Old trusty corsair lol. ($25 after mail in rebate too)

Or if you don't want to deal with the cables, The modular version for $5 more ($30 after rebate)

CORSAIR Builder Series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply

Lol I had the same PSU in mind xD I just want to know if it's silent and enough to power my build ?

 

[lunyone]

I would believe your going to have other parts that might be noisier than the PSU, but I don't own one to tell you for sure.

Mmm ok and what's the difference between this one and the modular one ? Less cables ?

You can't go wrong with a Corsair PSU.

I´d go with at least 500W if you want to overclock later.

XFX 550W PRO550W Core Edition http://us.ncix.com/products/?usaffiliateid=1000031504&sku=59615&vpn=P1550SXXB9&manufacture=XFX&promoid=1257

It is $54.99 after mail in rebate, and made by Seasonic!

I would rather spend the extra ~$20 on a better GPU, like the 7790 or even up to 7850 with the Corsair CX 430w PSU.

 

[iAmJimbo]

I was thinking maybe using this GPU instead if it was worth it: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127726

Both HD 7770 and HD 7790 (and the HD 7850) need around 500W, of a good quality PSU, but you can try it with a 450W PSU.

 

[iAmJimbo]

How about this PSU ? http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027

The power ratings on the GPUs are mostly utter crap.... they "recommend" that because MOST of these gpus get bunched up with completely shit power supplies in pre-built PCs from the OEM builders....

the 7790 has a TDP of 85w and the 7770 has a TDP of 80w.... Which a PCI-E 3.0 x16 slot and a 6 pin connector can more than provide.... (the specs says that the corsair cx430 can provide 32 amps on the 12V rail

Mmm ok and what's the difference between this one and the modular one ? Less cables ?

Modular means that on you ONLY need to plug in the cables you need. there should be a individual cable plug for each cable and a bundle of cables for basic cables (24 pin, 8 pin (splits into the 4 pin for the motherboard)) on the back of the PSU

If your not OC'ing the Corsair CX 430w PSU can easily handle up to 7850 or GTX 660. Obviously if you want more upgrade room than the Corsair CX 500w PSU would give you that extra upgrade room.
