In our testing, we’ve concluded that the best power 750W power supply to buy is Cooler Master’s V750 i Gold. The market for 750W power supplies is a bit stale at the moment, and while there are some cheaper and older PSUs that will be more than adequate for most consumers, there aren’t a great number of modern options that come in at a reasonable price point. And this is where the V750 i Gold comes in. It is a bit overkill for consumers that don’t have an RTX 4000 graphics card, but despite this, it competes very well with other alternatives on the market, and offers a well-rounded set of features.

Efficiency: 4.6/5

Cabling & Modularity: 4.7/5

Value for Money: 4.8/5

Our Verdict: 4.7/5

The Best 750W PSUs

1. BeQuiet Straight Power 11

Best 80+ Platinum

MPI_BeQuiet Straightpower 11 750W

BeQuiet’s Straight Power 11 is an awesome 750W platinum unit, designed with efficiency and silence in mind. The Straight Power 11 sports a Silent Wings 3 fans which is still an incredibly strong option in today’s market. The Silent Wings 3 fan uses an optimised fan blade design increasing airflow and ensuring silence and minimal power consumption.

This means that even under heavy operation the Straight Power 11 should remain quiet. It is also worth noting that this unit is fully modular, so you can plug in the cables that you need, when you need them.

However, the Straight Power 11 doesn’t support the ATX 3.0 standard which is used with the latest generation of NVIDIA GPUs.

This means NVIDIA users with an RTX 4000 graphics card will have to contend with the pesky adapters, which can be a turn off, if you’re attempting to avoid cable management. But despite this, the platinum efficiency rating will be well worth it for many looking to build a power efficient PC.



2. Cooler Master V750 i Gold

Best Overall

Original Review by Jay Harris: Cooler Master V750 i Gold Review – A Lower Wattage ATX 3.0 Option

Cooler Master’s V750 i Gold is a more recent addition to their gold rated power supply range. Much like their older options, the V750 i Gold is a very reliable unit designed to remain quiet and maintain consistent power delivery even under load. The V750 i gold has two notable strengths that are worth mentioning.

One is the support for the ATX 3.0 standard. This PSU comes with a 12VHPWR cable, so you can easily plug in your RTX 4000 graphics card without the use of an adapter, which should also make cable management much simpler too.

The second most notable feature is the use of a semi-digital platform. By plugging your PSU into one of the USB headers on your motherboard, you can control voltages, power, and fan speeds of the V750 i.

Best Silent

MPI_Asus ROG Strix 750W

The ROG STRIX 750G from ASUS has been a mainstay for us in a number of different PC builds that we’ve put together in the past. While the ROG STRIX 750G is not the newest option on the market, it still holds up incredibly well by today’s standards. There isn’t much to talk about on the features front of this particular PSU, but it is worth noting how quiet it is.

Cybenetics has given the 750G a noise rating of A which is pretty quiet. This means that even without headphones on, under loads the ROG STRIX 750G is going to be near-silent in its operation.

In terms of cabling, as expected, the 750G is fully modular, so you can pick and choose what cables you’re going to install.

Key Specs

Efficiency Rating80 Plus Gold
ATX 3.0 SupportNo
Zero-Fan ModeYes

This should save some hassle when it comes to cable management. The ROG STRIX 750G also comes with ten year warranty, so if for some reason it doesn’t survive general usage, it should be relatively easy to organise a replacement or a refund.
