AI Verdict
This is a plug-and-play life support system for aging office PCs that need multiple monitors or basic 1080p esports capabilities without a power supply upgrade.
This card is strictly a utility upgrade for aging prebuilts or basic office machines lacking display outputs. It lacks the horsepower for modern gaming, but the 50W power draw makes it a safe drop-in for weak proprietary power supplies.
If your power supply has a 6-pin PCIe cable, look for a GPU with 8GB of GDDR6 VRAM and a higher TDP.

Chance this product isn't for you
Pros
- Draws all 50W of power directly from the PCIe slot, requiring no extra PSU cables
- Fits easily into cramped cases front-to-back thanks to its short 180mm length
- Includes HDMI, DisplayPort, and DVI-D for native triple-monitor productivity setups
- The 9cm single fan stays quieter than standard Dell or HP case fans under load
- Handles 4K video decoding smoothly for home theater PC (HTPC) builds
Cons
- Takes up two PCIe slots in width, blocking adjacent expansion cards
- Struggles to power passive HDMI-to-VGA adapters, causing black screens during gameplay
- Multiple user reports of the card dying or artifacting within the first 60 to 90 days
- Uses the older PCIe 3.0 interface and Polaris architecture from 2017
Dimension Scores
Struggles with anything beyond 2017-era esports titles and 2D indie games.
The 50W TDP is incredibly easy to cool, and the 9cm fan stays quieter than standard case fans.
Pulls a maximum of 50W entirely through the motherboard slot, requiring no external cables.
4GB of older GDDR5 is barely enough for 1080p textures today, but perfectly adequate for multi-monitor desktop use.
Best For
- Reviving old Dell Optiplex or HP prebuilts with weak 250W-300W power supplies
- Adding three distinct monitor outputs to a basic home office workstation
- Playing lightweight esports titles like League of Legends or Valorant at 1080p
Not Recommended For
- Playing modern AAA games like Cyberpunk or Starfield even on the lowest settings
- Ultra-slim SFF cases that strictly require a half-height/low-profile bracket
- Motherboards where the adjacent PCIe slot is needed for a Wi-Fi or capture card
Watch Out For
- The cooler is 40mm thick—it will block the PCIe slot directly below it on your motherboard.
- Passive HDMI-to-VGA adapters often drop the signal under load because the card's HDMI port cannot supply enough power; you need an active adapter.
- Quality control is a gamble; multiple buyers reported the card failing or artifacting within the first 60 days.
- The ITX label only refers to the 180mm length; it is still a full-height card and will not fit in Small Form Factor (SFF) cases requiring half-height brackets.

What Buyers Say
This ITX card occupies two full PCIe slots in width, blocking expansion on cramped micro-ATX motherboards. People primarily purchase this card as a simple life-support upgrade for aging office PCs like Dell Precisions and Optiplexes. The 50W motherboard power draw makes it a painless drop-in for proprietary systems lacking PCIe cables. It handles dual or triple monitors flawlessly for productivity, but gaming expectations must be kept in check. Long-term reliability is questionable, with a noticeable cluster of users reporting premature deaths or artifacting within 60 to 90 days.
“bought this just to get two monitors working on my old dell tower. it does the job fine but dont expect to play anything newer than fallout 4 on it without it stuttering like crazy.”
Common Praise
- Runs entirely off motherboard power without needing a PSU upgrade
- Instantly recognized by Windows 10/11 for an easy driver installation
- The 9cm fan is practically silent during regular desktop use
- Handles 1080p 60fps in older titles like Skyrim and CS:GO easily
Common Complaints
- Died completely or started artifacting after 60 to 90 days of use
- The dual-slot cooler blocks the second PCIe slot on micro-ATX boards
- Screen randomly blacks out when using cheap HDMI-to-VGA adapters
- Stutters heavily in modern AAA games even at 720p resolution
Ownership Tips
- The card's HDMI port output can be finicky with older passive adapters
- AMD's Adrenalin software works fine, but the auto-overclocking features cause instability
- Dust buildup on the single fan is minimal even after months of daily use
Frequently Asked Questions
Does this require an extra power cable from my power supply?
No. It draws all its required 50W directly from the motherboard's PCIe slot.
Will this fit in a Dell Optiplex or HP EliteDesk?
It fits in standard mini-tower (MT) models. It is too tall for Small Form Factor (SFF) cases that require half-height brackets.
Can I run three monitors at once?
Yes. You can use the HDMI, DisplayPort, and DVI-D ports simultaneously for a triple-monitor desktop.
Is this good enough for Fortnite or Valorant?
Yes. It handles lightweight esports games at 1080p on low to medium settings at around 60fps.
Why does my screen go black when gaming with a VGA adapter?
The card's HDMI port struggles to supply enough power to passive VGA adapters under heavy load. Use a direct digital cable or an active adapter.
Buying Guide
You are buying a display adapter with a little extra horsepower, not a modern gaming GPU. This card's main selling point is that it doesn't need a power cable, making it perfect for upgrading old office PCs. Do not buy this expecting to play the latest releases. Check your PC case before buying—while it is short, it is still a full-height, double-thick card that will not fit in ultra-slim desktop cases.
50W TDP (No Power Cable)
Think of it like a USB flash drive; it gets all the electricity it needs directly from the slot you plug it into, saving you from replacing your computer's power supply.
4GB GDDR5 VRAM
This is the card's short-term memory. 4GB is plenty for running multiple web browsers and YouTube videos, but too small for the high-resolution textures in modern video games.
ITX Form Factor (180mm length)
It is short enough from front to back to fit in cramped cases, much like parking a compact car in a tight garage.
Alternatives
If you have a slim PC case, search for a 'low profile GPU' with a half-height bracket. If you have a power supply with PCIe cables, look for a card with an architecture from the last three years and at least 8GB of GDDR6 VRAM.
