So I have a Corsair VS550 550W Bulk Edition, i5 6600k and Im planning on getting a GTX 1080 but I dont know if my PSU can handle it.


I have done some research and what Ive gotten is that the PSU is very cheap and wont handle it and that it should handle it just fine. Any response gladly taken.

The VS550 has enough power for the GTX 1080; but like you've heard it is low quality and would only be a matter of time before it failed, possibly causing damage to other components including your GPU. It's best to get a better quality PSU for your expensive GPU.

The Corsair CX 550 or 650 (2017) would be okay. These are still budget units, but they are safer and better quality than the VS. Sometimes you can find even better units for around the same price though.
The best deal on a good quality PSU right now is this.
Power Supply: EVGA - SuperNOVA G3 550W 80+ Gold Certified Fully-Modular ATX Power Supply ($59.99 @ Amazon)
*Update: Actually, after following the link to the actual reseller page, that isn't the same price anymore. Here's the next best thing I could find. https://www.amazon.com/dp/B077916ZZV/?tag=pcpapi-20

Thanks! Sounds good, hopefully my budget can cut it considering many seem to want to charge 30 bucks for shipping.

well to just to add the PSU is best on 50% power so for example i have 1080ti gameing and i test how much watts is my build spending my build spend 450 watts on full load so i say your is a bit less so i recommend u get the one that volkren recommend but get the 650w it is better cos as i sayd PSU work best on 50% load :D

Technically it is meant to me 0.707 of max (iirc), from something I learnt all them years ago doing electronics, which is basically 70% is the max you should run things.

50% load capacity will have the best efficiency; the least amount of wasted energy.

That can be true, but there is a website that shows you how many years it takes to get back the 1-2% effiency over cost and a lot of the time it is about 6 years. If I find that website I will add it to this post.

Valid point. The cost savings are not much and not really a concern unless it is a 24/7 full load type of situation.

No way would I ever hook up a GTX 1080 or any high end GPU to a Corsair VS PSU.

You really need to replace it with a good unit.
