hi, i have a corsair cx 500 watt power supply, can it run a EVGA GeForce GTX 1080 FTW GAMING ACX 3.0?

what's the rest of the system? that card can hit 250w in a gaming load so you may need some more power even at stock speeds.

It may run it for awhile but the CX has a bad track record, especially at high loads. I personally wouldn't trust a cheap lower quality PSU to power a $650 video card.

bignastyid :

in the specs page it says that it requires 500 watt or greater, should i buy a new one?, if so what should i buy?

rashid_4ever :

It's not just about advertised wattage. Many low quality PSUs flat out lie or push extra power to the lesser used 3.3 and 5v rails and have a weak 12v rail which is the most important rail in a modern system. Other lower quality units like your CX can deliver their advertised wattage, but use cheap capacitors that cant handle heat or high loads well and will usually fail early. For a gaming rig with a GTX 1080 you want a tier 1 or 2 PSU http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html. I'd go atleast 550w.

Math Geek · Jul 11, 2016

i would, your pushing over 400w with that set-up easily. the cx 500 won't like doing that for very long.

this would be a decent choice that won't break the bank http://pcpartpicker.com/product/8RvZxr/evga-bq-650w-80-bronze-certified-semi-modular-atx-power-supply-110-bq-0650-v1
