    Dell XPS 410, KZG 6.3v Caps

    Recently my computer stopped powering up, and after the typical trouble shooting I've come to the conclusion (by visually inspecting) that its 3 bad caps. I read it's ok to replace them with ones rated higher, but from experience can anyone offer some suggestions on brand any maybe places to purchase them? I wanted to just replace the 3 busted ones without buying a whole kit. The original capacitors are KZG 6.3v 3300uf. I am willing to pay more for caps, I just cant seem to find a tested and proven high quality replacement. Would radio shack have decent replacements (to avoid waiting for shipping) ? Thanks in advance, and if this has been asked before I am sorry.

      Thanks, would it be logical to switch to polys for this repair? The 2 side by side are busted next to the aux power on the mobo, and the 3rd is to the right of the cpu. Sorry for lack of pic, I left the mobo mounted until I get some caps in. If polys wouldn't be ideal I'll go ahead and order those.

        KZG series is known to be unreliable. I would replace them with a reliable brand of capacitors. Switching to polymer can be done, but isn't really necessary, and may even be ill-advised depending on the locations of the capacitors.

        I would replace all the KZG capacitors, even those that show no signs of failure. They likely aren't far behind, and sometimes KZG can fail internally without showing any external signs.

          You should replace all KZG even if they aren't bloated because:
          - If some are gone the rest aren't far behind.
          - KZG have a habit of failing without bloating at all.

          Upgrading the VRM to poly is pretty safe.
          -
          Any other caps need to be analyzed cap by cap.
          ... and you can't [safely] change uF much on many so there may be some that can't [safely] be changed.
          - To do it right:
          Need to trace out the circuits and find out what each cap does.
          Need to check the actual voltage on each cap.

            Thanks for the advice..now just waiting for new caps to show up in mail. Quick question though.. Should I check my psu or get a new one? I read Dell went the cheap route on most components. If I do check it I was told they can hold tons of power for weeks, is there a was to discharge it? Thanks in advance.

              They don't hold tons of power for weeks at all. by the time you undo all the screws on the case and PSU, it will be totally drained.

                ~~~ Unless the discharge path is broken. That's pretty rare though.

                  The Dell XPS-410 power supplies are 375w. They will handle a fully loaded machine at the max config allowable at time of purchase back in 2007.

                  Max config:
                  Intel Core2 QUAD q6600
                  4 gb RAM (all slots filled)
                  nVidia 8800 gtx
                  (2) 7200rpm HDD

                  but at that config, when the machine was stressed to max (like 3D gaming ... Crysis maybe) the PS is running at around 85%. Easy for a nice new high quality PS, but not so easy for a 4 year old PS.

                  When I upgraded my two 410's (with q6600) to also hold a ATI 5770, I also installed a Corsair 650w ps. Now, even at max, the PS only runs around 40-50%.

                  What is inside yours and do you plan to do any more upgrades?

                    Re: Dell XPS 410, KZG 6.3v Caps

                    I am trying to repair a Dell XPS 410 MB and already replaced six 6.3V 2200uf caps but when we tried the board out, we got the same flashing amber power light. I now want to replace (3) 16V 680uf, (3) 16V 470uf, and (1) 6.3V 220uf caps. Does anyone have a recommended list of replacements or is the newbie reply go look at the store?

                        I had three sick XPS 410's with bulging caps on the motherboards. All three have been repaired with cap replacements. They each had a total of 3 680uf 16v KZL capacitors. Only one capacitor of this type was bulged at the top. I wanted to know the specs of this capacitor but could find absolutely no mention of a KZL series capacitor on the net. In fact Google underlines KZL in red and advises did you mean KZE. Of the three of these on each mb, one resides right next to the cpu power connector.
                        The only mention I did find on a forum was a photo post where a question was asked about a KZL cap on a mb. The responder said that it looked like a KZJ and the original poster replied that he read it wrong and it was KZJ with what had looked to him like a backwards L. The caps I have do not have backward L's.
                        A mysterious cap indeed. Does anyone know the specs of this cap or what should replace this KZL. Thank you for every response.

                            Those 16V 680uF caps are probably general filters on the motherboard and don't really need to be anything special. But just to be safe, use Nichicon HM, HN, or HZ. Although I bet even something equivalent to Rubycon ZL will work fine. The badcaps.net store should have all of these brands and series.

                              Thank you Momaka for the information. I have decided to do just exactly that, pick a decent low esr and high ripple motherboard type capacitor as you mentioned and call it good. Still find it odd that the caps in question seem to have no history whatsoever and that I can find data sheets on any other cap that I have ever encountered. Next up, monitors. Happy Holidays

                                FWIW the actual max. spec for these is much higher than what Dell offered at the time. Due to being able to power a Pentium D these have the ability to run a 135W, QX6800 2.93GHz CPU. Larger RAM modules came along and with a BIOS update can run 8GB DDR2-800.
                                Overclocking is possible using Throttlestop 6.0 software to control Voltage and multipler in Windows.
