    The power supply functions fine, no issues so far, but it does have some really loud coil whine. If that’s going to bother you, go with another brand

    Very nice power supply with alot of modular connections for powering various components of your PC. I would like it to have more than one SATA power cable however.

    The PSU does what is supposed to. For a normal computer with a low to mid range GPU should be ok. Don't put a high end GPU but other than that is fine.

    Solid PSU by a reputable manufacturer. My unit had an issue with the fan that caused it to make a ticking noise when it revved up.

    Good PSU misleading as 'modular'

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Works fine, a bit overkill for system; it's not completely modular even though the title implies that it is fully modular AND it doesn't say semi-modular to account for the 24 pin and 4/8 pin connectors being already connected.
