Some common rebadged to powers: BFG, Muskin, Ocz, scythe, Tagan

The OEM: The most important factor to look for in a Psu is the OEM or original equipment manufactures. Most Psu's are rebranded OEMs, and very few companies make their own FFXIV Gil PSUs. Here are some OEM Guidelines’: OEMS that make very good PSU's:

Sea sonic (usually the most expensive Psu's are sea Sonics, sea sonic also sells their own PSu's, but many times it’s better to get a rebaged sea sonic instead). Common brands that use Sea sonic: PC Power & Cooling, Corsair, etc.

Forton/Fsp/Sparkle(owned by fsp)(they have a controlling interest in 3Y). They sell their own psu's as well. But here are some common rebadged fsp Psus: OCz, Sparkle, Zalman

Topower/epower (to power’s retail brand) These Psu's are very good, and usually a lot cheaper then sea Sonics, and they are more common. Some common rebadged to powers: BFG, Muskin, Ocz, scythe, Tagan.

Enhance (many reputable brands, but I don’t know much about enhance) they sell their own psu's as well. Common rebaged enhance PSU's: akaska, high wattage cooler masters, Silverstone zeus, strider, and element series, xclio stable power.

Worst of all though, modular plugs utilize delicate pins that can easily loosen, corrode, and burn, creating the potential for a major system failure.
