    In need of a reliable PSU

    Hi guys, I'm looking for help on choosing my next Power supply. My 1 1/2 year old Rosewill has one or two bad Koshin caps and it can't handle a new graphics card load even with 34A, and makes nasty bug zapper sounds from just the load my 6600GT puts on it.

    Could someone point me to brands with known high quality caps and are tested well?
    Thanks!

    Re: In need of a reliable PSU

    Known high reliability caps are from my point of view only in Seasonic and Seasonic build PSu`s used ATM.

    So i would suggest to checkout Corsair or Seasonic`s offers if there is something, who fits your budget.

    If the general quality and endurance is your point and nois is not your concern, may be PC Power & cooling may have some offerings you want (of course, these things are $$$$$$) or may be Silverstone. This brands do not use the best possible caps, their caps are even innthe badcaps list.
    But up to now, their repetition is untainted.

    Any way, checkout http://www.jonnyguru.com for "real" reviews.

      Re: In need of a reliable PSU

      Most power supplies do not use the top brand Japanese capacitors. Just about all of them use bad caps that are not suitable for motherboard use, however in many cases some of them are fairly good when used in power supplies. The main capacitors that I am talking about are the Teapo ones. When these capacitors are used in the VRM of a motherboard, they are simply no good and fail pretty quickly. However I have not seen many complaints about them when they have been used in power supplies.

      I do not know the specifics as to why this is the case, however what is really important is to buy a power supply that is of decent build quality. Therefore even if the capacitors do fail eventually, it is worth a re-cap.

      Last week I bought a Fortron power supply, they are known to be very reasonably priced and are decent power supplies. However they use Teapo caps.

        Re: In need of a reliable PSU

        Certainly, Teapo do not fail in all PSU`s, but i have a lot of OEM FSP`s seen, where all caps failed, even all the Teapos.

        So Teapo is crap, period. The only difference i see, that most of the higher end PSu`s using Teapos are very very good cooled.
        The PSu`s with failing ones, have had lowered cooling due to noise constraints by sacrificing endurance of this caps.
        But this comes with the noise penalty, which can not avoided if Teapos and similar not top notch caps are used.

        Hence i would advise the usual power hungry gamer with noise in mind the Corsair or Seasonic units, which do not skimp down on the caps and do not sacrificing noise concerns or endurance.

        For the enthusiast, or server duty, where noise does not mater and the additional powerful cooling is needed anyway, the higher end Teapo using & expensive PSu`s may be even the better choice, above all what Seasonic has to offer with the S12 Series and similar builds.

        It is obviously, that Tepos used by PC Power & cooling are not better then those used by FSp or any may be even lower branded PSu maker.
        The difference is, that the engineers have had the spec`s of this caps in mind when they designed the unit.
        Teapos are sure a win- win situation if someone want to make a high power, heavy duty PSu with a big cooling capacity.

          Re: In need of a reliable PSU

          I think I will order one of the PC power supply's.
          So even if I do have problems, they look to be more honest about their warranty. The act high and mighty in their "power supply myths exposed" article, when they don't even use high end caps? That makes no sense to me.

          It's a shame these days that no PS company is using quality caps. I wonder if that day will ever come, or even a day when they use solid capacitors.

          thanks for help

            Seasonic uses good quality capacitors (UCC)

            Corsair PSU's are made by Seasonic, they come with longer warranty
            One of the latest models also have a solid cap on +12v

            One or two of Corsairs latest builds have been CWT, they look good too, more info about this can be found over at JohnnyGURU, they even have Corsair reps there...

            HardOCP also makes very good PSU reviews

              Something I've been thinking about doing, for my lower-end PSU requirements, was to get a low end FSP unit, like their 400w OEM unit. Test it once, then, buy the appropriate top quality Japanese brand caps, and put 'em in it new. I mean, the caps are really not that expensive, and you'd be nowhere near the price of a high quality unit like a Seasonic. That way you'd have a still inexpensive, new, PSU with good caps.

              Just thinking out loud here.
              A man convinced against his will is of the same opinion still.

                Re: In need of a reliable PSU

                Just get a good quality supply test it to make sure it suits your needs then recap it. You know what they say if you want something done right do it yourself. I feel that its really futile to find a supply with all top brand caps out of the box.

                Plus even is you did find one manufacurers can switch the internal components from lot to lot which means just because one box has all UCC caps that doesn't mean the next box will.

                Even my Antec which is a good quality supply had Fujiyuus and Koshins inside I replaced the general purpose Koshins with UCC KMG or KME can't remember and the low ESR Fujiyuus with Panasonic FC's. Ironically enough though the input filters were Panasonic go figure.

                It was a little tough to get the 12.5mm diameter FC in the 10mm space but the supply is just fine with 2 of the caps 2 to 3 mm off the board.

                The next issue was getting the cover back on because getting the wires to fit back but after a little Feng Shuing its worked out .

                  It is probably not a bad idea at all. That is what I am going to do, except I do not have the cash for new capacitors right now and I do not feel like changing parts in my brand new power supply just yet. After all, the Fortron I have now is much better than the Codegen that I was using for the past 5 years in my PC.

                  Actually I should check out the condition of that Codegen in terms of the caps. It served me well considering it is regarded as a crap power supply on this forum.

                    Re: In need of a reliable PSU

                    Codegen PSU`S do not only have crap caps, they are very unsafe PSU`S too.
                    In the soket A era i build several systems with those Codegen PSu`s, and they killed a few of those systems, when there was a need for more power hungry components.

                    Since them i have laying around a few of them in the junk bin, but never intend to do anything with them, beyond cannibalizing some components.

                      Re: In need of a reliable PSU

                      I probably could manage to do it myself, I just don't have the tools or the experience. It's kind of like soldering copper pipe, you can screw up on pipe and cut off the bad ends easy, but not with a circuit board.

                      If it was a motherboard I would at least try, but I would have lots of trouble with a PS with how cramped they are and all the wires in the way with hands my size.
                      My motherboard seems to have done it right, although it is made in Japan. Rubycoon, Sanyo, and I think I saw something called HHW or something.

                      I wish I had the money to have a back up PS so if I found someone to do it for me, I could get along without it.

                      But could anyone tell me if my +5V lines are in spec? They seem to go all over the place.

                        Re: In need of a reliable PSU

                        Recapping a PSU is pretty easy compared to a mobo. It's a single-sided PCB, so there are no inner traces you can mess up.
                        The parts can take lots of heat compared to those on a mobo, and you don't have those large ground planes (some of them are inside the PCB in a mobo), so there's not much you can do wrong (even with cheap tools).
                        Just make sure the new caps are the right size.

                        Those Speedfan readings are probably rubbish, I doubt your system woud run in the first place at those values. Better use a DMM and/or a scope.

                          Re: In need of a reliable PSU

                          Well i know what you mean, i don`t like the usual tight mess in PSU`s too and i donΒ΄t fell it encouraging to mess around with them.
                          This is not a question to be a pro or not, it simply is hard work.

                          But if you have the time, and are willing to spend it physically working, then i have no doubt that you can do a unsuccessful recap job.

                          Just make some pic`s, or drawings in the process of disassembling in case you forget it. If a wire must be desoldered in the process, just make sour to document where it belongs too.

                          You have to pull the whole PCB from the case, there is no other way to get this job done.
                          The soldering is not difficult (but you need a iron which can handle big solder points) and you can fix it, if the first try seems to be weak. Just let the solder point cool down a while and try again.

                          I think your 5v line is far out of any regulation, even with the known inaccurate reading of a on board voltage sensor in mind.

                          For an tight budget, i would recommend one of the lower priced FSP`s as a cost effective replacement.
                          Sure, not the top notch caps, but from my point of view, they last a long time.

                            I did crack open the power supply today and none of the caps have bulged, not bad for a five year old power supply. Coincidently my system from the Socket A era. However since I added a second hard drive to my system, my portable hard drive would not work correctly. Essentially it was not getting enough power from the power supply.

                            Fortunately I was able to buy a Fortron unit for a very good price, sure it's not the best, however it is a 400W unit rather than 350W and I can see physically that it is a superior power supply. And what do you know, my portable hard drive works perfectly now!

                              I haven`t known it either until things have had gone worse. Probably those Codegen do not have OPP, so it went foo.bar as there was the need for an GF5600.

                              They arenΒ΄t capable in putting out more then may be 150w to 200w if you are lucky.
                              I would compare them with the famous L&C Deer, they are similar build like the better ones of these.

                                I went with a 610W PC power and Cooling PS.
                                The speed fan reports the same crazy +5V on this one too, I guess it must be the program.
                                any idea on who makes the caps in it? KY?
                                I've seen the same style on a power regulator board proprietary to my motherboard.

                                  Those are UCC/NCC caps. They are good caps. I've had good luck with recapping Antecs and FSPs with good caps and they work great. My power needs are usually small, though. I don't game and rarely have more that 3 drives in a system.

                                      Re: In need of a reliable PSU

                                      I am now using supplies with 120mm fans. They seem to run cooler, which is much better for less than premium caps. The larger fan doesn't spin as fast, so the noise is also reduced.

                                      I can't see any valid reason to buy supplies with 80mm fans.

                                        So i would suggest to checkout Corsair or Seasonic`s offers if there is something, who fits your budget.

                                        If the general quality and endurance is your point and nois is not your concern, may be PC Power & cooling may have some offerings you want (of course, these things are $$$$$$) or may be Silverstone. This brands do not use the best possible caps, their caps are even innthe badcaps list.
                                        But up to now, their repetition is untainted.

                                        I'm currently using a Silverstone ST-400 (400W) PSU. It comes with 3-year warranty.

                                        Might be worth a try.

                                          Backlight strip quality, Amazon vs Ebay vs ShopJimmy. Is there really a difference?
                                          by DXseekerMO
                                          Hello everyone!

                                          Recently I've noticed that some ShopJimmy backlight strips don't have double-sided tape installed upon them when an application calls for it, and I must purchase the tape separately. In a recent chat conversation with a customer service agent I told them if this tape wasn't applied when it was called for I would begin to consider ordering my backlight strips elsewhere. It looks like this time may have come.

                                          I recently got a TCL 65S4 with bad backlights. After looking at the SJ listing here: https://www.shopjimmy.com/tcl-jl-d65...365as-m-led-ba...

                                          Hi,

                                          Back after a long hiatus with some old power supplies that need repairing. I've recently picked up a couple of 386SX systems, two 486DX systems, a SiliconGraphics Indy and an iMac G3 that either have verified leaking capacitors in their power supplies, or are likely to in the near future. For the sake of simplicity, instead of tackling all at once, I'm starting with the 386's and one of the 486's.


                                          The 386's power supplies are Seasonic SS4040A's, with caps that are visibly leaking, and 9 replacement caps per unit are required. Most appear to be from the Rubycon...

                                          Light that has a bug zapper in bottom section of light fixture the LED light module took a crap but the zapper still works
                                          by sam_sam_sam
                                          So I got the bright idea to remove the LED light module from the fixture and put it on top of another enclosure and keep using the zapper

                                          The removal of light module was a successful and now I just have to cut a hole in the enclosure and put a power cord that has an on and off switch on it

                                          You are lucky to get about two years of service out of one before the LED module starts flicking and just stops working because it is mounted on an aluminum plate and these are hard to solder on it and it is not worth messing around with them and especially this one because it has line...

                                          This is a cap on a motherboard from 1994. β€œArk” is the only brand I know of that has an A inside a rectangle, but I wanted to run it by you guys and get any thoughts on quality.

                                          Thanks in advance....

                                          SFX PSU - Need High Current on 3.3V & 5V Rails?
                                          by DrewPhillips
                                          I have an older system which was built in the Windows 7 era and which has developed, I suspect, a power supply problem. The system had the same problem, random crashes, a couple of years ago, which I subsequently remedied with a new power supply.

                                          The power supply which came with the machine is a no-name "Safe Power PE-300". It is SFX form factor and claims a high current capacity: +3.3V @ 22A and 5V @30A (the +12V rail claims a meager 16A). Problem is that SFX supplies (or even ATX supplies for that matter) having high current ratings on the 3.3V and 5V rails seem to be...
