Good PSU for high-end gaming

lazarba · May 3, 2014

I want a PSU that will last for years to come. There is a chance that I will go Crossfore in some years. So, I am looking for a PSU of at least 800 W up to 1000W ( it's enough, right?). I have mostly looked into the Corsair ones that seem very nice ( Ax 860, Rm 1000 ). But I know there are other quality brands as well ( EVGA , Seasonic etc ) so I want your opinion as well. All reccomendations welcome !

We need to know the rest of your build first, but nothing wrong with corsair. xfx is very competitive also.

As you wish kind sir :
i7 2600k 3.4Ghz
2x4GB XMS DDR3
Gigabyte z68 Mobo
1 HDD
1 SSD
and some extra stuff like an xbox 360 controlller, mouse , keyboard , optical drives etc.
I will get a R9 290 after the PSU and maybe a second one in the future.

This is what you have already bought I think. It looks like a great build.
Okay that looks great.
Here's an article about xfire 290s from a while ago. IT is a good bet to wait to use both for a little while.

For a system using two Radeon R9 290 graphics cards in 2-way CrossFireX mode a minimum of a 850 Watt or greater system power supply is recommended. The power supply should also have a maximum combined +12 Volt continuous current rating of 65 Amps or greater and have at least two 6-pin and two 8-pin PCI Express supplementary power connectors.
Although each card maxes at 230W in game. This is around 460 watts together + the power of the cpu and other components. . I would say the xfx 750 watt may be possible but overclocking may push to get a 850 watt system. Put the orgiinal system in pc part picker to find the total watts already.

So you think that if in the future I get a second one ( probably will be something less that 290, maybe 280x power requirement-wise ) an AX 860 will be able to handle that? ( The guy below ,which I thank , said yes. Just asking for your opinion as well .)

At 100% usage I get a 231 as minimum and a 281 reccomended

In what gaming, or testing. Furmark brings it to 300 but no game goes above 230 usually. That is surprising. Is this your personal measuring.

Nono! This is what you asked me to do. PC part picker, selected my rig WITHOUT the GPU ofc. This is what my PC consumes without a GPU.

The corsair AX 860 would be perfect for dual r9 290xs. Another good option is the Seasonic X-850.
