290x with 650W PSU?

[Ravenas]

Ok first and foremost I know what the power requirements are... The reason I am asking is mainly because I just read an article on Guru3D speaking on this subject. The article I am referring to can be found here:

http://www.guru3d.com/articles_pages/radeon_r9_290x_crossfire_vs_sli_review_benchmarks,4.html

Here is Guru3D's power supply recommendation:

• AMD Radeon R9 290X - On your average system the card requires you to have a 550~600 Watt power supply unit.
• AMD Radeon R9 290X Crossfire - On your average system the cards require you to have a 800 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina. There are many good PSUs out there, please do have a look at our many PSU reviews as we have loads of recommended PSUs for you to check out in there. What would happen if your PSU can't cope with the load:

Given the above reference, does anyone have any experience running a 290x on a 650W PSU?

the R9 290 will peak at 300W your CPU is in the 280W area 1HDD = 5 to 10W 2 sticks of ram 6W every fan 3W and the mobo does 20 to 50W so you'll be cutting it real close on your setup unless you drop the FX8350's OC by around 300mhz.
As for actual knowledge of some doing that I have none

You can do it if you have a high quality 650w. Depends on the rest of the system too. Your FX8350 at 5.0GHZ is probably pulling 200w+ alone.

I don't have experience with a 290X, but as an enthusiast with a bulldozer and a fairly high end PC, i've seen my poweruse peak at 620 Watts. This was with really heavy overclocks on both CPU and GPU while running prime95 and furmark so I suppose absolute worst case but I'd imagine that the 290X has the potential to use even more power than my 7950. Soo, it might be cutting it close. unless you dont plan on overclocking a whole lot(unlikely i think =D) then you'll prolly be safer with a higher wattage PSU.

It uses quite a bit more power than your 7950.

Exactly! the difference might be a bit smaller when both are overclocked to the limit, although i'm not too sure. What i am sure of though is that my CPU alone can get the poweruse up to about 460Watts lol. doubt piledrivers get that high so that might mitigate the poweruse compared to my system.

 

[Ravenas]

Hmm... Well I think I may just buy a 750W. I don't like cutting things close. Just hoped someone might have some first hand experience with their build.

Well you just missed a sale on Newegg for a Seasonic Platinum 760w earlier this week for like $139 or something I think.

My Chieftec nitro 650W 88+ (52a) can maintain stability with a OC'ed 580GTX @ 900mhz 1.1v and 4770k @ 4.6ghz or 4.7ghz 1.28v..

lol i bet my left limb that oc'ed 580gtx consumes a lot more then 290x at stock

yeah but the OC 4770k consumes quite a bit less then an OC 8350.

Is that PSU equipped with one 12v rail?

 

[TheHunter]

Hm not really sure, I think its single 52A rail.

My old 600W died after 5years, so i had to make a quick "cheap 100€" replacement, this one looked perfect

To OP, if you drop your 8350 OC to say 4.2 to 4.4 and not OC the 290X, you might be able to get away with it.

Yeah I agree with you. I was doing the math, adding up my power draw sum, and it looks like I could get away with it. Worst that could happen is I would have to purchase a new PSU.

 

[leeb2013]

I've seen 720W benchmarking with an i5-3570k @ 4.8GHz and 2x 7950, so I think 650w would be close if you o/c'd and pushed your system.

 

[Durvelle27]

Definitely drop OC if you want to use the 650W. I have a Corsair TX850 and had my 8350 @5GHz 1.5v & R9 290 @1215/1450 1.35v and I have tripped OCP three times

Just to let you know when I was deciding on CF or single card, I played FC3 and BF3 for about an hour with my FX 8320 OCed to 4.2 and 2 X 7870 both OCed to 1150 core, whole system alone sucked 550w (according to Kill-A-Watt), Everybody hates oh run away keep really far don't touch with a stick brand ULTRA X3 600W didn't give up. Finally settled for single 7950 OCed to 1150. Now my system when playing BF4 peaks around 420w.

According to MSI, the recommendation for a 290x is a 33A, 600w PSU minimum. Keep in mind that's for total system power, not just the card, and such recs are always listed a bit conservatively to account for varying quality and efficiency in PSUs.

Those estimates are always high. Its will work as long as its a quality PSU. easily

It meets the amperage requirements and the wattage. Current and power are fine.
