Specs

Seasonic is one of the largest power supply manufacturers in the world, selling PSUs under its own name and making them for other companies, such as Corsair.

The 850W M12D has modular cables, which is sensible considering its huge number of connectors. It has four 6+2-pin PCI-E connectors, eight SATA and eight Molex plugs.

The 12V supply is split over two 40A rails, with a maximum combined power of 70A. In our tests, the M12D was rock solid and blissfully quiet. Efficiency was also a highlight - it was 87 per cent efficient at half load and 86 per cent efficient at full load.

If you need more than 800W from your power supply, you're spoilt for choice, but the Seasonic M12D is leagues ahead of its competitors. It may be a tad expensive, but it's still great value for those with top-end PCs stuffed full of high-end components.
