Corsair VX450W enough?

[Paraipan]

Hi, I've got this solid PSU since 2009 and now I need to push it a little bit more.
I have a great offfer for GTX 760, HD7950 and HD7870.

My system specs:
i7 4790 + Corsair H80i
8 GB RAM
One HDD
4 120mm fans


Will my PSU be enough for these cards?I've seen a guy with an i5 3570k, hd7950 working just fine with this psu.
I will change it but not now, in the next 2-3 months.

Thanks

You have more than enough power to run your system with the 7950 (the most power hungry out of the group), and overclock at the same time.

I might consider the r9 270x too as long as they have almost the same TDP(hd7870). It will be ok with connectors?

Theres no way I'd run that on the PSU.. esp if you plan to OC, and add extras.

According to the PSU calculators yes it appears you'll be OK. 33A on your 12v is just enough for that i7 and 7950. If you OC both the cpu and gpu you'll be in marginal territory.

My config draws around 400W from the outlet, so that PSU should be enough.
