Can i pair a asus GeForce gtx 970 with a bit older power supply: "LC-Power LC600H-12 600Watt"

[MxPhenom 216]

I don't really think you should be in this discussion since the post makes it obvious you have no idea what you are talking about.

1. Where are you pulling 2x25 Amps from? Even if you go by the official nVidia Entire System requirement on the GTX970 product page, they only say 500w. That'd only be 42 Amps for the entire system*.
2. They only say 500w for the entire system to account for people using less than great power supplies. Because any decent 500w power supply can handle the minimal power draw of the 970.
3. I never said anything about the TDP. The ASUS GTX970 Strix, the card the OP is looking at, has a peak power consumption of 180w. And its average power consumption under load is 160w. These are actual power consumption numbers.
4. Why would you ever think a card with a 145w TDP would require 50A of power? You think a card that's consuming 600w** of power is only going to put out 145w of heat? There is literally no way that would ever happen. It isn't physically possible.
5. I've already pointed out to you that this unit is not made by Huntkey. Long before you posted, the OEM of the unit had already been established in the thread.
6. The PSU is more than fine for the task. You don't know what you are talking about, no offense, end of story.

*This is assuming the entire system is running off 12v. Obviously it isn't, the minor rails are used some. So in actuality, it would be less than 42 A from the 12v.
**600w is what 50A of power draw from the card would amount to. Yeah, I don't think there is a consumer card ever that consumed that much power by itself. Though it seems Stelly thinks 50A is a perfectly reasonable power consumption number for a GPU...




You mean exhausting temperature nicely. Odd, I have CX units powering much higher powered rigs with no issue with the PSU at the top! Must be miracles. Oh, or maybe it is just that you don't need $100+ Titanium rated units to power computers...

it also seems like he thinks TDP == Power Consumption. Which it does not.

As has been mentioned, the LC Power PSU is a very low quality unit not capable of supplying sufficient amperage across the rails for the 970, do yourself a favour and replace it before it forces you to have to replace a lot of other components.

newtekie, do you always recommend people buying cheap crappy low-quality PSUs?

About 9 years ago I had a Codegen 350W and it broke my 6600GT. After that I've stayed away from crap like that. I was 15 then and I didn't know much about PSUs back then.

 

[GeneralSnuggly]

I think i'll buy the gfx card (now i know i can atleast pair it with the power supply) and after that i will see if everything will be working properly. I intend to buy a better power supply in a few months anyway. Do you reccomend any for sli (970 ofcourse) in the future? (btw i know i need to get a new motherboard for sli)? thanks

Just because a unit has lower quality caps on the secondary rails doesn't make the unit crap. Those rails are very lightly used in modern computers, so power savings can be made there by using lower quality caps. That is my entire point when saying a unit doesn't have to have Corsair or Seasonic stamped on it to be good. You could use any brand in that statement. My point is that people seem to think the PSU has to be all top tier, built as best as possible, and in turn as expensive as possible, to be good. No, that makes a unit great. But there are plenty of good units out there that are still inexpensive. The trick to making a good unit is knowing where to use the inexpensive components, and Corsair is great at that. Even on their CX units, they use quality components and build the 12v rail very well. And the 12v rail is the important rail, because almost everything in a modern computer runs off the 12v rail. The CX units for example use Japanese Nippon Chemi-con primary caps. That is why the CX series falls into the Tier 3 of power supplies. Not great units, but still solid units.

I am not gonna argue these , since you claimed that the cards needs 180 W . The recommended amps for 970 is 50 A . Now , Corsair don't make their PSU , neither LC-Power . Corsair CX series are made by Seasonic and Channel Well . Channel Well also makes the Corsair power supplies of the HX series 750 W and up . Nobody said that a psu must be tier 1 , PC&P , Zippy or so , but that LC-Power is not even a decent psu . It is a tier 5 , you can say that this is all marketing brainwashing , but the price of the psu cannot sustain that . The producer must have it's profit , the reseller adds some , so how much is the cost of that psu in fact ? 10 E ? Well , i wouldn't entrust my computer to a 10 E psu . I don't think the card will need 50A , i know , and here's another guy that says the same :

http://www.tomshardware.co.uk/answers/id-2329240/potential-psu-problem-msi-gtx-970.html

Also these , from Nvidia's website :

Thermal and Power Specs:
98 C Maximum GPU Tempurature (in C)
145 W Graphics Card Power (W) - ( i assume Nvidia talks about thermal exhaustion here too )
500 W Minimum System Power Requirement (W)
2x 6-pins Supplementary Power Connectors

Now , saying that a GTX 970 needs 180W and telling someone that he doesn't know what is talking about , that's funny . No offense taken , no worries .

As for "The trick to making a good unit is knowing where to use the inexpensive components, and Corsair is great at that." - Corsair don't make their power supplies nor their water cooling systems . Their power supplies are made by Seasonic , CWT ( Channel Well ) , Flextronics and possibly others . Their water cooling kits are made by CoolIT Systems , Calgary , Canada .

But you were right in one aspect , i give you that : his model is not made by Huntkey . It's made by Great Wall , a chinese manufacturer that's not even in the tiered psu list .

Please make sure that the card doesn't require 28A per rail , tho .

 

[RCoon]

Corsair CX series are made by Seasonic

No, just CWT.

I am not gonna argue these , since you claimed that the cards needs 180 W . The recommended amps for 970 is 50 A .

12v * 50A = 600W
The graph below shows the AIB 970 uses 213W. In 12v Rail ampage, that means you need around 18A to push a 970. Plus the other few amps for other gear pulling from the 12v rail, so maybe 20-22A for a standard system.
*Cough*

i give you that : his model is not made by Huntkey . It's made by Great Wall

I did say that in my first post

As a closing comment, you can get an XFX ProSeries 450W PSU that will run your system for just over 40 euros (Sea Sonic made)

Some LC-Power models are made by Huntkey also , but this is irrelevant .

According to http://whirlpool.net.au/wiki/psu_manufacturers

CX-400 – Seasonic
CX-430 – Channel Well(CWT)
CX-430 v2 – Channel Well(CWT)
CX-500 – Channel Well(CWT)
CX-500 v2 – Channel Well(CWT)
CX-600 – Channel Well(CWT)
CX-600 v2 – Channel Well(CWT)

I can't find the other link that was more precise about CX series . Whatever .

I hope you're right and the OP won't need to upgrade his PSU to a true 650 W psu .

As for the graph , i don't know who to trust , the manufacturer ( Nvidia ) or that graph . Maybe Nvidia is wrong and the graph is right . I still have my doubts that that LC-Power will cause no problems to his system , after all .

There's also a difference between single rail and multiple rails psus .

CX-400 – Seasonic

Discontinued after manufacture in 2009

s for the graph , i don't know who to trust , the manufacturer ( Nvidia ) or that graph .

NVidia and other hardware manufacturers recommend PSU's based on total system power consumption, not GPU power consumption. That's why NVidia recommend a 500W PSU for the 970.

I'd still recommend a PSU upgrade over the LC unit, quality units aren't that expensive these days. Modern systems don't need 700W PSU's, 500W is ideal for standard modern systems.

I know this , i used to run a i5-3570K , a GTX295 , 8 GB ram , Asus Sabertooth , 1 SSD and 4 x 1 TB hdds , on a Silverstone Strider 500 . No problems at all . The same psu i've used to power up a 3870X2 , HD5870 , HD6870 . BUT my 6870 didn't wanted to work with another Silverstone Strider ( 750 W , 2006 model ) , although it had no problems powering up the GTX295 .

Not sure what they loaded their GPU with, but that's a great under-estimation for power usage. W1zzard's reviews use pretty good and accurate instruments, so I'd trust his power consumption figures over a manufacturers website.

Better to over estimate these things!

Yes , i was kinda surprised when i did a comparison between R9-280 and GTX 970 and saw better performance on 970 , with 100 W less power consumption .

 

[newtekie1]

newtekie, do you always recommend people buying cheap crappy low-quality PSUs?

I never do. I also don't recommend people over spend on PSUs when they don't need to either. I know very well what PSUs are capable of.

Some LC-Power models are made by Huntkey also , but this is irrelevant .

I never said some weren't made by Huntkey. My point was that the unit we are talking about here was not.

As for the graph , i don't know who to trust , the manufacturer ( Nvidia ) or that graph . Maybe Nvidia is wrong and the graph is right . I still have my doubts that that LC-Power will cause no problems to his system , after all .

NVidia is giving the number for the stock card, and their number is average consumption at load. The card the OP is looking at peaks at 180w(179w actually). Average load is 160w. That is because the ASUS card is overclocked from the stock, and also uses a different power design from nVidia's stock. W1z did a review of the card and actually measured the power consumption of the card. Just go read the review.

The thing is, the OP already has a graphics card. I can't ID it, but it is a mid-range nVidia card of some sort. If it is a 460 or a 560, it is already drawing more power than the 970 will. If it is a 660, we are only talking about about a 50w increase in power, or ~4.5A if you need it in amps...

There's also a difference between single rail and multiple rails psus .

Not as much as you'd think. Like for example, multiple rail PSUs aren't actually multiple rails. They all use a single 12v rail.

I'd still recommend a PSU upgrade over the LC unit, quality units aren't that expensive these days. Modern systems don't need 700W PSU's, 500W is ideal for standard modern systems.

I would recommend one eventually, especially if he wants to go SLI, but it isn't necessary right now just to run a single 970. Personally, if I was in the OP's position, I'd get the 970 now, and leave everything stock. Then, when I had the funds, grab a better PSU and a decent cooler for the CPU and overclock the CPU and GPU some.

I don't think it's a GTX 460 or GTX 560. iirc both of those cards required two 6 pin power connectors. It could be a GTX 660 those only required one 6 pin

I found one of the OP's other threads, it is a 660. So the power difference we've all ben talking about amounts to 50 whole watts. I'm sure that will cause his PSU to burst into a ball of flames!

 

[GeneralSnuggly]

So i finnaly got my gtx 970 (ASUS strix edition). And im happy to tell you, that it works perfectly! I could even overclock it a bit, without any stability issues or crashing.
