I just have two options.
There in Costa Rica when you ask for a Quality PSU they look like that :confused2:
And says things like "Eeeeehhhhh whe just have this" and show you a 350W PSU of a brand totaly unknown.

First:

http://www.crazybuy.com/mcps-ny/product.nsf/0/f1570975fd2b8ca888256e060079ba2c?OpenDocument

Second:

The win350-pn not the win300-pn
http://www.hipomedia.co.yu/napjanja.htm

Which one to chose???


This is the best i found.

Hey, i've got a little question about that +12V

I'm searchin to buy an Enermax Power Supply 420W Active PFC Monitored Fan SATA Noisetaker Serie [EG425AX-VE_G_SFMA]

From their site i see that that one has a +12V1 15a and +12V2 14a

What do i make of this? +12V is 29a or arent u supposed to add those 2 together?

+ does it need a different connection? I only know about the square one near the agp slot and the big one near psu itself


Tnx for ur help

I did not see any Enermax or Antec PSU @ Tigerdirect, they did sell them at one
time, I know for a fact that www.newegg.com has them in stock, and newegg is
a secure place that you can buy via the web, they have a very high customer rating!

I would only buy a Enermax, Antec, Fortron or PC Power & Cooling PSU!

Take care, :biggthumbsup:

If I were you, I would buy the PSU that we all have been talking about
in this forum, Enermax, Antec, Fortron, or PC Power & Cooling!

Thermaltake 480 = 515 watts @ 100% - 515 watts @ 70% = 360 watts

PowMax 500 = 542 watts @100% - 542 watts @ 70% = 379.68 watts

Vantec 470 = 656.8 watts @ 100% - 656.8 watts @ 70% = 459.76 watts

Antec 480 = 553 watts @ 100% - 553 watts @ 70% = 387.1 watts

The Vantec PSUs overall watts @ 100% are the highest and again @
70%, but you also need to look @ the 3.3v + 5v combined watts!

The Vantec PSUs overall figures check out nicely, but I am unfamiliar
with this brand! I would really like to know what PSU manufacturer is
making these for Vantec ! I bet it?s a Fortron PSU with a sticker that
says Vantec, I will have to go and check out one of these PSU!

xsoft, if these are your only choices that you can purchase from Guatemala,
then I would still go with the Antec 480, because of their reputation, and
then the Vantec 470 would be my second pick, just because of the overall
watts, but it might be risky, who knows!

Take care, :biggthumbsup:

I have been using (for the last 6 weeks) a PSU from a company I had never heard of before Jou Jye Electronics.
Previously I had a QTEC 500W but that 550W was based on "peak" and not "max" amps - in other words the 550 watts were what I would call "marketing watts".
I , therefore, removed the QTEC pretty swiftly.

The specs of the Jou Jye 550 seem reasonable.
I found one thread about it here :
http://www.computing.net/hardware/wwwboard/forum/25123.html

Anyone else heard of them before ?

No Chris, have not heard of JJE products...but if it works to your approval...keep all informed of it's performance. Could be a new product just breaking in to the market.
