Corsair SF600 Platinum SFX (CP-9020182-NA)

The Corsair SF600 (part number CP-9020182-NA) belongs to Corsair's SF Series, a line of small-form-factor SFX power supplies. Corsair's product page presents it as a 600 W, 80 PLUS Platinum certified, fully modular unit that offers, in Corsair's words, the low-noise performance of an elite Platinum supply in a form factor meant for the world's best small-form-factor PCs. This entry reports what the product page says and nothing more. There are no test results, no measurements of our own and no price here, because Corsair's page gives no launch date and a price would be a claim we cannot source. Every figure below is a manufacturer specification unless it is marked as arithmetic. The unit is useful to understand even if you are not building a small PC, because it shows what a compact power supply must trade to fit into a small space, and what Corsair does to offset that.

The SFX form factor

SFX is a compact power supply standard, smaller than the ATX size used in most full-size cases. Corsair lists the SF600's dimensions as 100 mm by 63 mm by 125 mm and its weight as 2 kg. Multiplying the three figures gives roughly 0.79 litres of volume (arithmetic from Corsair's numbers), a very small footprint for 600 W of continuous output. The page describes the design as a high-density arrangement that delivers high efficiency and low noise without compromising continuous power, reliability or quality. Because many small cases are built around SFX, Corsair also states that there is a difference between SFX and the longer SFX-L form factor, and its guide section links to an article on that difference; before you buy for a specific case, confirm which of the two the case supports. Our comparison of SFX versus ATX power supplies gives the background on how the two sizes relate.

An ATX bracket in the box

The package includes an SFX-to-ATX adapter bracket, which lets the SF600 be installed in any ATX-compatible case. Corsair says the new bracket offsets the mounting location, so there is more space inside a standard ATX chassis to tuck away excess cable out of the airflow path. That makes the unit a candidate for a regular case too, which is a practical point: a power supply that fits both SFX and ATX mounts gives you flexibility when you later move your parts to a larger case. If you are still choosing a case, our guide to ATX, mATX and ITX case form factors explains how the sizes relate to component choice.

Efficiency: 80 PLUS Platinum

Corsair states that the SF Series is 80 PLUS Platinum certified and delivers power with over 92 percent efficiency, which it says keeps energy consumption, noise, temperatures and your power bill low. Platinum is one of the higher tiers of the 80 PLUS scheme, and the exact efficiency at each load level is set by the certification; the product page gives the headline figure but no load-by-load table, so this entry does not invent one. If you want to understand how the tiers compare, see our guide to 80 PLUS Bronze versus Platinum efficiency.

Cooling and noise

The fan is 92 mm, which Corsair describes as an upgrade on the 80 mm fan of the SFX standard, reducing noise and improving performance at demanding loads. A larger fan can move the same amount of air more slowly, which is why bigger fans are usually associated with lower noise, but the page states the benefit and gives no decibel figures, and neither do we. The tech table lists a rifle bearing as the fan bearing technology. Zero RPM mode is supported: at low and medium loads the fan does not spin until it is needed, giving near-silent operation. The rated continuous output temperature is 50 degrees C and the mean time between failures is 100,000 hours. Corsair states no Modern Standby support for this model and lists Intel C6/C7 sleep-state compatibility as supported.

Internal design and components

Corsair describes an innovative internal design that swaps wires for soldered printed circuit boards, and says it delivers superb performance, stable voltages and ultra-low ripple and electrical noise. The unit uses 100 percent Japanese 105 degrees C capacitors, described by Corsair as high-end electrolytic capacitors that provide the unwavering power and long-term reliability expected of a Corsair power supply. These are design statements from the manufacturer; they describe the intent of the design, not behaviour that this site has verified. The protections listed are over-voltage, under-voltage, short-circuit, over-temperature and over-power. The unit conforms to ATX12V v2.4 and EPS 2.92 standards, and the page does not list ATX 3.x or a native 12V-2x6 cable, so check the graphics-power connector you need before pairing it with a recent high-power graphics card.

Cables and connectors

The SF600 is fully modular and comes with premium individually sleeved cables in an all-black finish, with a flexible paracord sleeve. Corsair says individually sleeved cables have a lower profile and greater flexibility than flat or sleeved cable kits, which eases routing and cable management in a tight case. The tech table lists one ATX connector, four SATA connectors and three PATA (Molex) connectors, and no floppy connectors. The package contents are the power supply, an AC power cord, a DC modular cable set, cable ties, a Corsair case badge and a user manual. Four SATA connectors are enough for a typical small build with a couple of drives; if you need many drives, count the connectors before you buy.

Rails, warranty and support

The continuous power is 600 W. The tech table lists the single/multiple 12 V rail toggle as No, so there is no rail switch. It also lists the unit as multi-GPU ready. The warranty is seven years, which Corsair calls your guarantee of reliable operation across several system builds, and it says Corsair global customer support is ready to help with installation or use problems. As with any warranty, read the terms on Corsair's own pages for the details that apply where you live.

What the product page does not state

A careful reader should also note what is missing. The page gives no per-rail current limits for this unit, no efficiency figures at individual loads, no noise figures in decibels, no fan speed and no dimensions for the included bracket. It does not name a launch date or list a price. Because we only report what the manufacturer states, none of those gaps are filled here. If one of them matters to your build, for example the amperage available on the +12 V rail for a particular graphics card, look for the unit's label or manual, which the page lists in its downloads section, before you buy.

Where it sits and how to compare it

The SF600 is the only SFX unit in this site's Corsair coverage; the other small-form-factor supply here is the 850 W SFX-format model from Cooler Master, the Cooler Master V850 SFX Gold. The two differ in rated power, efficiency tier and warranty, so a direct look at the numbers helps: open the side-by-side comparison to see them next to each other, or browse the full power supply category. To choose a quiet build overall, our silent PC build guide is a good companion. Everything on this page comes from Corsair's product page, and how the supply performs in your own build depends on your components, your case and your ambient conditions.
