The PSU was fitted into our test rig and went in pretty smoothly; the cables used were long enough to hide round the edges of components/the case, and the cables not in use were able to be hidden away fairly easily (granted they would have been more of a pain to hide in a top PSU mounting case).
The test system was as follows:
Supplied by Abit
Intel C2D E6600 @ 3Ghz
ATI HD4850 512MB
Supplied by Sapphire
Supplied by Noctua
Crucial Ballistix 2GB PC2-6400 800Mhz
Non removable disks
WD 7200rpm 250GB
Cooler Master Cosmos S
Supplied by Cooler Master
To load the PSU as much as possible the following applications were run simultaneously to stress each subsystem of the PC:
- ORTHOS StressPrime - to max out the CPU and tax the memory
- Virus Check, Spyware Scan – To tax the hard drive
- Importing a CD to iTunes – To load both the CD drive and the HD
- Playing Back the imported CD from the hard drive
- ATI-Tool’s 3D View – To stress the graphics card
Reading from the voltage rails were then taken from the PSU directly with a digital multimeter (DMM).
In trying to work out how the 6 12v rails were split across the connectors so that I could read them separately with the DMM, I noticed that there are different coloured stripes on the yellow 12v wires. There are: Yellow&Red, Yellow&Blue, Yellow&Green, Yellow&White, Yellow&Black and all Yellow.
So I presume that the rails are split into these different colours, which are assorted as follows:
Black and Yellow
24pin ATX connector P1
4/8pin ATX/EPS connector P3, P5 (two 8pin EPS that split to two 4pin ATX)
P2, P4 (Half of each 8pin EPS, redundant when above is split into 4pin ATX)
Blue and Yellow:
PCIe connectors P6 (8pin), P7 (6pin), P8 (6pin)
Green and Yellow:
PCIe connectors P9 (8pin), P10 (6pin), P11 (6pin)
Red and Yellow:
PCIe connectors P12 (8pin), P13 (6pin), P14 (6pin)
White and Yellow:
SATA Connectors P15 – P23
Molex Connectors P24 – P28
Floppy Connector P29
The voltage regulation on the Cooler Master 1100W UCP PSU is really great, ATX spec allows for voltages rails to be within 5% of the target voltage, most enthusiast PSUs are tuned to within 3%, but this 1100W UCP PSU is well under 1% tolerance on every rail.
With as much load as our test system could supply the UCP 1100W didn’t even break a sweat. The most any rails moved was 0.17%, which is great performance.
