The BeQuiet! Straight Power E9 700W is a very good choice for an everyday high grade enthusiast system. What makes this power supply very appealing right now are price drops in the United Kingdom, specifically ARIA who are selling the E9-700W for £96.74 inc vat, a drop from full retail price of £134.99 a short while ago.

We love the appearance and build quality of the BeQuiet! power supplies, the two tone colour scheme with orange strip really looks beautiful and the quality of finish is second to none. The paint work is both deep and resilient to rough handling over time. Sadly this unit isn't modular which means that an enthusiast user building a media center in a smaller chassis would be better opting for the 580W CM or 680W CM versions.

Efficiency of the unit is excellent, hitting a peak around 92 percent. It also is extremely quiet, making it an ideal shortlist product for a user building a new low noise system. The adoption of ultra quiet fluid dynamic bearing fan is inspired. These are without question some of the finest, high grade fans you can get today.

Ripple suppression isn't the best we have seen, although to be fair it does fall within rated tolerance specifications, so we can't complain. Crossloading results were also a little disappointing, however the demand placed on the unit can be classed as unrealistic in the ‘real world', so we aren't happy scoring the unit down for this.

Internally, the FSP design is solid, but far from class leading. We would have liked to see a 105c rated Japanese capacitor in the primary stage, rather than a cheaper Chinese 85c CapXon cap. Thankfully the secondary side capacitors are 105c rated which should help prolong life expectancy a little.

As we mentioned, the supply can be bought for £96.74 inc vat. At this reduced price it is hard to fault, if you can find it online for under £100 then we say it is definitely worth buying.

Pros:

• Looks fantastic.
• Very quiet.
• delivered almost 800W.
• good price now in the UK.

Cons:

• Ripple suppression isn't the best.
• its not modular.
• Primary capacitor could be better.

Kitguru says: A good looking, solid unit that is going to suit noise hating enthusiast users who want to keep the cost of ownership to under £100.
