DELL design has always been relatively calm, especially to the business computers, OpitPlex 745 using a tower case, the case is one of the largest volume, stocky shape, and in accordance with the EU's RoHS regulations, all use of non-lead production, plastic parts also had no halogenated flame retardants, and it did not use PBB, PBDE materials.
Because the machine uses the BTX case design, so using the front panel cutouts to help improve the effect of case fan ventilation. Front are two USB interfaces and one audio interface. May be considered commercial use so doesn't have a card reader, drives are ordinary DVD drive.
But says from the appearance, DELL OptiPlex 745 tower case is not a small head, long 43.18cm, width 18.7cm, height 41.14cm, but fortunately DELL offer a total of four sizes of cases consumer choice, in addition to ultra-compact case cannot install a separate graphics card, the rest of the configuration is almost no different, users can freely according to their actual needs customization.
Side without any cooling hole, this is a big advantage in BTX case structure, the integration of the aluminum alloy panel design, coupled with DELL LOGO, on the one hand, very beautiful, on the other hand, the protection of the case is also enhanced.
On case panel, this is a humble small dot, that is DirectDetect fault diagnostic lights, through it can quickly understand the status of the disk activity status and network connections, this feature is particularly important for the internal IT administrator. When computer has problems, you can identify the cause of the fault at fastest speed and quickly resolve, minimize loss due to computer damage. And individual users can quickly view the fault number, then call the DELL customer service center for simple and effective fault advisory.
The case front panel is the grid of hollow out design, we can see the machine's fan, this is a feature of BTX case, pumped cold into the chassis from the front, and then through the radiator to send wind to various parts of the machine, have the effect of cooling. The cooling effect is better than conventional ATX structure design, lower noise and more environmentally friendly.
Using the structure of BTX, but look on the back of the interface and the difference is not too much with conventional case. Dell OptiPlex 745 uses the IntelQ965 chipset motherboard, with six USB interface, no PS2 mouse and keyboard interface, can only use the USB device. Graphics card uses the D - sub interface, support double output, and then was also presented a D - sub line.
From the exterior, DELL OptiPlex 745 design was a success, not only design feels very stable for business requirements, but also following users’ different requirement to custom case size, it also gives full internal consideration and provide a strong support and help for administrator's job.
DELL OpitPlex 745 using the BTX box structure design, for business users to provide reliable and low noise business desktop computer, but also design the function of free remove tool, then we will see what it is inside, exactly what are the special features.
DELL OptiPlex 745 uses the Intel Q965 core Micro ATX motherboard that supports Core 2 Duo processor, up to 1066MHz FSB, DDR2 533/667/800 Dual Channel, and has 8GB / s of bi-directional PCI Express bandwidth, supports PCIE x16 graphics interfaces also it integrates function has been simplified graphics core GMA 3000 IGP, but in OptiPlex 745 was replaced by ATI X1300Pro graphics card.
DELL OptiPlex 745 use HyperCool thermal management technology, to ensure the system run more stable, quiet, good heat dissipation. You can also see the bottom of the box with cable connect floppy drive, which is reserved for the convenience of later use floppy disk extension project.
The machine uses a PFC power supply, with ASF 2.0 power support, in line with the Energy Star standard, energy performance to the extreme, OptiPlex Energy Saver energy-saving technologies can be pre-set in the BIOS, the system will still for 15 minutes, then system enters a low power state, which is more stringent than the energy Star regulations 30 minutes, to further enhance the power management features. And coupled with the power factor correction, Core 2 Duo processor and BTX case design, make the OptiPlex 745 desktop up to 42% less power consumption than the previous OptiPlex generation, while also saving the earth's resources.
