    Re: my dual p3 pc is dying

    ok well i am glad i dug up that 300w psu (i didnt realize i had it). cuz now everything is working again. but i am going to post internal pictures of the liteon (uses ost caps) in the build quality pictorial later today...so was it the crappyness of the psu or the missing -5v that was the problem.
    and the mobo (a TYAN THUNDER LE-T) has mostly rubycons. so im not worried about that...

      oh, also: why does this enermax psu get REALLY hot air exhaust? it has extremely high-airflow dual fans, which are super noisy, and blow lots of air, but the air is very hot. and the hot air is from the psu itself, the air coming out of the case fans of the pc is barely warm. but the psu runs hot? is that bad? (no bad caps in psu i looked)

        Probably just a low efficiency PSU. - Lots of heat losses.

          ok so its not like its gonna overheat due to crossload of having heavy minor rail load and low load on 12v?

            I dunno.
            Enermax made lots of different PSUs.

            Why don't you compare amps/rails to the old 1U FSP?

                Could also be running hot from dust. How old is the PSU? I've known some PSUs to blow out hot exhaust air when they get dusty
                I love putting bad caps and flat batteries in fire and watching them explode!!

                    What switching transistors does it use? Is it on mosfets or bipolars? If it's on bipolar transistors, the snubbers have either gone bad or have been poorly designed in the first place. Unfortunately you're going to need a decent scope, an isolation transformer and some patience to calculate new ones if needed.
