Originally posted by kevin! View PostI do not think that everything is bad XD,
In my server (a Pentium e2160) has an average of 450w media magic, he broke one fan blade, because the blade does not jam the fan and turned , was working 24/7h for 2 weeks, when I discovered that the fan was not working, the PSU was very hot, but still worked (a lot smelled burnt by the overexertion circuit), I put a new fan and currently works the 24/7h and carries himself four months non-stop, no capacitor bloated!. Take capacitors Micon, not if they will be good, but I take it that overexertion, bad must not be XD.
leave photos of magic media source.
in the second photo, two resistances are seen to have been working at very high temperature, the PCB looks obscured.

Do anodia capacitors are good? fourth photo.
Originally posted by kevin! View PostAlso I did not realize that the silkscreen of the PCB media magic puts atx350w average psu. XD

Re: Recapping MSI 845 PRO
Originally posted by Pentium4 View PostIt probably has 13007 switchers too which is usually what blows up those el cheapos. You're lucky if you get a 20A rectifier on the 12V for those types of units, and they usually only use a TO-247 schottky on the 5VLast edited by lexwalker; 07-07-2013, 12:12 AM.

The burn marks near the controller may indicate that the 5VSB is possibly on its way out. I wouldn't trust that Media Magic PSU for anything newer than a Pentium 3 computer. It's a gutless wonder. Even though it has worked for that long, the ripple it puts out stresses the motherboard capacitors and hard drives a lot. I'm surprised power supplies are that expensive in your country. As far as I know / have seen, you can get similar gutless power supplies for under 15 Euro.Last edited by kevin!; 07-12-2013, 03:29 PM.Gaming pc:

Re: Recapping MSI 845 PRO
Ultrafast recoveries might not add that much to the heat output if the rest of the PSU is designed well enough.
Originally posted by Pentium4 View PostSurprised the Fcon made it that long! When I bought a BFG PSU a while back filled with Fcon caps, I used it as it was for about 3,000 hours and then I recapped it. I've never seen Fcon in a voltage doubler
The PSU was designed nicely otherwise. 820uF/200V CapXon LP primaries, TO-3P 13009 switchers, half-bridge topology, 10A bridge rectifier without a heatsink, 42 size transformer (yes, size 42), STPS2045CT x2 for the +5V rail, STPS3045CT x1 for the +3.3V rail, MUR2020CT x2 for the +12V rail (yes, ultrafasts in parallel), nice and thick heatsinks, 3300uF 10V Teapo SC x2 for +3.3V filtering, 2200uF 10V Fcon GL x2 for +5V filtering, 1000uF 16V x3 Fcon GL for +12V filtering, 220uF 16V Fcon GL x1 for -12V filtering. There was a PI filter coil for every rail including -12V, and two PI filter coils for +5VSB. The small capacitors were a mix of Teapo SC, Fcon GL, Fcon GF, and Fcon KM. It had two AS339P ICs mounted on a separate PCB and a KA7500B IC for monitoring and PWM control. It had dual +12V rails. It never kicked out hot air or even warm air in the time I used it.
My guess about those Huntkey power supplies (along with Bestec and all supplies lacking OPP, I think Unique theorized this as well) is that the problem isn't that they don't have OPP, it's that their OPP is set way too high, which is why they explode when pushed past their limits. It makes sense that Huntkey would set their OPP so high because they lie about their rating so of course OPP is set to be above the "peak" value rather than continuous...
Not to hijack the thread though. Kevin, are you saying the currently PSU installed is failing, if I read correctly?

Re: Recapping MSI 845 PRO
I didn't know there was a PIII version of 845.
I thought 845s were Pentium 4.ASRock B550 PG Velocita
Ryzen 9 "Vermeer" 5900X
16 GB AData XPG Spectrix D41
Sapphire Nitro+ Radeon RX 6750 XT
eVGA Supernova G3 750W

The socket 423 is much like the 370, but different sockets.

It may look a lot like S370 or even S462 but it's a completely different thing...
CPU therefore has a kind of welded adapter. and the performance was sad
compared to AMD K7.
RJARRRPCGP said he did not know it was compatible with the Pentium 3 with chipset 845,
and I said, The socket 423 is much like the 370, but different sockets and architecture. Because I think confused.
