Which One would you Choose?

[vegettoxp]

Hey Guys, I just did a quick price check on the two brands of power supplys and I was suprised to see that I can get more watts for my money with OCZ. I just wanted to get your guys opinion on which one would you choose if you were in my spot.

OCZ Model that I am looking at is:

OCZ GameXStream 850W- OCZ850GXSSLI or 1010W - OCZ1010GXSSLI

The Enermax Power Supply that I am looking at are:

Enermax Galaxy EGA850EWL or Enermax Infiniti 720W

In my opinion when I did the quick price check, OCZ really got my attention. I am not a Hard-Core Gamer. The Power Supply that I end up picking would have to put up with:

Intel X38 Chipset, Intel Quad-Core Processor (45-nm)
Asus or Intel Motherboard
2 Roms
4 HDs, One of them Raptor X
I have a CM Stacker 830 With all seven 120mm Blue LED Fans
And Plus other stuff that I have or will have in the system.

This was just a quick list of things the power supply should be able to handal. So guys tell me if you were in my spot and you had to pick between OCZ or Enermax Power Supply, Which one would you choose?

THX for all your help!

P.S. Fusion

Did I miss what kind of video cards you'll be using? That's sort of the most important aspect of considering a video card, because unless you're getting a pair of 8800's all of your choices are total overkill.

The reason you get more wattage for your money with the OCZ is... well... let's just say you get what you pay for. Believe it or not, the Infiniti 720W is the far superior unit of your four possible selections.

No one else is gonna reply now, coz the guru has spoken. I'm guessing if you say you're not going to put any cards in SLI or crossfire, he will tell you that something 600W will be fine as well. And even if you do sli/crossfire, a 620w corsair should still be plenty.

The graphic Card that I am looking at is the EVGA 8800GTS 640MB. And I don't plan to do SLI At All. Just One graphic card.

Well Guru is right....

Can I trademark it ?

@ vegetto, corsair 520hx or 620hx. That's what you should be looking at. I dunno how much energy that case needs with all those fans, but since the GURU said all options are overkill if not going dual 8800's then I dare saying 520/620 corsair will be plenty of juice for you.

Should? 2 Ultra's and an assortment of gamer-class FRU's would tap-out a 620 easily.

 

[Puffnstuff]

I only run enermax ps's because I've never had one fail on me and they've got rock solid rails.

Ultra X3, 1000W. Read some reviews. :thumbsup:

 

[mxnerd]

1000W? Do we really need a big oven?

Wow! Efficient, well-built, modular AND pretty too?

 

[jonnyGURU]

And also available in 600W and 800W (same build quality.)

Even though it's an 8800GTS, if you're only doing one in that rig, a really well made 600-800W is more than enough.

 

[mxnerd]

To all experts here:

If the PSU is rated 500W (on the label) and it passed 80 Plus certification, does it mean the output will be 500W x 80% = 400W under 100% load and 100W wasted as heat?

Or that 500W means output will be 500W under these 100% load and the consumption on the wall will be 500W / 80% = 625W and 125W wasted as heat?

And what is the best load % that is good for PSU running 24/7 that can last at least 3 years? Thanks.

 

[GalvanizedYankee]

It means a 500W unit would supply 500W of DC power to the comp and the PSU's fan would have to deal with the waste heat of 100W.

Many enthusiasts over spec the PSU. I would say between 40% to 70% loading. Most of us will do well with a good 400W unit that gets loaded from 150W to 250W.

I suppose then that would be 125W as heat and consume 625W on th wall?

Jonny, could you put together a qaudcore system, 2 8800's gtx/ultra's, 4gb of memory, all inside a coolermaster stacker 830, with hmz let's say 5 HD's, of which 1 a raptor, 2 optical drives, a soundcard, a NIC, and anything I might have missed but is fairly common in high-end pc's? Then tell us how much it uses? I'm really dying to know, more or less.

 

[jonnyGURU]

I had built a similar machine for someone that didn't like to boot with anything less than a 600W. That said, you could assume that the potential to draw more is there, so it would need a 750W or better to "be safe."

 

[MarcVenice]

hmz, thanks for the reply.

Wouldn't you think that supplying PC buyers with some decent guide as to what they need in terms of PSU could be something really usefull? You're a tech guy, I bet you've got all kinds of parts laying around, and you build systems for other people. Wouldn't it be rather easy to test a wide set of PC's and determine their max energy usage, and the PSU that would be optimal for that kind of usage, so it runs at nearly it's highest efficiency? Starting with let's say a e4300, 1 hd, 1 optical drive, low-end graphics card like 8500gt or 2400pro.

I know there are calculators, but if you have an extensive list of different PC configurations, it would be real easy for people to look up. With the testing you do, you could do it on the side, and shouldn't take to much extra time?

AND they come on the market shortly after I buy another unit! :thumbsup:

Jonny, what are you thoughts on modular cabling? I read that the connection points create resistance, which in turns lowers efficiency. I've also read that they don't cause much of a problem, if any.

I am not jon.

The short answer...NBFD.

The long answer http://www.motherboards.org/articles/guides/1488_1.html This link is to be found at jonnyguru.com > Links, then about half way down the page.

NOTE: The guru comes from a mispronunciation of his last name...it stuck. It just started as a joke amoungst friends. T'is true according to jon.

 

[HardWarrior]

Thank you, Yankee! A very informative read. The moral of this story? Modular, not modular, there's no hard difference. Go for quality.

The fact that PCP&C is a notable distributor of "modular=disaster" FUD makes this situation all the more sad. It was interesting that the reviewer seemed to think that his hard work wouldn't change many minds on the subject.

 

[GalvanizedYankee]

The author of the linked article is jonnyGURU...if that fact slipped by you.

Mr. Dodson of PCP&C did his marketing very well indeed...Don't cha think?

The worst modular out there is the Hyper that uses DIN like microphone jacks. They look like small chrome udders. Those use shared pins at the PSU. Sad really!
ATX pins and shells is the way to go. Most PSUs are semi-modular with atleast the 24 pin hard wired. I think only the Silverstone Striders are full modular and only the 600W or 750W are worth having. Silverstone does offer a short cable set for these units and this is good news for those having these units and wanting to go with a small case.

Anyway...if there are any other full modular PSUs out there that use ATX/Molex shells, this short cable set should work with them too.

I ramble.

 

[HardWarrior]

Yup, I missed that!

I think you're more than old enough to remember when nothing approaching internet was available, right Yankee? Isn't it great that an individual like jonny can make a contribution of this manitude, that's viewed by so many enthusiasts? I love the modern era! :light:

I looked that that unit before my last purchase and ASSUMED that the since the connectors were metal they'd be better. Live and learn. I'm also wondering why I didn't take a hard look at Silverstone. Speaking of shorter cable runs, it was surprising to read that an 18inch cable had appreciably more resistance than a modular connector.

Hey Guys, I have learned alot from this thread and I am gona say no to OCZ Power Supply. Now I have narrowed my collection to these Power supplies.

Infiniti 720 or Corsair HX 620! If you guys were to recommend me a Power Supply, Which of these two would you recommend? I have heard a lot of good things about both of these power supplies. Expecially the Corsair HX620.


These Two (Maybe) PCP&C Silencer 750 or Seasonic M12-700

Once again thx for all your guys input in this Power Supply Topic

P.S. Fusion

Yeah... I thought about it. I think it's the coding of some sort of calculator that is always the hang up. I worked with a guy a couple years ago to make one and I was happy with it, but then G80 cards came out and it was time for an update and I got lazy.
