Seems like a bargain with current PSU prices & stock availability, plus the benefit of being a true local store with full warranty. They tend to post pretty quickly in my experience as well. Also available at PCCG if that's your fancy.

SFX PSUs are pretty hot property at the moment. I was looking for something ~600W but they are still too pricey, so I settled on this little badboy for my pending Mini-ITX build (in a CM NR200 - which actually can fit an ATX PSU, but probably not with a 240mm radiator as well).

I can get by with 450W for my AMD 2300X, RX570, Corsair H105 cooler and other peripherals & fans. Should even have wiggle wattage for overclocking.

  you would be mad to run an ATX PSU in an NR200. limits significantly what you can do with the case.

  I recently rebuilt a 6700K system with a Zotac PGF 1070 (big boi card) into an NR200P, with an SF450 - works well. Good price at $109 for a decent quality 80+ Gold SFX PSU.

    Ryzen 7 5700G would work with white NR200 - so sexy

      Your username - how i would describe cramming an ATX PSU into an NR200.

      5700G would be good - but so would a 5600X or a 5800X and a dedicated GPU - if you run the NR200 in ordinary orientation (no riser cable), you can fit some pretty big 3-slot cards in there.

    I'm currently using an ATX (non modular) PSU in my nr200 with ryzen 5600x and a 2.7 slot 1660ti, by removing the PSU caddy and using the Velcro straps supplied in addition to a few I added which sits fairly securely, while awaiting a price drop on the SF600.
    The only limitation is I'm unable to install a 120mm fan at the top front and my 240mm rad won't fit. All of this runs well (although a bit toasty with CPU temps hitting 80 at times) with no thermal throttling. You could easily install a beefier air cooler whike using an ATX PSU for better temps.

      80 degrees on a 5600X is really bad, regardless whether it is throttling.

      unless you are planning on moving to a 3070 or higher tier GPU, the SF600 is really unnecessary for that build. go for the SF450!

        Future upgrades being considered when the GPU prices "normalise". 80 degrees on a Ryzen short term, isn't alarming or anything to worry about (how often are you actually running Prime 95 blend anyway?) when you have a TJMax of 95.

          @th3brad: oh i thought you meant hit 80 degrees during normal workloads. if thats 80 degrees during prime95 only then while its still not ideal, not quite so concerning.

          just because Ryzen chips have a high TJMax doesn't mean you should be running them that hot. i try to keep my ryzen chips under 70 degrees (actually pretty easy with decent cooling).

            @xyron: My previous system (r5 2600) barely hit 55 under water at 4Ghz.

            What do you reckon Xyron? Eventually going 3060ti (or equivalent). Do you reckon the 450W PSU would be enough? I've never bought a "decent" new PSU and I am an ozbargainer after all.

              @th3brad: i say 450w more than enough for a 3060ti (thats what i have in my main system at the moment, got one last year before the prices spiked) but if you wanted to go 3070 or higher, you may want a bit more headroom than that.

                @xyron: Legend. Thank you fellow tightarse. Just ordered it. My temps will now improve now I can fit my rad.

                  @th3brad: Corsair really could sell this PSU as a 500 or 550w given its ability to maintain 80+ gold rating even when drawing that level of power. https://www.tomshardware.com/reviews/corsair-sf450-power-sup…

                  it's a genuinely great choice for the money, and tbh probably would run a 3070 or 3070ti without much issue (i probably wouldnt run a 3080 on it, though).

                    @xyron: UPDATE: Just received the PSU today. Installed it and my 240mm rad. Temps max out at 51C in prime95 :))) Even cooler than my 2600 did in the older, much larger case.

    Eh, I've done worse before. Heck, a case isn't even necessary, you can plug everything in and power up with a screwdriver on the pins. Aesthetics be damned if it works 👹

    I just didn't want to tear up my current build for the PSU in case things go pear shaped (likely).

  I am running RX 5700 with this and so far so good. Do you guys think running this with Rx 6700XT will be ok too?

  • 

    xyron on 23/06/2021 - 09:47

    yes, the 6700XT is actually a more efficient GPU than the old RDNA (gen 1) cards so it shouldn't be a problem!

  I think this is the one I have, pretty happy with it. Some people complain of coil whine on the 650 model.

  Great for ITX builds, I have 6 x3.5" HDDs 2x 2.5" SSD and 2x 2.5" HDD and it runs the lot.

  The Coolermaster V SFX 550W Gold is on sale at umart right now for the same price (free pickup) seems to be a decent unit as well based on the psu tier list

    Also seems to be modular, nice find.
