“Pure” and stable powering of all the system components is a fundamental requirement to keeping your computer up and running at its nominal frequencies and, moreover, during overclocking. That’s why, for example, a good power-supply unit means no less for an overclocker than an efficient air cooler or a water-cooling system. I guess you can name the hungriest components of a modern computer yourself. They are the central processor and the graphics card, of course. Obtaining a premium PSU, you can stop bothering about the stability of the power these two devices feed on, but an insufficient “purity” can cause problems, theoretically speaking.

The topic of this review comes from OCZ Technology. I will be talking about special wires that efficiently (so says the manufacturer) suppress electromagnetic interference in power circuitry of modern graphics cards, hard disk drives and other PSU-powered components of your computer. The description of the innovation, taken from the manufacturer’s website, read as follows:

The OCZ Enhanced VGA and HDD Power Lead allows users to eliminate “Snowing” and “Water Wave” effects when plugging into high-end VGA cards and Hard Disk Drives. The OCZ PowerShield EMI Control technology with copper-shielded power leads provides extreme current stabilization and is ideal solution for high-resolution applications such as PC games, video editing, and 3-D graphics design. In addition, OCZ’s PowerShield EMI Control technology substantially reduces inbound and feedback RF interference.

Well, it was years ago with a RADEON 7200 from some obscure manufacturer that I last saw such “snowing and waving” on the screen on my monitor, so I just can’t judge if the “wondrous wires” are of any use in this respect. Anyway, I am going to check out OCZ’s claims at least partially, and assess the efficiency of the Power Lead with an oscilloscope.
