Corsair SF600 (2018) 600W SFX Power Supply Review

Corsair is no stranger to the enthusiast computer power supply market, and most of its PSUs are built for ATX form factor cases. Corsair does however dabble a bit in the SFX end of the spectrum which tries to shoehorn as much power as possible into the smallest space possible. Let's see what the new SF600 is all about.

Overview

The first thing we are going to look at with the Corsair SF600 2018 is its packaging, accessories, and documentation. While normally none of these items is a make or break item for a power supply the packaging quite often contains a lot of information about the product we are purchasing. The inclusion of an owner’s manual that provides actual information about our product is also of great help in many situations. Accessories are almost unnecessary with a power supply as the unit is self contained, unless it is modular, but there cases where a manufacturer can include useful accessories to make installation, routing and use more efficient.

The packaging of the Corsair SF600 2018 looks a lot like the packaging we saw on the original SF600 a couple of years ago. The front of the packaging has a picture of a SF600 2018 along with a few seals (including an 80 Plus Platinum label which we find listed on the 80 Plus website). Other than that, the front of the packaging has some advertising about having "Fully Modular DC Cables," "105C Japanese Capacitors," "Zero RPM Mode For Low Noise Operation," and a seal indicating the unit has a 7 year warranty. When we move to the rear of the packaging, we find more advertising about efficiency and fan noise including graphs for both features. We also see the power table which we have reproduced below. As we move around to the sides of the packaging, we find the connector count which we have also reproduced below.

The power information for the SF600 2018 is identical to that of the previous SF600. As such, we again see a single 12v rail rated at 50A or up to ~100% of the unit's total capacity if necessary. When we look at the minor rails, we see that this unit has up to 20A available on each of the 3.3v and 5v rails with a cumulative cap of 120W. Paired with this output, we find 2 PCIe connectors, 3 Molex connectors, and 4 SATA connectors. This is very similar to what we saw with the SF600 and this arrangement is certainly enough for the VAST majority of users looking at such a product.

Once we open the packaging of the SF600 2018, we see the usual assortment of items including the power supply, power cable, mounting screws, zip-ties, flash drive, user manual, warranty card, "Important Information," and an ATX adapter plate. When we look at the paper products we get, we again see that Corsair has included a 100 page long user manual. Also, just like last time, all that is in this manual that is written in 10 languages are installation instructions, connector counts/lengths, power table, the fan curve we saw on the package, the efficiency curve we saw on the package, and that is about it. So, we get A LOT of paper for not a lot of information which is just very weird. SilverStone, and others, do a far better job more concisely than this so there is no excuse for this today. Along those same lines, the warranty card and the "Important Information" largely duplicate each other or the user manual. in the end, it is sort of like Corsair has three groups of people writing their documentation and none of them talk to each other. So, while we like thorough documentation we also like it to be concise documentation and this is neither. Let's move on then to the Build Quality and see how the SF600 2018 looks there.
