PSU for oc on both ryzen 5 1600 and gtx 1070

[PhantomR]

Hey everyone,

I would like an advice: would a 550W PSU (like the Corsair RM550X) be enough for overclocking BOTH a Ryzen 5 1600 and an Asus gtx 1070 Turbo? Also, how would this do (http://www.bequiet.com/en/powersupply/754)? I currently have the latter, but can get a refund and get another within the next ~9 days.

Yes, a good quality 550w PSU would be good enough to support your system, however it would be the bare minimum ans I do not recommend that you go any lower.
I suggest you even opt for a 600w-700w PSU to leave you some breathing room if you want to install another 1070 in the future or install a water cooling kit.

So, if you have a Ryzen 1600 and a 1070, both overclocked, with around 5 case fans and 3 HDDs you can get away with 550w.
However, if you want to have any more than those things youd need a 600w+.
Your existing PSU @500w wouldnt really be able to run your new GPU and CPU, let alone leave you room to overclock.

I hope this helps, good luck.

I would stick to your Corsair. It's a very good quality PSU for money (unlike the CS and CX series, never buy those), and it has a 7 year warranty. Bequiet! only guarantees their PSU for 3 years. Furthermore, 550 Watts should be more than sufficient for that setup, as long as you aren't overvolting the CPU to extreme levels (that usually requires a custom cooling solution). At a 65 Watt TDP for the CPU and a 150 Watt TDP for the GPU, you can't really go wrong with 550 Watts. My estimate is that your system, under load at stock speeds, will be drawing around 300-350 Watts. That leaves 200 Watts of wiggle room for overlocking, though you'll definitely never use that much.

But as MART3R said, if you plan on using SLI, which I don't recommend because of stuttering, scaling, and compatibility issues (though that doesn't apply if it's for VR SLI, so if that's your purpose, it isn't a bad idea), you will need a higher power PSU if you continue to overclock the system.

Thank you very much to both of you. Would like to clarify that my current psu is the be quiet . Also, is there no chance I would also be able to use water cooling with 550w?

Another option would be the EVGA supernova g2 550w. Also the 650w supernova g3, but I read that the G3s are kind of noisy (idk about the 650w for sure). Also, the 650w is more expensive..wouldn't really like to go for more watts if lesser are ok for less price.

500w is not enough for a for a 1600 and a 1070.
550w is enough but not at the same time as water cooling.
600w will support both components and water cooling but not SLI 1070s.
650w will support all of the above.

Its never a good idea to cheap out on a PSU, always buy a good quality one or you could end up paying much much more in the longrun.
Im glad I could answer your questions, good luck.
