KECES P8 Mono Linear Power Supply, 19/20 V, 8 A

The KECES P8 Mono is a linear single-output power supply that feeds an audio device with 19 or 20 volts and up to 8 amps from a toroidal transformer.

It targets the power-hungry candidates in your chain: network players, music servers, NAS drives or small power amps that a wall wart simply can't keep up with. Everything sits in a 4 mm thick aluminium housing that logs voltage and current draw on an OLED display.

Why the KECES P8 Mono?

Because a great many modern devices run on 19 or 20 volts – and those are exactly the ones that draw the most current in everyday use. The P8 Mono bundles all its power onto a single output rather than splitting it across two zones: up to 8 amps, purely analogue, without the high-frequency switching noise of a switch-mode supply. An additional USB-A output at 5 V / 1 A powers small digital accessories on the side.

What you get

Headroom. A power supply that isn't working at its limit sounds more relaxed: the background gets quieter, transients arrive cleaner, and nothing sags during powerful passages. The OLED display always shows you the voltage present and the current actually flowing – surprisingly revealing if you want to know whether the factory wall wart ever had enough to give.

Who is the P8 Mono for – and who isn't it for?

Straight talk: if your device runs on 19 or 20 volts and draws a decent amount of current, the P8 Mono is the right choice. If you want to power two devices at once, take the P8 Dual or the P9. And if you're only feeding a 12-volt switch, you're better off with the smaller P6 – 8 amps for 1 amp of demand is like a truck for the weekly shopping.

Our verdict

The P8 Mono is the specialist for the one hungry consumer: plenty of headroom, an honest display, a solid housing. Tell us at HD Zürisee in Wädenswil which device you want to power – we'll check voltage, current demand and connector type with you before anything gets ordered.

Frequently asked questions

Which devices does the P8 Mono suit?

Anything that runs on 19 or 20 volts and draws a noticeable current: network players, music servers, NAS drives, mini PCs or small power amps. With 8 amps, there's ample headroom. Check the voltage rating on your device's nameplate before ordering – we're happy to help.

What does the OLED display show?

The output voltage present and the current your device is currently drawing. That's more than a gimmick: you see immediately whether the set voltage is correct before you plug in the cable, and whether the included wall wart ever had enough headroom.

What does the USB output do?

It delivers 5 volts at 1 amp and powers small digital accessories on the side – a USB reclocker, a Bluetooth receiver or a dongle, say. It isn't enough for power-hungry hard drives; that's what the main output with its 8 amps is for.

Which DC cable do I need?

That depends on your device's barrel connector; 5.5/2.5 mm and 5.5/2.1 mm are common. KECES offers matching Premium and Valentina DC cables in both versions and several lengths. Tell us your device and we'll tell you the right combination.

Why buy the KECES P8 Mono at HD Zürisee?

Because a power supply has to match the device: voltage, current demand, connector type and polarity. We clarify that with you before anything is ordered, and our technician integrates it cleanly into your system. Call, write, or use WhatsApp – we're happy to advise.
