Hi can you give me some advice on what to pick between these two great power supply? Any suggestions, make sure it is on the same price range.

My specs:
Intel Pentium G3220
Gigabyte GA H81M-DS2
Sapphire R7 260X 2GB/128bit OCed
G.Skill Ripjaws X 4GBx2 1600 CL7
Seagate Barracuda 320GB SATA

Neither of those two power supplies are Intel Haswell compatible.

Suggestions don't help if they're not available in the country that you live in.

Please specify your budget range and a link to vendors in your country that you use.

Also specify whether or not you may consider running two Radeon R7 260X in 2-way CrossFire mode in the future.

For a system using a single Radeon R7 260X graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 26 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

When I look at the cross load test for the Aerocool Strike-X 600W where the +12V rail is lightly loaded and the +5V rail is more heavily loaded (i.e. like what would happen during Haswell's C6/C7 power state) I see that the +12V rail's voltage will go out of spec (i.e. rise to 12.98V when the maximum allowed by the ATX12V specs is +12.6V).

Another problem with the Aerocool Strike-X 600W is that the +5V rail will go out of spec (i.e. rise to +5.27V when the maximum allowed by the ATX12V specs is +5.25V) when the +12V rail is heavily loaded and the +3.3V and +5V rails are lightly loaded.

I don't blindly believe what a manufacturer claims without seeing empirical data to back it up. Just based on its electrical performance alone would tell me to not recommend the Aerocool Strike-X 600W.

Corsair states "Likely compatible — currently validating" for their current VS Series models. This status hasn't changed in about a year so it isn't Haswell Compatible.

If a PSU is 100% Haswell Compatible then all of its specifications will remain within the ATX12V Power Supply Design specifications during Haswell's C6/C7 power state.
