    The power supply is one of those part of the computer you don't want to neglect. But when building a low-cost PC, you can either buy a case with the integrated PSU or buy a rather cheap case with cheap PSU. Pair this Power Supply with an Antec 300 and you've got a kickass combo.

    400w are more than enough for most low-cost PC and being made by Corsair, you know you get good quality and a good efficiency.

    Would definitely buy again for a low-budget computer.
