Which one? Antec/Corsair/Seasonic

[Compman55]

Building a haswell rig, any recommendation? Must be modular.

Full ATX 1150 mobo
Xeon E3-1245V3 or K series i5
16GB ram now, 32 later
No video card now, but planning for only one later
DVD RW
1 SSD
1 Spinner HDD of some kind / capacity

Enermax then corsair.

Seasonic G550. It's all the power you need and rock solid.

It really depends on where you're buying from and exactly what video card you're planning to get. The answer to "what to buy" always depends on "what does it cost" which in turn depends on where you buy from and when.

Check the Enermax 430W Revolution'Xt.

 

[Compman55]

G550 = 550w

That looks like the best bang for buck. I will settle for that one.

Question: This will be a 24/7 application. Lets say my PSU is oversized now at 550w, will it comsume more power than a 350w at the same exact load? Or does this mean I have a higher power ceiling?

Reason being is because I will not be buying a state of the art GPU. I will buy a used top of the line card in 2 yrs or so.

Corsair HX series. Its modular and it supposed made by Seasonic (when I researched it was claim by many forum members). Virtually silent since the fan doesn't spin unless you're at 80% load and capacity.

The rated wattage (along with the unit's quality and the maximum current of its +12v rail) determine s the power ceiling. Actual power draw depends on the components connected to the unit, the utilization/load of those components and the unit's efficiency.

The G550 can handle a 200w-250w graphics card with moderate overclocking. If you want to be able to overvolt such a card properly using aftermarket cooling, or if you want to be able to install a card with dual GPUs on it (e.g. GTX690) then get a 650w unit

Corsair HX series is mostly made by Channel Well Tech

is Channel Well Tech crap? I thought I had something good by Seasonic and now it turns out I dont

No, the CWT HX units are also very good quality.

Corsair CWT built units are excellent, but many other CWT units are only average. They're still head and shoulders above lots of other OEM's like HEC

 

[Compman55]

How important is modular psu's? I ask because there is corsair CX series for $25 after rebate. It seems unbeatable, 450w, haswell support, just not modular. I wonder how the ripple would be, and electrical noise throughput.

 

[lehtv]

There is no CX with 450W. You probably mean 430W. That's not enough to support any high end graphics card. CX series in general have mediocre capacitors but perform pretty well for the cost.

Modularity is overrated.

With a Xeon, you can get about 300-350W for the GPU out of a 430W PSU.
That's high-end to me.

 

[norseamd]

anything wrong with getting a seasonic unit? thought that they were very realiable.

The CX430 has one PCIe connector and a +12V rail worth only 32A or 384W. If you want to stay within long term safe load, you won't use a 250 watt graphics card with it. CX series isn't high quality enough that you could simply slap on a high end card on a 430W unit when the official recommendation is 600W.

Ah, didn't expect that cheap power supplies are still that rubbish.

Anyway, I stand by the Enermax 430W - it's quite expensive, but really sets itself apart in the 400-450W group by being modular, 80+ gold and having a 140mm fan. The only downside is the price, and the single-rail 12V layout, though the latter isn't quite that bad, considering the 35A max. load.
It's also quite compact, and fully Haswell certified.

Ahhh, the CWT built Enermax Revolution XT series. Overpriced for what you get. I mean, really, using Capxon electrolytic caps in such a high priced power supply? And CTW's soldering isn't up to the standards a better performing unit like the Seasonic G-series power supply has.

I'd recommend saving a few bucks if anyone is thinking of an Enermax and look into the Seasonic G-series. NO second class capacitors, better build quality (much better soldering across the board), better electrical performance (the Rev. XT only manages to suppress +12V ripple/noise at 75mV while the Seasonic manages to keep the +12V ripple/noise down at 25mV).

True, the Seasonic has two fixed cables, the 24-pin and the 8-pin ATX connector, but given that both those connectors are necessary in any computer built today, I don't slam it for that. Oh, and the Seasonic's $20 cheaper.

let the man decide for itself.
(i for one prefer to run my PSU at 70% load or less, for maximum efficiency and lower electricity bills. i find that, over 5-6 years, it pays for itself)

 

[Compman55]

How about this antec? Seems like a better bang for the buck than the seasonic g series.

[MongGrel]

I've seen things on other forums were people have had problems the CWT's, I 'd get the Seasonic and call it a day myself.

If it was me I'd get this, but you're looking for modular I guess.

http://www.newegg.com/Product/Produc...82E16817371072

Put the 550W version of it in the over sized HTPC build in the bedroom recently and it was overkill.

I tend to spend the extra 10-20 bucks on PSU's when I build them myself.

It's a good unit, no denying it. G series is better in terms of efficiency and voltage regulation though, but I have to agree the G650 is not worth $105 (nor is the TP-650C worth $100) when a HCG-620 can be had for $60 AR. These are all Seasonic builds with 5 year warranty.

If you do want Gold efficiency, Rosewill Capstone 650W ($78 AR shipped) is the one to got right now. Also has 2 years longer warranty. Otherwise, go with the HCG-620

EDIT: Also found a Platinum unit on sale: Rosewill Tachyon 650W $90 AR AP. It's a high quality Super Flower build with 7 year warranty, much like the Capstone but more efficient and semi-modular too.

 

[MongGrel]

Yeah but I'm a bit of a Antec Fanboi myself, have a Delta built Antec CP-850 in an Antec 1200 been running the last 6 years I guess in the main rig, just stuck a X5650 in it at 4.3, with many other things that are still cooking along great.

*shrug*

Just the way I'm rolling.

:thumbsup:

But most things Seasonic are gonna be reliable.

 

[lehtv]

Are you an Antec Fan or a Delta fan? The HCG-620 is Seasonic, not Delta. It's a Seasonic S12II clone, basically, and it's probably further from the old Delta-built CP-850 than a modern Super Flower build.
