Corsair®, the most awarded PC power supply brand in the world, today announced the new line of CS Series Modular power supplies (PSUs) in 450, 550, 650 and 750 watt models. Designed to be exceptionally energy efficient and simple to install, the new CS Series are the most affordable 80 PLUS® Gold certified PSUs in Corsair’s line of high-performance PC components.

The CS Series Modular PSUs are designed to deliver stable, continuous power with 80 PLUS Gold certified power efficiency to minimize energy waste and lower electrical bills. The new PSUs are cooled with a 120mm sleeve bearing fan that runs at low speeds during typical loads, keeping the PSU nearly silent during everyday tasks. The CS Series meet the latest ATX power specifications and are compatible with the latest AMD and Intel® processors, with full support for the low-power modes of the latest 4th Generation Intel Core® processors.

The CS Series PSUs feature a semi-modular cable system with the core motherboard power cables (24 pin and 8 pin EPS12V) permanently attached and include modular flat cables that can be attached for powering other devices such as graphics cards, SSDs, hard drives, and fans. The modular design enables users to add just the cables required for their PC, which combined with the black flat cables, creates PCs with reduced cable clutter, a cleaner look, and better airflow.
 
Too bad they start at 450 watts. There's almost nothing available for low power high efficiency power supplies.

Unless you are using a high end video card, 450 watts is way more than needed, and the efficiency at <100 watts on these high wattage power supplies is generally not that good.

My HTPC draws around 40 watts under normal usage, and that's with a couple 2TB drives installed. I ended up buying a 380 watt power supply because it was the lowest wattage 80 plus supply I could find at the time. Woudl have been happier with a 150-200 watt supply, but anything in that wattage range was low quality/efficiency.
 
It's just not that cost effective to make PSUs that are that low wattage. You essentially end up with a lower wattage for the same cost as the higher wattage unit.

As for efficiency at <100W, Ecova is actually certifying PSUs with 10% efficiency as well since 4/2012. Also, a lot of reviewers test at 10% load as well. You'll find that the efficiency of a good 450W at 45W is not really that bad. Often well over 80%.
 
I wanna know the OEM and if it uses LTec caps like the RM.

Edit: WTF GREATWALL?!

Jonny, you gonna have a review of this anytime soon?
 
I wish Corsair would sell a set of cables that is really short for small form factor Pcs.
The only reason I didn't use a Corsair or Seasonic in my Htpc is because I found a few models that had cable sets specifically made for very small cases, without requiring modifications or extreme cable management.

Why "WTF GREATWALL?!"?

Review samples are floating around. I suspect in two to three weeks we should see some reviews pop up.

Right now, our PSU review queue is backed up. Jeremy just finished up doing the RM Series this week while everyone else had their reviews published a month ago. :p
 
We should have one (or more) of these as well at some point in the future.

Well, maybe not everyone........... ;)
