Hi so my psu is an Corsair cx650m 80plus bronze, it’s brand new I only bought it 2 weeks ago, the problem is it makes coil whines but most say its common on these type of modules. So I’m buying a new gtx 780 ti super clocked version 4 gb gddr5 on eBay, but will my psu be enough for it even underload cause for psu recommendations you need at least 550 watt psu.
