Power Supply Units
If you have a Power Supply problem, note the following:
Unlike AT PSU's, ATX units will not power up unless connected to the 20pin plug in the mainboard, or if connected to testing equipment.
- Ensure the voltage selector to the rear is set to UK standard 230V.
- Turn on the Power switch (if present) on rear of PSU.
- Some ATX PSU's require the Power LED to be connected to the mainboard. Connect this to the two pin M/B connector and then depress the PC case's power switch.
AMD approved PSU's
We offer six models that meet AMD's recommendations. These are based on the ability of a supply to provide appropriate power to the +5V DC and +3.3V DC power rails. The following have been evaluated and recommended by AMD's in-house testing centre:
| Apollo 300w & P4 ATX Psu |
| Apollo 420w & P4 ATX Psu |
| Apollo 525w & P4 ATX Psu |
| Powerman 300W P4 ATX Psu |
| Powerman 250W P4 ATX Psu |
| Eagle 350w P4 ATX Psu |
PSU's For Micro ATX Form Factor / Desktop Form Factor
We offer two choices both rated at 145w from Powerman.
These differ in size to the standard PS/2 Power unit:
Dimensions:
| For Minitower V500 Case / CS888DMX : 150 W x 112 D x 85mmH |
| For Desktop D500 Case : 124 W x 116 D x 85mm H |
| For Desktop HC-B01 112 W x 153 D x 85 H |
Micro ATX and ATX have different form factors:
| Micro ATX output voltage is +5V +12V -12V +3.3V |
| ATX output voltage is +3.3V +5 V +12V -5V -12V |
