Xigmatek NRP-PC402

Sub-$75 Mainstream Power Supply Roundup
By , Patrick Afschar

The 80 PLUS Bronze-certified Xigmatek NRP-PC402 makes a good impression right from the unpacking. Xigmatek includes a power cord, screws, and power ties in a single separate box, and the build quality is solid. Cables are sufficiently long and well-wrapped in sleeves.

In addition to the box you see above (pro tip: periodically blow out your PSU to prevent foliage from growing in the accumulated dirt), the PSU also comes packaged in a cheap little bag. Xigmatek did not skimp on the overall package, though. The NRP-PC402 comes with four Molex connectors, eight SATA connectors, and a 6-pin PCIe connector.

    1) Stop moaning about PSU.s that aren't available in the US.
    2) Where are the actual voltages for each rail? It feels like most of this test is missing!

    I can't say I've read every page - but are there noise readings anywhere as well as the occasional comment like "it's quiet"?

    Small PSU means desktop/media.... and since the conclusion was "they're all pretty similar" then noise is going to be one of the main selection criteria. So... no real help in choosing :(

    Uhm... just a newbie question :
    Are cheap PSUs really that bad ?
    I mean I've seen a lot of people basically saying that a cheap PSU will make your PC explode (or something along that note), but I've seen very few thorough reviews of cheap PSUs testing ripple, noise and voltage drops.
    Could this be an idea for a future article ?
