PSU for my Setup

[ThiagoKnittel]

My setup is:
MotherBoard: Asus p8H61
RAM : 2x 4GB Corsair CMV4GX3M1A1333C9
CPU : Intel Core i3-2100
GPU : NVIDEA GTS 250
PSU : Cooler Master RS-650-PCAR-E3 (650W)
2x HD SATA 3 7600 RPM
Windows 10 64 bit Professional

I'm buying a GTX 960 2GB and i intend to buy a new PSU. Will a PSU XFX ATX 550W Core Edition P1-550S-XXB9 or a Antec VP-450 be enough for this setup?

It is enough to power your system, but just in case, I would recommend 600w+ power supplies.

While Antec VP 450w can easily power up a single gtx 960,i'd still go for a xfx 550w if i had the choice for more headroom and future upgrades.
Do Note that 550w is way more than enough for your setup,with the gtx 960.
Whereas Antec 450w is enough for your setup,with the gtx 960.

is OCZ ATX 600W Silencer MK II a good PSU?
It's almost the same price as the ones i've cited but its 600W.

 

[SPgamer007]

Nope.Unless you wan't to look for a new psu anytime soon.
While it's 600w and cheap,it's not trusted one.And you don't need those extra 150w for now.

Is the XFX ATX 550W Core Edition P1-550S-XXB9 a trusted one?

 

[SPgamer007]

Trusted one.
Btw,here's one of the best 550w units out there,for just 50 bucks.

I'm in Brazil so my options are quite limited. I'm thinking of buying one Antec VP-550 because XFX ATX 550W went out of stock.
Is this good?
It's a little more expensive than the Antec VP-440 but i'm thinking it's extra watts can be utilized in future upgrades.

 

[SPgamer007]

All VP PSUs are good.

 

[Dark Lord of Tech]

VP are good?

 

[ThiagoKnittel]

They are tier 3 on this list : http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
so they are supposed to be safe and stable.
Also I found this review on the antec VP 450 saying that it is a good quality PSU :
