[KLUG Hardware] Leadman (POWMAX) LP-6100E 500W PS ...

[Bryan J. Smith]

Hmmm, the reseller and manufacturer seem to have conflicting
information.  The reseller is Computer Geeks and they are usually
_very_good_ about reading the specs off the box.  Maybe Computer Geeks
is quoting the "max" ratings and Leadman's site just quotes the
"nominal" ratings?

http://www.asound.net/Asound%20Web/Power%20Supplies/powmax%20power%20supply%206100e.htm 
LP6100E (CompGeeks):  +3.3 = 30A, +5 = 50A, +12 = 25A
 LP6100E  (Leadman):  +3.3 = 30A, +5 = 40A, +12 = 16A  (3.3+5 = 250W)

Leadman does report 250W on the +3.3+5V.  That's a bit high for its
ratings considering Antec and Enermax 400-431W products:

http://www.antec-inc.com/product/powers/p412x_spe.htm
http://www.enermax.com.tw/products/switch-main.htm

     PP412X (Antec):  +3.3 = 28A, +5 = 40A, +12 = 18A  (3.3+5 = 245W)
EG465P-VE (Enermax):  +3.3 = 38A, +5 = 44A, +12 = 20A  (3.3+5 = 220W)

It's hard to tell what the vendor specs really tell.  I mean, the
Enermax offers more current on both the 3.3 and 5 lines than the Antec,
but it rates its 3.3+5 combinational as lower.  But my _personal_
experience with both resulted in the PP412X being _barely_ able to drive
my fully loaded dual-Athlon (lots of waste heat as voltage drops
occurred due to insufficient current, CPU fan "throttling," instability
in general) whereas the Enermax is what I'm using now (not nearly as
much heat from that PS, no CPU fan "throttling" anymore, very stable).

Time to hit the next to see if anyone has done a review of this Leadmax
product.  I know the Antec and Enermax are good buys, but they don't
hold a candle to PC&Power Cooling's products once the system "warms up"
(and the former incur some current loss due to heat, although not as bad
as most).
