Lets stick to THIS thread about which PSU to get ok?
Calculators give really high numbers to cover themselves for junk PSU. The CS/CX/VS is Corsair's budget line. Nothing fancy, but will get the job done. From your parts list I don't see any reason to get a massive 650W PSU. Any QUALITY psu from 450-550W will work fine. I run an i7 and a 200-225W PSU on a 450W PSU. And your setup should need less juice than mine. I'd look for a good 500-550, no need for a 650W.
Right, sorry. I'm still getting used to this website. Thank you for your info. My current PSU isn't that great, this is the one I have: https://www.amazon.co.uk/gp/product/B00H33SFJU?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00.
While gaming, I recently had an issue where my pc would crash and all my screens would go black, and the sound in-game would loop continuously. I would then need to switch my pc off and on again to fix the issue. My initial thought was that it was some sort of graphics card problem or memory problem, but after reading some threads online some said it may be something to do with the PSU not giving enough power to the components, hence why I've been doing PSU calculations (copied and pasted from another one of my replies).
Do you have any recommendations? My budget is around £50-£75 max.
