I'm surprised they didn't use 12K caps which they use on their WS series of boards. Not a big deal though.

As long as the capacitor itself is high quality (which obviously is the case with FPCAPs) anything above 2000 hours @ 105°C rating is essentially excessive, unless we're talking about hi-rel solutions such as medical, aerospace or space type of applications. The 10k rated caps will have a projected life time of ~178k hours at sustained 80°C.

what's the max ppm you need to be able to claim that rating? having that rating with high bad part ppm is not going to fly

Temperature coefficients are not specified in the public, model specific datasheets for FPCAPs.

Here is a generic chart: http://www.nichicon.co.jp/english/products/pdf/2012fpcap_catalog_05.pdf

p8 has estimated life for operating temp. I guess we'll just have to trust them keeping ppm to a very lo level. otherwise poping/burning a couple caps after a couple years of use can be dangerous depending on where they are used

is there another thread to check for ASUS board rumours? I'm interested at X399, but I don't see any ASUS board with proper 8 SATA. wonder if they are going to have one with 8 SATA. that U.2 seems useless as those will likely not be used for a long long time or never to be used just by looking at the U.2 product on the market

Motherboard availability is like impossible lol. They got 1950Xs at Microcenter, 4 in stock, but no mobos of course, and I called them, their shipment date of X399 mobos is Wed and Fri, basically.

I just rather get the CPU now before that goes out of stock and wait for my preferred mobo, Gigabyte.

The only option available is MSI Carbon from Amazon, that will arrive Aug 22 from Amazon. I have NO experience with MSI motherboard, i am familiar with Gigabyte.

Edit: actually, that MSI Carbon looks impressive, the big heatsink looks nice. what about the VRM on it?

Giving this another week for mobo availability to be better for X399 from any sources.

I look away from all three ASUS X399 boards just because of this gimped number of SATA ports. I'm also not sure why they put a U.2 connector there to waste the space when one of the M.2 already has to hide under the heat sink. as far as I know, you can count the number of U.2 devices available with your fingers and I have yet to see Intel promoting U.2 devices with effort

if you go to Amazon's page for 1950X, you can see bundle deals with mobo or aio. not sure if it can compete with ucenter though

Do anyone of you fine gentlemen know if the Noctua NH-U14S TR4 will be compatible with the MSI X399 Carbon VRM heatsink in a traditional horizontal airflow orientation?



It has a width of 150mm.

http://noctua.at/en/home-product/nh-u14s-tr4-sp3/specification

If it won't fit, I will go with the NH-U12S TR4 since it has only 125mm width, but I would prefer the larger U14S.

Very thankful for any replies, since I'm eager to place an order.
