Will Corsair HX850 work for new build with Skylake and 970?

benzo7 · Aug 14, 2015

I'm putting together a build with a 6700k and a Gigabyte 970 GTX G1, but am wondering if my PSU from an old build with work. It's a Corsair HX850 gold

Any thoughts on whether this slightly dated PSU with work for my new build. Let me know if knowing the other components would help.

Thanks!

Yes, the same connectors are still being used so the power supply will work just fine.

850w may be too much for your build... it's a gold certified psu, it is very efficient. You may want to consider the Antec Edge 650W fully modular 80+ gold certified.

In the case you want to add a second gpu to it some time later, then ignore what I said and stick to the hx850

You are good, the system will most likely consume less than 400w, so on top of having more than enough power, you are close to the most efficient point which is 50% load or 425w.

Thanks for the replies. Yeah, I know the 850 is overkill for this build as it stands, but I do plan on getting another 970 at some point. Plus I already have this PSU on hand from a previous build so just trying to recycle where I can.

When I add another 970 though, would this 850 be able to deliver enough power?

If it's in good technical shape and into specs range, that PSU of yours will power up a 970SLI plus any CPU/MB/HDDs/SSDs/Fans you can throw at it.

Good to know! It was used for about 7 or 8 months or so in another build, but she's been sitting dormant for about a year. Is there a way to test its condition?

Well its possible to test the PSU for degrading but its difficult and expensive. Most psu comes with 5 years of warranty or more so I wouldnt be considered at all with its ability to perform. I have sli 970 on my evga 850w and I don't have any issues. It never gets close to that number on full load.
