A compacted list has been done by Tom's Hardware for the start of 2013. Check out the list here.

Many common branded PSUs are not made by the company that sells them. In fact, most companies that sell PSUs do not actually make them – rather, they are re-branded OEM products from specialised PSU-manufacturing companies. The following is a list of common PSUs and their actual manufacturers.

Antec is a well known PSU company that has had questionable PSUs in the past. Their older CWT-built models were plagued with failure of their Fuhjyyu capacitors. Since changing their main OEM for the mainstream units to Seasonic and Delta Electronics, Antec PSUs have improved substantially. They now use Delta Electronics for their high end PSU's and are very high quality.

Corsair (known for its memory products) made a big impact with their initial Seasonic-built HX series. All products since have been top notch and are among the best performing, quietest, and best value PSU's. The Seasonic models are generally quietest, but all models have excellent performance. The AX series is the latest and greatest series.

Cougar

Cougar manufactures their own PSUs.

They are relatively recent – from around 2007. Their PSUs are generally considered slightly above average quality, but individually range from average to above average.

Fortron Source (FSP)

FSP manufacture their own PSUs.

Been around for a long time, their older PSUs are average to slightly above average units, but their new ones are much better. For the price, their lower budget PSUs (such as the Raider) represent better value than their higher budget ones (Aurum).

OCZ used FSP as its OEM manufacturer for a long time. Their PSUs were of questionable quality, being based on the Epsilon model. However, they have taken a big step forward since acquiring PC Power & Cooling in 2007. The Impervio units and some Sirtec models are excellent.

PC Power & Cooling (owned by OCZ)

Silencer – Seasonic

Silencer MK II – Sirtec

Turbo Cool – Wintact

The 1kW Turbo Cool is considered one of the highest quality PSUs available; despite being one of the loudest, it is a high-quality server-grade PSU. The Silencer series is good, although their are better Seasonic built units available, that are also quieter and better value. PCP&C units are not currently sold in Australia.

Seasonic

Seasonic manufacture their own PSUs.

Long time PSU manufacturer, all of their products are very good, one of the few OEM's to still make quality low-mid power units. Seasonic units are generally quiet, high quality and good value.

Seventeam

Seventeam manufacture their own PSUs. However, the quality of the PSUs are not much better from Generics.

Thermaltake PSUs have a long-standing reputation of being average at best. They switched their OEM to Channel Well (CWT) for the Tough Power and later PurePower RX series, which have some good units. You need to know what you are buying when you get a Thermaltake, especially that they are a little overpriced.

Vantec

ION 350W/460W – Topower

ION2 460W – Topower

ION2+ 450W/500W/550W – Andyson

Some reliable budget PSUs. They are great bang for the buck in low end systems.
