Corsair Releases RM Series Power Supplies
by Ian Cutress on September 14, 2013 9:35 AM EST
Corsair sell a lot of components for PCs: memory, cases, SSDs, cooling, peripherals and power supplies to name their current lineup. For that last element, Corsair have released a new range of 'ultra-quiet' fully modular power supplies, dubbed the RM series. These PSUs replace the TX Series line while offering 80 PLUS Gold across the range, meaning a minimum energy efficiency at 87% for 20% load and 90% for 50% load (88%/92% respectively for 230V AC).
The RM series will have several models available from 450W up to 1000W. Each power supply offers a low noise Corsair NR135L fan plus a Zero RPM Fan mode (for low usage operation under 40% load), as well as low profile modular cables. Select models (such as the RM1000) come with a Corsair Digital Bridge cable and Corsair Link compatibility for real-time monitoring of fan speeds and power delivery. Each PSU comes with a five year warranty included and is Haswell compatible.

My 3960X + 660Ti kill a 450W "dynamic" power PSU. They make a 450W standard power supply cringe. Another video card? Will you pay for my house fire and replacement parts?IanCutress - Sunday, September 15, 2013 - link
For any GPU compute on big GPUs, you're in for a shock. For my OC'ed beast (dual CPU + 4x7970) I hit 1550W easily. For my daily (3960X + two 7950s) I can hit 650W with the right workload, which means I use something near a thousand.Buying power supplies is like buying a car and doing 70mph everywhere. If you buy the one that does 80mph, you'll be punishing the car driving near its top speed. Buy a car that does 150mph, and 70mph is a walk in the park.
I know what you mean though - I can run a 5970+5870 bitcoin miner on a 500W PSU without issue, and it'll work day in day out, and I get a warranty. Though as it's never going to see a workload spike, it's not an issue there

Yep, you must be right. I guess there isn't a market for these PSUs and that's why the companies launch them - they want to squander their resources and have no clue of what the market wants or needs. I admit I'm not in the main stream, but there are people who would like to see even more powerful and efficient PSUs than these - those who run dual CPUs and multiple GPUs on the same motherboard. I'd like to find a fully modular, really quiet 1800W+ PSU that is 80 Plus Titanium so that I can add a fourth GPU for rendering.bobbozzo - Sunday, September 15, 2013 - link
20A circuits are so rare in the US that is is extremely unlikely anyone is going to offer a consumer PSU over 1500W.DanNeely - Monday, September 16, 2013 - link
IIRC 20A circuits are required in the latest code for in the kitchen; although they're still uncommon outside of it. I think the bigger issue is that a 20A outlet/device requires a different plug than the standard 15A model. As a result to be in code an 1800W PSU in the us would need to come with a cable that couldn't be plugged into normal outlets. The returns from can't be bothered to read the box idiots from it would be prohibitively high.DanNeely - Monday, September 16, 2013 - link
If you need more than 1500W now you'll need to go dual PSU. You can buy supplemental units that fit into a 5.25" bay; or use two standard PSUs with a control cable to have them both turn on at the same time (a 24pin pass through that connects the power on signals to the second PSU as well). The main caveat is that you'll need to either upgrade your breaker and wiring to support 20A+ or to plug the second PSU to a different circuit.http://www.newegg.com/Product/Product.aspx?Item=N8...

I tripped the overload on my Antec 750w the other day with a 2500K @ 4.7ghz and 2 x 7970 reference cards.nevertell - Saturday, September 14, 2013 - link

Clever! Took me a second but all of a sudden it was "I see what you did there"bobbozzo - Saturday, September 14, 2013 - link
Hi, do you know who the OEM is?
