Is it a bit overkill?

[Dissitesuxba11s]

 

From this previous thread (see above), a user recommended that I can get a 80+ Platinum for the price that was going to spend on a Corsair RM650i. So I did some digging and I found the Corsair HX750 Platinum. They are priced regularly the same, US$119.99 but the HX750 has a mail-in rebate right now through Newegg. My question is, is a 750W PSU a bit overkill for my planned build? My updated parts list can be seen below. Note that this does not take into account the power draw by the pump, not sure about the fans.

 

The Build ---> https://pcpartpicker.com/list/6mp2cc

For those that don't want to click the link:

CPU: Ryzen 7 1700

Motherboard: Asus Crosshair VI Hero (Wi-fi AC)

Memory: G. Skill Trident Z RGB 16 GB (2X8) DDR4

Storage: Samsung 960 EVO 250 GB M.2-2280 SSD

Storage: Samsung 850 EVO 500 GB 2.5" SSD

Storage: WD Blue 3TB 2.5" 5400RPM HDD

GPU: GTX 1080 TI

Case: Corsair 760T White Full Tower

PSU: Corsair RM650i

Misc: EK-Coolstream PE 360 (Triple) Radiator

EK-Supremacy EVO AMD - Nickel CPU Block

D5 X-Res 100 CSQ Pump Combo

3 X Corsair Air Series SP120 Quiet Edition High Static Pressure 120 mm Fans

Rated Power: 444 W

 

And just for kicks, for SLI 1080 TI's, my rated power is 694W. Any input is appreciated. If you know of a better PSU, then feel free to suggest it. I based my decision on the Tier Lists by STRMfromXMN.

You don't need a Platinum PSU really. Stick with Corsair RM650i

[NumLock21]

750w overkill? Nope

[TrigrH]

Single GPU: 650w

Dual GPU: 850w

[vanished]

If by "overpowered" do you mean could you get by with 650, then yes.  But is it a problem, or massively excessive?  No, not really.

I use a single 1070 + 1600 and have a 750w EVGA Platinum unit so...nah.

 

PSUs are at their most efficient in the 50% load range and if you have more power than needed, they run quieter. Upgradability is a nice perk as well.

[Dissitesuxba11s]

So, if I get the HX850 Platinum now, with the idea of upgrading to SLI 1080 TI's in the future, then I am fine?

 

I did forget to mention, I am not immediately buying the 1080 TI, I will be using an EVGA GTX 980 Hydro Copper that my friend gave me until I can get the 1080 TI at a good deal. With the 980, PC Parts Picker is saying that the required power is at 395W.

[DarkSmith2]

these wattage evaluation from pcpartpicker doesnt include the d5 pump and doesnt include Overclocking. You won't probably use all your components at full load the same time. But if you would want to keep it efficient i would go straight for 850w just to be safe. 

 

1000w if you are planing to SLI the 1080ti.

[Dissitesuxba11s]

Now I am bit more confused. First the suggestion for SLI was 850W, now it is at 1000W!

[That_PC_Kid]

For your build a 750 Watt PSU is not overkill. You don't need 80+ Platinum though. 80+ Gold is enough nowadays. I'd suggest an EVGA SuperNOVA G3 750W for $117.30 with free shipping on Amazon.

An 850W Psu would be O.K whit SLI and O.C but a 1000W would be best for silence and

efficiency.

Ok, that makes sense. Especially since I am not really sure if I will even do SLI. Just making sure I am ready for if I do.

Yes, unless you are doing very heavy overclocking on them.

True. There is only about 2-3% efficiency increase.

i honestly wouldnt buy a 1080ti anymore. If you put a 980ti in, it should last until volta release

I thought Volta (and Tesla for that matter), was more geared towards data centers, and not consumers?

There also will be consumer cards approximatley early in 2018. So about of the half of the "premium performance time" of the card is about to end. Ti cards are always godlike for a year until the "xx70" will hit or overcome its performance for a cheaper price.

 

You basically have a cycle where its worth buying a GPU. Every 2years you get a new release of a Ti card. But you are also getting a new set of the lower end cards every two years. So next year we'll see "XX70" Volta cards which will most likely need less power for the same or a little more performance of the current 1080ti. And if you are not in the need of buying a card because you own a 980ti its basically like burning money to buy a 1080ti 5month after its release. (or even later because you said you'll buy it later).

 

But if you actually do need the performance of the 1080ti as fast as possible you can buy it with no regrets. I actually dont know what you are planning to do with your rig but for me i would always try to get into the cheaper card cycle, instead of paying the premium for a "premium performance year".

Wow, I didn't know about how the release cycle of GPU's works. Now I know. I am not in a hurry to upgrade to a high end GPU just yet so I might take your advice and wait. If these new cards will most likely need less power at a performance comparable if not better than the 1080 TI, then getting a 850W might be my safe bet for now even with possible SLI planned in the future.

 

Side note: I am building this rig so that I can teach myself how to code and CAD, and some play some games.
