DFI PS83-BL (i865PE) Mainboard
|
This is a typical budget board that realizes the chipset's minimal
functionality.
Accessories:
- Package of an effective design;
- Documentation: user manual in 5 languages;
- Cables: one Serial ATA (without power supply adapter), one ATA66/100/133
and FDD;
- Bracket with 2 USB ports;
- CD with:
- drivers;
- user guide in PDF;
- Adobe Acrobat Reader;
- Award WinFlash 1.54;
- RadarSync;
- McAfee VirusScan Online;
- Winbond Hardware Doctor.
The board's width causes some downsides in the PCB's layout:
the IDE connectors are behind the PCI slots, and the audio ones are in
front of them. A video card inserted may lock memory modules. Also, it can
be difficult to reach some jumpers when the board is already installed. Their
description is provided on the PCB.
The 3-phase switching voltage regulator incorporates 12 capacitors
of 1500 uF. There are also voltage regulators of the AGP bus (2 capacitors
of 1000 uF and several less capacious) and of the memory (2 of 1000 uF).
Integrated controllers:
- audio controller based on the chipset and C-Media CMI9739A
AC'97 codec; 5.1 audio system supported, front audio outputs and S/PDIF connectors
provided;
- network controller based on the Realtek RTL8101L chip supporting
10/100Base-T (Fast Ethernet).
+2.5 V supplied to the memory modules in the StandBy mode is indicated
with the red LED.
A connector for the second COM port wasn't integrated though the
space for it is left.
System monitoring is supported by Winbond W83627HF-AW chip. It controls:
- processor, AGP bus voltages, +3.3, +5 and +-12 V, VBAT and +5
V Standby
- rotation speed of 3 fans;
- temperatures of the processor (built-in sensor) and the board
(built-in sensor)
There are 2 connectors for regulated and 1 for unregulated connection
of fans.
Summary: memory slots - 4 DDR SDRAM; expansion slots - AGP/ 5 PCI; I/O
ports - 2 COM/ LPT/ 2 PS/2/ 8 USB 2.0; dimensions - 305x210 mm.

We used the BIOS of 31.03.03 as the latest available version.
This board can't boast of its functionality or overclocking capabilities,
but its speed is equal to most its competitors, and the price is promised
to be low.
