600W Enough to run 2 8800GTs in SLI?

[VtPC83]

Hi All,

Just like the title asks, is a 600W power supply good enough to run 2 8800GTs in SLI?

System Specs-

Intel Core 2 Duo Processor E6750 @ 3.0Ghz with Thermaltake MaxOrb
Asus P5N-E SLI nForce® 650i
2GB DDR2-800 PC6400
250 GB HARD DRIVE
18X Dual Format/Double Layer DVD±R/±RW
2 Spare Fans on Side of Case (72mm and 80mm)

Thanks

Jeff

If it is a quality 600w power supply you should be okay. I am using a 480 watt supply for the rig in my sig. I think a 8800GT only has a TDP of 120watts or so. You won't have a lot to spare but it should run fine.

It's possible but you really should tell us what brand your PSU is and what amperage it has on the 12V rail.

What 600W PSU?

Exact model please

My HX520 could easily handle a couple GTs in SLI (it's 520W), but as mentioned, amperage is the key, not wattage (if it has adequate amperage, wattage will be adequate consequently).

how would a 2 year old FSP Epsilon FX600-GLN hold up? 600 watts max 15a on the pci-e rail (dedicated to PCI-e)

Certified Power Supplies

It's possible, depends on the quality of the 600W PSU and the amps it can provide, as noted by n7.

PSU is one place you don't won't to go cheap with SLi. I got constant TDRs and bluescreens with my 3 way on a non certified 1200W, moved to a certified and that problem vanished.

I think the FSP unit can run 2 8800gt's. But if you should, on a 2 year old unit, that prolly costed 100$, different story. Do take aging caps into account, and I don't know if it's rated at 25c continous or 40-50c continous. If you want to be sure, ask on the PSU forum instead.

nRollo, WHAT psu's are we talking about, which ones are in fact tripple sli-certified? I'm getting the impression that we should only buy SLI certified psu's if we want to run SLI...

The ten 3 way certified PSUs are listed in the top drop down on the page I listed, their are about 50 listed for 8800GT SLi in that drop down list.

I don't want to give the impression certified PSUs are the only ones that can be used, but that list is a good place to start because those have been tested by NVIDIA.

I'd say JonnyGuru's website is another good reference, and that you want a quality power supply with any high end SLi. (or Crossfire for that matter)

I think a lot of people's TDR problems with Vista are their PSU failing to supply sufficient power to the cards, based on my own experiences with 3 way and a non certified PSU, conversations with NVIDIA, and what I've seen on nZone.

I always stress about power but if this helps at all i run all of this on a silverstone 650watt and dont have issues unless i get a little oc happy.

e8400 oc @3.8ghz
4gb ram
(2)WDRaptor74GB raid 0
(1)WD320GB
(1)WD250GB
(2)hd3870 w/ low oc
(1) internal dvdrw
(1) external dvdrw
FANS - (1) cpu, (4) case including a 180mm,(4) video cards
bluetooth, logitech 2.4ghz, usb speakers

Completely agree, don't skimp on a PSU when you are going to run a couple of high-end videocards costing way more then a decent PSU would cost. But yeah, sli-certified isn't the be all and end all of PSU's.

And I don't really think that the list provided by nvidia isn't such a good place to start with, I see dozens of psu's I would never recommend to anyone. And a lot of units are just that, sli certified, but 1000w units for 2 8800gt's ? Probably a little confusing as well.

LOL

You make a good point.

How accurate are those lists, rollo? I have a hard time believing my coolermaster real power pro 650 can't handle a pair of G92 cards. However, it's listed on the "other cards in SLI" category.

 

[KBTuning]

my 700watt OCZ does just fine with my Q6600 @ 3GHz and my two 9600GT's in SLI overclocked to 790/1830/1000 and with 4GB of ram....

its worth spending the 140 bucks or so on a power supply.... think of it as building a 900hp turbo honda... sure itll run on 93 octane but you'll have almost no power and if you put that C16 gas in it you'll be able to use that 900hp

My guess is that it just hasn't been tested for two G92s, and that your PSU would run them fine.

I'm actually going to a CoolerMaster 1000W ESA power supply/AquaGate Max watercooling/Cosmos case for the build I'm putting together today.

I really like their stuff, been using a Cosmos case for one rig for a few months, like it better than any other case I've used.

I've been looking at the Cosmos as well for my next upgrade. It appears to be really nicely put together. I love my RPP 650 PSU. It's absurdly quiet and and cool, and I've only seen very positive reviews for it.

 

[MarcVenice]

The real power pro's are qaulity units, and can often be had for very little money compared to equally build units with the same amount of wattage.

Btw, I like the cosmos s, the regular one is kinda meh. If you've got money to burn, at least get an s

I got my 650 for $80 on newegg last fall I haven't seen it below $120 since then.

 

[MarcVenice]

The 750 used to be 80$ AR at zipzoomfly.com, AR of course ...

Is that the tri sli 9800gtx or the 9800gx2 system?
Hopefully you have a e8500 @ 4+ ghz to run them cards.

An OCd E8400 actually, but at 25X16, the CPU doesn't really matter.....

 

[Tim]

I have a 600watt PSU (don't remember the brand at the moment, it wasn't too expensive I think around 90?) and the following running with no issues or problems running for 2 months straight now. (stock speeds atm)

(link in sig)
e8400
evga 680i
2 8800gts 512mb in SLI
2 WD 160gb HDD in raid0
4gb of ram
1 optical drive
6x120mm LED fans
Thermaltake watercooling
And two cold cathode lights.

You get the point...

he's got 2x9800gx2's, though I'm not sure if they'll both run together in quad-sli yet. care to fill us in rollo, or do you have to wait until tomorrow? remember, it's already tomorrow in new zealand!

FWIW I could not get my dual G92 GTS system to pull 500W from the wall. Came close.
