thanks 'galvanized'... I'll get it straight on of these days ;-) ref:my GA-7AXP Ultra in the mobo forum... this machine has a SH-300ATX supply which I find has 'bad caps' in the o/p... I have no problem replacing them, but would also like to add some mem, drives and etc. to this box.. saw pcp&c in the suppliers list and went to look and saw Turbo-Cool 510 ATX which looks nice (?) but quite expensive... any thoughts are welcome...regards...billl

Re: SH-300ATX with G-Luxon in output
You probably do realize that when the PSU starts sending unclean current to the mainboard, those caps can/will be over worked.
The 510 is a very good unit but would be overkill for 95% of PCs. If your not a serious gamer or powering a server with over 5 HDDs a good 350~400 would serve your needs very well. The big push right now is for quiet with high efficiency. There are the GLN series from Fortron or better yet the ENP-xxxxGH series from Enhance. The well healed swear by the Seasonic S12 series of PSUs. The 380W Seasonic might be worth a look.
My favorite PSU ATM, for most any PC, is the Enhance ENP-5140GH(400W). It will Froogle for about $60, the build quality is good, it uses Teapo caps through out, just as the PCP&C 510 does, it's fairly quiet, but not as quiet as the S12s.

This last link has a power calculator and several tutorials on power supplies. Please do look over jonny's site. His review of the 5140 should be up in a couple of days. Last I talked to him, via PM, he was very impressed with this unit.
The 510 will not be a quiet PSU. If you want to read reviews on quiet power units go to http://www.silentpcreview.com/ I'm not a quiet freak myself but the reviews done at SPCR are VG indeed. They liked the Enhance units very much but were dismayed by the early ramp-up of it's fan. This is a common complaint over there
Huzzah!! jonny has posted the 5140's review. Sure looks good. Check out the O'scope's report. -
Re: SH-300ATX with G-Luxon in output
I'm in love with my new Enermax 420w. A rated 30a on the +3.3 and +5v rails and a maximum of 18a on each +12 (29a total) is plenty of power for almost any machine. Two things: First, I don't know what brand of capacitors it has (I know some of the output caps are the usual mediocre jPCE TUR series) since I haven't opened it up. Second, it's almost silent. I have to hold my ear up to it to hear it, in fact. Not audible over my ceiling fan (which is pretty average), much less my 92mm CPU fan. The fan speed knob in the rear however can only bring the rear 80mm fan up to 1500 rpm, where it moves a very light breeze. I have no idea about its efficiency.
Yeah, I'll shut up now.
You know there's something wrong when you open up a PSU and are glad to find Teapos.
Why I don't buy cheap cases!

Thanks 'galvanized'&'shroomie'... After Reading Jonny's Review On The 5140, I Ordered One...(lot Cheaper Than The 510;-) Regards...billlComment

Re: SH-300ATX with G-Luxon in output
This Enhance seems to be a decent unit, but unfortunately not availiable here. Could it be an indication that the other models like ENH-0746GB are from same quality? as those are availiable here, but certainely not as cheap than the mentioned one.Comment

Good morning everyone,
I'm trying to repair an onkyo ht-r390 that has no sound output, despite the volume being at maximum, the rest seems to work; the video output signal (coming from an hdmi input) is present, but the audio is absent. Similar situation if I send an audio signal from any input I have no output.
The firmware reported is the following:
M:1.00/11107BLP
D:?.??/????????
O:1.00/11107AL
The DSP firmware given the question marks seems corrupt.

I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
I bought this from an eBay seller but unfortunately they only had one
I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
I bought three of from them to also make battery packs with this output power limit in mind
I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery... -
Looks like I may need a little help from the PSU experts (or anyone really!
) I have a Corsair CX750M (Model 75-002019) that I picked up for free about 4 years ago. This is the PSU:
So here’s what’s strange about this one: it appears to work normally (normal output voltages) and any PC is stable with it. However, after a while (typically 10-20 minutes, but time can vary depending on the load), there is a sweetish smell of burned magnet wire insulation emanating from the PSU. Upon opening the PSU after this happened (many times), I was able to confirm... -
It has been a long while since I posted here to ask anything....hope you can help.
I have this Samsung power supply that uses SPC1012T as driver for the PFC and it's giving me a problem that I can't narrow down though I've troubleshooted and fixed hundreds of boards similar circuits.
I am attaching a schematic from a different Samsung board, but the topography is very very similar if not 100% the same and it uses SPC1012T, which BTW is a pinout match to UCC28063 for which there's plenty of information. I haven't confirmed they are functional equivalents, but I strongly... -
I have here a Magnum IA.100 which belongs to my parents.
The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.
Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.
