The Antec Smart Power may be cheaper. But the Seasonic S12 is still superior. It is one of the quietest, or the quietest PSU with a fan. It is also rated and tested to be up to 85% efficient where as the Antec Smart Power is rate at 70%. The higher the efficiency, the lower the power draw from the A/C outlet, and the less heat will get dumped in the PC case. As almost everyone knows, heat is a probably especially when overclocking.
But not everyone is willing or can afford to spend money on a premium quality PSU, which is why I usually list cheaper, but still good PSUs.
true true, but if a 44 dollar PSU will cut it, especially that system, ill get the cheaper one cuz that thing isnt going to be upgraded soon(old socket, old gfx card) so why even spend the extra cash? thats my ethic. if u only need 44 bucks to make it run just was well as spending 65, whats the point.
its like this, why buy a zalman if the stock cooler will do the job?
The PSU fan does exhaust heat from the PSU and the case, but heat is still emitted by the PSU and some of that heat gets transferred to the inside of the case.
Certainly, but that doesn't matter. The reason it doesn't matter is that more heat is blown out of the case by the PSU fan than the PSU puts into the case to begin with.
Efficiently cooled power supplies with inefficient power conversion will have fans with higher airflow, so they'll cool better. More efficient power supplies will have slower fans so the cool less. The balancing factor is how much heat the power supply "leaks" compared to how much it "exhausts" and the net result is this: Efficient power supplies are able to stay cool more QUIETLY while reducing your ELECTRIC BILL, case heat isn't a significant issue because hot power supplies use faster fans.
