- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE10328:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE10328:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

Give a spare desktop PSU a second life as a capable multi-rail bench supply. This board takes a 20 or 24-pin ATX connector and breaks every pin out to labelled screw terminals, so you can tap 3.3 V, 5 V, 12 V and -12 V for your projects without cutting a single wire.

Getting power out of an ATX supply usually means bridging PS\_ON to ground with a paperclip and splicing leads. Here a latching push button turns the supply on and off. Eight indicator LEDs show which rails are live, along with standby and PWR\_OK status, so you can see at a glance that the supply is healthy.

Setup takes a minute:

- Plug in the PSU's 20 or 24-pin connector, lining up pin 1 with the marked side (left). The wrong orientation will short the supply
- Wire your load to the labelled screw terminals
- Press the latching switch to turn the PSU on, then check the rail LEDs
 
### Features

- Get every ATX rail without modifying your PSU: a standard 24-pin socket accepts 20, 20+4 and 24-pin plugs
- Power on and off with one press, thanks to the latching PS\_ON switch
- Check each rail at a glance with independent indicator LEDs, including PWR\_OK (blinking indicates a fault)
- Wire up quickly and securely with two rows of labelled screw terminals
- Works with ATX and STX power supplies
- Mount it on a bench or in an enclosure using the four mounting holes
 
### Specifications

 | Property | Specification |
|---|---|
| Input connector | 24-pin ATX (accepts 20, 20+4 and 24-pin) |
| Compatible supplies | ATX, STX |
| Rails broken out | +3.3 V, +5 V, +12 V, -12 V, +5 VSB |
| Signals broken out | PS\_ON, PWR\_OK |
| Output terminals | 24 screw terminals (2 rows of 12) |
| Indicators | 8 LEDs: +3.3 V, +5 V (x2), +5 VSB, +12 V, PWR\_OK, PS\_ON, -12 V |
| Power control | Latching push-button switch (PS\_ON) |
| Mounting holes | 4x Ø2.5 mm (approx. 63.8 x 52.8 mm spacing) |
| PCB dimensions | 70 x 58.5 mm |

### Notes

- +5 VSB is always live while the PSU is connected to mains power
- Some supplies don't output -5 V or -12 V (STX supplies output neither)
- On some ITX/STX supplies the PWR\_OK logic is reversed, so the LED is on when the supply is off
