Power ratings are continuous, not peak, for superior protection for your valuable PC. Corsair uses high-quality internal components, and the RM1000 is guaranteed to deliver clean, stable, continuous power.

About Corsair Power Supplies

Corsair is the best-selling brand of enthusiast power supplies worldwide, and offers more power supplies with seven-year warranties than any other major brand. Corsair innovations, like the first DSP-controlled desktop PC power supply, drive our focus on providing reliable, quiet and efficient PSUs for everything from basic desktop systems to one-of-a-kind dream PCs.

High-quality, low-noise capacitors and transformers

RM Series power supplies are designed with capacitors and transformers carefully selected to eliminate coil whine and other background noise that can be annoying in quiet environments.

Zero RPM Fan Mode

The efficient design of the RM1000 means minimal excess heat generation, so the fan doesn't even need to spin under low to medium loads. And when you're pushing it hard, the thermal sensor controls the fan speed to ensure that it gets the cooling it needs without any extra noise.

    Virtually silent and FULLY modular., September 25, 2013
    Eric Jacobson (Portland, Oregon) –

    Verified Purchase(What’s this?)
    The Corsair RM Series is absolutely outstanding from its 80-Plus certification to its CONTINUOUS power ratings to its nearly silent operation plus it truly is fully modular.


    The RM series doesn’t turn on the fan as long as the computer is using less than 40% of the power output. This means, unless you’re beating the heck out of your machine with Maya 3-D modeling or using the entire Adobe Creative Suite at the same time, you will hear NO NOISE from your power supply. I selected this power supply for a whisper-silent build using a NZXT H630 Case, Nexus fans, and a Cooler Master Hyper 212 CPU cooler along with SSDs, so I wanted quiet. The RM series does not disappoint.


    When you’re selecting a power supply, it is absolutely CRITICAL that you select a supply with a CONTINUOUS power rating, not a PEAK power rating. Continuous means the power supply delivers its power rating the entire time it’s on with no dipping. Peak power ratings mean that the power supply can hit that power rating briefly, but cannot sustain that power delivery. If you’re talking about gaming video cards and/or running lots of drives, you want continuous power. 80-Plus certification means the power supply runs efficiently, doing the best it can to use as little power as necessary so your utility bills don’t skyrocket.


    I’ve been using “modular” power supplies for a few years now, and I’ve discovered that modular can mean different things to different manufacturers. Some manufacturers believe that modular means that the accessory plugs can be added and taken away, but your main cables such as mobo power and at least one 6-pin power rail are going to permanently attached to the power supply. Not so with the Corsair RM series. You can pick and choose exactly what you want to run off the power supply.

    Why is this a big benefit? For the majority of users, it’s not. Sure, it’s cool to fully customize your power supply, but if it’s the only PSU in the box, you’ll want to run the mobo power cables, for sure. Where fully modular PSUs are neat is in options: imagine you want to run a triple or quad SLI/Crossfire rig with four SSDs in RAID with four 3TB/4TB HDDs for data? You’re going to need a TON of power, possibly more than a single power supply can deliver, but, you won’t need two power supplies delivering power to the mobo. Now, you can run two PSUs with only one delivering power to the mobo while the other delivers power to all the HDDs, for example.


    The Corsair RM Series is quite possibly the best solution on the market currently for power users who don’t want to sacrifice silence for performance. The RM series truly gives the best of all worlds by offering quiet, consistent power at a truly reasonable price.

    Very Quiet, October 16, 2013

    Verified Purchase(What’s this?)
    Quiet, affordable and fully modular. Only thing I don’t like about it are the pci-e cables. I ripped mine apart to sleeve so it wasn’t a big deal, but with my 670 gpu the connectors would have been hard to seat without having done so (one pin up one down on this gpu, and the cables provided seem to be intended for two up/two down)

    Silent operation, high efficiency, great performance under full-load. What more can I ask for?, October 1, 2013

    This review is for the 750Watt model, I’ve purchased on Newegg.

    Built quality and style:
    Built like a tank! Well-designed body and 140mm black fan grill with solid metal housing. The paint job is top notch, textured matt black, with subtle yellow & white markings. Fan blade color in grey. will look very good with darker types of case and mobo setups. The side edge of the PSU are angled so that they’re not sharp. The RM750 felt like a solid piece of equipment out of box. The PSU profile is not oversized- pretty much fit right into my micro atx gaming rig.

    Come with c-link cable, mobo (24-pin), cpu (8-pin), molex (3 connectors), molex (4 connectors), two pci-e (6+2 pin dual connectors), two sata (4 connectors), two molex to 4-pin fan adapters. (All cables are flat and comes with text labels)

    Noise Level:
    One thing that really amazes me is the noise level: I can run the computer most of the time without the RM750 fan ever turning on! The PSU will go “ninja-mode” when under 40% load. and whenever I’m gaming, during full load, the unit’s fan is still very quiet.

    Will fit any PC setup, Silent operation if you want to build a HTPC. Quiet operation if you are running 3d games. 80-plus gold certified efficiency. All cables are FULLY detachable, including the ATX 24-pin! You can really achieve a clean look (if you have a windowed PC) and clutter-free setup that will help increase airflow inside the case. Flat cables are a plus as they are better for cable management in case if you want to hide them behind the mobo tray.
