Is my build good?

[DaFunk]

Mobo: Asrock H81M-HDS
RAM: Crucial DDR3 Ballistix Sport 2x4GB 1600 C9
CPU: Intel Core i5 4460
GPU: MSI RADEON R9 280X GAMING 3G
PSU: Seasonic M12II Evo 520W
HDD: Western Digital Blue WD10EZEX 1TB
Case: Zalman Z1
Optical Drive: LG DVD+/-R/RW GH24NSC0.AUAA10B S-ATA black OEM
OS: WIndows 8.1

Should I wait with the purchase of the GPU since the 300 series has just been released and there might be a price drop?

Also, the PSU should provide enough wattage but I have heard some people say that the amps and voltage on the power rails need to be good enough for the build. I don't even know what this means to be honest so could anybody also tell me if this is the case with this build if it isn't too much trouble?

I would consider a difference PSU, perhaps one that has a strong single rail rather than a multirail setup.

But what exactly is the difference between a PSU with a strong single rail and one with a multirail setup?
Do you think there would be many problems if I decided to go with the PSU I posted?

 

[utgotye]

The difference is that the 12V rail is not split up over multiple rails, allowing your current to be concentrated.

Problems? Sure, it might not start or when it reaches a high enough load it could spontaneously shut down. That is a quality PSU but it's not what I would use for that particular setup, especially if you think you are going to be doing any upgrading in the future. AMD cards in particular are quite power hungry.

Looks like a great build! And I personally wouldn't wait for the release of the 300 series because the prices most likely will not drop a extreme amount.

Thanks! All I have to change is the PSU because apparently a single rail PSU is more suited for a powerhungry build like this than a multirail one.

That is a quality PSU, but I would recommend bumping up to the 620w version instead. Dual rail vs single rail doesn't really matter all that much, in your situation. I would wait on the GPU also.

I calculated the wattage usage and even at 100% load it was around 490W, are you sure I should take one with more power?

 

[logainofhades]

Yea, a 620w would make more sense, and the price generally isn't much different. You do not want to use too much of your PSU's rated wattage. As capacitors age, strength of the psu can diminish, also they are not as efficient, when loaded so high.
