More about : 280x 500w psu

it's a coin flip, it might if it's a real good quality psu. but it would be best to get a 600W+ one

I don't think so, it will probably cause you crashes on full load.

At best the PSU will work under extreme load while gaming and will not last too long.
At worst the PSU will fail and cause damage to other components.
Of course without knowing the rest of your specifications that's the best answer i can give:)

The QUICK ANSWER is that you if have enough 6-pin/8-pin PCIe power connectors. If so, you "should" be fine.

The LONG ANSWER depends on your CPU, if you overclock it, as well as the efficiency of the PSU and its 12V available amperage (which you listed thanks). The CPU shares the 12V power.

The QUALITY of the power supply also matters for stability especially if pushing the limit.

So my answer is THIS:
1) If you have the proper 6-pin/8-pin connectors you should be fine provided the CPU isn't overclocked (it may work but I don't know what CPU you have).

2) If it's not a quality power supply I'd recommend replacing it regardless.

so could you tell us the brand/model of the psu?

my psu has 2x 6+2 power connectors...of course the cpu wont be overclocked.all will be stock

It would have to be an excellent PSU to handle the 280x even though the rest of your system requires fairly low wattage.
The make and model would help as Laviniu Campean asked.
If i were you and wanted to keep the PSU i would consider an AMD 270x instead

i have seen to several benchmarks that 770 consumes 40-50watts less than r9 280x...what about that????
i also think that i dont think i will use this psu for a long time...if i buy such a graphics card, i will buy a new psu 5 months later

I wouldn't risk running that card with that PSU. It's your decision of course but that is my opinion.
My recommendation is a different GPU like the AMD 270x or the Nvidia GTX 760

would be fine running a 280x with a 500w QUALITY psu, so long as you dont have an 8 core/overclocked cpu, and plan to oc the 280x.

It should be fine.

Your CPU can't be overclocked and has a TDP of 84W which means it will use LESS than this amount (Thermal Design Point).

The worst-case scenario using Furmark for an overclocked Asus R9-280X is 300W.

That comes to 384W and the 12V rails support up to 408W.

Again, that's a worst-case scenario which we don't max out though it's likely during a game we'd never see above about 340W.

Plus, I repeat, your Power Supply was designed to handle a card of your specs and an efficient, non-overclocked CPU is the EXACT scenario you have.

If the Power Supply dies then it's due to a manufacturing error, or a design error, but as for the parts used we are within SPEC.

If your PSU still under warranty and you blew that up with the new video card you can always send that PSU back to where it comes from and tell the RMA department what you have and they will replace you a better one ;)

R9-280X a rip-off?

I just looked up this card at Newegg. Aside from the fact it's basically OUT OF STOCK, the price I saw was $400. WTF?

It's basically a rebadged HD7970 GHz card: http://www.tomshardware.com/reviews/radeon-r9-280x-r9-2...

*You can get a 4GB GTX770 from Gigabyte with great reviews for $360 (or a cheaper 2GB card for $330):
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The R9-280X and GTX770 are very similar for raw performance though I think apples-to-apples the GTX770 wins slightly at same GPU frequency: http://www.guru3d.com/articles_pages/msi_radeon_r9_280x...

So the GTX770 is cheaper (even the 4GB model). Aside from Mantle which will have minimal support, I don't see much advantage to the 280X card.

NVidia's GTX770 is again cheaper, and has features you may or may not care about:
- PHYSX
- Shadowplay (recording)
- Shield streaming (integration with SteamOS box in future?)
- G-Sync (future monitor support for minimal stutter)

So my recommendation is either a $330 GTX770 with 2GB or the $360 version with 4GB if VRAM is a concern.

it seems the US has received a price hike to do with the lack of stock, the 280x could be had for near $300 only a few weeks ago.

yeahhhh.....i dont think i will buy r9 280x...it consumes lot of power also...i will probably buy 770 msi gaming(295 euro) or 7970 xfx(925mhz-money is a matter)275euro

the 280x consumes about the same amount of power as the 7970 (as its a rebadged version of it) and the 770 consumes about the same also.

Change of plans...i will buy a 7970 double dissipation...its 260$in my country....it also states that requires 500w psu.....but i want to ask something,is it alot worse than 770,if so how many fps in for example BF4?????

That's pushing it. 600+ Watt PSU and you'll be fine.
