1KW PC Power & Cooling SLI power supply has arrived. I purchased it from http://www.pccasegear.com.au/prod2484.htm

Pictures: http://fileshosts.com/psu/PCPowerCooling/1KW/html/

• Fan used is rated at 0.42amps and is quieter than either fans used in 650W Silverstone SLI or 510W PC Power & Cooling SLI psus
• Unfortunately, rails are NOT adjustable externally, but with 1KW psu i doubt you would need to adjust them
• It came with two adaptors, a 24pin to 20pin and a 8pin to 4pin. Also included is 4 psu case screws as well as a 1KW powered by PC Power & Cooling case sticker/badge.
• The box it came in was huge with dimensions of 42cm x 38cm x 23cm
• Apparently each 1KW unit is tested using a Chroma 8000 ATE machine. You can see the report at http://www.pcpowercooling.com/pdf/TC1KW_report.pdf

Highlights:

* 1KW Continuous (1.1KW Peak) @ 50°C
* Fits Std. ATX Cases (20” min. depth)
* +12VDC Rails Total 66A (70A Peak)
* High Efficiency with .99 Power Factor
* Ultra-Tight Regulation (+VDC @ 1%)
* Amazingly Quiet Cooling System
* Complete Array of Output Connectors
* EPS12V, SLI, and SSI Compatibility
* 5-Year Warranty; Unbeatable Support

Specs:
Typo guess continuous = 1000W



Dimensions and connectors:
Only down side is only 1xfdd connector, if you use DFI NF4 and SLI and need to use the fdd power connector, then you'd need an adaptor for powering a floppy drive if you have one (which i still use a floppy drive).



Test 1 - standalone psu
With 92x38mm sunon 120cfm (13W) + 80x25mm sunon 50cfm (4.3W) fan attached, digital multimeter read rails as



3.3+ = 3.397v
5+ = 5.09v
12+ = 12.24v

Test 2 - in below system

Opteron 148 CABYE 0543FPMW @2200mhz stock
Corsair Hydrocool 200EX
512mb HIS X1800XT
4x 80GB Hitachi 7K80 SATA II raid 0
1x 250GB Maxtor Maxline Plus2 PATA
LiteOn 165H DVD-ROM
FDD



Digital multimeter read the rails as

IDLE:
3.3+ = 3.364v
5+ = 5.06v
12+ = 12.19v

LOAD: CPU Burn K7 ran for 10mins



Forgot to measure the rails with multimeter so will redo the test

Okay retested under load but @3014mhz at 1.536v

Digital multimeter read

3.3+ = 3.353v
5+ = 5.05v
12+ = 12.19v

Windows showed

Stressprime


CPU Burn K7


Conclusion:
- Well 12+ rail is rock solid and didn't budge according to MBM5 or digital multimeter readings.
- 5+ rail dropped (0.6%) from 4.97v to 4.94v under load in MBM5 and 0.01v drop (0.198%) according to multimeter from 5.06v to 5.05v.
- 3+ rail dropped (0.615%) from 3.25v to 3.23v in MBM5 and dropped (0.327%) from 3.364v to 3.353v from multimeter readings.
- If you take into a/c all 3 rails that's ~0.405% fluctuation on average of 3.3+, 5+ and 12+ rails according to MBM5 or average fluctuation of ~0.175% according to digital multimeter read out. That is within the rated specs of 1% ultra-tight regulation claimed by PC Power & Cooling if you take MBM5 or the multimeter readings
- Real test will be when i use phase change, dual core cpu oc'd and SLI or CF video cards oc'd


Update: Feb 11, 2006


Also got a reply from PCP&C folks regarding distribution of the 3x 12+ rails:

Guess that explains why cpu stress loading has rock steady 12+ rails as they're from +12V1/V2 while X1800XT under load is shared off +12V3's 36amp rated rail.

Good luck eva, I'm sure you'll put it to good use

Can you further explain this statement:

"Unfortunately, rails are adjustable externally, but with 1KW psu i doubt you would need to adjust them."

I would have thought adjustable rails are

i knew you'd be the first.

Nice, be interested in your results.

eva2000

Updated first post with load results... very steady rails with 12+ rock solid

alpha0ne

Very good to see such tight regulation under load and slightly better than spec

Looks like your pretty much set re PSU for at least another year

Wannna sell one of your 650

dinos22

ok man don't pussy foot around with this PSU

plug everything into it.....i mean every single hard drive you can find.......all the cards, media drives, fans, air con unit......freaking lawn mower and see what happens

bet ya the rails won't budge

eva2000

I have 6x 120x38mm delta 190cfm fans rated at 3amps each or 36W and 4x 92x38mm sunon 120cfm fans rated at 13W each

268W or 22amps of 12v power draw hehe

should I ?

Yeah will be selling my 650W Silverstone SLI PSUs soon (adjustable 12v rail on these)
