A NewEgg Tale: The 3 PSUs

Last response: in Components
Share

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=N82E168...

Corsair TX 850 850w Enthusiast Series 80plus Bronze $104.99 after $20 rebate
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

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

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)

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. ;) 

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.

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?
Power supply Expert

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).
Power supply Master

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:

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-recommend...

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.

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.
Power supply Expert

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.
Power supply Expert

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.

Firstly, I don't accept that Eggxpert tiered list as evidence, they've got units in the wrong place all over, it's incomplete, it's full of errors, inconsistencies, etc.

Secondly, going through the actual test results from those two HardOCP tests, I'd definitely say that they are in the same league.
Below is a summary of both their results:
Seasonic X-750
voltage regulation 120V tests
+12V rail / 13-60A: 0.21V change
+5V rail 2-7-2a: 0.04V change
+3.3V rail 1-5-1A: 0.05V change

efficiency 120V tests
87.5-90.07-89.74-87.65

ripple and noise
+12V rail : 35-10mV
+5V rail : 10-20mV
+3.3V rail : 10-20-15mV

NZXT Hale90 750
voltage regulation 120V tests
+12V rail 13-60A: 0.18V change
+5V rail 2-4-1A: 0.07V change
+3.3V rail 1-3-1A: 0.04V change

efficiency 120V tests
86.63-89.07-88.59-86.76

ripple and noise
+12V rail : 15-40mV
+5V rail : 10-25mV
+3.3V rail : 10-25mV

Thank you ^_^

@ Muffin, you don't need a white case to get the NZXT Hale90, obviously my build proves that. Check my post in the hardware gallery for an example.

When I said I was drooling over it compared to the seasonic, mainly was because 1. Equal quality, 2. All black cables/connectors, 3. White + black design. Versus the Gold black design of the seasonic and not fully black cables.

Aesthetics ftw ofc :) 


@anort3 after reading the reviews the only difference I can find is the seasonic is "quieter" (quoted from HardOCP) and my hale90 is already dead silent so I don't see how it can be any quieter lol.

Going off of specs, both power supplies are drool worthy. Funny how people down talking the hale90.



"really never becoming audible in our background" "
"Sure there have been quieter 750W power supplies, such as the Seasonic X-750"

That sure is tiers ahead, (never really making a peep, only seasonic x is quieter.) How is something quieter when the other thing never became audible in their study? Bias reviewing ofc.
Power supply Expert

Since its now about aesthetics, I'm just gonna point this out, the predone connectors the on the hale90 appear to be non sleeved (well you really can't call that sleeving).
Power supply Expert

I'd turn it around so you have the all white side showing. This means you'll be drawing air from inside the case instead of off the floor, but there's a lot of reason to believe that a good modern psu can handle the extra warmth no problem. Lots of discussion about this on http://www.overclock3d.net/ in Tiny Tim's reviews.

If you're going for looks, go all out.

I don't get what point you were trying to make with this

Both sides show the label so there is no all white side :p 

I prefer mine having its own air circulation versus drawing air away from my gpus but I can always give it a test and see if it actually makes a difference.
