We recently received three powerful power supply units from LC Power, and we tried to determine how good they really are. These are three models from the LC Power METATRON series – models with 700, 850 and 1000 W. According to official specs, the company has only one stronger model, delivering 1200 W. All of the measurements were done on the 12 V rail, as it is the most strained one nowadays, and also the most important rail.
We also measured the voltage on the PCI-E slot, as the current graphics cards also have an insatiable appetite as far as power is concerned. After the initial measurements in idle and full mode, we were able to see exactly how big the Vdrop is. It is very hard to “burden” PSUs as tough as these, but changes are certainly noticeable even at half their capacity. The strongest model has definitely got the largest packaging, and it is also slightly longer than its weaker brethren.
All three units are modular, with the 700 and 850 W models supporting the ATX 2.2 V specification, and the kilowatt one supporting the 2.9 V spec. To make the story even more interesting, each model has its own “epic” name: the 700 W being a.k.a. HYPERION, 850 W – ARKANGEL and 1000 W – LEGION X. LC Power didn't state the protections these PSUs possess, but did state the efficiency: 85% for the best model and 80% for the other two.
Before the testing itself, we would also mention the test configuration itself: a Core2Quad Q6600 CPU overclocked at 2.7 GHz with a voltage of 1.45 V (bigger consumption), an XFX i680LT SLI motherboard, an AMD HD 3850 graphics card and 2x1 GB DDR2-833 memory. “Idle” means the general idle Windows state, whereas “full load” was achieved by running MultiCore Prime and the 3DMark GPU test.
