New 400 watt PSU from Zalman
Expected next month (Feb.), Zalman is claiming that this PSU will be "more stable, yet quieter than the previous 300W model". Peak power output is 455W. Can't wait to get my hands on one... especially after reading here that an owner of an Ultra-QuietPC 460 watt unit - my earlier choice - didn't find it very quiet. Definitely a good review candidate...

I wonder what they mean by "more stable"?Herb W. wrote:"more stable, yet quieter than the previous 300W model".
Some Zalman 300 series are "unstable"
Actually, they have problem with EFI circuit or component that causes hi frequency noise. Which they acknoweldged 1/30/03 in Korean and in process of replacing. I don't know how they will deal with it in US market though. (It is on their korean webpage for Korean customers though)
I would logically think they have fixed the problem in 400 series.

It's announced . . . in Korean
The ZM400A-APF appears to have been announced:

So, what of the 300 series? Is this a problem that has been dealt with? I'm thinking that I wanted this PSU until I read your statement.
Specs: Gateway Performance 1300
WinXP Home
P4 1.3GHz fsb 400Mhz (don't overclock, don't feel the need to)
386MB RDRAM PC 800
GeForce2 GTW Ultra 64MB
1 - IBM 40Gb hdd
1 - WD 80Gb hdd 8mb/cache
LTR48246S 48x16x48 CDRW
LG 8160B CDRW
2 NECs
SoundblasterLive! sound card
1 - Vantec Stealth 92mm (back exhaust)
1 - Enermax UC-8FAB 80mm (front intake)
I have no idea the brand/model of the PSU but it's a 250W and I wish it were quiet. No instability issues ever (and Waaaay fewer lockups since getting XP).
Minus the electro-static noise, Zalman PSU is tad quieter than seasonic under load. (on idle, they are same) Currently, I am using Seasonic 350W with fan swap (Vantec stealth rubber grommeted) and I don't think it can get much quieter than this unless
1) 120mm quiet fan blowing with temp/load adaptable circuit.
2) Bigger heat sink with even lower airflow.
3) Water Cooling the PSU!
My bet would be getting Seasonic/Fortron/Verax/True Power and just fan modding it if you are adventurous, or get the Nexus/the silentx if you can.
As for Zalman 300 I would say you get it locally or at place where they won't have problem returning. (PCClub has retail stores) as I am not sure if the stocks available are newer fixed batches or not.
