Hello evreyone ,

i want to upgrade my computer's hardware :

here is my hardware i have :

MOBO.....: AsRock FATAL1TY FX 970 / AM3+ Socket
RAM........: 2X 4GB Corsair Vengeance 1600 MHz EDITED (9-9-9-24 1.50v ver 1.2)
CPU........: AMD FX 9590
Water-C : Corsair H105 HydroSeries
GPU........: SAPPHIRE Radeon R9 280 at 3GB Ram OC edition ( GPU Clock : 940 MHZ / vRam Clock 1250 MHz )
GPU.........: AMD R9 295x2
PSU........: Corsair CS 750 M . LEPA B1000M
SSD........: Samsung EVO 850, 250GB
OS...........: Windows 8.1 PRO x64 Bits
HDD'S....: 1x 1TB + 1x 1TB + 1x 4TB
DVD........: 1x DVD Writer Model TS-H653 picked from an another computer
Wi-Fi.......: TP-LINK TL-WN881ND ( a bit laggy some times :/ i have a D-LinK DWA 547 with 3 antennas much better but i cant plug into the mobo because its on PCI and not PCI-E frown.gif )
Case......: Corsair 450D Windowed

i plan to Sell my Radeon R9 280 to upgrade it to a Radeon R9 295X2 in CF-X

for the moment, i buy the R9 295x2 , and later this Year or mabe in 4 or 6 years, i will buy another R9-295x2
i planned to buy 2x4GB Corsair vengeance 1033 MHz Ram Sticks when i will buy the second R9-295X2

i want to know how much power i need for theses videos Cards ?

i was reading many many dirfferents things, but i dont want to spend monnies and monnies !

i know i must choose at least 1200W PSU

i read good things about theses two models

- CoolerMaster V1200..platinium 80+
- Corsair Ax 1200i.........platinium 80+


i saw a video on YouTube where its almots the same configuration i plan to buy
( same case , same GFX Cards, but it as an Intel Processor )

https://www.youtube.com/watch?v=v0NwTeq9Iy8

this Guy use a 1500W Silverstone PSU , are 1500W really needed ? i mean, by buying an 1200W it will not be OK ?

if we do some basics / theorics mat :

we need at least 28+28 A , as it's writen on AMD Website, the R9 295x2 needs 50A to run properly (but 28A+28A are 56A)

http://www.amd.com/Documents/Selecting-a-System-Power-Supply-for-the-AMD-Radeon-R9-295X2-Graphics-Card.pdf

and then 50A + 50A if want to do it in CF-X mode !

220W TDP (from the FX-9590) /12 to get the A = 18.3333333 Admitting its 18A

we have 100+18A in full charge Mode without HDD'S and SSD stuff

118A * 12V = 1416 Theorical Watts

From here,Did i really need a 1500W ? Or are the 1200W PSU'S ok for this use ?


My precedent Hardware was ;

CPU : AMD Pehnom II X4 955 Black Edition ruuning at 3.2 GHz + Cooler Master Hyper TX-3 EVO
RAM : 8GB
GPU : AMD Radeon HD6950 2GB
Many HDD at least 5 from various Sizes but 3.5"
PSU : 600W OCZ ModXstream PRO ( but the brand is over and no longer exists )
Case: No name

One last thing, sorry for my bad english if any smile.gif

if you can give me some advices it will be great ! smile.gifthumb.gif

First, the 50A requirement is for the entire computer. So, to power a computer that has one R9 295x2 in it, they are recommending that you use a PSU that has a 12V output capacity of at least 50A, which is 600W. This means that a good quality-made 650W PSU would be plenty if you had just one R9 295x2 in a computer because a good quality-made 650W PSU should have a 12V output capacity of 648W (54A).

 

Don't add amps like that by the way because you will always get unrealistically high results. ;) So, never add amps to amps in the way that you did it.

 

Anyway, let's keep this extremely simple: you want to be able to add another 295x2 down the road. So we should look at how much power a 295x2 can consume by itself. According to Guru3D, that can be 487W:

 

http://www.guru3d.com/articles_pages/amd_radeon_r9_295x2_review,12.html

 

Let's just call it 490W to keep it simple. So, let's add 490W to the 624W that they got for the entire system, but this 624W was pulled out of the wall outlet, this is not how much power the computer is pulling out of the PSU. So first, I need to figure out how much power the computer is pulling out of the PSU before adding 490W. So, I will assume that their PSU is 90% efficient just to keep it simple, which means I must multiply 624 by .90. The result is 561W. So, if I add 490W to 561W, I get 1051W. This means that if Guru3D had added a 2nd R9 295x2 to their test system, then a good quality-made 1200W PSU would have been plenty.

 

So, I will say to you that a good quality-made 1200W PSU should be all you will need.

 

Now, there's one question that needs to be answered by some experts, but in order for the answer to be given, we need to know what monitor you have. The question is this: would it really be worth your money to buy a 2nd R9 295x2 later on?

It's a computer!

TwoCables I think it's safe to assume his system is pulling a bit more wattage than the guru3d build. Isn't the 9590 a 220 watt chip stock? I'm figuring around 1150W for it at 80% TDP & Load counting all his drives and the cpu cooler + assuming a few fans. I would figure the 1200W would be good but could be insufficient for an overclock and high stress levels depending on the machines use. You're the PSU wizard though these are just my thoughts biggrin.gif

I worry about the heat this kind of setup is going to create, CPU temps are definitely going to be jumping up quite a bit from the heat those GPUs throw off, especially if you set up the GPU rads as intake to favor lower GPU temperatures, I'm assuming the rads are going to go in the dual 120mm front fans on that case. It's definitely something to consider, you're talking about a MONSTER amount of power in that puppy biggrin.gif

also, DDR3 1033? Are you able to run those at atleast 1600? I would think to upgrade to a higher speed kit over jumping to 16GB, I'm wondering what speed you have your current kit set to.

Their test system already has drives and fans.

 

I do see now though that I forgot to specifically say something like, "but if you want to overclock, then you might want to consider a PSU that has a larger capacity".

that leads me to believe you probably don't know what you want, and I assume in 4 or 6 years you'll have a totally different perspective. Hell, with the 390X coming out with ridiculous specs I would never buy 295X2 now, if I had the money of course. But if CF 295X2 is your plan I would NOT go lower than 1300W for sure, and that is if the cards are stock. If you're planning to OC and slide that power limit all the way up better get a 1600W. In any case, look for EVGA G2 1300W or higher, those are excellent quality and longest warranty of all.

I know that, it was really the CPU that set off the warning light for me, stock should only be a little bit more power draw then the 3960x OC used in the article, OC 9590 is really going to push the limit and an overclock on those graphics cards is uncharted territory for me. Just so he knows to consider that.

I'm in this party, I'm assuming this is for an upgrade to a 4k setup. It's hard for anybody to know what they want right now really. On the bright side, in 4-6 years a 295x will be dirt cheap to add a little extra horsepower to the machine. On the other hand, we're talking a big chunk of change in power bills over the course of that many years and I'm sure the bandwidth on GDDR5 just isn't going to cut it in 2020, especially not at such a huge wattage.. But then what is the power consumption going to be like on a 390x and how much of an edge is it really going to have, it's all just up in the air for a few more months. I would vote to get the single 295x2 and then sell it and upgrade to a 490x, which I believe is what I'm going to do.

as i said, its theorical, but now, i had some informations about how the Power is calculated on the PSU .

So, I will say to you that a good quality-made 1200W PSU should be all you will need.

i'm interested by buying a AX1200i because i want to be equiped with Corsair brand, i have the ram, the Case, the watercool, the psu, then fans smile.gif but i'm not closed to buy another brand thumb.gif

i play on a LG 23" HDMI monitor 1920x1080 ( LG 23MP55HQ ).

4K Gaming is not my priority now, but i consider play in 4k in few years, when 4K monitor will be cheaper .

I'm not an hardcore gamer and i hate the overkill in general, but if you look at the recommended setups in today's games, it's really complicated to get the game running good, even with the recommended hardware setup !

i mean 60FPS all the time MSAA 4X and Very High textures /graphics / visuals effects, i think the Radeon R9 295X2 is a good option to run many games without difficulties .

i know there is the 390X coming in june or before , but if its to get 10FPS more... : I better get the Dual GPU board in hands smile.gif

you know, i'm not a compulsive buyer who stays tuned into what graphics cards will come out, and then buy it .

no, I did not plan to overclock the R9 295x2 because i think the frequency (1020MHz) is ok to play GTA V in HD (1080P), or Just cause 3 , then Far cry 4 , and all the games they will come out in 2016/2017

so, now i know that having a Good PSU > 1200W is a thing to consider if i want to do CF-X.

i was searching for how many watts and Amps the FX-9590 CPU consume ? is it really 220W ?

i have smetimes errors in windows like "Kernel Power error" ... but my PSU is not used at 100% . i think its about 80% Usage .

in HW Monitor, i have 77W MAX when i am under unigine benchmark such as valley or when i play GTA V , i can't belive the system is just pulling 75W from the PSU when playing or benchmarking...

i'm Ok with you, and yes, i see as you see, no ones knows what he wants, i know i want quality built PC and high perfs !

in my old pc ( i mean old by before having what i have now ) with 8GB ram Radeon HD6950 and AMD Phenom II 955, i was able to play games, and do some video editing easily , but games were not playable in HD :/ . i had this setup for at least 4 years ! so assuming i'm interested by having the 295X2 in the next week , i want just to get a little extra perfs, i plan to buy another one later in 5 years,

then in 2020 i will see what is new, and what needs to be upgraded .
in some years, i think the R9 295x2 will cost a little lower, i had it for €699 . in other sites in france we can find them at €750 !!!

i want to take a single Card now , but also a Good PSU , in case of Wild CF-X with 2X 925X2 ... or if i upgrade with another GFX card .

i do not want to overclock, definityvely, its not necessary on this AMD FX 9590 !
i use my computer to play games first and to edit footages taken from my gopro . sometimes i do After effects work, i do application developpement too.

It's definitely something to consider, you're talking about a MONSTER amount of power in that puppy biggrin.gif

yes i planned to put the fan on the rear of the case, inside, but leave the two fans in the front bring fresh air . if i have a CF-X i will change the placing of rads, and stick them to the front of the case where there is the 120MM places.

the heat is not a problem for me, its good in winter, but i have conditioned air in my room for the summer tongue.gif .

also, DDR3 1033? Are you able to run those at atleast 1600? I would think to upgrade to a higher speed kit over jumping to 16GB, I'm wondering what speed you have your current kit set to.

yes, I did a mistake, its in facts 1600 MHz , 2x4GB , if i CF-X i will jump to 16GB .

so you are saying that My 750W Corsair will be ok to use in a first sime a single 295X2 ?

 

I wasn't trying to, but yes it is plenty. I mean, look at its 12V capacity alone! ;) It's way more than just 54A (which is 624W). Isn't it at 62A (744W)?

It's too bad that Corsair doesn't make motherboards. You could have an all-Corsair computer.

 

Corsair's PSUs are usually a little overpriced though due to the brand name. Check this out: http://www.overclock.net/t/183810/faq-recommended-power-supplies There are many good non-Corsair PSUs.

One thing that you can do is make a new thread on here just for help in selecting a good video card. You'd mention in the thread what you have for a video card and what games you play as well as what you want for performance. Who knows, you might find that you don't even need the 295x2. I wouldn't know though.

as i said, its theorical, but now, i had some informations about how the Power is calculated on the PSU .

you know, i'm not a compulsive buyer who stays tuned into what graphics cards will come out, and then buy it .

no, I did not plan to overclock the R9 295x2 because i think the frequency (1020MHz) is ok to play GTA V in HD (1080P), or Just cause 3 , then Far cry 4 , and all the games they will come out in 2016/2017

so, now i know that having a Good PSU > 1200W is a thing to consider if i want to do CF-X.

 

Since you won't be overclocking anything, a good quality-made 1200W PSU would be all that yuo'd ever need if you had two 295x2s in this system.

It has a TDP of 220W, so technically, it can pull that much.

Kernal Power Error is simply due to Windows not being shut down properly. It has absolutely nothing to do with actual power issues.

 

Your computer is pulling no more than about 400-450W while gaming. So, that's really only about 54-60%. Again, that's while gaming.

I would say that 77W is just the CPU and nothing else.

then in 2020 i will see what is new, and what needs to be upgraded .
in some years, i think the R9 295x2 will cost a little lower, i had it for €699 . in other sites in france we can find them at €750 !!!

 

In 5 years, you probably won't be able to find anyone selling it. In 5 years, you won't want to even touch a card like the 295x2. It'll seem like ancient and super-slow technology. Think back to the best cards that were out 5 years ago. Would you want to use one of those today? Heck no. ;)

the part that stands out to me is the 1080P resolution. A single 290X is way more then enough horsepower to max anything out (short of SSAA) on 1080P and provide a solid 60 FPS. The difference between a 6950 and a 290X is MASSIVE.

For my system: I'm using a 280X while I'm still gaming on a 1080 screen and really nothing touches it, GTAV stays quite solid at 60 FPS minus random drops which seem to hit every card in it. I also have another rig with a modestly overclocked 7950 that can take GTAV but I have a cpu bottleneck on it. Metro Last Light Redux runs maxed (minus SSAA) on the 280x as well. Aside from that every other game I play runs rock solid at 60 FPS maxed at 1080P on both cards, this also includes playing lower demand games like Borderlands 2 in eyefinity on 3 1080P monitors. I have no trouble with either system on any of the games I've tried and I have no plans of upgrading GPUs until I go to higher resolution. 290X is a large step up over the 7950 and 280X

I would honestly suggest a 290X, 8GB model if you really want to make it last (in case games get really lax with textures, but I don't really see the 4gb version not being enough for 1080P). 290X even performs at 1440P very well. That will buy you plenty of time to save your money and upgrade when you decide to go to a 4k display. I don't think now is the time to invest big money unless you have a need to drive a 4k display NOW. GDDR5 is being phased out, 390X will be using HBM (High Bandwidth Memory), and in 2016 Nvidia Pascal will be using HBM2 on a die shrink, and then the 490x will be showing it's head potentially late next year with HBM2. Make sure you read up on HBM if you haven't heard of i and be aware that we will be finally leaving 28nm gpus behind in 2016.

If there are specific games you have in mind, just look up benchmarks for them or ask. I think 290x is the best option, you wont have to waste money on a behemoth power supply to get the same performance at 1080P, save it all for when you get a 4k monitor, if that's in 2016-2017 there will be single card solutions that will take care of 4k and they will likely pull well less than 1/4 of the power draw of 295x2 CF. Smaller power bill, less heat in your system. That's how I would do it.

Do old pipes really give the sweetest smoke ?

i mean , i not embarrased by having an old technology on my PC, i tested out GTA V on my HD 6950, its a bit laggy, but by doing some parameters and without V Sync i'm able to run the game but near 30~45FPS in middle params , so i can play it, but i have the game already on XBOX one, and i can ensure you, i'm not able to play online with friends on my pc, at constant 60 FPS, i must reduce parameters to get the gauge in green : 1500/3000 MB (for thoses who knows what i mean in GTA V )

yes its a 62A so 62*12 = 744W thumb.gif .

i will take a several look at these PSU's , but if i want to CF-X theses i will take at least 1200W if you say that is ok smile.gif

basically , i was looking for a CF-X with 280 ( thats why i have a 750W ) but on the benchmarks from todays games,the R9 280 was not listed ... i'm not sure i did ithe good buy :/
But anyway, why not post just to take informations ?

Ok for the error, some times my computer gets off by itself, without doing anything . (idle)

maybe i forget to say it : i have Two screens on my desktop :

1 LG running at 1920 x 1080
1 iiyama PL1908W running at 1650x1050


when i play some games i have Skype and temp HW monitor on the other screen . i will take a look at the stats while gaming.

i was looking at the GFX cards, for the same price in CF-X you have the R9 295X2 ( 4GB+4GB cards )

playing at MSAA X8 min + Very High textures, for me could be a good experience, that's why i'm interested by taking CF-X 295x2 .

i have the XBOX one too, but i keep the console to play exclusive games such as Halo, Forza Horizon 2 and others exclusivity titles : idarb, chariot, ori and the blind forest .

Now the big aim for me is to play Games with high Framerate , solid 60FPS (ultimate) experience .


to sum up :

- i'm looking for great/very high performances i have the latest CPU, i dont want to change it tomorrow but maybe in 6 years .
- i'm looking for great render times in Vegas pro / Premiere pro CC / After effects CC

i dont want to get intel processors because they are too expensive for me , (half price by buying a high end 8-core by AMD ) and doing the same job ( Ok AMD is definitively heater than intel processors ).


but one more time, thanks guy's i have understood some things about PSU's , and others tips'n'tricks

i agree with you, i'm pretty sure there will be new cards later this year or near 2017/2018 , but how much ? same price than actual GFX cards ?

have a look at here, (its euros prices) by setting the filters to R9 290X you have min : €324,95 and max €479,99 so imagine a CF-X at this price, the R9 295x2 is cheaper ...

when i launched GTAV for the fisrt time, i was wondering what the hell is doing my R9 280 ? that's why i was wondering about a CF-X in 280! and then a Bi-GPU Card
