Next-gen ATX 3.0 power supplies from multiple vendors detailed inside

Seasonic, Silverstone, Asus and Thermaltake ATX 3.0 power supplies are ready for prime time in capacities ranging from 750W to 1650W for the most demanding graphics cards.

With next-gen GPUs around the corner, PSU makers are scrambling to release their products with the (very) famous 16-pin VHPWR connector and its 600W power rating. While AMD seems retaining the trusty 6+2 pin connectors, Nvidia is focusing on this new format on upcoming RTX cards. This will allow Nvidia GPUs to be powered with a single cable unless they exceed 600W of consumption, which doesn’t seem to be the case according to the latest rumors.

While these PSUs most likely cost a pretty penny, as long as they continue to perform decently for, say, five to 10 years, the price shouldn’t be an issue – we can call it an investment. Also, with rumors of higher GPU transient load coming, PSUs will have to deal with high power spikes for short durations – if they can’t, your computer will shut down. Best-case scenario, turn it back on and keep playing, but if you’re unlucky you might lose your progress, corrupt Windows files, or even lose cached data.

Seasonal peak

Starting with Seasonic’s Vertex series, we’re looking at 1000W and 1200W capacity PSUs, each available with 80 Plus Gold or Platinum ratings. All are fully modular with a single 16 pin VHPWR along with two 6+2 pin and two 8 pin PCIe CPU power connectors.

@harukaze5719 on Twitter posted screenshots of a retailer asking $243 for the 1000W Gold, $271 for the 1000W Platinum, $281 for the 1200W Gold and finally $319 for the 1200W Platinum .

Hela of Silverstone

Silverstone Hela 850R Platinum

Then we have Silverstone’s Hela 850R, a comparatively smaller PSU with a maximum output power of “only” 850W, but also featuring a 16-pin VHPWR connector capable of delivering 600W to a board chart. This represents 70% of the total power supplied via a single cable. It also has three 6+2-pin GPU power connectors and two 8-pin for the CPU.

While 850W might seem small, its Cybernetics Platinum certification certainly isn’t, indicating that it passed (among other things) Cybernetics’ transient power tests. The Hela 850R is also rated at 89-91% efficiency at 230V. For cooling, you can choose to activate a 0dB mode that keeps the 135mm fan off until it reaches 50% charge.

Asus ROG Loki

Asus Loki

Available in 1200W, 1000W, 850W, and 750W variants, the ROG Loki series should deliver plenty of power in a smaller SFX-L form factor – for SFF builds. All models are fully modular and include a single 16-pin VHPWR connector as well as three 8-pin CPU/GPUs. In terms of efficiency, the 1200W model is rated at 80 Plus Titanium while the rest hit a lower, but still good 80 Plus Platinum.

Backed by a 10-year warranty, Loki PSUs are priced at PHP11,930 (£180), PHP13,420 (£202) and PHP15,650 (£236) for the 750W, 850W variants and 1000 W, respectively, in the Philippines. .

Thermaltake Toughpower GF3

Thermaltake Toughpower GF3 1650W

First announced at Thermaltake Expo, the Toughpower GF3 PSU will be offered in 750W, 850W, 1000W, 1200W, 1350W and massive 1650W capacity, all certified 80 Plus Gold. The latter carries two 16-pin VHPWR connectors, while the others are limited to just one. These PSUs use a single 12V rail and are cooled by a 135mm or 140mm semi-passive fan, backed by a 10-year warranty.

Finally, inside there are Japanese capacitors as well as an LLC design with a DC-DC converter. The brand also talks about tight voltage regulation of around 3%, with less than 30 mV of ripple noise.
