RE: : RE: *Power Consumption* Core i3-530 32nm + GA-H55M-UD2H

Jack,

On the S2L board, it hasn't worked consistently for me to apply ATX PWR_OK before pressing the power button. This was also discussed in this thread and sub-thread:

http://www.audioasylum.com/cgi/t.mpl?f=pcaudio&m=65451

But it may be a difference across different boards.


I can play with this a bit, tho. I have the 5vSB & -12v on one switch and the PWR_OK on a second switch, so I can vary the sequencing.

In any case, I am pretty pumped and excited about getting this working consistently. It has been a tease, powering on the test board sometimes, but not every time.

BTW, this is all with no relays or PicoPSU. I when I plug the beast in, it directly energizes the 3.3v, 5v, and 12v rails. The -12v and 5v control voltages are turned on and off by switches.

I'm happy that this is working with such a simple setup.

Also, very happy to hear your comments on the sound of different batteries. I personally wouldn't use NiMH or NiCD unless I had to... too much self-discharge when not being used. I have LiPo packs in various capacities and every cell-count combo from 2-5 cells and all are pretty high-current for their capacity (some packs I have list peak draws of over 100 amps... I use these on larger electric helicopters).

I'll report on sound with this supply after I have a chance to listen a bit. I also have plans to do some listening to various regulators and various power sources for the P24... I am skeptical of the current recommendation to go with a 2nd computer power supply for that, I found a significant improvement in SQ when I went to linear supplies for my 'dirty' connections... 12v screen, 5v USB, and 5v HDD. This surprised me, but even more surprising was that the quality of the caps I used around those regulators also made a difference... so I expect a good linear to be better than an SMPS for the P4 also.

Again, thanks!
