    how does these compare to the corsair ones?

    who would buy a 400W ATX PSU?

      Plenty of systems would easily run on a 400w PSU and they are most efficient when you actually use a good percentage of its output.

      4-6 core system with SSD storage and intergrated graphics or low end dedicated no problems

      • ln28909 on 21/10/2020 - 16:43

        yeah if that was your use case, surely you'll build an itx case for space saving

          Not if you wanted to save money by not buying an itx motherboard and SFX PSU.

          Nope,

          my own office PC runs 24/7 on an Antec NeoEco 400W PSU. It's

          AMD 3700X on Asrock B450
          32G RAM
          SSD x 1
          HDD x 5
          AMD RX570 running 3 monitors and occasional gaming.

          100% stable. Max power use ever measured via a wall meter was low/mid-200s Watts maxed out.

          Sure, it's not the ultimate gaming rig but the point is that people get sucked into buying without really knowing the true power consumption.

          Me, I'd rather buy a good quality unit of appropriate size than chase marketing numbers UNLESS there's a real need for 750W etc.

          • ln28909 on 21/10/2020 - 17:11

            @freddofrog42: I mean if you're only pulling 200W from the wall , that's only like 190W to the system so pretty much you're graphics card is not being utilised much, as an RX 570 on its own can pull up to like 300W at max load

            https://www.anandtech.com/show/11278/amd-radeon-rx-580-rx-57….

            And running multiple monitors is actually not an intensive graphics task, my XPS 15 with 1050ti Max q run 2 4k 1 1440p monitors without problems

            If you were to fully utilise you're current system you'll easily exceed the limit since a 400W PSU can actually only transfer around 330-350W stable to your system and I'm not sure if it's a fallacy or not,but I think running your PSU at full load all the time is not a good idea

            • Skips on 21/10/2020 - 17:21
              +1

              @ln28909: That's not correct.

              RX 570 is 200w at max load and about 150w when gaming.

              Also any half-decent 400w PSU is rated to put out 400w to your system, not pull 400w from the wall (i.e power input from the wall will be higher).

              • ln28909 on 21/10/2020 - 17:23

                @Skips: Ah okay I see, always though its pulling from the wall

            • Trance N Dance on 21/10/2020 - 17:23

              @ln28909: Yes… a GPU with a max TDP of 150W will draw 300W…

              Depends on the PSU manufacturer, some quality PSUs will actually delivery what's written on its side (peak v sustained ratings).

              Running anything at full load all the time is never a good idea for longevity, doesn't mean you can't or shouldn't do it. If you have a quality PSU, you can run at 90%+ load for extended periods of time over a long time no problem. Just don't expect it to last much longer than the stated warranty period.

              • ln28909 on 21/10/2020 - 17:33

                @Trance N Dance: Idk man, RX 580 TDP is 185W, but my Sapphire Nitro + has 1 8 pin and 1 6 pin that's 300W of max power draw

                • Trance N Dance on 21/10/2020 - 18:50
                  +1

                  @ln28909: The power draw isn't reflective of how many pins it takes but rather the number of pins it takes is reflective of it's power draw.

                  Power draw dictates how many connectors are required (because of the specifications on pci-e power cables, max 150W per 8 pin pci-e connector), the reverse isn't true. Your RX580 requires two power lines because it's over 150W but under 300W.

                  • ln28909 on 21/10/2020 - 18:52

                    @Trance N Dance: Nah man pcie slot is 75W with 150W is plenty for its TDP, like the Striz top OC only has 1 8 pin, fairly sure the shappire can pulls 250W pretty easily

                    Same as 3080, TDP 320W, FE model and Tuf pulls around 350W but FTW3 pulls almost 450W, hence the extra 8 pin

                      @ln28909: Not everyone is running a RX580 overclocked (which would change the TDP). We started at whether a 400W PSU could handle a RX570 and we now somehow have ended up with overclocked RX580s.
                      The anandtech article you linked to even says total system draw for stock RX570 is 298W (with i7-4960X on X79), OC'ed is 330W.

                      • ln28909 on 21/10/2020 - 19:09

                        @Trance N Dance: Oh lol my bad should've read the articles, thought that was just the card by itself

            • Hiphopopotamus on 21/10/2020 - 17:24

              @ln28909: The RX 570 pulls ~170W when gaming.

              • ln28909 on 21/10/2020 - 17:28

                @Hiphopopotamus: Yeah I did think that news article was probably too old now to be accurate, even though the rx500s have terrible efficiency surely i wouldn't pull that much power

            • scottySK on 22/10/2020 - 06:58

              @ln28909: Your link actually proves that the Rx 570 doesn't get anywhere near 300W. That is the total system consumption shown in the graphs.

          • wetwork on 21/10/2020 - 17:20

            @freddofrog42: Yep agree, one of my kiddies PCs has a reasonable spec, although use a GTX770 GPU.
            Be quiet's site calculates 383W and I've just installed a qulaity 550W PSU, which is more than ample. Some big number PSUs do not actually provide the claimed Watts. I prefer single rail 12V, it just feels better.
            Some lower Watt PSU's will not have enough PCI-E connectors for the GPU I use here - it needs 2. More recent GPUs may use less power connectors.

              @wetwork: I think 2 8 pin are standard rn, but 3 8 pin for heavy overclock card

              Personally I'll always try to buy card with the most connectors

              • wetwork on 21/10/2020 - 17:52

                @ln28909: Yeah - the 2080/1070 etc have an 8 + 6 pin supply as far as I am aware (same as my aging 770). I believe these are cards for "mortals".
                The more hardline/latest cards I don't know about. Not part of my small world!

    • scottySK on 22/10/2020 - 06:56

      Pretty sure tech yes city ran a a 3950x and 2080ti on a 450W power supply and left it running benchmarks for 24 hours straight with no issue. 400W would be sufficient for any mid tier build

  • dealhunter52 on 21/10/2020 - 17:10

    I would pay little bit more and get something like this with Japanese caps and 5 years warranty.

  • MrScavenge on 21/10/2020 - 17:20

    I have had issues with shipping times when ordering from Umart previously. Pretty sure item was marked "in stock" when it was not so took 2+ weeks to ship. If your not in a hurry decent deal though.

    • [Deactivated] on 21/10/2020 - 19:30

      Just a really old and shit backend. Store cannot change order only main office can.

      Pick is slow as well, usually be a few hours but during covid 19 it taking 2-3 days while other places is pickup within hours. If you need any urgent best shop elsewhere.

    400W is ample, even for a mid-range gaming PC. I have a Core i5 and mid-range Geforce card, and my system rarely exceeds 200W power consumption under load. If you consider that most CPUs have a TDP of around 65W, and a card like a 1660 is another 120W, that's 185W for the 2 most power hungry components. Add another 10W for the motherboard and things like drives and so on, and I can't see how you could ever get anywhere near 400.
