Clever Power VGA BoosterBesides the connector types and slightly shorter stature the
VGA Booster isn't very different from the
CPU Stabilizer in its appearance. Below we see the rear 6-pin connectors which will accommodate SLI but not Quad SLI if four individual cards are used. I was able to test Quad SLI since we tested this unit with the Leadtek 7950GX2.
The same concept applies insofar as the
VGA Booster and this is where Clever Power may have some trouble. Ironically there are very few Power Supplies available which provide 18A on the external 6-pin VGA connectors. In fact these are not even mentioned in the EPS12V and ATX12V Guidelines. While the 240VA safety requirement has been met an unexpected side affect revealed how few PSU makers build to the maximum specifications (18A per 6-pin connector). With SLI and Dual SLI systems this would limit one's options even further when choosing a PSU. So how can Clever Power?s
VGA Booster remedy or aid in this respect?
VGA Booster (aluminum cover removed) Taking a closer look at the
VGA Booster in action, the start-up procedure is just about identical to its sibling. Upon powering up your PC the VGA Booster's LED glows red indicating power-up, several seconds later the yellow LED light's transitioning slowly to green where upon a "click" can be heard. The VGA Booster unlike the CPU Stabilizer awaits the Windows splash screen or Desktop at which point 2D/3D loads have taxed the external 6-pin connector drawing current into the unit's capacitor banks.

VGA Booster was tested using an
IWATSU SS-7606 analog oscilloscope. The screen shots below indicate the sine wave as measured directly from the PSU 6-pin connector and then from the
VGA Booster 6-pin connectors.
Once again the results are
prima facie where smoothing is concerned. How the unit works under load and if the unit's current conditioning proficiency can improve VGA performance leads us to our next series of "real world" tests.
