PRODUCT PICTORIAL AND WALKTHROUGH (cont'd)
Finally, the two PCI Express cables each carry two 6-pin connectors, providing the user with the ability to run quad-SLI should they have the desire (and money) to do so. I'm assuming that you don't need to see the power cord and screws. They seem to be high quality, as these things go. Let's get on to the testing phase and see how Xclio's 850W PSU performs.
PRODUCT INSTALLATION AND TESTING
Let me preface this section by saying that I don't have the kind of sophisticated (and expensive) electronic test equipment needed to fully and selectively load a power supply nor is it really required. For this review, I've chosen a DFI LanParty SLI-DR motherboard because it's notoriously finicky about the power fed to it.
The testbed used for evaluating the Stablepower 850W consisted of the following.
AMD Opteron 148 processor @ 2.7 GHz
DFI Lanparty UT nF4 SLI-DR motherboard
eVGA 7900 GS KO
OCZ 5002048ELGE-K (1024mb X 2) memory
Xclio Stablepower 460W PSU (model XS6000783)
Western Digital WD800 SATA hard drive
LG CDRW/DVD Combo drive
Testing consisted of monitoring voltages from the +3.3V, +5V, and +12V rails while running multiple passes of Prime95 and playing a few rounds of UT2004. Voltages were monitored with a digital multimeter. I was very impressed with the results, in light of the high demand of the components and the power-sensitive motherboard. Over several days of testing, including overclocks approaching 25%, rails were very stable and not one power issue reared its ugly head. Random checks with the multimeter throughout the testing period yielded the following results:
Even more impressive than its stability, was its silence. I can honestly say that the Stablepower 850W was silent throughout testing. The fan turned so slowly it was almost possible to read the hub label during operation! The cables were generous enough to reach all the installed devices in the full-tower NZXT case used in the review.
Oh, yeah. I almost forgot that mystery LED. Well, with the PSU turned on, the LED glows red. Power up the system, and it turns green. Now you know as much about this feature as I do. If it's a troubleshooting aid, as I suspect, Xclio should mention it somewhere. Just a thought.
