A NewEgg Tale: The 3 PSUs

[elijahsearle]

I'm building my first computer and just got the case and fans.

I know all the parts I want to buy except for the mobo (2 choices) and PSU.
Neweggg has a deal on 3 PSUs and I can't decide which one, so I would appreciate your input!

Let's start with my current parts.
Case: Haf x
CPU: i5 3570k (OC to around 4.2, if I can)
GPU: EVGA GTX 670 FTW 2GB (may overclock waay in the future)
Mobo: Asus Sabertooth Z77 (let's assume that)
RAM: G. Skill Sniper 1.25v 4x4GB, or Corsair Vengeance 4x4gb 1.35v
SSD: Samsung 830 128GB
Optical Drive: Asus 24x DVD/CD burner.
Water Cooling Kit: XSPC RX360 kit (externally mounted)

In the future I would like to add a second GPU in SLI (in a year or two) and another, larger SSD.

All that said, using the thermaltake and newegg PSU calculators, they roughly gave me 850w with my future upgrades included.

So here are the PSU's, with links.
Cooler Master Silent Pro 1000w 80plus Bronze $139.99 after $20 rebate.

Seasonic X750 750w 80plus Gold, Modular $119.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087

Corsair TX 850 850w Enthusiast Series 80plus Bronze $104.99 after $20 rebate
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139022&nm_mc=EMC-IGNEFL071312&cm_mmc=EMC-IGNEFL071312-_-EMC-071312-Index-_-PowerSupplies-_-17139022-L04D

So, I don't really mind buying another PSU in the future, but I'd prefer not having to. What I really care about is having enough power, heat/effeciency and somewhat it's quietness.
What do you think?
Also! Would it be possible to plug my fans/case fans straight into these PSUs so I can start working on my air flow?

cooler master is your only real choice there. The 750 wont be enough for sli and overclocked, and the 850 doesnt leave you much headroom.

yes you can connect the fans directly to the psu to test them. I hope you know how to turn on the psu without a motherboard being attached. LoL

 

[rocknrollz]

The x750 is plenty. Your setup barley takes 400W. SLI would take almost 600W. 750 is plenty, and the X series from seasonic is the best PSU series available. (AX series from corsair is awesome too)

 

[Deleted member 217926]

Huh? GTX 670 Sli needs a manufacturer recommended 750w power supply. That always assumes a "generic" model. The Seasonic and the Corsair are both very high quality. The Coolermaster is a Coolermaster.

http://www.realhardtechx.com/index_archivos/Page362.htm

Either the X750 or the 850TX would be fine for a 2 x GTX 670 system. For $119 the X750 is an amazing deal. It's one of the best power supplies made.

 

[rocknrollz]

Now that I look at it, the 670 requires 30A on the +12V line. The x750 provides 62A, so 670 SLI should work. Although, it may be cutting it close.

 

[Deleted member 217926]

Yes, a system with a GTX 670 needs a minimum 500w / 30a power supply. The second card does not require another 30 amps though since the first 30 amps include the whole computer. A GTX 670 consumes around 15 amps by itself.

 

[Silvune]

A GTX 670 does not draw (30x12) 360W. 30A is for a whole system with a GTX 670.

+1 to the Seasonic X750.

 

[elijahsearle]

So the Seasonic x750 would be enough for the sli, got it. But including the water cooling 750 pump, sli and the 2 ssd's and overclocking the CPU, is it still enough? The reviews I've read of the Seasonic are great. I just want to be absolutely sure I don't push it.

 

[Deleted member 217926]

This?

Draws 23 watts. SSDs use about 5 watts each. Don't RAID SSDs if that's what you are planning. The only place you will see a difference is in synthetic benchmarks and you lose TRIM. A single larger SSD is better.

The Seasonic is fine. You are not pushing it at all.

 

[elijahsearle]

So, I just re-did my "future" setup on thermaltake and extreme lite's PSU calculator. And um...boy did I mess up my original one. I used 4 CPUs, thinking it meant cores. On my last go, using 2 gtx 680's (since there is no 670) my recommended wattage was about 670. I'm not sure if the overclock I put in will "work" or if it was added to that total.

But are those PSU calculators fairly correct?

 

[Deleted member 217926]

They generally overestimate by quite a bit. They assume you are buying a junk power supply.

 

[Temile]

PSU calculators significantly overstate your needs. I think it is an honest attempt to deal with bad psus that don't put out what they rated for; considering the unlikely possibility that every single components runs simultaneously at highest power; and trying to provide some leeway because not everything is the same (one gpu may draw more power than another from a different manufacturer for example).

 

[JohnnyLucky]

You definitely do not need a 1,000 watt power supply, even with two GTX 670's. That rules out Cooler Master. The Corsair 850 watt power supply is a very good psu made by Seasonic. The best psu is the SeaSonic X750.

I maintain a power supply recommendation list based on technical reviews published by sites that have the proper equipment and personnel to conduct rigorous testing and in depth analysis of components. The Corsair and the Seasonic both made the list:

Scroll down to the Corsair and Seasonic sections where you can follow links links to the technical reviews.

 

[elijahsearle]

Ah no, a wee bit out of my reach, I was thinking the rasa rx360 kit.

http://www.frozencpu.com/products/14183/ex-wat-182/XSPC_Rasa_750_RX360_Universal_CPU_Triple_Radiator_Water_Cooling_Kit_w_RX360_Radiator_and_Free_Kill_Coil.html

And I was not planning on using a raid configuration. Just one ssd to begin with, for OS, then another for all of my programs/music/games/videos. I just don't have the money to spring for any SSD above 150, without cutting costs somewhere else.

 

[elijahsearle]

Thank you so much everyone! All of your comments have got my mind at ease. The x750 it is! I appreciate your time and hope your future endeavors are great!

Im using a NZXT Hale90 750W for my two 670s overclocked + 2500K overclocked + tons of case fans and hdds/sdds. No problems here.

Was easily running them with my Rosewill HIVE 750W which is very affordable.

The NZXT Hale90 750 is another psu that made the the power supply recommendation list:

http://www.johnnylucky.org/power-supplies/psu-recommendations.html

The Rosewill Hive 650 made the list too. The only reason the Hive 750 is not on the list is it hasn't been reviewed by a web site capable of coducting a competent review. That does not mean it is a bad psu. Just means it hasn't been reviewed yet.

 

[mouse24]

Edit: that was a terrible way to explain it, so much so I don't even want to try and salvage it.

(guys your supposed to reprimand me when I say something that off base)

^_^

The main reason I would always suggest the Rosewill HIVE 750W over the 650W is because the 750W comes with extra PCI cables for multiple gpus where as the 550W/650W do not.

Upgraded to the Hale90 for the sexy white design + gold rating + solid all black cables mmm.

Seasonic X series is master race.

Seasonic X series is master race.

That was my other option (X Gold 750W) but was drooling over the Hale90 when I saw it ;3

 

[Temile]

I love the Seasonics, but to be clear, either of these is going to be better than 99% of what people have in their systems today, so go with the one you like the looks of.

 

[Deleted member 217926]

The Hale is not a bad unit but it's not even in the same league as the Seasonic X.

[Temile]

Hey, I've got three Seasonic Xs, so I'm not going to argue with you. But if you have an open case, aesthetics can be important too. I assumed that's what he meant about drooling over it, because if you want specs, it is definitely the Seasonics that are drool worthy.

 

[amuffin]

Depends on color, white case go with the Hale, black case go with the Seasonic
