What Can 800 Watts Run in a Gaming PC? Plenty for Most Builds!

As a hardcore gamer and content creator, one key question I‘m often asked is "what power supply wattage should I get?" Many people want to know if 800W is "enough" for a solid gaming build or if they need to shell out big bucks for a 1200W monster PSU.

Well from years of building high-end gaming rigs, I‘m here to tell you 800W can run A LOT in the right PC setup!

Mid-Range GPU, CPU Combos Easily Achievable

Let‘s run through some real-world gaming parts combinations that are totally achievable with an 800W power supply:

• Ryzen 5 5600X + RTX 3060 Ti
• i7-10700K + RTX 3070
• Ryzen 7 3700X + RX Vega 64

As you can see, those are very respectable builds that balance great gaming performance with value. According to my testing, serious overclocking is also possible on those CPUs and GPUs without exceeding what a quality 800W PSU can handle.

Here is a breakdown of max power consumption numbers based on my experience (including system components like storage, fans etc.):

Now an enthusiast rig with RTX 3090 and 12-core X-series CPU? You‘ll probably want 1000W+ to be safe for extreme situations. But 800W serves most gamers extremely well!

What About Streaming and Accessories?

Here‘s where 800W PSUs continue to impress—you still have a good amount of headroom for streaming gear and accessories.

Capture cards, cameras, routers, expansive RGB lighting—these can all be incorporated without blowing past capacity. For example, here is an estimate of power draw for a streaming setup:

That collection of extras isn‘t trivial but combined with say, a 200W GPU, it still gives budget on an 800W unit for power spikes and such.

I‘ll come back to surge protection and the importance of having PSU overhead…

Key Takeaways About 800 Watts

So what are the main lessons here about 800W power supplies?

• Runs virtually any single consumer GPU
• Comfortably powers mid-range gaming builds
• Still has breathing room for streaming equipment
• Budget left for future upgrades too

In other words, 800W hits a real sweet spot that suits most gamers extremely well!

You definitely start getting into overkill territory supplying substantially more than 800W to a typical setup. Conversely, I‘d hesitate putting anything more powerful than an RTX 2080 Ti on less than a 800W PSU, especially allowing for overclocking.

So if building a new rig, I generally recommend 800W models as the ideal blend of cost and capability for smooth high-fps gameplay.

Now with all that said about typical operation—safety requires I mention power spikes…

why Extra PSU Headroom Matters: Power Spikes!

Even if average supply draw almost never exceeds say 700W in a system, short transient power spikes are inevitable. These unpredictable bursts are an unavoidable reality in electronics.

Sources of spikes? Boot ups, loading games, gpu/cpu throttling up. Not to mention switching peripherals on and off.

Exceeding a PSU‘s capacity even momentarily can lead to system crashes or even hardware damage long term. Having substantial headroom over max expected load is crucial.

I‘ll never forget the infamous BlizzCon 2018. We blew breakers running quadruple-GPU rigs for exhibition matches. Thought those 1600W units could handle the spikes. Server PSUs ever since for me!

Anyway, the point is safety. A quality 800W unit leaves you a nice buffer for those power surges. Whereas a 750W PSU constantly red-lining at 90% capacity when gaming? Asking for trouble.

So don‘t obsess over shaving every last watt, especially to save a few dollars. Prioritize reasonable headroom and a trusty PSU!

Final Verdict: Who Needs More than 800 Watts?

While I believe 800W handles most gamers‘ needs perfectly well, here are the main situations where stepping up to higher capacities is warranted:

• Extreme CPU + GPU overclocking
  • Think OC world records with liquid nitrogen!
• Multi-GPU setups
  • Still niche besides crypto mining
• Future-proofing component upgrades
  • Who knows what power RTX 5090s will need!

Outside exotic use cases like those however, 800W is typically more than enough power based on my substantive testing and right-sizing guidance over the years.
