One of the things that puzzle any pc builder is the number of devices that will run in your system. And to power them up, you will need a good Power Supply Unit (PSU).
This mainly depends on how much power your device truly needs. Which brings us to the question should you get a 750-watt or an 850-watt PSU?
Let’s put them both side by side as 750 vs 850-watt PSU and come to a conclusion about which one is right for you.
Differences Between 750 and 850 Watt PSU
Let’s start by checking the main differences between a 750-watt PSU and an 850-watt PSU. To make it convenient, we’re providing them as a quick difference table. Have a look –
| Factors | 750-Watt | 850-Watt |
| Capacity | Maximum 750 Watts | Maximum 850 Watts |
| Rating | Generally 80+ Silver rating | Generally 80+ Gold / Platinum rating |
| Overclocking compatibility | Efficient for mid-level to high-level systems | Efficient for high-level systems |
| SLI compatibility | Efficient for single GPU systems | Efficient for dual GPU systems |
| Cooling | Generally supports one to two fans for cooling | Generally supports two to three fans for cooling |
| Future Upgrade | Possibly not sufficient | Sufficient |
| Cost | Comparatively less expensive | Comparatively more expensive |
From the table, it’s pretty clear that the 850-watt PSU offers more benefits compared to the 750-watt PSU.
Getting Between 750 and 850 Watt PSU | More Power Means More Performance?
If you look at the numbers, there is not much difference between them. Only a 100 watts that sets a 750W and an 850W PSU. But does that bring in better or less performance, that is the main thing.
Let’s look at them and how they perform under different circumstances.
1. Performance and Output Difference
When you are talking about performances, both the 750W and 850W PSU go head-to-head on performance. They are both amazing power supply units that every gamer or heavy-duty pc user needs.
But the thing is that the powerful and advanced GPU, processor and motherboard are fine with a 650W PSU. This means a huge amount of power will be left unused in both 750W and 850W power supplies. For extra measures, you might invest in one if you are in need of a new PSU. Otherwise, your older unit will do you just fine.
2. Metal Rate Differences
Different metal rates make the PSU run more efficiently. At the same time, the metal rating makes them produce more power than usual. Which in return is not wasted like regular metals.
Normally the metal rating goes like Platinum, Gold, and Silver. The difference in performance is like 10-15% less or better. But if you are keen on getting a Platinum standard PSU, we suggest getting a 750W Platinum edition than 850W. This will help you get the right power output and no power on standby to get wasted.
3. GPU Can Run at Time
Both the 750W and 850W power supply can run only two GPUs. As we have told you earlier, the difference between a 100W in PSU isn’t that much, so they won’t be able to do you any good if you shift to 850W from 750W.
750W vs 850W PSU Verdict
If you are in dire need of a PSU and have an upgrade in mind, we suggest getting a 750W PSU rather than an 850W. It is a good waste of electricity and power if you ask us. In the meantime, too much power doesn’t always mean a good thing. It might also damage components of your pc without you knowing about it.
Frequently Asked Questions and Answers
Do I need an 850-watt power supply?
No matter how powerful the system setup you have, an 850-watt power supply is way over the chart. For a single setup system, 650 watts is the best PSU. But if you have more than that, then you can go for an 850-watt.
Is a 750-watt power supply overkill?
For some cases, like if you have a single GPU with 256Gigs of RAM, a 750-watt power supply would be overkill. But with two GPUs, a better processor, and a RAM setup, you will need a 750-watt PSU.
Is a 750-watt power supply good enough?
Yes. a 750-watt power supply is good enough to run two powerful GPUs and a good gaming pc with ease. Additionally, you can go for the Platinum-rated edition for better output than a silver one.
Is 850 power supply too much?
Yes. A regular pc with a mid-range setup with a good GPU will require somewhere from 440-550 watts at the top. But with two GPUs, a high-power processor, and a motherboard with an extra RAM setup, a 750-watt PSU is more than enough. From that perspective, an 850 power supply seems too much.
Conclusion
More power doesn’t always mean better performance. Some of the power of a maxed-out PSU draws extra electricity, which sometimes overheats the whole system. And if your device components do not match the power supply, you might have a hard time getting a good performance out of an amazing machine. So stick with the less is more policy and do your research before you buy a high-wattage PSU.
