1KW PC Power & Cooling SLI power supply tests

[eva2000]

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

• 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 :heh:

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
