caps you're referring to. This is MB# 0WG864. I had a local TV repair shop do this for me. If the soldering iron is not powerful enough you can overheat the board by not removing the caps fast enough. Look in my sig. for what I got my E520 to do. If you'r einterested in Overclocking it I post at OCN as Retrorockit., and made an Overclocking Dell BTX Computer tutorial here.

William P I'm sorry for forgetting the value and with that response I messed up. The caps are 3300uf with 6.3v value. The 2 by the 4 pin and the other one by the heatsink
