    Good PSU. I could be wrong but wasn't this psu updated in 2018. Main change PSU shortened by 40mm making it a regular ATX size. A big plus for case fitment

      The series was updated but size did not change for the 550W model as it was already small.

      Tiny upgrades to FETs and controllers for the 550W, but otherwise it's nearly identical.

    Personally I wouldn't be buying less than 750W PSU if I was building a system now the way GPU's are going

      An AMD 5600X CPU with Nvidia RTX 3080, 16 GB of DDR4, 1x NVMe SSD, 1x SATA SSD draws around 464 W load - link. So why do you need the extra 286W (50+%)? … bragging rights?

      • +2 votes

        The human eye can't see above 550w. You will be needing RGB if intending to overclock.

        Edit. If your peak power is approx 500 watts you probably want a 650w power supply depending on efficiency. Split rails could mean needing higher. Given a quality PSU lasts 10 years buying an extra 100w adds headroom for the future.

        •  

          I have been running 850w PSUs for the past few generations because I ran SLI and before that CrossFire. But half the time it added no value. Now Nvidia and AMD have mostly given up on multiple gfx cards for gaming.

          Sure you can SLI the RTX3090. But I suspect now even less games will be optimised for SLI, if any. As far as I can tell, the future for gaming is a single gfx card.

          And yeah, split rails needs some headroom. The linked site added another 50W for that reason, and 514 < 550. But as always it depends on your kit, and yeah 650W will definitely cover it. 750W is overkill for most people in the foreseeable future.

            @rinco: What cards did you sli lol

          • +1 vote

            @rinco: Except the recommended psu is 750w+ for most of the high end cards. PSU are most efficient at 50% utilisation and running it less hard means it'll likely last you a lot longer.

            So imo and experience work out however much watts you need and then double it. That's the psu you want.

            Generally it's not a lot extra and its worth it for reliability and peace of mind.

              @4foxache: While that rule of thumb made sense a decade or two ago, times have changed. The efficiency of any quality 80+ PSU like this one is around 2-3% from loads as low as 20% up to 100%. So sure you will save a few dollars a year when aiming for a nominal 50% load, assuming you are running your system flat out for 8+ hours a day. But it is unlikely anyone other than pro gamers and crypto miners are running their systems that hard. Even then it will take years to recoup the difference in buying a more expensive PSU.

              With regards to reliability this PSU has a MTBF of 100000 hours. Under load for 8 hours a day that's a mean time of 34+ years. I doubt doubling the wattage will significantly increase the life. Even so, I wouldn't want to pair a really old PSU with anything brand new. So for me peace of mind is knowing I didn't overspend, and replacing the PSU every 7 years or so.

              Sure it's worth having some margin but it is counter productive for it to be excessive.

              •  

                @rinco: Maybe it's just me but I don't like running anything at close to 100%. Yes a complete doubling is probably overkill but I think 30-40% over is a good margin to allow for upgrades and also managing peak power spikes which can often be quite a bit over standard draw. Over time these spikes can be psu killers

              •  

                @rinco: I bought a new Silverstone Strider gold 750w a few years ago when I was building a new PC. First power up and it fried every part except cpu and ram. Took it back under warranty, got a replacement and tested it on a spare PC, fried that too.

                From this I have learnt 2 things;
                - if it ain't broke, replacing it with a new one might kill it
                - never again Silverstone

                YMMV

      •  

        or you can pay extra $100 to get 850 series and be at piece …..

      •  

        you should have some margin because PSUs perform better when there's headroom than when they are at 100% capacity.

        nVidia recommends 750w for 3080.

    •  

      Unless everyone's building PCs with 3080's, I don't see the point

    Good price. Really like RMx series, decent PSU. 550W is enough for 3060ti and lower.

  • +2 votes

    Also great for a HTPC if you want silence/no spinning fans

  •  

    Is it just me or has pc components gone up in price recently? This is the sort of price I'd expect 2 or 3 years ago or am I just being unrealisitc?

    •  

      I think it is a combination of reduced production due to COVID and for the video cards it is also the crypto miners.

    •  

      there is a shortage of certain components used by a range of hardware (phones, consoles, GPUs, CPUs).

      PSUs are not scarce at the moment though.

    Would this be good for a 1660/Super, and then any xx70 card?

    • +2 votes

      Use this to run a 2060 super, so no problems. As commenters have said above, 550w will be sufficient for most graphics card (just not top end high power draw cards).

    •  

      Yep be plenty for a 1660 which isn't a power hungry card at all. In fact a quality 450W PSU would suffice for a 1660.
      I used to run a Ryzen 3600X with RTX 2070 and this exact same PSU, never broke a sweat was rock solid for over a year.

      It will run most single GPU machines out there in the mid to upper range, last gen right up to a RTX 2080 should be fine, this gen a RTX 3070 could start to stretch it if it's overclocked, even more so with a power hungry CPU and many drives, fans, lights etc. A more minimalistic build without an overclock would be OK.
      Any 3060Ti would be great (about the same performance as 2080 Super). A 3080 or 3090 are both far too power hungry for this though, you'd want 650 - 750W+ depending on the rest of the build.

      •  

        2080 and 3070 are near identical when it comes to power usage

  •  

    Apparently the 550x and 750x is vary in quality?
    I had the 550x and when the pc was off. There was a humming noise. The replacement did the same. Ended up with the 750x with the issue resolved

    •  

      have two RM550x's no issues like you describe
      also have one RM750x

        When your pc was off. Did you put your ear next to your psu

          no. why would you do that?

          but i guess i'll try it.
          is it just after you shut down? or anytime?

      I had a coolermaster PSU with that issue (turned off, but still plugged into mains), but replaced it with a Corsair 650x which is quiet. My head is very close to PSU. Can't hear anything.

    the zero rpm modes in these things is brilliant.
