    Antec Bp450PS PSU - Does it have all the necessary protections ?

    Hello Experts ,

    I am looking out for a good Passive/No PFC power supply to use it with a non-sinewave UPS, and came across Antec Bp450p

    This is going to be used in an office PC , so it won't be stressed much

    Since this is a budget PSU , Can you please check whether this Power supply "actually" has all the necessary protections ?

    In case of PSU failure, is it going to kill other components of the PC ?

    Is it safe to use ? Does it have the necessary protections to prevent the harm to other components of PC ?

    You can find the pics in this review

    Thank you very very much

    I hope i'll receive a reply

    What is your definition of "all the necessary protections"?

    It is a fairly cheap CWT built unit, yes it is safe to use, but with the Capxon, Aishi, and Teapo (Teapo isn't too bad but the others are) caps it has don't expect more than 3-5 years at most out of it unless you do a recap. It looks like the Antec Bp450PS is an "international" unit and the equivalent FSP built VP450 we get in the US is a better built unit (though still let down by Capxons on the secondary).

    Is there a reason you need non-PFC? Most decent PSUs made in the last several years are APFC, so that limits you to "budget"/entry-level PSUs that tend to have cheap components (especially caps).

      its because of the above. i heard apfc psus dont like the square ac waveforms given out by some ups. some apfc psus will trip and shut down if close to the max rated load. so i guess a ppfc or no-pfc psu will tolerate the square sinewaves from such a ups better without high load issus.

        True, didn't even think of that, I run an APFC PSU (currently a PC Power & Cooling Silencer 910W) with a non-sinewave UPS (Opti-UPS E1000C), and have never had issues with it (nor did I have issues with the Antec True-Power Quattro 850W in my old system on the same UPS), but it isn't loaded anywhere near its rating (likely 500W-600W max under full load with my I7-4790 and Radeon R9-380), the 910W PSU is definitely overkill on this system, but I got too good of a deal on it to pass up (bought it when they were being discontinued, I believe I paid around $60 after discounts and rebates, and a decent 500W PSU sells for that).

          The 4 basic protections OVP , OCP , OPP , SCP for all the rails . Does it have all of the above ?

          yes , i don't expect it to last more than 3 years but when it dies i don't want it to kill my mobo/cpu/ram/sdd/dvd

          Don't want something like this

          We have Antec vp450p here which is APFC

          Yes where i live there are bad power problems , so a UPS is necessary and all of them are modified sinewave UPS that don't work well with APFC ..
          Some do work but then it becomes a question of taking risk , buying and hoping that it will work with the specific UPS , dealing with returning/selling hassle and then finding another .. or it may work with modified sinewave ups but may require buying a larger VA UPS . I have an APC 600 VA ..

          If the antec one is safe and don't pose any danger to other PC components it is much better and cheaper to just buy this for an office PC at the cost of slightly lower efficiency and shorter lifespan

          Thank you

            If the computer is that important, why having a cheap modified sine UPS to start with? After all you get what you pay for. Doesn't make sense to me to fiddle around too much with the PSU lifespan and be worried if the PSU kills the main board.
            I have quite a few UPS's all kinds of sizes, towers, rack mounts, small to big. Some are true sine, others are modified sine. I have to see yet a PSU getting killed from either UPS on a decent computer PSU (all APFC), off course there is other gear using the UPS too. I had only one UPS's sacrifice itself due to a direct lightning stike on a 350ft tower, but then the generator panel was toast too. Usually these get hit at least once a year on any of these towers, only one UPS failure, no damaged equipment over a 7 year period.
            So the Antec should be fine. You are feeding it with 220V anyway.
            On some PSU's you can take the PFC out and just run it on straight AC.

              Yes weather they actually work or not would likely require testing, and since this PSU isn't sold in the US I've never seen/used one. Though I doubt Antec would sell a PSU without such protections in working order, their basic units may be exactly that, basic, and generally don't have the best caps, but they are all solidly built units, that can actually do their rating and likely won't damage your components in event of a failure (though there is no guarantee, even a the best PSU can fry a motherboard if you are unlucky, but it is much less likely to do so than some cheap off-brand piece of junk that lacks all protection and can't output half its rated watts).

                ^this^. TS, if u must open up the psu that u bought for whatever reason, u might as well just get a well-built apfc psu but hotwire the primary side to bypass the apfc circuitry and turn the apfc psu into a non-pfc psu. that would actually widen your choices in selecting an affordable psu for your use. there are well-built psus out there but with crap caps.

                  thanks a lot everyone for replying..
                  then i'll buy an APFC Model

                  Thanks

                    by GnatGoSplat
                    Antec BP500U PSU fried in my wife's gaming PC. I smelled something unpleasant last night, so I had a hunch something might be amiss. Woke up this morning to a popped breaker and immediately assumed the APFC cap must have blown. I last fixed it sometime in 2011, there's a thread about it here someplace. APFC and secondary caps that time. Replaced them with Panasonic caps. 10+yrs is probably a good run. It's been running 24/7 the last 3yrs, eth mining with a 1070ti and AFK fishing in Black Desert Online, lol.

                    Anyway, cracked it open this morning, expecting it to just be the APFC cap...

                    Hi everyone, hope all of You are having a good day. I have a Question from protections in some of this PSU brands and models: Dell Optiplex series 745 to 380 to 390 to 7040 - HP EliteDesk series - And some new Lenovo minitower series. I don't know how to find info. about their protections [ OVP (Over voltage protection) - OCP (Over Current Portection) - OPP (Over power protection) - SCP (Short Circuit Protection) - short - OTP (Over temperature Protection)], some Internet's friend told me that Delta company buids to this brands, but not lists that information if that the client request that protections...

                    by sirpsychol
                    While recaping Antec Earthwatts EA-380 I've broke one side of unknown smd element, it have no print, it's flatter and darker than smd capacitors on this board, shaped more like resistor but it's not resistor ofc. Unfortunetly the printed description was under it and element was glued to the board so I cant read/tell the letter before element number too. Have anyone any idea what it is? Maybe is there any diagram of this PSU?

                    Picking caps for Antec SU-380
                    by ajdrenter
                    In my search for a proper 5v heavy ATX power supply, I selected an old Antec SU-380 that I've had in storage for a long time. Opening the power supply reveals a couple bulged capacitors. I removed all the caps and made a map for myself. I found the datasheet for the PCE TUR series in this thread:
                    https://www.badcaps.net/forum/showthread.php?t=14159
                    It says these are general purpose, so I assume I can replace them with any general purpose capacitors, but I don't really know anything about power supply circuits or reading capacitor datasheets. Despite this, I've been shopping for replacements:...
