Introduction
Most of you know that OCZ acquired PC Power & Cooling back in May of this year (2007). I am not sure of the details of this little merger but I know great things can come of this. OCZ has had some good performing PSU units and some have even reached approval of die hard overclocking enthusiasts. I am not here to talk about OCZ’s past but the future of PCP&C. PCP&C is known for their incredibly stable power supply units. The founder of PCP&C (Doug Dodson) has strict beliefs on how a PSU should be built and stakes his reputation on it. A belief OCZ believes in as well, enough to have Dodson become the new CTO (Chief Technology Officer) of OCZ.
Even though Dodson is no longer the owner of PCP&C, he still is in charge of the production under the PCP&C name. This is a good thing because the more I tear into these units the more impressed I am with the designs, performance, and stability each one has. By no means am I an overclocking enthusiast that pushes my equipment far beyond the limits, but I do like to rely on a stable system to keep tweaking from time to time.
As the demands for power increase so do the recommended equipment and once again PCP&C is there for another certification. With the recent release of ATI’s power hungry 2900 XT, power draw is at an all time high for even one GPU unit. With a reported 215 watts per card that leaves you needing the recommended 550 watt PSU for a single card and a 750 watt PSU for Crossfire. With the Silencer 750 making the certification, PCP&C wanted to release a special unit just for the occasion. The Silencer 750 Quad Crossfire Edition (CF) sports a red paint job in celebration of ATI’s theme. Now lets see what's new with the Silencer 750 Quad-CF.
