Well reviewed PSU, overpowered for most, cheap at this price for those that need it.
Good deal if you have stock near you.

Also available RM1000x @ £125.99 maplin.co.uk/p/c…3uu

Product overview• 850W of continuous power gives you substantial headroom for overclocking, running multiple graphics cards and future upgrades
• ATX form factor allows the power supply to be connected to almost any motherboard and fits in most standard cases
• Fully modular design means you only use only the cables you require for easy builds with the best airflow
• Produces 22dBA at full load for an almost silent computing experience
• 89% efficient with a 80 PLUS gold rating, providing you with an extremely efficient power supply
• Manufacturer part number: CP-9020093-UK

Special features
• Zero RPM fan mode supplies you with near silence under light loads thanks to the built-in thermal sensor

What can I run from this power supply?
This 850W power supply (PSU) would be a perfect addition to a computer system that has overclocked components and multiple graphics card (in SLI or CrossFire) as well as a number of other components such as fans and lights. The power supply has been built with all Japanese 105°C capacitors, which helps to ensure solid power delivery and long term reliability. Underlining this power supply’s reliability, it comes with a seven year warranty. The RM850x is extremely efficient and runs quietly even when at full load, which is great for builds that you want to keep quiet. Future upgrades won't be a problem either – you'll be able to add more components or upgrade to more energy hungry ones without a problem.

How quiet and efficient is this power supply?
80 PLUS gold certified, this power supply is roughly 89% efficient under various loads. This means that almost 11% of electrical energy pulled will be wasted as excess heat, which also means that you'll have a reduced operating cost. At full load this power supply will only produce 22dBA of noise, so any noise produced is almost inaudible. What's more, this power supply has a zero RPM fan mode, where the fan doesn't operate at low to medium loads. The built-in thermal sensor will automatically control the fan when the cooling is need, providing you with virtually silent operation.

I would buy from Amazon (or Amazon Warehouse) for a better all round deal personally. Good power supplies though. The ‘i’ versions are quite handy as they have monitoring if you can get them.

I have the 850i and the app never recognises the PSU in the Corsair app, tried it on two different motherboards, PSU is really good though, cant fault that.

Across all systems I have about 8 ‘i’ PSUs (mostly RM and HX series) and never had an issue. Really only use it for power consumption monitoring and making sure voltages are in check - I heard some complaints before but I’ve never had any problems with it, think it’s worthwhile now even if the ‘x’ models are cheaper.
GOT THE RM1000I @£89 from scan 1 year ago, refurbished version but by experience is all new, just less warranty. super PSU's
always handy to buy above the power level you need as they tend to be more efficient and can output more power without spinning up their fans than if you bought a lower wattage supply that needs to work itself more to produce the same amount of power
Had a few corsairs over the years, always great PSUs, have a TX850 which is great, bought a RM850i recently for another build but due to coil whine issues went back...twice, instead went for a Seasonic Prime 850, very happy.
