Who made your power supply?

The dirty little secret of the power supply market is that there are, in fact, far fewer manufacturers than brands.

There is nothing inherently wrong with that. In fact, some of the best supplies on the market are made by one company (the OEM) and marketed by another. It is, however, confusing. To help sort out some of this mess, we have compiled a partial list of the manufacturers behind the various brands.

Please note that this is a partial list and always will be. Some brands are not listed; some brands use more OEMs than could reasonably be mentioned here. Note also that the OEM behind a particular supply is not by any means the only determinant of its quality; two supplies from the same OEM, even sold under the same brand, may be worlds apart in quality. This list is only meant as a guide.

Much of this information comes from a page maintained by jonnyGURU.

UL numbers are usually a reliable way to determine who actually made a power supply, and so are included here for reference, when possible. Hardware Secrets has a bit more on this. UL numbers are not always available to us, either because the supply is not sold in the US and therefore doesn't need a UL number, or because we could not find a review that included it.
