Is my PSU compatible with a GTX 1080?

curtisbain95 · Mar 9, 2018

Complete begginer here, I bought a pre-built PC a couple of years back and am looking to upgrade, it's currently a mini ITX build with a Mini 970 requiring 1 six pin or one 6+2 connector, I'm not entirely certain. I'm just wandering if the Corsair VS650 power supply has the right cabling for a GTX 1080? I have a bigger case now to provide room for a full size, however lack the knowledge to determine whether or not my PSU will be sufficient! Thanks in advance

yep it does but its a low quality corsair one. (say vs their RM series or HX, AX)
For $50 its a bargain for a seasonic s12 ii 620w.

The problem with low quality PSUs is that hey can fry other equipment if they go bust. its a gamble

According to Corsair it has 2x PCIe (6+2 pins) connectors:

The GTX1080 has one 8 pin power port, so you have the right cables.

Be sure to run your system through a power supply calculator to make sure 650 watts is enough:

Thanks for the swift response, is my vs650 a realistic risk? my output on a tdp calculator is 468 watts with a 1080 at full clocks. Would there be a likely event of it failing? Or are you saying better quality power supplies less vindictive when dying? haha

NO WAY would I ever recommend one use a Corsair VS with a GTX 1080 or any other high end GPU, just not worth the risk to cheap out on the PSU.

A higher quality PSU will have better protection built in so there is a smaller chance of taking out other components if it fails. Plus a higher quality PSU is more likely to actually output the wattage it advertises. Over time, PSUs will produce less wattage as they age.

Thanks man, would you reccommend a tier 1-2? Do you know if any relatively cheaper 650W tier 1-2's you can vouch for?

curtisbain95 · Mar 9, 2018

Can anyone reccommend me the best 650W PSU out there? So I can get a guess on a price range? Not looking to spend £80+ really, but if I have too I will! Thanks, keep in mind I have an MINI atx build, not sure if PSU's vary in model sizes or are universal, thanks again!

I would only use a Tier 1 or 2 PSU with an expensive GPU. I bought a Seasonic G450 about a year ago. I am not sure if they make a 650watt version in that series. I think the Seasonic s12 ii 620watt would be a good fit for you as recommended above. Anything from Seasonic, EVGA, or Corsair in Tier 1 or 2 would be acceptable.

jankerson · Mar 9, 2018

Yes Seasonic makes a G650W.

The Seasonic Focus Plus 650W.

Corsair RMX 650W

EVGA G3 650W.

Went for the seasonic s12 II in the end thanks for all the help lads! Much appreciated! Side note... anyone want to buy a pre-owned Corsair vs650

mjslakeridge · Mar 9, 2018

If I were in the market for a paper weight or a door stop, I would make you an offer on the Corsair, but I have a few doorstops here myself from old builds.
