[Official] AMD R9 290X / 290 Owners Club - Page 4005

post #40041 of 43981
I have a watt meter that my tower is plugged into so I can see what I'm pulling at a glance. I'm using a XFX 850w Black Edition PSU.

Both of my 290x's at OCed to 1150/1500 with the 4790k at 4.7ghz

These things are also running, but not drawing a ton of power:

12 - 120mm rad. fans
4 - 140mm case fans
Swiftech MCP-355 pump
LED lighting
Cold Cathod lighting
2 - SSD's
1 - HDD

When I ran furmark awhile back the rig was pulling just over 1000 watts without issue.

This is in firestrike with both cards at 99%


BF4 with both cards at 99%

I looked up what a reference card was and I realize that is not what I want. And yes i do plan to water cool the GPU but not right away since I already have $2400 out of my pocket right now for this system.

I guess this is the card I have come to after reading your comments and looking at some benchmarks. What do you think ?

I have that exact card. I've gotten mine up to 1275 on the core at 200mv. Its beast. I wouldn't count on getting one like mine, I think its rare. Still, great cards. I'm temped to buy another one.

This PSU thing has taken a lot of replies already.

I don't wanna mention any names but it seems that the confusion is growing.

I don't understand why some would not consider spending a little extra to get a little headroom on PSU power knowing that everything in the system connects to a power supply. If that thing goes bad for overloading, chances are, it will take components with itself. Does this even make sense?

Also, people are putting too much emphasis on spending a premium on high quality units more than power ratings. Even basing calculations to what reviewers shown. Like, a certain reviewer tested a unit past it's rated output. i.e. 1000W on an 850W unit.

Some people take this and buy an 850W unit when their calculated load would be around a 1000W --even more.

Doesn't sound so healthy of a thinking for me. But then, it'll take a hard lesson to learn on something that is generally accepted truth or even myth sometimes.

Good luck.

I figure my system is going to run around 650-700 watts but to give myself some headroom and room for upgrading I went with a 1000 watt psu. Just makes sense to me.
post #40046 of 43981
PSU is the most important part of PC period. Like many have already said if your PSU blows due to overloading pretty much expect it to take some things with it. gunner.gif

Though, contrary to my previous statement, PSU prices per Watt are not linear. So maybe, some people are not up to spending $300-400 unto a PSU. They'd rather spend it on a GPU.

I don't want to trust a sub-$200 PSU to handle my 290s, my CPU, and Motherboard personally. thumb.gif

That's reassuring.

BTW bud, I think I read somewhere you mentioned your 290 is crap at mem OC.

Giga is it?

If you're planning to waterooling then that card is not for you. No full cover water block available for that card.

My cards are referenced cards. Before putting them underwater, I played BF4 games for hours without the cards throttling & I played with two cards in Crossfire. There's a couple of things you need to know or should know when using referenced cards with referenced coolers; 1) don't overclock, 2) use custom fan profiles & 3) don't mind with the noise. If anyone having throttling problem, they're not doing it right which basically means user error. My ambient pretty much above 32C most of the time.

Please go read that article I posted and then come back and we'll talk.


Just because a card has an 8 and 6 pin connector doesn't mean it will only ever draw the rated power through it. Look at the 295x2, dual 8 pins on a card with two 290X GPUs. You can do the math. I'm not saying your 290x will do the same, but it can and will (at times) pull more than what those connectors are rated for. It should not be taken as gospel that that is all the power it will ever draw - "because connectors". It doesn't work that way.


There are plenty of lower power cards that use 8 and 6 pin connectors which are totally safe to run on your 520w PSU, that doesn't mean you can run any GPU, regardless, just because it has the same connectors. Again, it's not that simple.


Another thing about all these "reviews" you keep holding up as pure spoken truth; How long do these reviewer actually use and test these cards for? A day? A few hours? That's really about it. Just long enough to gather some number, slap them on a graph and show you where they stack up relative to the other cards on the market. The power consumption numbers are what they are, and again, that equipment is not inclusive of the true power draw characteristics of these cards. You'll also notice they don't use 520w PSUs for testing, they typically use units in the 750w+ range because they don't want anything to interfere with the performance of the components in their test system.



280X - 250w TDP

290X - 290w TDP Warning: Spoiler! (Click to show)
On a lower capacity PSU like the one you're using, that 40w difference can be the difference between being close to or on the limit and not.


The 290X doesn't have junk power management. Again, please go read that article. I'm not discussing this further with you until you do so. I don't have time for people who refuse to listen to reason and tell me I'm spouting BS. If you want to use your 520w unit, so right ahead. A number of us here have warned you.

When it comes to PSU's, "cutting it close" is not "fine". The PSU is the most important part of a PC. I just don't understand the mentality behind using something that is barely enough and putting the rest of the system/components at risk. You're all certainly free to use whatever parts you wish, but I will hold to the fact that saying this is "ok" is not ok.

TDP is not the same as power consumption.  It is the amount the heat that needs to be displaced under normal operating conditions.

Just want to be certain you are aware of this.
That is correct but if the card is outputting let say 250W of heat, how much power do you think the card is pulling? The answer is more. You can actually use TDP value especially with graphic card as a reference for how high (wattage) PSU you should get.
