Hi, this is something i wanna buy:
CPU: i7700 4 cores 3.6-4.2ghz
MOTHERBOARD:gygabyte ga z270 gaming k3
RAM: 16gb ddr4
SSD:250GB sk hynix SL301
HardDrive : 1TB firecuda sshd hybrid drive
GPU: geforge gtx1070 8gb
PSU: Corsair CX650 80+ bronze 650W

Do i need a better psu for the cpu and that gpu? I can chose from the one listed above, FSP silver 80+ 700W or EVGA 80+ bronze 700W

Second thing i want to know : would you recommend me to downgrade from this motherboard and get an asus prime b250-a(this is all i could find in a stock near me).Is this one the asusprimeb250-a gonna be compatible with everything i listed above?Performance, how is it gonna do compared to the gygabyte z270?

Last thing: I got an ssd 250gb where i plan to install the os and some games, even though the hard drive i want is hybrid.Now here i am not sure, does this hybrid drive act exactly like the ssd?So, should i drop the ssd and just keep the hard drive and spare me some bucks?Or ssd are faster than hybrid ssharddrives?
 
1. The b250 prime is fine mate if it's substantially cheaper, it covers all the bases & will have no issue with a locked i7

2. The CX 650 (should be the 2016/17 silver black labelled model?) Is fine , absolutely better than that evga , probably better than the fsp too (can't tell without the model number) - stick with the corsair is my advice for that reason.

3. While the firecuda is a decent hybrid drive its no match for a really ssd.
Keep the ssd in there , swap the firecuda out for a decent standard 7200rpm drive , a hybrid drive doesn't really benefit anything as a secondary drive for games etc - you're spending extra for nothing there IMO
A western digital blue , any Toshiba 7200rpm or a standard Seagate barracuda if you're pushed.
Should save you $50 or so.

power supply is fine. grey and black label? yeah. just fine.
the z270 boards are the enthusiast boards, overclocking features, extra slots and ports, etc.. if these things are unimportant...
A hybrid is nothing like an SSD, it does have an "SSD" on-board but it is tiny.
The OS being housed on the SSD will greatly speed things up, the applications installed there will be faster too.

Which would be good? Also, should i get the gygabyte motherboard or the b250-a i think i can afford to spend on it, cause it only saves me like 50$
