Corsair SF600 600W SFX Power Supply Review

Corsair has gotten into making computers smaller lately with its Bulldog 4K Living Room Gaming System, and now it is going to share its SF600 power supply that follows the SFX standard form factor, which is tiny for a 600 watt PSU. Given its diminutive stature, has Corsair packed it to the gills with good power?

Overview

The first thing we are going to look at with the Corsair SF600 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 is a bit different from previous Corsair units we have seen and it is also tiny (but so are SFX units so.......). The front of the packaging has a picture of a SF600 along with a few seals including an 80 Plus Gold label. When we check the 80 Plus website, we see that this unit is listed as certified by 80 Plus. 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. Interestingly though, the warranty on this unit has recently been extended by Corsair to 10 years. Anyway, when we move to the rear of the packaging, we find a lot more advertising about efficiency and fan noise including graphs for both features. We also see here, on the rear of the package, that there is a 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 is as we would expect from a modern 600W power supply. This particular unit boasts 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, 4 Molex connectors, and 4 SATA connectors. This arrangement of connectors could only be classified as anemic if this were an ATX12v power supply. However, today, we are looking at an SFX unit and most users will be using this unit in cases that can not fit a lot of the components that we generally see 600W units powering (for a number of reasons, one of which will become apparent below). So, this arrangement is certainly enough for the VAST majority of users looking at such a product, or use it in a "larger" case.

Once we open the packaging of the SF600, we see the usual assortment of items including the power supply, power cable, mounting screws, zip-ties, flash drive, user manual, and warranty card. That said, what is missing so far that we have seen from all of the other SFX (1,2) units we have reviewed? An ATX adapter plate, but Corsair will sell it to you for $5.99 plus shipping (a grand total of $10.88 with the least expensive shipping I could select). So, users won't be using this in small cases that call for an ATX power supply out of the box which is unfortunate since other SFX options we have reviewed provide this as part of the retail package.

Moving on, in an effort to make up for previous sins, or so it would seem, the user manual that Corsair includes with the SF600 is 100 pages long! 100! Why? We want good documentation, useful documentation, not أ€ la recherche du temps perdu! Mitigating this somewhat is the fact that the manual is printed in 10 languages and covers both the SF600 and the SF450. So, what is written 10 times in this manual? Well, some 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. Unfortunately, it seems that while the manual is long it is also sparse. Let's move on then to the Build Quality and see how the SF600 looks there.
