PS4 & PS5 controller · Marius board

On 3-pin builds, choose your joystick modules — ALPS, JS13 Pro+ or RS13 v3 at no extra cost, or JT13 / Kalih Carbon for +$30. The 5-pin MIDAS build comes with Marius-designed Hall-effect modules instead. Ships with updated firmware, factory-calibrated, and bundled with the exclusive Marius Optimisation App: an in-house Windows utility that adjusts system settings to improve performance and reliability.

    Order & returns

    The terms, in plain sight

    Build time

    Builds take 4–6 weeks. That can be shorter or longer depending on the spec and what parts are on hand — PS4 and MIDAS builds are made to order and sit at the longer end. You’ll get a lead time with your confirmation.


    Deposit

    A 50% deposit is required to commence your build, with the remaining balance to be paid in full prior to shipment.


    Change of mind

    If you change your mind after the build has commenced, a 10% restocking fee of the total order value will be deducted from your deposit. If you change your mind after proof of dispatch (POD), a 20% restocking fee will be deducted from the total order value. In both cases, return shipping is at the customer's expense.


    Warranty

    All parts and labour are covered by a 12-month warranty from the date of shipment. The warranty does not cover:

    • Physical damage, including drops, liquid damage, or misuse
    • Modifications or repairs carried out by anyone other than Slightly Optimised
    • Normal wear and tear
    • Damage caused by use of third-party accessories or components

    Thumbstick drift

    Controllers fitted with ALPS potentiometer modules carry a 3-month warranty against drift, due to the mechanical nature of the component. Controllers fitted with Kalih Carbon, TMR, or Hall Effect modules carry the full 12-month drift warranty. For the modules offered in the builder:

    • ALPS — 3-month drift warranty
    • JS13 Pro+, RS13 v3 and JT13 (TMR) — 12-month drift warranty
    • Kalih Carbon — 12-month drift warranty
    • MIDAS Hall-effect modules — 12-month drift warranty

    Assessment

    Any controller returned under warranty will be inspected prior to assessment. Warranty claims found to be the result of the above exclusions will be declined, and a repair quote will be provided instead.

    FAQ

    Straight answers

    Will it work on my PlayStation?
    No. These are PC only. The Marius board replaces the controller's original electronics, so a console won't recognise it. It's built for PC players who want 8K polling and mouse-click inputs — if you need it to work on console, this isn't the right build.
    What do I lose compared to a stock controller?
    Gyro, the touchpad, rumble, the audio jack and Bluetooth — the board is wired-only and the battery is removed. That's the trade for the polling rate and the input work, and it's listed at the top of this page rather than buried in the small print.
    Which joystick modules should I pick?
    On 3-pin Marius builds, three are included in the base price: ALPS (the standard potentiometer module fitted to Sony first-party controllers), JS13 Pro+ (an FPS-proven TMR module) and RS13 v3 (the latest-revision Ginful TMR module). Two are a +$30 upgrade: JT13 (tension-adjustable TMR, based on the JS13 Pro+) and Kalih Carbon (an upgraded potentiometer module with longer service life and lower electrical noise than ALPS).

    The practical difference is drift: ALPS wears mechanically and carries a 3-month drift warranty, while the TMR modules and Kalih Carbon carry the full 12 months. One trade-off worth knowing before you pick: the JT13 takes no aftermarket thumbstick caps — neither the Edge-style nor the Leadjoy No.2 — because its tension-adjustment collar sits where the cap would go. If swappable caps matter more to you than adjustable tension, pick a different module. The 5-pin MIDAS build doesn't use this selector at all — it comes with Marius-designed Hall-effect modules as part of the build. Not sure which suits how you play? Ask us — it's a two-line answer, not a sales pitch.
    How do I pay, and when?
    A 50% deposit commences the build, and the balance is paid in full before it ships — we'll send you a link for the balance once your build is ready. Payment is through Stripe's secure checkout, in AUD — card, Apple Pay, Google Pay, or pay in instalments with Afterpay or Klarna. The full list is shown at checkout. Instalment plans apply to each payment separately: the deposit now, the balance when your build is ready. It isn't one plan spread across the whole build, and whether you're approved is between you and the provider. Need to arrange something different? Ask us before you order.
    How long does a build take?
    4–6 weeks as a rule, though it can be shorter or longer depending on the spec and what parts are on hand — PS4 and MIDAS builds are made to order and sit at the longer end. You'll get a lead time with your order confirmation.
    Do you ship outside Australia?
    Free express courier delivery is included Australia-wide. For anywhere else, get in touch and we'll sort shipping with you before you order.
    What's the Marius Optimisation App?
    An in-house Windows utility bundled with every build, which adjusts system settings to improve performance and reliability — the PC end of the same problem. It's separate from our wider PC optimisation suite, which is currently in private beta.
