just about every PSU under 1000w has only one 12v rail including the OCZ linked by jyjjy

"just about every PSU under 1000w has only one 12v rail including the OCZ linked by jyjjy"

are you kidding me? there are plenty of 2-3-4 rail psu's under 1000w. Antec's entier range alone is basically made of multiple rail PSU's.

a good 350w psu will run that card. a full system with that card running furmark uses just over 200w from the wall.

no, I am not kidding. this is the part where I prove your noob knowledge on PSU as well as all the other subjects you have been posting your incompetent opinions on


In most cases, multiple +12V rails are actually just a single +12V source just split up into multiple +12V outputs each with a limited output capability.*

There are a few units that actually have two +12V sources, but these are typically very high output power supplies. And in most cases these multiple +12V outputs are split up again to form a total of four, five or six +12V rails for even better safety. To be clear: These REAL multiple +12V rail units are very rare and are all 1000W+ units (Enermax Galaxy, Topower/Tagan "Dual Engine", Thermaltake Tough Power 1000W & 1200W, for example.)

Nearly all multi rail PSUs use OCP to get there. (yahoo the term if you don't know what it means.)

The Antec that JY posted has much cheaper shipping. The difference between the two are very small. (The seasonic is a good one, but with shipping and no rebate comes out costing more then the others.) I prefer the Antec due to not worrying about a rebate.

That OCZ unit is decent but this Antec is a better brand and has 84 more watts of the +12v rails;

It's also initially cheaper with shipping taken into account(but lacks the rebate like the OCZ unit.)

When I read the stickers I see 384 watts for the Antec on the +12 volt but 450 watts on the OCZ. The lowest number on the Antec sticker 534watts is including +3.3 and +5 volts.
