Chill Innovation CP-700M: Quiet EU Power

Power
The brand name suggests cooling, but this Danish company specializes in power supplies, exclusively to the EU market. Some silent PC enthusiasts have said it's very quiet, so we test the 700W modular CP-700M to find out whether it can join the ranks of SPCR-recommended PSUs.

Nexus Value 430 PSU: Affordable Silence

A higher power, more efficient version of a model released back in 2004, the ST45NF has the good looks associated with Silverstone PC cases.

PC Power & Cooling Silencer 610: A legend reviewed

Power
PCP&C has virtually legendary status among IT hardware aficionados and PC geeks, due partly to the brand's engineering-oriented PR/marketing, partly to being the first high end computer PSU, and partly to its high price tags. Today, those price tags no longer seem so high, as competition fills the shelves with mega-buck PSUs from umpteen brands. How fares the Silencer 610 in this new world?

Power
NesteQ is not a name that rolls off the lips of the typical PC user, except perhaps among the uber-geeks. A few silencers might know of it; this is where the German brand is trying to make its mark. A 700W model with unique modular cabling is their flagship model, which we run through our usual electrical/thermal torture chamber... and finish off in our new 11dBA hemi-anechoic chamber.
