Hello all. I'm planning to build a SLI gaming rig using the K8N Neo4
Platinum/SLI motherboard, AMD athlon 64 3200 cpu, (2) western digital raptor
74 gigabyte 10.000 rpm SATA HDD, (1) 40 gigabyte Seagate EIDE UDMA 1007200
rpm backup HDD, gigabyte of PC3200 DDR 400mghz dual channel memory, 2
optical drives, a floppy drive and a NVIDIA Geforce 6600 GT PCIe video card
(I hav"nt decided what brand yet.) and I'm concerned about what PSU (power
supply
Unit) to use. Instead of paying $175 for something like the Silverstone
ST65ZF 650W or the Enermax EG701AX Noisetaker 600W Nvidia certified PSU. I
found the Enermax EG565P-VE FMA 535W SLI PSU for $89 on ebay which is not
certified by Nvidia but is configured for SLI . Here are the specs.


Specifications:
a.. Model: EG565P-VE FMA 2.0
b.. Maximum Power: 535W (support both 24pins and 20pins motherboards)
c.. Voltage Rails:
a.. +12V: 34A
a.. +12V1: 18A
b.. +12V2: 18A
b.. -12V: 0.8A
c.. +5V: 32A
d.. +5VSB: 2.5A
e.. +3.3V: 32A
d.. Input Voltage: 90V~135V or 90V~265V
e.. Input Frequency Range: 47Hz~63Hz
f.. Input Current: 40A/115V and 80A/230V max. during cold start
g.. Hold-up time: 17ms at 115VAC or 230VAC, full load
h.. Over Voltage Protection: +5V: 5.5V~7.0V; +3.3V:3.76V~4.3V; +12V &
+12V2: 13.4V~15.6V
i.. Over Load Protection: 110~160% of max load
j.. Over current Protection: +3.3V: 55A (max); +5V: 48A (max); +12V1 &
+12V2: 20A (max)
k.. Over Temperature Protection: Operating Ambient 10ºC~40ºC, Storage
Ambient -40ºC~70ºC
l.. Humidity:
a.. Operating: to 85% relative humidity, non condensing at 25ºC
b.. Storage: to 95% relative humidity, non-condensing at 50ºC
m.. MTBF: Greater than 100K hours at 70% of full rated load; 230VAC / 50Hz
input; 25ºC ambient
n.. EMC: EN55022 Class B, EN61000-4-2 Class B, EN61000-4-3 Class A,
EN61000-4-4 Class B, EN61000-4-5 Class B, EN61000-4-6 Class A, EN61000-4-8
Class A, EN61000-4-11 Class B, FCC Part 15 & Part 2, CNS 13438 Class B
o.. Safety: Approval UL, cUL, TÜV, CB
p.. Dimension: W150 x H86 x D140 (mm)
Connections:
a.. 1 x 20/24-pin Mainboard
b.. 1 x 4-pin P4
c.. 2 x 6-pin PCI Express
d.. 4 x SATA
e.. 7 x 4-pin Molex
f.. 2 x 4-pin FDD
g.. 1 x Fan Monitor
and I'm thinkin why should I pay $100 for a Nvidia certified psu when the
one for $89 will work just as well. I need your imputs on this and anyone
who is using this psu, what do you think of it ?. problems etc. Also I need
to know if the 20/24-pin mainboard connection from the psu is conpatable
with the K8N Neo4 Platinum.. Your prompt replies will be appreciated.

Thanks

I have a K8N board, the PSU I use is a 550w Antec, it works fine and
runs all it's hardware, mainly a game only rig it has never shown any
power faults, actually any faults.

While mine runs a soc 939-3500 64 bit cpu, 1g Corsair XMS memory, 2 X
80g SATA drives in a claytons raid, and a 6600 Albatron / ATI card
chosen due to it's "3 year warranty", Creative 2ZS Platinum sound
card fills the box with the main bits, while not top end it does me
good service, all works fine and no game yet put in it has showed
any faults or quality degredation at high video game settings.

Buying cheap PSU's means trouble, buying generic or new named PSU's
from Ebay means your system may not even boot, an Antec 550 is only
$148 AUD here, that's cheap and all now come with SATA connections
either in with the board, drives or on the PSU, and the square 12v
connector for the duals + the Intel socket, kept seperate from the
other systems mentioned here, spend the cash on memory or vid cards.

Yes most are ex folders being so many, long since converted for other
things, I was in the top 100 for folding #66 from memory before I
stopped it, 17 boxes running 24/7 pull a LOT of power, nearly a
grand in just 3 months just too much.

Anyway, I use either Antec or Enermax, the Antec seems to be more
stable with more exact voltage rails, the Antec is also cheaper, my
current 12 other smaller systems range from an old 2400 T/bred to
Bartons of 2600 - 2800 - 3000 - and 3200 and depending on what
hardware is installed 430 450 and 480 Antec and 430 Enermax PSU's.
