Introduction and Features

Introduction

Corsair recently introduced two new SFX small form-factor power supplies into their already formidable lineup of PC power supplies. The SF Platinum Series includes two SFX models, the SF450 (450W) and SF600 (600W). They are very similar to the two current Gold Series SFX units currently on the market but thanks to some tweaks in the circuit design and manufacturing process the Platinum Series SF450 and SF600 now deliver Platinum level efficiency.

Both new power supplies feature fully modular cables with individually sleeved wires. The SF450 and SF600 feature a Zero RPM Fan Mode for silent operation at low to medium power and come backed by a 7-year warranty. And an SFX-to-ATX mounting bracket is included in the box. We will be taking a detailed look at the Corsair SF600 Platinum power supply in this review.

Here is what Corsair has to say about their new SF Platinum Series:

View Full Size

The SF Platinum Series comes in both 450W and 600W models. CORSAIR SF Platinum Series SFX (small form factor) power supplies are fully modular and optimized for silence and high efficiency. Zero RPM Fan Mode means that the fan doesn’t even spin until the power supply is under heavy load, and the fan is custom-designed for low noise operation even at high loads.

And unlike other SFX power supplies, the SF Platinum Series features a 92mm fan, as opposed to an 80mm fan. This allows the fan to move the same volume of air at a lower RPM.

The 80 Plus Platinum rated efficiency saves money on your power bill, and the flat black cables are fully modular, so you can enjoy fast, neat builds. And, like all CORSAIR power supplies, SF Platinum Series is built with high-quality components, such as 105°C rated Japanese capacitors, and is guaranteed to deliver clean, stable, continuous power.

In the cable/connector chart, what does the final column mean? Is it number of cables times number of connectors, or number of cables times number of connectors? Either way, it makes no sense. The SATA cell says 4x4, but there couldn't possibly be four SATA cables with four connectors, Corsair says the SF600 only for four connectors in total.

Yes, a little confusing - not sure why they wrote it that way. You are correct (as noted several other places in the review) there is one SATA cable with four connectors. There are 4 cable "sections" X 4 connectors but it seems like it should read 1 X 4.

Sorry, meant to say "Is it number of cables times number of connectors, or number of connectors times number of cables?", not just say the same thing twice in a row.

Yeah, this is great, but where is the SF750!?!
Let's get some sweet overkill, pre-production PSUs in for testing. I want to see a dual-EPS, SFX test system benchmarked.
