I have had a Topfield TFPVR5000t since March04. (The Toppy is the best toy EVER, IMHO)
What is your opinion of the PSU and the caps on it, and the caps on the main board for that matter?
I notice alot of them are "Sam Young", while the big one is a "Sam Wha".
I open it up regularly for HD removal/quick-transfer (I've got a WD250 in it) and do a quick visual inspection of the caps each time, just for safe measure.Last edited by willawake; 01-07-2006, 05:17 PM. -
Re: Power supply build quality pictorial
I had mine since early 2005. Topfield must have later gone onto the cheaper Samxon capacitors for the mainboard, compared to your earlier one. The components in the power supply were quite decently sized, and has been fine for over a year, despite running a little hot.Originally posted by cods69Last edited by willawake; 01-07-2006, 05:18 PM.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment

Re: Power supply build quality pictorial
I've had bought 300W Maxpower/Everpower PSU as a replacement for SkyHawk 250W - but it was weaker
and the voltages were bad - so I promptly bought DTK PTP-3007 and sold that crap.

Re: Power supply build quality pictorial
my 250W Channel Well CWT-250ATX is approximately 12 years old. This PSU is so old, the 92mm fan blows into the computer case instead of into the PSU.
Primary caps are 470uf Matsushita, secondary side is a forest of Fuhjyyu... not one appears bad. This PSU was in regular use up until a month ago.Last edited by willawake; 01-07-2006, 05:21 PM.Comment

Re: Power supply build quality pictorial
Can't be 12. There was no ATX before 1997 (IIRC). And I see "98" on the transformer.Comment

Re: Power supply build quality pictorial
I guess '98 would be about right - I only got that unit and a 10gb IMB hard drive a year ago in exchange for a Fujitsu 6.4gb hard drive. It belonged to a friend, who bought the case it came in well before I'd even met him.
As it turned out, the IBM was DOA so I'm not sure I got the better part of that bargain

Re: Power supply build quality pictorial
Notice the nice substantial heatsinks on the Deltas (and O/P trannies) and the Sparkle? Ya gotta keep the junction temps on those O/P rectifiers and power MOSFETS (possibly power transistors in the Sparkle) within reason. The power ratings are real on those.PeteS in CA

Re: Power supply build quality pictorial
Did you also notice what appears to be a large burnt spot on the above Sparkle? I only noticed it after I posted the picture here... As far as I know, the PSU is still operating normally.Ludicrous gibs!

Re: Power supply build quality pictorial
Was it caused by the larger resistor that's standing up? Because in either a 300W or 350W Fortron/Sparkle, I found that such a resistor was dissipating almost exactly its max power rating, either 5/8W or 1W. Aren't resistors supposed to be rated for at least twice their operating power?Originally posted by doodComment

Re: Power supply build quality pictorial
Yes, I did see that. It looks like a 1W or (more likely) 2W. It could be disspating its rated power or a bit more, or it may simply be mounted too close to the PCB. Normal design practice at places I've worked at was to mount resistors 1/2W and higher spaced off the PCB to avoid scorching the board. Good design practice would be to use resistors at ~70% or less than their reated power (taking into account the operating ambient temp. US mil-spec requires 50% max.PeteS in CA

Re: Power supply build quality pictorial
Nahh, it was just for fun... And to have an emergency extra PSU at hand...Originally posted by Newbie2
I already recapped it, See here...
The missing fan was because I put a 92mm fan in the bottom of the PSU instead, to reduce noise. And because the 80mm one started to fail and I had a 92mm one just on my bench
That PSU came from a real cheap case, has powered a friends comp a few months before he got a real PSU, and after that my brothers till the caps failed and it would no longer turn on..."The one who says it cannot be done should never interrupt the one who is doing it."Comment

Re: Power supply build quality pictorial
FSP700-80GLC power supplies as research have shown are 700W power supplies.
Maybe they used the board for the FSP700-80GLC but changed the components?Last edited by willawake; 01-07-2006, 05:33 PM.My gaming PC:

Re: Power supply build quality pictorial
Probably. The protection circuitry board is also marked "FSP700-60GLN." Not that I need the extra power
The OST caps worry me a bit though.Comment

Re: Power supply build quality pictorial
The heatsinks in the 300W P/S are larger than the 400W? Puhlease! And there is no fr
ing way those heatsinks in the "600W" unit are good for 600W continuous! 200W continuous might be pushing your luck.

Re: Power supply build quality pictorial
I trust Fortron to rate their units more or less accurately - this one's supposedly 85% efficient, so the sinks wouldn't need to be quite as big as my maybe 65% efficient 530W with monster heatsinks. I've seen Tom's Hardware pull the full 700W from Aopen's version of the FSP700-80GLN too without issues. The sinks in that one are even smaller to allow the 120mm fan. Not sure about the 600W rating myself, but I am quite sure it'll do more than 200W.
Forgot to mention earlier that topmost sink is bolted to the case. I really need a digital camera

Re: Power supply build quality pictorial
looks like my fsp300-60gt.
7 years of 24/7/365 and the yec caps are just starting to go.
not bulging or leaking.just more ripple than i like to see.wasnt causing a problem yet but i will recap anyway.found during a routine cleaning and pm .
confirms that bad qc may be the reason for bad caps.yec are well known crap but we have some here with lots of hard hours on them that are just now failing.
btw i see a few fsp psu on sale at 22.00.
i think the store ordered some so expect a full report :-)Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
Assuming... -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
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... -
Good day.
I have an AC/DC -> DC PWM (rectifier + 555 buck converter) power supply with MDF11n60, which is getting very hot.
The input is AC from a transformer and the output powers a 24v dc fan. The power supply is used to regulate the speed of the fan.
After several runs on the bench power supply I noticed that the mosfet is reaching 80+C*. The mosfet reads fine on component tester, the thermal paste is changed, the fan is cleaned and with freshly oiled bearings.
When powered directly from the bench psu, the fan takes ~0.7A on 12V. The current consumption is similar... -
More Lo-Fi speakers and another DIY surround repair. The patient this time: a pair of Philips F9217L-50R speakers from a budget Philips rack/component system from the '80's. The system belongs to my brother in-law… or actually his parents. However, they didn't want it when they moved houses and he liked it anyways, so he ended up keeping it. It's a pretty cool-looking vintage system with a wood/veneer cabinet and shelves for records and cassettes. Unfortunately, I didn't get a chance to take a picture of it or get the model #'s (but maybe next time I visit, if anyone is curious?)
