Power Sup. help

[Dyeho]

Hello folks.
Can you help me out?

I brought some itens for my new pc but I don't know the power supplie I need to buy for those.

I brought.

eVGA 780i mobo
eVGA 8800 gts 512mb video card
2x WD 150gb 10000 rpm (raid 0)
C2Q 2.4 Q6600
4 gb ddr2 800

I would like someday to use sli w/ another 8800 gts.
But I really don't know what power supplie I need to buy for it work out.

Can you help me out? Thanks in foward.

Id strongly suggest against Sli unless you have a 24inch + monitor and have money to burn. The next gen graphics cards coming out soon will blow away anything you put in sli probably and therfoer its wasted money. Sli also only gives you around 20-80% performance bonus and usualy it averages 40% and most games will run 50+ fps on a single GTS without you needig the second.

Anyway, with that out of the way really you dont need more then 500w.

A corsair 520w will run sli 8800GTX. However make sure you have enough PCIE connectors. I beleive you only need a single PCI-E 6pin for each GTS? i cant remeber but i think the 520w will come with two of them. If not you may need to buy an extra.

It depends on the power supply brand. Corsair and Antec make rock solid PSU's, so you can get away with a 520W or 550W from either of them. But, if you're going to go with something like Rosewill (shudder) or the like, you're going to want to go over 600W. I've got a 650W PSU from CoolerMaster, and it's been extremely stable so far through my overclocking, but it's not one of the known brands, so I wouldn't have bought it if I wasn't on a budget.

antec psu's arnt that relable. I know people who have had several of them go.

thermalright,Antec,tagen, especialy hiper and any other cheap ones are ones i wouldn't buy. There are reasons a 600w Seasonic costs £100 and a 600w antec costs £50.

The ones to buy are seasonic, corsair, enemax and if you are looking for cheaper then ocz but they are louder and not as higher quality. Pc power and coolig are also well made but for the price you can get better usualy.

Seriously? Antec used to be really good PSU makers a few years ago, they were pretty much THE power supply brand. Wonder what happened... Personally, I've never heard of anyone complaining except for when they have too much crap hooked up, but that's not the PSU's fault.

[Nerror]

I'd go for the Corsair HX620W PSU (http://jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=21) (another review here (http://www.hardwaresecrets.com/article/371/1)). Plenty of power for SLI, very stable and very quiet and has modular cabling. It's listed as having 3 12V rails, but it's really a single 50A rail that is virtually split up into 3. This means it can handle any cards you throw at it.

[Ragenrok]

I would go with Nerror's choice as well, but thats just cause I like to leave lots of head room. 8igdaves choice will be just fine but if there isnt much of a price diff or you can afford the difference the 620 is a good pic.

They are just packing cheaper parts now. Hiper used to be top quality gaming psu's. Then they switched out alot of the parts and upped the volrtage to 520w. The result was they all got recomended by gamers who didn't know they had switched parts and alot of peoples pc's went bang. Their psu's used to be very dangourous and used to go bang way before they got anywhere near their wattage. Adding on 200w and putting in cheap parts is suside. The result is many people who know about the scandle hiper tryed to pull will never recomend them and will tell people to stay clear of them. If you check the spec of hipers they are also con items.

Their V12 will have 320w and they will put another 230w on the V5 and V3 which is not needed at all! my seasonic has 180w on its 5v and 3v and seasonic are like the best psu's money can buy. Its all cheap play to get you to think you are getting more watts then you are. Then when you run sli on it which can do it on under 500w it will go bang because your actually only getting 320w on the v12 which isn't high enough.

If you are buyig the 620w you might as well just go for a seasonic. They have 4 18a rails instead of 3 and are built to an even higher standard for not much more. But tbh, no one needs more then a 520w corsair unless running tri sli. My pc with a overclocked 8800GTX and a 3.6ghz Q6600 is not using more then 320w. Each 8800GTX is about 180w at load added on.

Wow, that really sucks. Glad I bought mine before all of that went down I suppose, my lowly 300W(ish) Antec is still solid after these 5-6 years I've had it.

[8igdave]

well thats hiper story but i beleive antec dont pack what they used to either. They arnt bad psu's but they do go. All psu's have failures but some have more then others.

tagen/hiper/thermalright/colour somthing and other non branded ones all have the highest failure rates. Antec arnt real bad but i wouldn't suggest them personaly as for the money you can get far better. seasonic,corsair and enemax are some of the best.

Sure, Seasonic is a good brand. They make the Corsair HX620 for example. If you're referring to the M12 series, they have an extra 60mm fan that causes extra noise though. They've recently launched the M12-II series (430W and 500W) that remove the extra fan to correct that. Certainly a good option if not going SLI. Well, they could probably manage a SLI setup, but there's more to it than max wattage.

When looking to get a PSU, there are several important factors, like power correction, ripple / filters, efficiency, noise, heat and the temps the PSU is rated at. Going for a higher max wattage than what is strictly needed is often a good idea if power consumption (efficiency) and noise (heat) is of any concern. An unstressed PSU usually means cooler and quieter runnings, and efficiency often peaks at around half the max wattage.

The Corsair HX620W has a 88% efficiency at 250W draw (pretty common for a non-SLI overclocked system during full load). In one review they pushed it to 746W in 48º C room temps and got stable power. That speaks of quality components and a PSU that can handle just about anything, and is partly why I am getting one. The other part is the low noise. 8)

Yeah i got the M12 but to be honest i cant here it at all. The fans are really quite, far more quiet then my graphics card or heatsink tehrefore the extra cooling is worth while imo.

hardcpo reviews are the way to go when it comes to psu tests. They push them so far many of them die. Any which survive their tests are quality psu's. They did tests and showed pritty much no difference between the 550VH and the 520HX except the modular cables.

This has been said before, SLI is not really needed, besides, 680i chipsets have left a sour taste in my mouth over the past months (Gotta love that Asus Striker/P5N32E SLI).

Do yourself a favour if your planning on overclocking and get a P35 or X38 based mobo.

Now thats out of my system, for power supplies; pretty much any version from Seasonic and/or PC Power & Cooling above 600watts will do:P

Corsairs are a good choice since they are of Seasonic/or/CWT built as well:P

Edit: I prefer a bit overkill on the PSU, you can always use it on later builts:)

[8igdave]

why above 600w? ive already pointed out that sli 8800GTXs win run on a 520w corsair. Anything over is paying excess which may be spent else where. I cant complain, i have a 600w Seasonic M12 lol, but i wouldn't advice people to spend that much when a corsair will dothe job unless they had the money to blow on it or are buying something close to the price of the seasonics anyway.

[Dyeho]

Real Thanks for the replys folks...
Well I live in Brazil and here we don't have all those choices...

So i will have to choose between:

Thermaltake - W0129RU - Purepower 600W
Cooler Master - RS-520-ASAA-A1
Cooler Master - RS-700-ASAA-A1
SevenTeam - ST-750EAJ

So witch one I should get for my pc?
That I have pleny power to do SLI, overclock and handle my HD.

Thanks in foward.

neither?

Thermaltake are not very reliable, i beleive their true power series is alright but personaly wouldn't buy one. Cooler master not heard much about, seventeam not heard much about. How much are each of theese costing?

Why dont you get the corsair ones we all suggested? they are the best in the price range by far.

Definitely the SevenTeam. They make great PSUs, and OEM the Ultra-X PSUs for example. I am not sure about the noise levels, but the quality is top notch.

[8igdave]

O really? Yeah then go for that, i have no experiance with them. Check out some reviews on all of them and see which is the best. But i dont suggest the thermalright one.

There seems to be quite a few brands sold over in america which are not as commen here, or at least i dont see them on the shops i look at.

[Dyeho]

Thanks again folks.

1,00 USD = R$ 1,70 (brazilian Real)

Seventeam ones are really cheap (for brazilian parameter) like R$390,00 (229 USD) - 750W
Those from cooler master 520W - R$ 480,00 (282 USD) and 700W - R$600,00 (352 USD)
And the thermaltake one costs 294 USD.

Don't get scared. Here in Brazil things are really expensive. If you want to get a good pc you will have to spend lot of money /rude to Lula!
People here don't like seventeam, seems that they only send crap to here.

I like corsair. But I just can't find no where to buy.
So i will have to buy one of those.
Or some aurora extreme 700w.

So Cooler master is more trustable than this thermaltek?

[8igdave]

did a quick search and cant find any reviews. Have a look around.

[Dyeho]

Aye... kinda hard to find one for those =/

[zer]

The thermaltake you pointed out is only ATX 2.0 speced...

Im currently using the 144RU model, which is modular. Serves me well although I am changing to something else.

Can you get any kind of PC Power & Cooling were you live?

Aham...

The dificult is to find a specific iten. But general itens are easily find.
You just don't find corsairs PSU, OCZ memory (There is a Kingston reign here lol), and other stuff.

[zer]

Kingston memory isnt bad... Granted Im a little BIAS towards Crucial and Patriot, Corsair is also good as long as you get the VERY HIGH end stuff. Their mid range is easely eclisped in performance by Gskill or Crucial in most cases if not, all cases.
