630 Watt PSU enough to hold a i7 5820k + GTX 780?

THEINTUNITY · Sep 11, 2014

Hello people of the internet,

I'm about to do a platform upgrade this autumn, namely:

From an i5 3570k, asrock z77 extreme4 and corsair vengeance DDR3 - to an i7 5820k, ASRock X99 Extreme4 and the Adata XPG Z1.

At the moment I have a Be Quiet! Pure Power 630 watt power supply (bronze rated).
I also have a GTX 780 from Asus (with quite a beastly overclock)

The power draw on this i7 cpu is pretty enormous, same as on my gpu. I'm not really an expert on these kind of things, so I'm asking you guys, if my Power Supply is able to hold an i7 5820k and GTX 780 without burning up.

And if so...would I be able to overclock both the cpu and the gpu?

Excuse me for my bad English.

Greets,

Vincent from the Netherlands

I would upgrade it's not the greatest quality power supply.

Is it a very old psu? A fairly new Pure Power CM L8 will be enough for your build.

PS. For strong overclock both the cpu and the gpu i agree w/ SR-71 Blackbird. This would be a good option:

Yes.

i7 5820k: ~140W
GTX 780: ~250W
Rest of the system: ~100W

Total power consumption at 100% load: 490W

Damn, I'm to short on money to get myself a new power supply aswell. I'll be fine without an overclock I guess. And the power supply Filippi is recommending me is in not the slightest way better than my power supply. not worth it to buy. My PSU isn't that old though, not even 2 years old.

Blaise170 · Sep 11, 2014

Actually that XFX is better than the one you have, but the Pure Power isn't awful. An upgrade wouldn't hurt though.

What he recommended is a few tiers above what you currently have. Check this out:

I think your current PSU can handle it, provided you keep everything on stock.

Hmm, it doesn't make me happy that I'm not able to overclock. I guess I'll keep everything on stock, and then upgrade my power supply in januari to something like Blackbird recommends. And then I'm gonna overclock THE SH** out of it. Thanks a lot for all your help and quick responses guys, if you have usefull tips or recommendations to make, I'm interested

Glad to assist!

Thanks for posting!

How about this? It has a nice 62 amps on the 12v rail, in america atleast, this unit is cheaper than the rest suggested http://www.amazon.com/EVGA-SuperNOVA-80PLUS-Certified-110-B2-0750-VR/dp/B00KFAFRW6/ref=sr_1_1?ie=UTF8&qid=undefined&sr=8-1&keywords=evga+750+b2
It also falls under tier 2s which is good.

Blaise170 · Sep 11, 2014

Rybo :

I hate that tier list, but in any case he lives in the Netherlands, not the US.

Dark Lord of Tech · Sep 11, 2014

I don't use a tier list myself , I don't agree with a lot of it.

NightAntilli · Sep 11, 2014

Generally, the tier list works well for the highest two tiers and the lowest tier. Anything in between can be debatable.

Dark Lord of Tech · Sep 11, 2014

I use my memory!

Rybo · Sep 11, 2014

Everyone should, unless they don't have previous experiences. :bounce:

Blaise170 · Sep 12, 2014

I use my memory and for more obscure manufacturers I use realhardtechx.com.

THEINTUNITY · Sep 13, 2014

I made a list of those quality power supplies you guys suggested, and will surely take a look if I can get one of those in januari, I will of course not buy from amazon since I live in the Netherlands, so some of these will not be available at alternate which is the shop im buying at.

I really like the people here on tomshardware for their support and quick responses,

Case closed, and again....

Thanks a lot!
