POWER MAC CUBE G4 MOD
POWER MAC CUBE G4 UPGRADE

The G4 Cube already has a tray for a 80mm slim fan. All of these processor upgrades require adding a fan.

Some of the companies that made this processors upgrades were: PowerLogix, Sonnet, GigaDesign and NewerTech. They must be specifically designed for the G4 Cube.

Processor: A couple of companies made faster processors (also known as "accelerators") for the G4 Cube.

POWER MAC CUBE G4 UPGRADE

You could upgrade to a 40 GB (5400 RPM) or 60 GB (7200 RPM) even a 120 GB hard drive, but drives larger than 128 GB are not supported. Hard Drive: The PowerMac Cube came standard with a 20 GB (5400 RPM) hard drive.The maximum amount of ram you can add is 1.5 GB. 64 MB, 128 MB, and 256 MB configurations were available later. Memory: The PowerMac Cube originally shipped with 64 MB of RAM.You can cost-effectively upgrade a number of components in the PowerMac Cube. It was replaced by the Mac Mini in 2005, 5 years later.

POWER MAC CUBE G4 MOD

This is a popular mod to cool overheating Cubes. You can buy a fan and connect it to the 12V 2-pin connector, and find somewhere to put it in the Cube. It has an internal fan hookup, but isn't used by Apple. The Cube is also a popular candidate for MacQuariums. After one year of production, Apple put the Cube "On Ice." Thanks to its passive cooling, the Cube was virtually silent-except for the original 5400 RPM hard drive. While this clock rate is significantly lower than the competing intel chipsets of the time (1.3 Ghz Pentium 4 at the high end), the Cube's G4 featured an AltiVec module and a more efficient architecture (RISC vs CISC), making the PowerPC chip faster than an Intel CPU running at the same clock speed. The Cube boasted a 450MHz or 500Mhz G4 CPU, wich was faster than entry-level PowerMac G4s of the same year. However, overheated CPUs are a rare problem with stock hardware, a fan is a necessary addition with any third party CPU-upgrades. This was seen as a mistake on Apple's part, because G4 processors run very hot. Unlike most other computers, the Cube used passive cooling, with no fans. Released in 2000 at a cost of $1599, the cube was considered too expensive compared to full-size PowerMac G4s. After resetting the PMU, be sure to reset the time, date, and other system parameter settings.The infamous Powermac G4 Cube, Apple's original failed attempt at a compact G4-based Macintosh. Important: This procedure resets the computer's PRAM.

Use Apple Hardware Test to check the computer.

If the computer does not turn on, there is something else wrong with the computer. If the computer turns on, go to the next step.

Wait ten seconds before connecting the power (adapter) and turning on the computer.

S1 is located on the logic board, under the video card, near the edge of the logic board at the end opposite the video ports. Warning: Do not press the PMU reset switch a second time because it could affect the PMU chip. Make sure the connector J4 on the video riser card and the video riser card is installed in its connector, then proceed to step 3.

Press the PMU reset switch (S1) once on the logic board.

If the battery is good, go to the next step. If the battery does not have the minimum voltage, replace it, wait ten seconds, and then reset the PMU (refer to the next step). The battery should read 3.3 to 3.7 volts.

Disconnect the power adapter from the computer and check the battery in the battery holder.

When you have a computer that fails to power up, follow this procedure before replacing any modules: Many system problems can be resolved by resetting the PMU chip. If the PMU crashes and is not reset, the battery life goes from about Ave years to about two days. The PMU is very sensitive and touching the circuitry on the logic board can cause the PMU to crash. Important: Be very careful when handling the logic board.

manage system resets from various commands.

tell the computer to turn on, turn off, sleep, wake, idle, etc.

The PMU (Power Management Unit) is a microcontroller chip that controls all power functions for this computer.
