Corsair RM850X SHIFT ATX 3.0 & PCIe 5.0 Power Supply $159 + Delivery ($0 C&C) @ Scorptec

530

Needed to upgrade a RM550X (2018) and this was the best ATX 3.0 & PCIe 5.0 power supply corsair provided that came with 10 year warranty at a reasonable price.
Also has somewhat flexible cables unlike the old 2018 and 2021 RMX power supplies

Looking at the US reviews online it costs 20% more for the SHIFT Series but strangely over here in AUS we sell it for 20% less vs its standard 2021 RMX sibling.

Some spec info here:
850W, 80 PLUS Gold, Zero RPM Fan Mode, Fully Modular Micro-Fit Connectors, 140mm FDB Fan,
ATX 3.0 & PCIe 5.0 Compliant ( For those with new Geforce cards )
10 Year/s Warranty
Cybernetics A grade Noise Level Certification. Its quieter than the 2021 version.

    These are good; just before you buy make sure it’ll suit your case, with the connectors being on the side, you need to consider the orientation of how you’ll mount it for the fan and what side the connectors will come out.

    • Yeah i have an NZXT H400 Mid Tower Case with around 2cm of space its heaps for this.. from the youtube videos it fits with very little space on the side panels.. those cables bend good.

    • To add to that from their site:

      CASE COMPATIBILITY

      The PSU and cables will fit in any PC case that supports ATX PSU format and is at least 210mm wide. The PSU must also be accessible from the side when mounted in the case.

    • In the youtube video reviews when they removed the old power supply and replaced it with the RMX Shift it looked to have more space. I think it maybe either thinner vs standard ATX, recessed a little on the connector side or the rear mounting screw holes are shifted to make for a little more room.

    SHIFTY power supply

  • +1

    Would this be enough to power a 4090 system? With latest intel cpu?

    • +1

      Erm, you'd probably want atleast 1000W, 850W sounds like its slightly not enough overhead

      • +7

        Nvidia is recommending a 850W or higher. They made the card they know what their talking about.
        Seeing as this 850W is a Tier A High-end power supply. Top of the list in quality so it should be more then enough for a 4090 and able to handle any GPU transient spikes.

        • Cheers

          Anything else on special a 1000w unit even if its abit more…?

          • @MrTillets: well you get 150w more power if needed… tini bit less efficient VS the 850w according to reviews. Also its around 1.5cm longer in size.. Same with the 1200w version.. a tini bit less efficient and larger in size (length wise)

            • @vid_ghost: Cheers mate any link to the 1000w unit?

              • @MrTillets: the 1000w is $289 and the 1200w is $333 on Amazon.com.au so you would be paying $130 more then the 850w for an extra 150w of power… not very good value my as well get something else for that price if you must have 1000w. Maybe 80 Plus Platinum if you can find one on sale.

                Looks like Amazon price matched Scorptec for the 850w, 1000w & 1200w power supplies + added a little less delivery cost ($4 less) vs Scorptec on them.

      Yes this will work fine.

      Yes it will be fine unless you go absolutely nuts and try to overclock the 4090 to the absolute power limits

      • +1

        only a few cards like the ASUS strix will let you get to 600w..Not that it does anything for performance anyways

    • Yep, I have a C750 and no issues at stock speeds. Unless you overclock, the card won’t go much over 400W so 850W will be more than enough.

    • Take a look at the Silverstone Hela 1200R - its a platinum rated PSU (this is gold). It also comes with a 600W 12vhpwr cable.

  • +1

    The sleeved cables look useful. The old stiff cables that came with my rm850x (I think 2021?) are very difficult to work with for cable management

    • +1

      The RMX SHIFT does not come with sleeved cables. They are just a little more flexible and easier to work with.. They also don't have in-cable compositors like the 2018 and 2021 versions.

      You can see it in the advertising and in youtube reviews.

    Thanks OP! Got it for a future build.

    If I am correct black friday would have more deals for PC parts? Thinking of slowly picking up parts as and when on sale as no urgency at my end.

    • +7

      Bookmark these sale dates:

      Amazon Prime day - Tue, 10 Oct - Wed 11 Oct 2023
      Click Frenzy - Tue, 24 Oct – Thu, 26 Oct 2023
      Black Friday - Fri, 24 Nov 2023

      The Amazon one would be the best with the best deals.. SSD's, Ram, CPU's, Cases & PSU's will all be going cheap.
      Click Frenzy and Black Friday could have some deals but going by last years sales the good specials sell out quick and are hard to find.

      I plan to buy all my Xmas gifts during these sales. ( check ozbargain.com.au every hour during the sale dates. ) use your phone if you must.

      Thinking of slowly picking up parts as and when on sale as no urgency at my end.

      I've been doing this as well. The one downside is wondering if a part you've had sitting there for weeks was actually dead on arrival, because if so you'll probably have to deal with the manufacturer rather than the store at that point.

      • +1

        Yeah, that's a bit of worry for sure. Fingers crossed

    One concern I have with this PSU is 12VHPWR connector.

    It is limited to only deliver 300 watts according to TweakTown. So, that means even if you include 75W from PCIe x16 slot, you get a total of 375W for the GPU. Also, it's not using a native 12VHPWR connector on the PSU so those data control pins are likely not wired at all.

    • does this mean it is effectively worse than a regular 850w power supply like the rm850x 2021?

      I ordered this but expected I would be able to use it in the future so this sounds worrying

      • +1

        It is still better than 2021 in general since the 12VHPWR cable is included. So if we go by TweakTown, RTX4080 should be okay with that cable. RTX4090 "probably" is still doable the same way as RM850x 2021 (since sufficient PCIe 8 pin cables are provided - i.e. still need to support older and AMD GPUs) via the 4 to 12VHPWR adapter provided in the card. Maybe the included 12VHPWR cable could work if no other PCIe 8 pin cables are used (i.e. TweakTown is wrong).

        The current situation seems to be PSU makers want you to buy 1200 (and maybe 1000 as well) if you want to get the maximum out of 12VHPWR. Technically, the included cable is rated 600W. However, quite a number of competing PSUs (using 12VHPWR to 12VHPWR cable, instead of this 2 8 pins to 12VHPWR arrangement) recently reduced the actual power rating of their 850W PSUs' 12VHPWR to 450W (so even if you get one of those, 4090 is doable, but 4090 Ti is unsafe).

        Also, RM850X shift doesn't perform better in every aspect compared to the 2021 model. Ripple performance is inferior for example. Not sure whether that's partially due to removal of in cable capacitors.

    • The 12VHPWR is grounded and will allow 600w

      This is talked about in the youtube reviews as lots of people were commenting about it. Corsair states 300w on the box but it can do 600w. Very scummy upsell marketing to the 1000 & 1200w models if you ask me

      It also has 3 x 8 pin PCIe cables so you can use the adaptor dongle if you want for the 600w like you would with an old power supply

      A future RTX5090 600w will work fine.

      • +1

        Could you post the youTube videos / reviews? There are just so much conflicting information. Anyway, the way it does 12VHPWR still means those 4 control pins are unsupported. I get they are not mandatory and Corsair's setup might be more flexible if you don't need PCIe gen 5/12VHPWR.

        I only have 1 case that offers sufficient side clearance (3cm), but only just. Another case I have, I need to mount the PSU upside down (not ideal, air flow not quite right and cables now exposed on the wrong side). Having the cables on the side does make installation easier, but not all cases provide enough clearance.

        • 2cm is more then enough.. 3cm is only if you want to use every single connector that's on the thing :) "gets chunky"

  • Connectors on the side… but why? Still a good deal, though

  • Sale price ended… price jacked backed back up everywhere.
