    SilverStone Strider Plus review

    5  

    Would you trust a 1,000W PSU named after a racetrack? 80Plus silver certification and Nvidia SLI compatibility does not guarantee a great result

    For an entry-level PSU with 600 watts of 80Plus Bronze certified power we're sure you won't be disappointed with this eco performer

    For budget SLI-ready capabilities this non-modular, 650 Watt PSU sounds ideal, but can it deliver the bang?

    A solid, if pricey mid-ranged PSU that delivers 700W, 80PLUS certification from a semi-modular design

    Antec has been putting PSUs together forever, so surely you can't go wrong with this 550 watts, 80Plus Bronze certified, SLI ready model?

    Can a quiet running high-performance PSU with 1,100w output and 80Plus gold certification actually beat the rest?

    OCZ bless us with 600 watts of 80Plus certified power and a noise-free voltage power supply.

    A lower-powered PSU, offering 650 watts output from big-name memory manufacturer Corsair

    More watts doesn't mean better watts. Cooler Master shows how good an 800W, 80Plus Gold certified, Nvidia SLI compliant PSU can be

    At this end of the market there's no room for error and Antec's 1,200watt, 80Plus Silver offering with SLI and CrossFire certification can't cut it

    You'd hope a quality graphics card supplier would do a good job with an 850w PSU offering 80Plus silver certification and Nvidia SLI support.

    Thermaltake Toughpower XT 775W review

    A potentially perfect semi-modular 775 watt PSU that's 80Plus bronze certified and SLI-ready, so what's the catch?

    Fractal Design Tesla 650W review

    This low-noise, low-power 650W PSU leaves us cold despite its quiet performance and 80Plus certification, non-modular design

    Nesteq Xzero 700W review

    Claiming to be efficient and quiet can this 700W PSU, with its semi-modular design, pull off a power coup over the rest?

    Enermax Infiniti 720W review

    9  

    Unsheathing this beast of a power supply is a pleasing process. Clad in gunmetal grey armour, and sporting a cooling fan the size of Bolton, it's clearly a high-performance product. The modular cabling can handle a massive number of components

    Antec 550W Neo HE review

    9  

    This may seem like a lot ofmoney to pay for a PSU that you're not going to show off. It does haveone trick up its sleeve though - it's very quiet. This is moreimpressive when you consider its 550W maximum output.

    Zalman 460W Noiseless PSU review

    8  

    Zalman and quiet computing go together hand in hand, and once this unit with its 120mm fan was installed in our test PC, the noise from the CPU cooler became more pronounced than ever.

    Nesteq Nova 600W review

    Nesteq has broken all the usual design constraints. The Nova comes in two parts: a bracket that sits in your case's usual PSU area, and a power unit outside your case. All the internal connections trail from this bracket...

    Hiper Type M 730W Low Noise PSU review

    Unlike some of the other PSUs from Hiper, this lacks modular connectors and does not come packaged with unnecessary frivolities such as plastic tool cases. The package does, however, have all the required splitter leads...

    Hiper Power 730W review

    9  

    While there's no modular cable system, this Hiper model boasts a whopping 730W output, with Active PFC circuitry built-in. You're getting a lot of punch for your money here - easily enough for a dual 8800GTS system.

    Enermax Galaxy 1,000W PSU review

    9  

    The Galaxy is the first PSU we've seen that reaches the 1,000W barrier, but is also the first to use a form factor 50 per cent larger than standard, making fitting it into a small case a tricky business with the added size and weight.
