i currently have a 450w antec but its a 4 pin and a 20 pin, the board requires a 8 and 24 pin + why im querying about this is due to the psu making a bit of a noise, also it completely shutted down a few times, i think it might be the fan? also when i boot it its fine for a moment and then the noise starts, im sure that its the psu as i kept a close ear to the back of the case, it also did something else, but only one time, when i booted it it only gave running code at the bottom of the screen nothing else, so i dont know whats actually the problem, its been powered down for more than a month now as i dont want the system to get completely busted, i have tons of photoshop work and 3D work on it as well as some of my study material.
