GTX 670 psu

[xcal237]

i might be on the wrong forum anyways do you guys think my psu can sufficiently run a GTX 670

i have a antec true power trio 430
http://www.antec.com/productPSU.php?id=60

it has 430 watts and 32 amps on the 12v rails combined

im running a 2500k @ 4.5ghz and 8gb of ram along with 1 hdd and 5 case fans

NVIDIA's official requirement for the GTX 670 is a 500W PSU. The True Power 430 PSU is a good PSU and you could probably get away with it (it's not like the GTX 670 pulls that much power), but it's up to you whether you want to chance that.

 

[cmdrdredd]

It only has one PCIe connector (you'd have to use adapters which is ok) but the real concern is the +12v rails. It seems there are 3 of them rated at 16A each which is pretty weak. I'd think about getting a new PSU to go along with the new Video card. A good 500w PSU is not that expensive and will ensure good power delivery for your hardware.

Depending on the voltage you're running for that CPU overclock, you could end up close to 350w with a GTX670. I'd say that's cutting it close. And I agree that the split rails could be an issue, especially when running PCIe adapters.

By the way, what GPU are you running right now?

 

[xcal237]

im running on a 5770. I was debating whether to get the 660ti or the 670 but i decided to get the 670 since its so close in performance with a 680 and when overclocked even surpasses it. I just researched on 670s and saw that there are allot of EVGA DOA 670s floating around which kind of scares me. But i will be buying a new PSU along with the 670 since its about time i retire this old psu and save it for backup just in case

one more thing i forgot to add does anyone have the GTX 670 FTW LE card http://www.amazon.com/EVGA-Dual-Link...ds=GTX+670+FTW

if you do can you confirm if this card can OC to FTW speeds or did EVGA just decide to sell this because they had 670s that didnt quite make it to FTW standards

I doubt you will be able to OC, it's questionable that you'll be able to run it at default settings to begin with, clocking it higher will make it a lot more prone to crash under load. Even if it does work for you, you'll be really pushing it and shortening the PSU lifetime exponentially. It's not a bad time to buy a good PSU, you can find bargains on good quality units.

im buying a new psu with the 670. im just asking if anyone here has the 670 FTW LE and has overclocked it to FTW speeds or more because im little bit skeptical on saving 10-20 bucks on the LE version when the standard FTW version can OC higher

 

[xcal237]

well i went for the 670 FTW LE since the regular FTW edition was sold out. Also got a 10 dollar coupon which sweetened the deal

for the psu i got the PCP silencer MKII 950w for a whopping $110 and according to reviews its pretty good besides the sub par voltage regulation. For the price theres no psu that can match this one

There really isn't too much of a difference between models when it comes to overclocking. That has much more to do with luck. So you're probably just as likely to get lucky with the FTW LE as you are with the FTW.

That PSU should be fine. You probably could have gone with something much lower wattage, cheaper, and slightly higher quality, but it will certainly work.

I was gonna get the modular version of the TX-750 but when i saw the MKII i couldnt pass up the deal considering theyr both priced the same and it has 80 plus silver and 200 more watts

 

[cmdrdredd]

My understanding is the ftw le is the replacement for the 2GB gtx 670 sc card that had a lot of failures. Larger pcb and more robust cooling like the normal ftw but a lower stock clock speed.

 

[xcal237]

should be good then. just didnt want to recieve a doa card and from the reviews ive been reading on amazon and newegg the stock 670 seems to have allot of QC issues. hopefully mine overclocks to 1300mhz :biggrin:

 

[cmdrdredd]

1300Mhz? Doubt it will go that high, but maybe you'll get lucky. My cards are full FTW models and they won't get that far. Highest my first card will go is 1243 before it has issues and my second card would do 1270. Memory about 6800Mhz max for both before I notice some artifacts and the like.

You never know though, every card is different.

 

[xcal237]

did you update the bios already?

 

[Termie]

did you update the bios already?

If you're talking about the EVGA bios, that will actually reduce your overclock. It's a stability update intended only to make sure the product doesn't exceed the stable boost at stock settings.

If you're talking about the 1.21v bios that's floating around, because that's not sanctioned by the manufacturer, many owners probably won't want to use it.

I'd say you have about a 5% chance of hitting 1300 with an EVGA card. Maybe slightly higher with the Asus or Gigabyte, but most of it comes down to the GPU itself, which isn't sorted by manufacturer. The card design can only help attain a high overclock if the GPU itself is a "golden chip".

okay guys i got my 670 FTW today and unfortunately my psu hasnt arrived yet so i decided to plug it in and it worked... installed the drivers and firmware update then proceeded to play bf3 on ultra settings... all i can say is wow

Good to hear. You're probably pulling about 300w with your setup, depending on your CPU voltage. I'd say you'll be ok, and unless you choose to use the modded bios to OC the GPU, you won't be pushing the wattage up much more than that even if you OC the 670.

 

[xcal237]

im a stupid idiot... so i was setting the fan curve in evga precision x which i am not familiar with since im used to ATi CCC i accidentally forgot to press apply so when i was playing BF3 the fan was only running on 30%... so after about 15 minutes or so i tabbed out to see what my temps were and i saw 101c on CPUID... so i exited that and checked precision x which reported the same thing ...

so now atleast i know that my card can survive such temps although im a bit skeptical whether i damaged it in any way... hopefully i didnt screw up anything it would suck if i limited my OC potential because of my dumb ass mistake... still waiting for my new PSU to come later this afternoon

Ouch. I don't even want to think about what would have happened if you kept gaming like that.

I think these GPUs can take more than 101C before sustaining damage, but yeah, that's pretty high.

 

[xcal237]

so far so good no artifacts or any weird textures so i think im good... my psu just arrived will be putting it in and see what my card can OC up to

 

[cmdrdredd]

It's fine, it was probably throttled way way down anyway.

 

[xcal237]

okay so i just installed my new psu and tried overclocking.... so max stable i could get this thing is +50mhz (1150mhz) on the gpu and +500mhz (7000mhz) on the memory.... sadly i wont be breaking the 1200mhz barrier for the gpu :'( but oh well its faster than a 680 right now and really thats all i can ask for

Depending on the voltage you're running for that CPU overclock, you could end up close to 350w with a GTX670. I'd say that's cutting it close. And I agree that the split rails could be an issue, especially when running PCIe adapters.

It's fine. Modern PSUs are rated to run 24/7 continuously at their rated wattages, more or less:

"Accurate power rating allows TruePower Trio to deliver its full rated power, 24 hours a day rated at 50°C."

This power supply will do 500W, not 350W
