Corsair’s SF450 and SF600 PSUs to make your small form factor PC run silently

With small form factor PCs on the rise, it should come as no surprise that one of the industry’s leading proponents, Corsair, would be unleashing onto the market its first-ever lineup of SFX form factor PSUs.

Despite being compact, both the 600W SF600 and 450W SF450 claim to be immensely efficient, boasting 80 Plus Gold certification. Likewise, according to Corsair itself, they also use 100 percent 105C rated Japanese capacitors.

Though fitting colossal-sized components into a cramped SFF enclosure may seem like an impossible feat, Corsair relieves some of that stress by making its latest PSUs fully modular. As a result, the installation process isn’t nearly as much of a chore as it would be otherwise.

Any SF450 purchase will entitle you to an ATX connector, EPS connector, four 4-pin peripheral connectors, a pair of PCI-E connectors, and four SATA connectors. You can expect it to exhibit a maximum of 37.5A over a +12V rail.

While the specs on the two models are largely the same, it’s worth noting that the bulkier SF600 model bears only a single 4-pin peripheral connector rather than the four advertised on the SF450. Nonetheless, everything else on the two models is exactly alike.

Like the SF450, the SF600 also takes advantage of a single +12V rail design, but also exhibits up to 50A for more power intensive components.

Nevertheless, both the SF450 and SF600 make use of Corsair’s “Zero RPM Fan Mode,” meaning the cooling fan is only enabled when the power unit demands it. As a result, they’re supposed to run completely silent at both low and medium loads.

You can pick up the SF450 and SF600, starting now, for $90 and $120, respectively. For anyone seeking the flexibility of a modular, small form factor PSU with the serenity of a virtually mute cooling system, either unit seems like a solid buy.

I found the best Prime Day deal on a tablet hidden beyond Amazon
Microsoft Surface Pro 12-inch, stylus, and keyboard.

A good tablet can take your productivity to the next level, but a boring one will find a niche use and eat dust on a table or couch for most of its time. I love iPads and have been pushing them – as far as I can — to act as my primary computing machine for nearly half a decade now. It has never managed to replace a proper laptop, like a MacBook Air or a Windows machine. 

Why not buy a Windows laptop, you might ask? Well, Windows-powered tablets, especially those Surface devices sold by Microsoft, are pretty expensive. I love the new 12-inch Surface Pro, but at $799, it felt like a steep purchase despite its impressive specifications.
