Russ ;x Posted March 8, 2020 Posted March 8, 2020 The ROG Strix 650 unit offers high performance since it uses the po[CENSORED]r Seasonic Focus Plus Gold platform, and it features silent operation. Those benefits come at a high price, though, and with notably less money, you can get yourself either a Seasonic Focus Plus Gold with similar capacity, or a Corsair RM650x which achieves even lower noise output. Asus should try to lower this product's price and get closer to the competing offerings, to have an advantage over them. The ROG Strix PSU line only has two members, for now, with 650W and 750W max power. In this review, we will evaluate the 650W model, which has enough power to meet the requirements of a system featuring a single high-end graphics card, and a strong, multi-core CPU with both clocked at stock speeds. If you plan to overclock heavily, you should get a much stronger power supply since power consumption increases higher-than-stock speeds. Although the ROG Strix 650 shares the same platform with the Seasonic Focus Plus Gold with similar capacity, it has larger dimensions because it uses beefier heat sinks, that requires a larger PCB. Thanks to the larger heat sinks, the fan speed profile can be much more relaxed and this leads to a low overall noise output, despite the use of a double ball-bearing (DBB) fan. The DBB fans have high tolerance at increased operating temperatures, something that is not the case with Fluid Dynamic Bearing (FDB) ones, but they also produce higher noise levels under the same conditions. This is why they are not preferred in power supplies, where FDB fans dominate. Nevertheless, if you can pair a DBB fan with an optimal fan speed profile, the outcome can be 100% satisfactory, as is the case with both ROG Strix models.
