Behold the Seasonic Prime TX-1600: a juggernaut amongst its peers. With excellent performance and a stellar 12-year warranty, it's a true investment in reliability. Running silently at up to 800W with its passive design, it ensures peace in your setup, but it's not the most budget-friendly option.
Atmos is Chieftec's latest 80PLUS Gold-rated power supply series built to support the ATX 3.0 specification, aimed at the price-conscious but quality-seeking buyer. Today we're testing out the capabilities of the 850 W unit.
The NZXT C1200 Gold is a high-performance power supply, meeting the strict ATX v3.0 and PCIe 5.0 requirements. It has a 600 W 12VHPWR connector, which makes it compatible with any current or upcoming GPU. Thanks to the Channel Well platform, performance is good, too.
The Thermaltake Toughpower GF3 1650 W is the only PSU on the market that offers two 12VHPWR connectors, each capable of 600 W. This unit can support two NVIDIA RTX 4090s with their power limits set to max, along with a powerful CPU and other power-hungry components.
The be quiet! System Power 10 750 is among the worst affordable, branded PSUs I have evaluated. The competition is way ahead in this category, offering higher performance, quality, and universal voltage compatibility (100-240 V input) at about the same price.
The Thermaltake Toughpower GF3 with 1000W max power is ATX v3.0 and PCIe 5.0 ready and offers good performance for its $200 price point. It has high build quality and excellent voltage regulation. Thanks to a fully modular design that PSU will be a breeze to install, and the 10-year warranty will give you peace of mind for a long time.
The Thermaltake GF3 with 750 W max power is an ATX v3.0 and PCIe 5.0 ready PSU, meaning that you won't need to use the dreadful 12+4 16-pin adapters since it has a native 12VHPWR cable, rated at 600 W. The PSU's performance is high, and it also has a quiet operation.
The MSI MEG Ai1000P has high build quality and achieves top performance in all tested sections. It has the best regulation of all PSUs we ever tested! Moreover, it is among the few 1000W PSUs tested so far offering both ATX v3.0 and PCIe 5.0 compatibility.
The Corsair HX1500i has good performance and top-notch build quality. Designed with extended functionality through Corsair's iCUE software, you can monitor and control some of the PSU's vital functions. Lets see how the PSU fares through our comprehensive review!
The Corsair CX450M is an affordable PSU with good overall performance and build quality, suitable for non-demanding systems. The semi-modular cable design and compact dimensions will make your life easier during installation.
The first ATX 3.0 compatible SFX power supply falls into our hands, and we don't miss the opportunity to evaluate it thoroughly. The Channel Well Technology CSX 850M-G offers high performance, coming with a single 12+4 pin PCIe connector.
The Corsair CX-M Series 650 W is one best available budget PSUs. It performed very well in our tests and runs reasonably quiet. Given the affordable positioning it shouldn't be an issue that it lacks the 12+4 pin PCIe connector for future GPUs, most budget PSUs won't meet the strict ATX 3.0 requirements anyway.
The Gigabyte UD750GM uses a better version of the platform used in the P750GM, with vastly improved protection features. Overall performance is also higher, but still needs more work to be competitive. A lower price might help since the Corsair RM750x—the king of this category—only costs $10 more.
The Cougar Polar 1200 is the best Cougar power supply I have tested so far. Its build quality is high, and performance competes with the ASUS ROG Thor flagship using a modified Seasonic Prime Platinum platform. The Cougar Polar not only performs as well overall, but it's also very quiet.
The Gigabyte UD850GM is a decent choice at around $110. It lacks a bit in overall performance, but has fully working protection features, compact dimensions, and won't force you to wear earplugs as long as it isn't pushed hard. I expect an upgraded version with a 12VHPWR connector for future GPUs soon.
The Gigabyte UD1000GM PG5 is the first available PSU with a 16-pin PCI-Express 5.0 connector. The only graphics card requiring such a connector is the NVIDIA GeForce RTX 3090 Ti, which also comes with an adapter, but the upcoming 4000 series will need it as well, so it is good to be ready.
The Seasonic Core GX-500 performs well and is silent under normal operating conditions. Its fully modular cable design and compact dimensions are great, too. If only you could find it at a lower price.
Available for $65 and with great performance per dollar, the Raijintek Ermis 550B does manage to attract attention, especially as there currently aren't many budget-oriented SFX offerings available.
There are very few desktop PSUs with 2 kW or more maximum power output. The Cooler Master M2000 Platinum is one. While a good performer and very efficient at even full load, it is very expensive, only has 200–240 V input, and isn't ATX v3.0 ready.
The be quiet! Pure Power 11 FM 1000 W costs less than the Corsair RM1000x and EVGA 1000 G5, which makes it a good price/performance pick. This is the best platform I have seen from HEC, but is it good enough to meet the competition eye-to-eye?
The Seasonic Focus SPX-750 offers good overall performance, but is struggling to compete with the Corsair SF750 Platinum in most areas. Its fan-speed profile and over-temperature protection also require further tuning.
The AQIRYS Pulsar LS White 750 W has a nice exterior, matching white, fixed cables, and a cool model name. However, is that enough to make it stand out of the crowd in the 750 W 80 PLUS Bronze category where it has to face units like the Corsair CX750M, XPG Pylon 750, and Thermaltake Smart BM2 of similar capacity?
The be quiet! Pure Power 11 FM 850 W is a good PSU, but the competition is tough. Some changes are required to increase performance and more effectively meet the competition from Corsair, EVGA, ASUS, and Seasonic. A price drop would also help, especially in the US.
The 1st Player SFX 750 W is competitively priced, which ensures a high performance per dollar ratio. Build quality of this fully modular PSU is good, making this compact power supply a decent product at a fair price overall. The included seven-year warranty also ensures peace of mind.
The DeepCool PQ1000M is a decent recommendation, based on a Seasonic design, pairing high capacity with low-noise operation. However, its strongest competitor is the Corsair RM1000x, which costs less and performs better due to its modern CWT platform.
