What psu should i get for gtx 970 and i5 4460?

Solution
Will dont worry ! H81 motherboards usually have PCI-E 2.0 slots but all gen 3.0 cards work in gen 2.0 slots - PCIE is backward compatible . Just make sure your mobo has x16 PCI-E slot - 99.9999% sure it has

i would get i5 4590 for better performance and H97 motherboard-ATX or mATX .

All of the above will allow light overclocking and the single card, but if you intend to do SLI or a hard overclock, then you will need more wattage headroom.
