    Your spare PSU Stash

    Given the number of PSUs that get recapped, repaired and shown off here, I'm sure a few of us must have a bit of a stash of them. Here's what I've collected thus far (and still am yet to sell off):



    From top to bottom (Left "Column"): Lite-on 300W, Codegen "550W" (more like 300W), NMB 430W

    Middle "Column" Enlight/Delta GPS-300AB, Antec SL-350 (recapped), Dell H305P-00 (in Solytech case)

    Right "Column" AOpen/FSP 200W SFX, In Win IP-S400CQ2-0



    Left to Right, Top "Row": Thermaltake XP550NP 430W, In Win IP-P600CQ3-2, Corsair VS450, Macron MPT-4012 (all Recapped)

    Bottom "Row": Sirtec/High Power 250W SFX, Delta DSP-280FB, Hipro D3057F3H, Cooler Power GX850, Dell H750P-00.

    This excludes the gutless wonders. I have a few which I'll blow up on the tester when I get around to it.

    Re: Your spare PSU Stash

    I don't have much of a spare pine, currently I have a gutless wonder raidmax 380 and a recapped/repaired Antec SP400 in my spare bin. I have a few other ATX PSUs lying around somewhere, possibly in an unused computer if I need to swipe one from somewhere.

    I still haven't figured out what's wrong with this antec truepower trio 650 and it's sitting half disassembled... I really should put it back together again while it's on the backburner...

        It's been recapped. I don't review stuff which I've repaired. I did put it on the tester, though, and it does the full 400W well and truly in spec.

            This thread rocks! Look at all those PSU's

            I have way too many...Either to have on hand, waiting to sell, or just laying around because I recapped it I also have a parts pile as you can see. I really need to get organized. This doesn't even count the ones I have at home

                Re: Your spare PSU Stash

                I decided to only keep units with active PFC, as many of the "old-school" designs (TL494, two primary push-pull switchers with a pair of 200/250V primary electrolytics) are not worth anything to me (other than parts).
                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.

                  I've got a couple of boxes of PSUs like that. Need go through and weed out the good ones and test them. The crappy ones I am keeping for spare parts and projects.

                      I have mostly junk. Just a few good worthwhile units. Namely, a MPT-301, a HiPro HP-P2507F3P tank in a RaidMax RX-380K case , Bestec ATX-1956D, a Morex MXA-235PTF1, and a LiteOn 250W unit (forgot model).

                      I also have a PowMax LP-6100D and a Task TK-930TX. Not sure if I should consider these as decent, though. The PowMax... well, it's a PowMax, need I say more. I wouldn't trust it even with a recap and a proper 5VSB circuit. The Task PSU is built by Sirtech, but it has very crappy regulation and oscillates BADLY with a 12V load. I think a Deer DR-250ATX that I found last year is better than both of these. At least I know I can trust it up to 250W and it will have good regulation.

                      Why?
                      There are so many excellent "oldschool" designs without PFC. Just because they lack PFC doesn't mean they are inferior. In fact, many of the better ones (think OEM Delta, HiPro, and Lite-ON) are simple, yet bullet-proof tanks, especially with good caps.
                      I think you are missing out.

                        APFC might be more efficient but the APFC circuits are also more stuff to go wrong...

                          So true. It seems that the booster coil is the most likely thing to fail in a APFC circuit. With proper placement, I like an old reliable design with PPFC

                            Here, on 230V, that's not an issue, as the coils don't get as hot.

                                    Maybe the caps are failing. Wasn't it you that said Sirtec PSU's have an insanely picky feedback loop?

                                      All energy conversions have losses. In this case, APFC is just an extra conversion. So I'm not entirely convinced that APFC is more efficient. I think it's just that newer designs are more efficeint (i.e. single-transistor forward is better than half-bridge, then 2-transistor forward better than single-transistor, and etc.)

                                      Maybe I don't read enough PSU reviews, but I think it would great if someone took an APFC PSU, measured it's efficiency, then removed the APFC and measured the efficiency again. Has this been done before? If yes, then I'd like to see that article.

                                      Might as well. If I ever come your way, I'll buy an entrance ticked .

                                      Yup, that's me. But I think c_hegger confirmed it once, too.

                                      The Task PSU had 1 bad Jenpo cap on the 3.3V rail. But I replaced it, and that wasn't what caused the oscillation problem. I didn't experiment too much with it, but I remember (from a while back) that it didn't like it if you added an extra cap on the 12V rail (it has spots for 2x 10 mm caps, but only one is used and is usually 1000 uF... the other was 100 uF - yes, just one hundred uF). And although it seemed to be only stable with the stock setup, even then the regulation was quite bad.

                                      No, actually the problem is that I am too slow and too lazy and never get things done on time, so I never get to post all of that stuff on BCN. I actually have the pictures already.
                                      ... unfortunately, yes, you have to hit me on the head for me to do anything right
                                      But I promise you I'll do it someday. I really want to as well.

                                        I haven't heard of it. But considering until recently most PSU reviews only went as far as to check voltages in the BIOS and sometimes with a multimeter too, I'd be surprised if anyone has done something that interesting.

                                        I'm sure someone here could give it a try, though.
