Customers are saying

Customers often highlight the power, performance, and quiet operation of the Smart Series 650W power supply, along with its ease of installation and reasonable price. Many appreciate the flat cables and good compatibility with various computer cases. However, some users point out that it is not a modular design and that its size may be larger than expected.

    The power supply worked well. However, the cables were not long enough for my full size HAF tower, without adding a jumper cable.

    My old power supply literally blew up (sparks blowing out the exhaust fan) and I got this as a replcement. After having this for about 2 months, it has been a great power supply, rock solid and much better efficiency than the old one.

    I added a new video card to my daughters PC and we needed to update the power supply to handle the additional power needs. I spoke with a rep at Best Buy and they recommended this power supply. Easy to install and we have had no issues.

    The product does what it supposed to. Overpriced at Best Buy. No promo-s. Had to buy what was available immediately in a "small town USA".

    This appears very well made. The finish is nice and the cables are a good length for my big tower and there are plenty of connections for everything. It has been quiet and stable, day in and day out.

    Needed to replace son's PS that died. This provided the fit, form, function needed for the computer. BB was out of stock on the next Wattage size up, so settled for this item. It works and son is back to gaming. No issues.

    Exact fit for my Dell XPS 8300, really quiet, a little noisy during start up but after it gets going there is no noise at all. Highly recommend this company if you are in the market for a power supply for a Dell computer.

    This was a replacement for a 1kW Gold Thermaltake PS that one day didn't wake up from being turned off... I think it actually performs a bit cooler and quieter. It's enough for two (what used to be) high-end AMD video cards in Crossfire mode and a small RAID array (that was replaced later w/ a single SSD...).
