Tier 3 (or 4) PSU for High end gaming system?

[Geral]

Hello community!

Ive been trying to build my own high end gaming system and i figure the PSU is just as important (if not more) as the other components.

The system will look something like this:

Motherboard: Maximus VII Formula
GPU: GTX 980
CPU: i7 4790k
RAM: 16GB (Most likely Corsair Dominator as it is the one i can find)
It will have an SSD and a HDD for storage.

The questions are:

1. First, how much wattage u think ill need? i was thinking 850w or more right?
2. Where i live (La Paz, Bolivia, Southamerica), all i can find is tier 3 or 4 psu's (according to the tier list on the site ofc)

The ones i can find are:

• 
  ■ Deepcool Quanta 750w 1000w 1200w Channel Well Technology (tier 3) (i can find the 1000w)
  ■ Thermaltake Smart / Smart M Channel Well Technology (Tier 4)

Would it be better to buy online for what im planning to do? what if i dont overclock too much, would those psu's would be enough?.

3. If i order the products online, wich one will you recommend? i was thinking in two:

• 
  ■ Corsair AX1500i
  ■ Evga Supernova T2

anyother you recommend?

Evga Supernova G2

from online--corsair ax760i

why would you need a corsair ax1500i to run that?

1. You could run that system on a quality 500 watt power supply (single 980 GPU). 850 is overkill. So you don't need to be looking for a 1000w PSU. I would look at 750 / 850s as they are fairly common, and if you later choose to add a second GPU you can. With this in mind do you get better options if you look at smaller power supplies?

Pick a high rated PSU that can provide +100w to +150w for best stability. Personally I like the Strider series PSU's.

no better psu's even if lower wattage. All i can find is Tier 3 psu's here. I could find the evga supernova 750w (the one in the tier 3) if that is of anyhelp.

So with that in mind, and IF the best option is to buy online, i was thinking to buy some big ass psu for the future, so if i want to add more components i wont have to buy another psu again (and buy it online... again).

For a high end gaming rig you need to stick with a tier 1 or 2 unit. 550w is plenty for what you have listed, 750-850w if you plan on a 2nd 980 for SLI.

you dont need big bad ass for the future

the ax760i will still give you future proofing

or if you really want get the ax860i

both those carry a 7 year warranty

Solutions like the AX1500 are more intended for quad SLI workstations or with dual Xeon processors. I'm talking like quad Titans or Quadro 6000s that have to support 8 RAM slots and massive raid configurations.

You loose a little bit of voltage regulation overshooting your power needs too far. Just because the drive went further than everyone else on the course, if your not on the green you still missed.

System Power Supply Requirements for a single GeForce GTX 980
• NVIDIA specifies a minimum of a 500 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 38 Amps or greater
• the system power supply should also have at least two 75-Watt 6-pin PCI Express supplementary power connectors. There are some non-reference design cards that require one 75-Watt 6-pin and one 150-Watt 8-pin PCI Express supplementary power connectors or two 150-Watt 8-pin PCI Express supplementary power connectors.

System Power Supply Requirements for two NVIDIA Reference Design GeForce GTX 980 graphics cards in 2-way SLI mode
• NVIDIA specifies a minimum of a 750 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 60 Amps or greater
• the system power supply should also have at least four 75-Watt 6-pin PCI Express supplementary power connectors. There are some non-reference design cards that require one 75-Watt 6-pin and one 150-Watt 8-pin PCI Express supplementary power connectors or two 150-Watt 8-pin PCI Express supplementary power connectors per card.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.
Deepcool Quanta DQ750
• OEM: CWT (Channel Well Technology) PUQ(G) Platform
• maximum combined +12 Volt continuous current rating: 62 Amps <===== Sufficient for 2-way SLI
• four 150-Watt (6+2)-pin PCI Express supplementary power connectors <===== Sufficient for 2-way SLI
• Semi-Modular Output Cables: Yes
• Official Intel Haswell Compliance: Yes
• 80 PLUS GOLD Efficiency Certification
• 5 Year Limited Warranty

Ok thanks guys for the reference. 750-850w will be what ill aim for.
Wich brand and model will you advise?. Seems like everyone tells me to go for a corsair.

Thanks for the detailed answer. I didnt see the Deepcool Quanta 750 on my country, but i did see the 1000w version wich will work just as well as you point out. Both of them are on the Tier 3 (On the PSU tier on this site), and everyone seems to be saying not to get any Tier 3 PSU for this build, why would you say its ok to buy it? i mean, it would be easier for me to do so.

I don't need a tier list to tell me what is a good or bad PSU.

There are obvious inconsistencies in the tier list. Generalization of the Deepcool Quanta Series is just wrong since all of the models in the series don't have the same component quality or have the same conversion efficiency.

The Deepcool Quanta DQ1000 uses a Japanese Panasonic 680µF, 400V, 105°C bulk capacitor on its primary and Japanese Nippon Chemi-Con KZE Series 105°C capacitors on its secondary. All voltages and ripple suppression remain well within ATX12V specs. Its closest to a Corsair HX1050.

Ok thanks!, regrettably i do need i list to tell me what is good PSU.

As for what you say, it seems a good option then. I can buy that one here and it will be cheaper than to buy one online.

But will it be enough for my needs? Dont forget i plan to overclock.
How does the community feels about that Deepcool Quanta 1000w?

You are all wellcome to answer please.

1000 Watts is way more than you need even if you overclock both the CPU and GPUs.
