The best power supplies come in all sizes and capacities. In terms of SFX units, Corsair's SF series is one of the best lineups out there. If you're particularly shopping for a 600W capacity, you can score the SF600 for less than $120.

The SF600 comes in two flavors. The 80 PLUS Gold variant retails for $124.99, but can be had for $84.99 after a $20 rebate (opens in new tab). The 80 PLUS Platinum variant, on the other hand, normally sets you back $144.99. For this Cyber Monday, however, it can be yours for just $109.99 (opens in new tab) after the same $20 rebate.

Sporting premium components and Japanese 105°C capacitors, the SF600 power supplies are designed for high-performance systems that fit into the mini-ITX form factor. The SF600 is characterized by its first-class performance and very quiet operation. It relies on a single 92mm cooling fan with a built-in zero RPM mode where it only spins up at high loads.
