Hey,

Since I don't have much experience with power ( e.g. I can't figure out by myself if a specific power supply could run a computer with OC'ed CPU ) I'm asking here if the Corsair CX-500 or even the XFX Pro 450W Core Edition is able to run the gaming rig below. The machine will be mainly for gaming in maximum settings I'm able to play with decent FPS but also for programming and some 3D modelling.

Case: Nox Zen
CPU: AMD FX-8320 @ 4.2-4.4GHz
Mobo: ASRock 970 Extreme3
GPU: Sapphire Radeon HD 7850 Dual-X ( I want to put this GPU to its maximum )
Memory: Patriot Viper 3 Series DDR3 1600MHz CL9 2x4GB

I'll also add a 1TB HDD and of course connect peripherals and that's it.

Thank you :)
 


Hi - Brett is correct.
Are you located in the US? If so, you can get the XFX pro 550
for $40 net after promo & mir. You will have headroom for
OC & 3d modeling.

Nop, I live in Portugal and here I can get LC Power 560W v2.3 for 49,70€, XFX Pro 450W Core Edition for 49,90€ and the Corsair CX500 for 47,90€ since it's in promo ( I don't trust much that LC Power, only in Gold series but these cost much more ).

The reason why I did that post is because I thought FX-8320 would consume a lot of power but I guess I can also do some change on voltages to decrease that.
 


Hi - Sapphire recommends 500w min PSU for the 7850.
However, that is inflated to account for PSU's with
false power specs. You will be to run that system
with the XFX 450 or the cx500, as the system will draw less than 300w
without OC. You are prob OK with some OC.

Well, I guess I'll still stick with the Corsair CX500 because it gives 456W max power while XFX Pro 450W Core Edition provides 408W only.

I hope I don't *** everything up when OC'ing lol

id say get the corsair hx750 plenty of power even if you decide to crossfire later on its modular no extra wire to rub fans or clog airflow. good efficacy rating.

Unfortunately the Corsair HX750 is out of my budget, if I could I would buy it for sure. I'll never do crossfire/SLI since they give more problems than performance and uses much more power.

I guess 456W is enough for that machine, though. Isn't it?

450 of constant power yes 450 max output no id say your would risk burning it up with long gaming sessions

Yeah, I meant 456W of max DC Output on the 12V rail.

How much watts would it be necessary?

I'll post here the link of one power supply even if it's not in english: http://www.pcdiga.com/2/4135/Fonte-LC-Power-650W-LC6650GP3-V2-3-140mm

I just don't know if this PSU is that good as it says. It says it's rated 80 Plus Bronze but some of them are too but suck. Its max DC output is 624W but since it has 88,52% of efficiency that means the maximum is 552W?
 


Hi again - Plz stick with one of the two "quality brand" choices you
have been looking at. "No name" brands very often don't meet publ specs,
and are usually more trouble than they are worth.

Either one of the XFX or Corsair will work with your system.

Stay away from "unknown brands"

LC Power isn't unknown. Actually, they're very known in Portugal. They aren't that good, though - Only the Gold Series is good.

So what? One says that 456W isn't enough, other says it is enough. I'm confused now.

I ain't going to upgrade in 5 years so I guess a FX-8320 will be better for me also cuz I'll be programming & doing some little 3d modelling.

My two choices are:

Case - Nox Zen ( 24,6€ > PCDiga )
CPU - Intel Core i5-3350p ( 165€ > PCDiga )
Mobo - MSI B75MA-P45 ( 62€ > PCDiga )
GPU - Sapphire Radeon HD 7850 Dual-X ( 155,99€ )
Memory - Patriot Viper 3 Series DDR3 CL9 2x4GB ( 35,9€ )
PSU - Corsair CX500 ( 47,9€ )
Fan - Artic Cooling F12PWM ( 5,9€ )

Price: 497,29€

And:

Case - Nox Zen ( 24,6€ > PCDiga )
CPU - AMD FX-8320 ( 165,9€ > PCDiga )
Mobo - ASRock 970 Extreme3 ( 75,9€ > Pixmania )
GPU - Sapphire Radeon HD 7850 Dual-X ( 155,99€ > Pixmania )
Memory - Patriot Viper 3 DDR3 CL9 2x4GB ( 35,9€ > Pixmania )
PSU - Corsair CX500 ( 47,9€ > PCDiga )
Fan - Artic Cooling F12PWM ( 5,9€ > PCDiga )

Price: 512,09€

My budget is around 500-520€ and I still have to pay 7,99 or 13,99€ for shipping so IDK anymore which one to stick with. i5-3470 can be better at stock, but then if I OC the FX-8320 it will outperform the i5.
