Which PSU for this build?

[Hakiroto]

Hey, everyone,

 

I'll be building a new gaming system in a couple of weeks but I still haven't decided on the PSU. I like the look of the EVGA G2 (as it seems to get great reviews) but I'm not sure if I should go for the 750W (118€) or 850W (171€). Cheaper is obviously better but I don't want to scrimp on something as important as the PSU. My system will be as follows. From what I know, even a 750W will be more than enough but some opinions and/or some advice would be very welcome.

• i7-6700K
• H110i GTX
• MSI 980 Ti (or Zotac Amp! Extreme 980 Ti)
• Asus ROG Maximus VIII Hero
• Corsair Vengeance LPX 16GB
• 850 Evo 500GB
• Define R5

As always, thank you in advance!

Are you planning to do a SLI configuration in the future? If not, then go for the EVGA SuperNova G2 550W. If you're planning to do an SLI configuration go for an Corsair RM850i.

Any brand that's 600 w should be safe.

^ To be honest, I'm not planing far enough ahead to consider an SLI configuration. I imagine I'll OC the CPU as I know I'll have good enough cooling and a solid board but I don't know yet if I'll one day drop another 980 Ti in there. If I did, what kind of power would I be needing? Thanks.

^ So generally 600W will be fine if I stick with a single 980 Ti (and CPU OC)?

Like I said. If you aren't planning to do a SLI configuration go for the EVGA SuperNova G2 550W. But if you do plan on an SLI configuration I would go for an Corsair RM850i (850 Watt).

I would take a EVGA 650w G2/GS or hte Corsair RM650x for 1 980ti but 550w would probably be fine.

For 2 cards 750w would probably be enough and that price scaling is pretty bad (from 750w to 850w).

Get a 650w G2 by EVGA if it's cheaper than the 750w, since you won't need the extra watts even for overclocking.

 

I would not recommend a Corsair RM series PSU if it's more expensive than the EVGA G2, since generally the RM series is over priced. Good PSU's, too expensive.

the super flower leadex gold is a good series too

Why would he need an 650W power supply when he will have 100W left over with an 550W power supply?

To be safe! Before my (internet) friend changed his PSU, he had a 980 and a 4770k on 500w and his computer shut down every time he tried to run his OC at load (not enough power,) the OC worked fine after he upgraded.

Lol so you think when he overclocks is CPU and GPU it will shut down? The power supply i recommended is more than enough and is also 80+ Gold certified. I have 2x R9 290X wit han RM100 Watt PSU and that is even overkill

His computer did shut off, not might have.

 

Also, you're not everybody. Sure, you don't need 1000w to drive two R9 290Xs in Xfire, but that doesn't mean you know everything about power.

I've build enough computers to know how much power a computer needs. I wouldn't suggest a high power supply unless it's needed which in this case isn't. And i said "so you think Berlihm's computer will shutdown when he overclocks his CPU/GPU." Well I don't think you have enough knowledge about PSU's. I'm not trying to be mean, but don't go in to the fact that when a friends pc shuts down when he overclocked it it's the PSU's fault. I think he overclocked it to a higher clockspeed than the CPU and motherboard can handle and that's why the computer shuts down every time.

You should read my first post, the problem stopped after he changed out his PSU for a 600w B2. His old one wasn't horrible either, an old Seasonic PSU. He put it in a different computer.

Or he had an faulty PSU, he overclocked too high or he didn't know how much power is system uses. You didn't say that he putted the PSU in to another computer
