hey man, welcome aboard.


i owuld say earthwatts perhaps because of a slightly newer design?

it doesnt have all the plugs though, so you may want to use the adaptors that came with the card

i dont like recertified for psu, who knows what happened to it before.

although out of those? the silencer is the toughest of them all.

the kingwin is not too shabby either, but doesnt touch the other two mentioned


why not go for a corsair 850? actually 750


your cards will eat around 300 watts in normal gaming and perhaps

400 under 'stressed out situations'

so you have to take in account another 150-175 watts for the rest of the system, not overclocked

thanks man.

anyways the PC power and cooling i have seen people run a GTX 470 SLI on them so i feel comfortable getting that.
the kingwin 850w i was leaning on but idk if it's a quality PSU and idk if it can deliver all of it's 850w. it uses super flower tho which i heard makes good stuff.

i can only spend 90 bucks, im super broke

i actually had a 700w OCZ fatality but im assuming it's a POS since it freezes or reboots whenever i game.

no worries maite.

you in the states right?

maybe get rid of one 465 and the ocz till they still have some value?

but yeah, the silencer, if its fine out the box, itsa brick. love those things. a bit older design,

not the greatest efficiency in the worlde,but still.

the overload tests are very important.

a psu with no top end protection will continue giving till it blows. and when it blows? ouch. but even before that, the current

will go super dirty, scopes crazy, you get the idea :p

How about a XFX 750W PSU? They're supposed to be the same build quality as Seasonic's M12 class, and received a fantastic review from jonnyguru.
