Things you MUST KNOW before choosing your Best Graphic Card without External Power

When people choose graphics card, they mostly consider the memory bandwidth and the GPU clock speed. However, the best graphics card is one that consumes minimum power. Power consumption is a critical factor that you must consider while choosing a Graphics card.

The good thing about low power consuming graphics cards is that they are affordable too because they don’t need any external power supply. Following are the factors that you need to consider before choosing the right graphics card without external power:

Form factor

Form factor is very important as you need to make sure that you have enough space for the card. Graphics cards are available in single slot, dual slot, triple slot, and half-height forms. If the Graphics card is not compact enough, its fan shroud and heatsink will come in the way of any adjacent slot. So, it is very important that you look at the height, length and thickness of the card.

If you have a small PC case which has still some space for a full-height graphics card, you’ll need a sgraphics card that is air-cooled and is not more than 8 inches long.

Consider the power situation

Another factor to consider is the PSU cable routing. Most of the cards have power-pin connection ports present on the top of the card while some of them have the pin connector on the rear-facing edge of the graphics card. There are many compact cards that don’t require PSU power connection because they already pull enough watts from the PCle slots. In this post we are going to review all such graphics cards.

Refresh Rate

The refresh rate depends on the monitor. If the monitor’s refresh rate is in triple digits, then you have to select a powerful graphics card to meet the ends. However, if you have a monitor that features resolution of up to 1080p or 60 Hz, then you don’t need to invest in an expensive graphics card.

Frequently Asked Questions

Can a PCle x4 card fit in a x16 slot?

Yes, a PCLe card can fit into x16 slot but can’t fit in a smaller slot. For example, if you have PCle x16 card, it won’t fit in a x8 slot. Some PCle slots use open-ended sockets too that allow you to fit any types of cards.

Can I replace DDR2 graphics card with a DDR3 one?

Yes, you can replace them. The graphics cards are compatible with previous ones too and all you have to do is to get an expansion slot for the new graphics card.

Do I have to change my PSU for new graphics card?

If you have a PSU that is not compatible with your graphics card, then you’ll have to change it. For example, if your graphics card has a 400W PSU rating and your PSU delivers only 300W, then you’ll have to change it for a higher one. It is always a good idea to have a PSU of higher rating than the one recommended for the graphics card.

Conclusion

If you’re looking for excellent-performing graphics cards without external power, then you won’t be able to find any better options than the ones that are reviewed in this post. The graphics cards reviewed above are all low power consuming cards and they draw power from the PCle slot. The graphics cards are not expensive and deliver superb performance in games.

Our top picks are EVGA GeForce GT 740 2 GB Super Clocked GDDR55 and MSI GeForce GTX 750 Ti as they are best overall in terms of power consumption and gaming performance. These graphics cards are powerful and fast and deliver a smooth and stutter-free gaming performance.

    • Hi,
      Most of the graphics cards reviewed in this post draw power from the PCle x16 slot on the whole and do not need any external power connector. The GeForce RTX 2060 draws power from the PCle x8 slot from the system’s power supply, which is not external. However, the card requires 500W PSU for it’s working, so if your system isn’t able to provide that, you can connect an external power supply to add some more graphical oomph to the whole setup.
      If you need more info, don’t hesitate to ask.
      Thanks
