Number 3. Cooler Master MWE Gold 850 V2 – Best Budget PSU For Ryzen 7 7800X3D

If you’re looking for a great PSU to run your next high-end build that doesn’t cost a fortune then you should consider the Cooler Master MWE Gold 850 V2.

The design of the MWE Gold is simple and it doesn’t draw any attention towards itself. On the bottom, there is a single 120 mm fan that is quiet and removes heat efficiently. Cooler Master didn’t implement any “Zero RPM” setting on the PSU which has a great benefit and a slight trade-off. Since the fan is always spinning, the PSU remains cool at all times and the internal components last much longer. On the downside, the PSU becomes audible at high loads and there is always the issue of dust settling inside which wouldn’t be a problem if the fan wasn’t spinning.

Power-wise, the MWE Gold is fantastic and can easily run a high-end PC with a Ryzen 7 7800X3D and an RTX 4090. It is one of the best power supplies that can handle high wattage GPUs like the RTX 4090 without costing too much.

It doesn’t have a PCIe 5.0 12VHPWR cable so you will need to get an adapter separately if your GPU does not use the standard 6 or 8 pin power connectors.

In terms of the competition, it is the only PSU under $100 that I can recommend because it provides 850 watts of power and is a reliable unit. Most PSUs under $100 top out at 750 watts and the ones that are offering 850 watts of power are not reliable.

For around the same price as the Cooler Master MWE Gold 850 V2, there is the Gigabyte UD850GM however Gigabyte’s reputation in the PSU market is still not favorable. The UD850GM is supposedly an 80 Plus Gold PSU but I would still steer away from it considering Gigabyte still has to recover from their exploding PSU fiasco.

Another competitor is Thermaltake’sToughpower GF1 (2024) 850 Watt PSU. This used to be one of the best PSUs for budget PC builds thanks to offering Platinum grade experience for the price of a Gold-rated PSU, but the new 2024 model is not the same as the older 2019 model which is now discontinued. The GF1 should be avoided as the 2024 model is a completely new unit with cheaper parts inside but with the same name which is very confusing.

All in all, the Cooler Master MWE Gold 850 V2 is a great PSU and the only reliable option under $100 for anyone looking to power a top-of-the-line PC with a Ryzen 7 7800X3D and a top-end GPU like the RTX 4090 or RX 7900 XTX. While other more expensive alternatives offer a slight step up in terms of features, the MWE Gold focuses on offering the best power delivery at the lowest possible price.

To sum up what I like is that it’s a…

• 850 watt PSU for the price of 750 watts
• Silent under heavy loads
• Handles high wattage GPUs

On the downside…

• No 12VHPWR Connector included
• No “Zero RPM” mode

RATINGS:

• Design: 8/10
• Power delivery and efficiency: 9/10
• Cooling and noise: 7.5/10
• Value for Money: 9.5/10
• Overall Rating: 8.5/10

Number 2. ASUS ROG Thor II Titanium 1600W – Best Premium PSU For Ryzen 7 7800X3D

If you need the absolute best power supply to power your PC for the next decade, then it doesn’t get better than the ASUS ROG Thor II Titanium 1600W.

I usually don’t wonder how good a PSU should look, but this one definitely stands out from the rest considering its aggressive gamer aesthetics with full ARGB lighting.

The most prominent feature of the ROG Thor and other ROG PSUs is the OLED display. It monitors power draw in real time and shows how much power is being drawn from the wall without the need of a power meter. This is great although I do wish this monitor showed more information or allowed switching between the type of information being displayed.

On the top of the PSU, there is the large 135 mm fan which is covered by a stylish aluminum grill which helps accentuate the overall premium look and feel of this unit.

Now for the most important aspect of any PSU; the power delivery. The ASUS ROG Thor II Titanium 1600W is hands-down the single best PSU – period. It is an 80 Plus Titanium rated unit that’s also one of the few PSUs to receive a Titanium badge by Cybenetics which is rare given how rigorous their testing methodology is.

The ROG Thor is always more than 90% efficient between 150 to 1500 watts and it is the most efficient between 250 and 600 watts of usage where the efficiency is above 94%.

It can deliver a full 1600 watts of power to all the components which means that it can fully run 3 RTX 4090 gpus with the rest of the system still having almost 250 watts left.

It is also ready for the next generation Nvidia and AMD GPUs as well. If rumors are to be true, the RTX 5090 is said to consume around 600 Watts of power which will completely saturate the 12VHPWR connector. Even then, 2 RTX 5090s will have no issues working with this PSU. What is incredible is that even with that much load transient spikes are a non-issue and ASUS is so confident, that they even offer a full 10 year warranty.

Even with a near full load on the PSU, the overall efficiency still remains the most impressive aspect of the ROG Thor compared to any other PSU out there and, because of that, the fan has to barely work.

The average noise recorded is just 14 decibels which is so low that you can’t even hear it with your ears next to the PSU. The fan does not spin at all when the PSU is drawing up to 1000 watts of power and even after that, you can barely feel it spin at 1300 watts. The ROG Thor is only slightly audible when completely using 1600 watts of power and thus Cybenetics has given it a near-perfect score for both efficiency and noise.

With so much praise coming one’s way, it is perfectly acceptable to be skeptical but I can’t fault this PSU much because it truly is a perfect product. It will last a very long time and I am sure you will change multiple PCs before you need to switch this PSU. That being said, the single biggest drawback is the price.

There are a lot of power supplies like the be quiet! Dark Power Pro 13 1600W or Corsair AX 1600i that get the job done. They aren’t nearly as perfect as the ASUS ROG Thor, but they also cost much less. If however, budget is not an issue, then there really is nothing better than this unit. It is very powerful and makes sense as a one stop solution for anyone with highly flexible power needs.

In conclusion, the ASUS ROG Thor II Titanium 1600W is the endgame PSU. It has everything that a powerful high-end PC with the Ryzen 7 7800x3d needs and would last very long for any type of a PC no matter how powerful.

To sum up what I like is that there is…

• Lots of wattage for any type of system load
• Dead-silent fan
• Dual 12VHPWR connectors

On the downside…

• Very expensive

RATINGS:

• Design: 9/10
• Power delivery and efficiency: 9.5/10
• Cooling and noise: 9.5/10
• Value for Money: 6/10
• Overall Rating: 9/10

Number 1. Corsair RM1000e (2023) – Our Top Choice

If you need a no-frills modern PSU for your next Ryzen 7 7800x3d PC build with great features, then the Corsair RM1000e should fit the bill.

The design is clean, simple, and professional with a hint of creativity sparkled on. The sharp edges on the side of the PSU have been flattened out and the 120 mm fan grill has triangular vents. Both of these give the PSU its unique design identity.

The general performance of the RM1000e is top-notch and it can handle just about any type of load. It is fully ATX 3.1 and PCIe 5.1 certified and ready which is a great thing since it means that it was designed specifically for GPUs like the RTX 4090. A lot of ATX 3.0 PSUs are not fully certified, instead, some vendors are simply including a test 12VHPWR cable with no transient electric surge protection.

Cybenetics has certified the RM1000e with a Platinum rating for power and A- for noise and for good reason. The power delivery is incredible and the PSU remains above 90% efficient almost all the time. With such great efficiency, the unit remains silent, however that doesn’t mean that the fan remains dead still all the time.

When using this unit till 450 watts, the fans spin very slowly and occasionally stop. Typically it isn’t an issue to make a fuss about, but a Zero RPM mode should work all the time for a specified range at least – say even 200 watts. Zero RPM modes help the PSU stay clean without any dust being sucked in and given how slow the fan spins, it would barely bring the temperature down. Still, this doesn’t in any way reduce the worth of this unit.

What I think is the most interesting aspect of the RM1000e isn’t the PSU itself, but rather its extremely tough competition. There are just too many PSUs that compete with it, both great and terrible. After careful inspection, I’d say that the closest competitor to the RM1000e is the be quiet! Pure Power 12 M 1000W.

The prices for the 12 M and Corsair RM1000e fluctuate but the 12 M is ever so slightly more expensive than the Corsair RM1000e. The competition is fierce and the only reason why I am giving the RM1000e the win is because it gets dead silent while the Pure Power 12 M is slightly audible at all times.

In conclusion, whether you’re building a $1000 or a $3000 PC, the Corsair RM1000e is quite hard to beat. It has enough room to power an RTX 4090, and even the rumored RTX 5090, while still having room to power 400 watts more. For around $150, it’s one of the best deals for any PC component right now and it is perfect for a PC with the Ryzen 7 7800x3d.

To sum up what I like is the:
Platinum-level efficiency for a Gold-rated PSU
ATX 3.1 and PCIe 5.1 certified

On the downside…
Zero RPM fan mode is inconsistent

RATINGS:
Design: 8.5/10
Power delivery and efficiency: 9.5/10
Cooling and noise: 9/10
Value for Money: 9/10
Overall Rating: 9/10
