if you wondering about fortron, they make psu's for the companys like OCZ check the psu guide for a better list, but FSP makes rock solid units, under their own name or under other names, they also offer a better warr then most other companys, 2years dirrect warrinty, most others give you one year at best Or make you deal with the place you bought it for warrinty service.
I have a 400watt fortron saga seirse psu runnin 4x hdd's, 2 burners, x1900xtx OR 8800gt(gt is in being rma'd, it was over heating when underclocked with fan at 100%) cpu is an OLD windsor 256, 3600+@2.55gz, 4gb wintec ampx ram at 2.27v(1022mhz, stock is 800)
psu dosnt even get warm under HOURS of gaming, i can play any game you like without the psu getting hot, dispite the cpu having high draw(shitty 3600 90nm chip.....) oh yeah, also ght 6 lighted case fans(lighted because i had them and they worked....)
honestly, fortron rocks, and you WANT your psu to be EPS12v because most new good boards have 8 pin 12v power connectors for the cpu, aka eps12v, the ones i listed are such
there where others i could list theres a seasonic but its only 650watt, and you seem to be very set on 700watt range.
but remmber this, watt rating dosnt mean much really, amps matter, watt rating had no set standred everybody has to follow, if you read specs of some even named psu's you find that they can only supply tha advertized wattege if they are running inside a refrigerator or on the south poll.......its quite frustrating to be honest
iuf you need amps, check out ePower units, their 550watt atx/2ps12v unit has 20amps per rail on 12v(combine its 38amps) and ePower is just OEM topower, topower make corsairs psu's as well as MANY of the other rebadges you see on the market, they are the same class as fortron, high quility, you just pay less for them if you buy dirrect insted of buying rebadge and paying for a name.
heres the 650watt version

i have use many of both brands as replacements in servers and high end workstations, and, well you cant beet them, price to quility they can go against units you pay 3-4x as much for(hell many times they make those units and then who evers selling them just re-badges them.....)
