What you need to know about the power requirements of the RTX 3080

One of the most highly anticipated Graphics Cards of all time, the new RTX 3080, sits at the top of the consumer friendly lineup only bested by the Titan replacing (wallet destroying) RTX 3090.

With the new RTX 3090 not only comes a new Founders Edition card design, utilising push pull fans, but also a hefty 100 Watt power bump in recommended Power Supply units over the outgoing 2080 Super.

Geforce RTX 3080 Power Supply Requirement

We’ve seen the full spec list above, but let’s focus now on the Power Specs, specifically what size PSU you need for a RTX 3080.

That’s right an eye watering 750W Power Supply is the new recommendation.

But wait, don’t toss aside your existing power supply just yet, let’s dive in a little deeper to what (2) is all about..

Recommendation is made based on PC configured with an Intel Core i9-10900K processor. A lower power rating may work depending on system configuration.

So that’s using a super high end (and a little toasty) Intel Core i9-10900k, It’s therefore reasonable to assume that you might just get away with a lower powered power supply if your other components need a little less juice.

However, for the purpose of our recommendations we are only recommending 750+ w cards to ensure comparability.
