Best Graphics Card for Dell Optiplex 780

Updated on May 2, 2023

25 years ago, DELL introduced the Optiplex Desktop. As a member of the Dell Optiplex 780 family, you have the option of selecting from four different form factors: Mini Tower, Short-Form Factor, Desk Top, or the Ultra Small-Form Factor (USF) (U.S.F.F).

The SFF has two expansion card slots that can be accessed from the rear. The Graphics Card expansion slot is compatible with low-profile cards. A 235-watt power supply is available. You can choose between Intel Core-2 Quad (3.00GHz) or Intel Core-2 Duo (2.66 GHz) CPUs for the SFF (3.33 Ghz as well as 3.16 GHz, 3.0 GHz). There is only one PCle X 16 slot in this device.

Graphics Card Attributes for Compatibility with the Dell Optiplex-780 SFF

The following characteristics of the Optiplex 780 SFF influence the selection of a graphics card:

Slots. The Optiplex 780 SFF has a dedicated PCle slot for the graphics card. There are no high-profile cards that will fit in the Short Form Factor enclosure. Due to the condensed layout, only cards with heatsink cooling can be used.
A source of power. In regular use, the Optilex 780 SFF’s power supply is 235W. Despite the need to distribute this power and account for power supply instability, the various components in the system must each receive some. About 25 watts of electricity from the motherboard is all that is required for the graphics card to function.
System for dissipating heat. In order to accommodate graphics cards that require a lot of cooling, the PCle slot has a limited amount of room. Having a fan would occupy a large amount of room. Moving parts don’t cause wear and tear on Heat-Sink Cards.
Casing. Only cards with a low profile can fit in the Short Form Factor without reorganising the unit’s architecture.

The Intended Application

Graphic Cards have long been associated with 3D gaming and other applications that require 3D visuals. There are more and more uses for graphics cards, and their capabilities are getting better and better. A portion of the processing burden is being relieved from the central processing unit by graphics cards.

There are currently a variety of uses for graphics cards. The ability to stream HD and Ultra HD video at high quality and at high speeds; the ability to edit graphics; and the ability to work together on projects that need a large amount of processing power.

The intended use of a Graphic Card will influence the amount of money spent on it. Because the Optiplex 780 SFF was designed to be as small as possible, we can only go so far with its hardware architecture before it becomes unusable. A complete system update is recommended for increased functionality that necessitates a high level of visual computing power.

Determining Features on Graphics Processing Units (GPUs)

The memory of the video camera. The graphics card’s RAM. Additional functions can be supported with more RAM. RAM can affect how realistic animations appear in games. Texture and depth are improved with more RAM.
The sort of monitor that can be used with this unit. VGA displays can only be used with older graphics cards. Both DVI and HDMI connectors can be used with newer models.
It’s the frame rate. In the game industry, this attribute is critical. The FPS (Frames Per Second) is a measure of how smooth graphics seem on the screen, particularly when moving. The total user experience in visual graphics is determined by the frame rate.

Video Cards compatible with the Optilex-780 SFF in the Market

The Optilex 780 SFF’s attributes allow us to look at some of the compatible graphics cards.

SFF-friendly graphics cards have a low profile and are compatible with the PCle X 16 slot.

There are numerous of these graphics cards that don’t meet today’s high-resolution needs, according to their specifications. At a minimum, HDMI video output is required for high-quality video.

Graphic cards from the ASUS Chipset 6450 and 5450 series appear to be the most promising.


A tiny AMD graphics card from ASUS, the Radeon HD 5450, is available. The heat is dissipated through a heat sink, making it extremely quiet and easy to use in a home theatre.

It uses a Radeon Hm cpu with a clock speed of 650 MHz to run. For video output, it can connect to DVI-I and HDMI ports. It requires up to 75W of power, which is supplied by the motherboard without the need for additional power.


The ASUS RADEON HD 6450 has a strong heat sink cooling system that is also quite quiet. This device is powered by an AMD RADEON processor. DDR3/GDDR5 memory in the form of 1 GB is onboard. HDMI, DVI and VGA are all supported as outputs. However, when it is required, it only consumes 27 watts of power. Because of its low profile, the Optilex 780 SFF can accept it.

The AMD-RADEON 6450 Card is an excellent choice for use with this card for the majority of PC-based games and visual editing chores. Considering the price tag on the card, it delivers good 2D and 3D visuals for the most part.


There are several inherent limitations in the DELL OPTIPLEX-780 SFF’s architecture that must be taken into consideration while looking for the finest graphics card to go inside. This also restricts the SFF’s options in terms of graphics and video.

When it comes to performance and quiet operation, the AMD RADEON HD 6450 is hard to beat with its passive cooling technology.

RADEON-HD 6450 users claim that the graphics card is able to maintain acceptable frame rates in various games, and its ability to present 2D and 3D visual effects decently in PC games and Adobe apps makes it helpful.
