Replace 4 x Chemi-con KZE 16v 1200uF with 4 x Nichicon HZ 16v 1500uF

[Almighty1]

I was looking at some pre-made kits for the ASUS P4C800-E Deluxe motherboard and noticed that the original is 4 x Chemi-con KZE 16v 1200uF but the replacement in the kit is 4 x Nichicon HZ 16v 1500uF, would this cause a problem as the capacitance is increased by 300uF or 25%. badcaps seems to use 16v 1200uF, not sure which cap they are using though.

The esr of the two are slightly different that could affect things, but the small increase in uf should be fine seen as the capacitors are on the less stressed part of the motherboard.

Have the kze's failed, if not why replace them they are good capacitors.

Not sure if they failed or not but it's been 11+ years of 24/7/365, it seems like some of other caps might have failed as system is not working correctly even the built in NIC and the system is really laggy, not to mention the moisture in this house has killed it's shared of things on the system in the last 5 years since I moved here. It's hard enough getting the motherboard out as the full tower case is stuck underneath a table with lots of things on top of the table so if I am going to do it, might as well do it all at once. Those 4 caps are pretty close to the CPU socket though.

The HZs will be fine. It's the CPU VRM high side. The lower ESR may help a little, but it's the VRM low side that really benefits from it.

EDIT: Which kit were you thinking about getting? Don't get cheap eBay ones, as the caps will be fakes.

Suppose you should replace them then, the new caps should be fine

c_hegge, was looking at the one from thecapking.com which I heard was legit and basically all Nichicon HZ's. I wonder what is in the kit sold by badcaps though.

The cap king does sell genuine caps, so he is fine

Going by what's in stock, I would say that they are probably Rubycon ZL on the badcaps.net kit, which are an exact match for NCC KZE in terms of electrical specifications.

I think those KZEs are fine. They endure for much longer than HZ (Ultra-Low ESR caps are only 2,000hr/105c). HZ on the VRM high might give you an overall lower ripple, but KZE will last a lot longer.

Do you have OST on the VRM Low? I bet that's what's causing the lag... I'd also look at the PSU, probably full of defective caps.

Is this the Asus board that took a Pentium M with the special Asus adapter?

So basically Nichicon HZ would actually exceed the specs of the NCC KZE and the Rubycon ZL? I touched the top of the 4 KZE's earlier today when the machine is off and it seems like those caps, not sure of the exact word to use but basically it seems like it's not on as tight as the other caps. I do have OST's and Rubycon YXG's as basically the board consists of the following along with the replacement candidates:
Chemi-Con KZE 16v 1200uF (4,000 hr) x 4 -> Nichicon HZ 16v 1500uF (2,000 hr)
OST RLX 6.3v 1500uF (2,000 hr) x 7 -> Nichicon HZ 6.3v 1500uF (2,000 hr) - seems like while both are Ultra Low ESR, HZ is 1/3rd the ESR of the RLX
Rubycon YXG 6.3v 1000uF (4,000 hr) x 18 -> Nichicon HZ 6.3v 1000uF (2,000 hr)
GSC 16v 100uF x 5 -> Rubycon ZLH 16v 100uF (6,000 hr)

Seems like according to this post: https://www.badcaps.net/forum/showthread.php?t=14131 - it says OST caps will fail without bloating no matter when they were made so this means OST caps can just die without leaking or bulging.

I wonder in real world usage, how long will a 2,000 hr endurance actually last vs 4,000 hr and that's at 105C which is 221F, don't think the capacitors will ever run close to that temperature anyways. I don't think I will be running the same system 11 years later at 24x7x365, only reason for running it still is because of the home renovation in which the entire house will be rebuilt which takes a year so I rather buy a new system after the renovation is done as I won't be here to enjoy it and the other reason is Symantec WinFax Pro only works with Windows XP unless there was another way to keep the old faxes and save to PDF when I need a copy of it from WinFax Pro and use another fax software.

You can see why I want to replace all the caps as it's a pain in the you know where to get the case out from under the table which just has a scanner and printer on top so need something to hold the table up 3+ inches off the floor unless it is a good idea to unmount the motherboard with the case still standing up.

As mentioned in another thread, the PC Power & Cooling Turbo-Cool 450ATX from 2000/2001 that was repaired by PCP&C in 2005/2006 by replacing the Teapo 10v 6800uF, 3 x Hermei 10v 4700uF caps finally completely shut-off and won't power on, on September 10, 2014 except the motherboard status light stays on and also, everytime the AC is plugged in, I can hit the case's ATX Power switch, it will make the lights go on for less than a millisecond. Back in April 2014, there was this weird smell and I thought it was the caps on the motherboard but apparently, it's the PSU. I have already ordered all 27 replacement caps from mouser and digikey for the PSU which should arrive soon and hopefully that will fix the PSU. I have a Corsair CX750m in there right now with Bestbuy's 45 day return policy and it seems to work fine except it lacks the -5v rail which others claim is needed for this motherboard and ofcourse the on-board Intel 1Gbps NIC shows up but Windows XP claims it cannot start the device due to a error code 10 so not sure if it's -5vdc related or not. Tonight, about an hour ago, there was this odor that smelled like a burning match, not sure if it's from the motherboard or the PSU since I have read Corsair CX power supplies do have a weird smell from the caps. I never realize that caps can cause problems like lags and such, wouldn't the board stop working if there were problems with the caps or would that be only if the cap completely blow?

I had to look it up but this is one of the ASUS mobo's that took the Pentium M using a adapter even though I am using a Pentium 4C-3.2Ghz with Hyperthreading, I even replaced the CPU with a spare back in 2010 thinking that was what caused the lag but apparently, that wasn't the case. This is the adapter you're talking about: http://www.xbitlabs.com/articles/cpu...umm-780_7.html
