Power Supplies

The Ion SFX 500G achieves top performance in all major areas and has a fair price tag.

Fractal Design's Ion SFX model with 650W max power offers high performance, highly flexible modular cables and compact dimensions at a reasonable price.

The EVGA SuperNOVA 1000 G5 has a daunting task, to replace the 1000 G3 model which is among the best PSUs in the 1000W category.

The Fractal Design Ion+ 560P is dead silent and achieves good performance in all areas. If 560W covers your needs, this should be near the top of your shopping list.

The Fractal Design Ion+ 660P is a mid-capacity power supply featuring good performance and silent operation.

The ION+ 860P is Fractal Design's flagship power supply, offering good performance and ultra-quiet operation, even under harsh conditions.

The FSP Hydro G Pro 850 has excellent build quality, loads of connectors and compact dimensions. Is all that enough though to justify the $139 MSRP?

A solid, mid-capacity choice, the Corsair RM650 power supply has good performance and quiet operation, even under stressful conditions.

The FSP Dagger Pro with 650W capacity is among the strongest SFX units available on the market today. But is this enough to help it beat the competition?

The Cooler Master V850 Platinum has high build quality and quiet operation. Are there better options though, with the same amount?

The Corsair RM750 offers excellent performance for the price, but is only a little cheaper than the company's superior RM750x.

Cooler Master's top of the line V series unit is the V1300 Platinum, which has enough power to support a top-of-the-line gaming system.

The Seasonic Focus SGX units bring a fresh air in the SFX-L market thanks to their high performance per buck ratios.

The SilverStone ST1000-PTS has 554W per liter power density, thanks to its 1kW capacity and the compact dimensions. Is it a good option for $254 (£195)?

The Corsair RM850 power supply is a more affordable version of the highly successful RM850x, featuring good performance and silent operation.

Is a super budget PSU like the Corsair VS450 good enough for a system that has low power requirements? Is it reliable enough?

This PSU behemoth delivers up to 1800W of power with 230V input, but is it worth the hefty price tag?

The Corsair VS650 is a highly affordable power supply suitable for mainstream systems with modest needs.

Small and powerful, the Seasonic SSR-650SGX achieves good performance and backs it up with a long warranty and plenty of features.
