Im building a budget pc, here in Argentina prices are really really high for pc components, so im building this:

FX6100 OC to 3.7
16gb Hyper X 1866
x2 1TB Barracuda
RX 460 2gb (plan to CF it in a future, i know is a low end card but RX 470 is out of my budget)

Im between these PSU:

EVGA 430W 80 PLUS
Thermaltake 500w TR2
XFX XT 400w
Sentey Xcore Power XCP530-ts
500w Sentey Snp 500 80 Plus certified 37a
(i have been using Sentey 600w psu with hd6870 for 4 years, 6870 OC and never had any problem, i read that sentey is bad psu but i dunno, i never experimented any issue...)
Seasonic 400w ss400-es

460 CF with a 95w cpu +OC. For a quality psu, 450w. For an average psu 500w. For a low grade psu 600w. What this leaves you is many options. There are quite a few very good 520w-550w psus out there, Antec HCG-M, Seasonic S/M 12-II, XFX TS or Pro, the new Corsair CXM, older Corsair HX, Evga GS, G2, B2. All of which are at least 80+ Bronze, some Gold. Shop around local parts stores, online e-tailers like Amazon etc. You'll find something decent at a decent price somewhere. Until then, your current 600w sentey is good enough, being large enough not to see any stress at any time. It's not the best unit, but it'll work.

The rx460 basically recommended a 380w psu. So out of that list only the Seasonic applies. The xfx is next to worthless, it's the XT version, not built by Seasonic. The rest I wouldn't trust to be decent paperweights. However, 460 CF requires a 450w psu, and with a 95w cpu, I'd be inclined not to go lower. The HD 6870 is recommended 500w psu, so with a realist 300w-350w system, running a 600w psu leaves plenty of room and the psu is never stressed even close to limits, where lower rated units like the sentey usually run into issues. Honestly, I'd keep your current psu, it'll swap easily, this'll give you time to save up for a reliable psu in the size you'll need. The extra cash saved might be enough to enable the purchase of the 470, saving you more money since you won't then need a second card in CF.

Yes it does. You can give it a try if you want, I bet it will work but like Is aid you will be pushing a 400watt psu quite hard with 460 crossfire. If you do decide to do I would make sure the psu has plenty of ventilation because its going to run hot.

You can go for a cheap psu like the senty with higher wattage but personally I would rather push a quality lower wattage psu hard that I know has the proper protection circuitry should anything go wrong, than push a cheap bigger power supply somewhat hard. Those psu's are cheap for a reason, they may work fine for years but the day it dies it may take the rest of your computer with it.
