## Description

Buy

Review: Does the job - What can I say it's a Corsair no issues what so ever at the moment. Great and plenty of cables.
Review: Perfect purchase - This is my best purchase in ages, it is completely silent even when testing msi 4070graphics with Benchmark. Side cabling is a priceless idea and installation is a real pleasure compared to front cabling. I highly recommend it, it's worth spending a few pounds more. As for the shipment, it came in perfect condition, the cables were never opened in their plastic packaging. The mounting screws and cable ties are another nice touch. I'm delighted..
