Also, the PWM chip on that Pro Power 250W power supply is a TL494CN.

Re: Is an L&C power supply suitable for a Celeron 2.2GHz PC?
everel, that athena is one the the biggest POS' i have seen. i think i puked in my mouth looking at that
. and to think i thought about whether athena was good or not... tho low price told me not, was i ever right! complete shit, even worse than a deer...
newbie2-
good job on the enermax! much better than the l&shit will ever come close to being e it instead if you can.
as for the piss-power...
that is the wimpy-ist heatsink (not plural!) i have ever seen. one coil, few guts, i think i only saw 2 diodes, not 4. what a POS it is. maybe good for 75w on a good day...

Re: Is an L&C power supply suitable for a Celeron 2.2GHz PC?
more on the athena:
i bet it had wimpy heatsinks. pics of that please, i need more to laugh at.
no x/y caps
1 transformer
thin wire (i bet you had an easy time cutting it LOL)
few caps, and what is there is tiny
lots of jumper wire
i take it back. the assthena is worse than the piss-power!Last edited by ratdude747; 08-06-2009, 11:13 PM.sigpic

Re: Is an L&C power supply suitable for a Celeron 2.2GHz PC?
That Pro Power 250W is missing its secondary side heatsink and diodes, since I removed them as soldering practice back then. But, its secondary heatsink was wimpy.
The Enermax 300W power supply I had was put into my brother's computer, he used to have a "The Best Power" MT-500P 500W power supply. He complained of random restarts once in a while, so I thought replacing the power supply might solve the issue. It will also be a test for the Enermax 300W power supply, to see if the new capacitors I installed will do their job. I have new pictures of that "500W" power supply that I'll post here tomorrow.My gaming PC:

Re: Is an L&C power supply suitable for a Celeron 2.2GHz PC?
Newbie2 - Your modifications to the L&C look good; however, Nichicon PW on the primary side is overkill and may actually decrease reliability a bit. Why? because they are low-ESR, so the inrush surge current is going to be limited only by the thermistor, if there is one, on the primary side. Depending on the instant when it is plugged in, it could either:
a) blow the fuse
b) blow the primary-side bridge rectifier.
Anyway, if the system is going to be always left plugged in, and if there's no problem at the moment, you can just forget about this possibility for now, and be happy. Everything else looks bulletproof.Comment

Re: Is an L&C power supply suitable for a Celeron 2.2GHz PC?
My L&C power supply after a good period of use, and I upgraded the video card in the computer to a recapped (Panasonic and Rubycon capacitors) Diablotek ATI Radeon 9600XT 256MB DDR AGP 8X video card.
The stock speeds of the video card were 400MHz core and 200MHz DDR (400MHz). The 9600 chip on the video card is the 9600XT chip, RV360 (checked by removing the heatsink), so with ATITool I put the core speed up to 500MHz, the standard speed for the 9600XT RV360 chip, and it works without any issues (no artifacts in 3DMark03, Rainbow Six 3 Raven Shield, and the CoD4 PC demo). The DDR chips on the video card are of the cheap elixir brand and are running at their rated speed.
My L&C power supply is showing no problems running the video card.My gaming PC:

Deer power supplies have good designs, but the components that they use in their power supplies can be shoddy in quality, especially the capacitors and the fan.My gaming PC:

The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles... -
These cheap non brand capacitors at it again
Last night we had a power outage [ long drawn out trying three to come back up before going out completely ] and when I went to turn the DVR camera recorder back today no go 3 bad capacitors ( one capacitor no ESR reading on DVR board the other 3 capacitor on the power supply board over 40 ohm this is not a misprint ) on the external switching power supply and one capacitor on the DVR camera recorder board where the power supply that goes to the hard drive disk is
Well at least I have the cameras back on line I to try the... -
When I originally started with my DVR recorder it had 4 individual switching switching power supply’s that were sh*t so I bought a 7 amp 12 volt switching power supply and modified the output plug and put a four output power supply cable to match the input power supply cable inputs
Which worked for over 14 years until a few days ago when the cameras went dark no picture anymore well it turns out now the switching power supply has stopped working altogether now so I have to troubleshoot what has happened to this power supply more later on today what I found

FAST MODE vs NORMAL MODE
I have recently acquired a HP 6632A DC power supply. I am just beginning to use it and I have been reading the manuals for it. It is the first power supply I have ever owned or used. I am a very beginner hobbyist and do not have an engineering background, as may be obvious by my question...
I can't seem to understand what the actual use is for the 'Fast Mode' or the 'Normal Mode' on the power supply. Although the manual states what the two modes do from a engineering/technical standpoint, I don't know enough to understand what it all means,... -
Dear Members,
My DC linear Lab Power Supply does not display the current and voltage correctly. Thus, I am going to connect an Ammeter/Voltmeter Module to the DC output of the power supply. Then, a load will be connected the takes about 1-5volts with 0.1-1.5Amps.
But I heard If I connect an Ammeter to the output of the power supply, then the Ammeter module is not isolated from the power supply so that the Ammeter can damage the power supply.
Is this true?
Thanks
I have attached the photo of a sample Ammeter module that I am going to buy....
