Which power supply?

[WooZ]

I am thinking to sel my current system, but current power supply and graphics card I will keep for new build.

Will 400W be enough to power Dual Core E6300 @2.8GHz and HD 7770? Psu calculator say it will be enough but AMD for HD7770 recommends 500W.
And he will not overclock cpu or gpu.

And which power supply you suggest under 80$ ? For now I am looking on Corsair CX430W or Chieftec 500W.

Yes, but make sure you get a quality PSU. Something from Corsair primarily.

if the card recommends a 500watt min then NO your 400watter will not be enough. and I'd stay clear of bargain brand pus's if you want reliability.

i´d have a look for a 500w psu

maybe this one

But sometimes recommendations are higher than need.

In all honesty, I think AMD are just trying to cover themselves here. There are a lot of cheap, and i mean really cheap, 500w PSUs which won't even output 400w.
Corsair are always a good bet, as their PSUs shall always output what they say they will.

So... That means Corsair CX430W will be enough?

Personally, I would say you would be fine as it's a relatively low end GPU and a low end CPU as well.
But, you may want to get a bigger PSU for upgrades in the future.

y'all always seem to miss the point of efficiency ratings imho. Just because they build a psu that outputs more than the rated doesnt mean its good to use beyond its rated specs. Doing a psu beyond the rated specs means you've gone well past its 100% rated spec and therefore its working hard to keep things stable. While getting say a 600watt psu for a 500watt recommended system makes the psu work less thereby possibly lasting longer than expected. I will always preach find what ya want and go a min of 20% higher than that for efficiency. Besides if you use a 430watter and by some chance it powers your system a few things may occur

1) you'll be back on here saying "hey my rig randomly reboots or BSOD's HELP"
2) you wont be able to overclock at all with any stability
3) it burns up and you cry " I got a bad PSU from XXXXXX Brand I need to RMA" when in fact its your fault it fried not XXXXXX Brands fault
4) expecting it to run at higher than rated specs causes the fault protections within the psu to fail and it fries your whole rig at which point you again cry "my psu fried and took out my mobo cpu gpu memory its XXXXXX Brands fault which again it is not


Josh while it is an older cpu and newer gen card with less power req's it is an older cpu based on older more power hungry req's than current ones.


last word the manu's make power req's because they test the cards on various platforms and find the best min req for their products. So folks dont have issues with their products and cry about it not working when they try something lower and it fails.


WooZ I'd strongly recommend at least a 550watter if not 650 for future upgrades and strongly recommend the Corsair brand.

Cx600 for when you upgrade

I looked up his CPU - it only takes 65w
But no, i fully understand what you say; it's always better to take the safe route

LMFAO you realize don't you (no I guess you don't) that's not the power draw mate that's the TDP Thermal design point TDP, which means that it can dissipate up to 65 watts of heat without exceeding the maximum junction temperature for the computer chip.


in a nutshell they put the 65watts or TDP so you know when you buy an aftermarket cooler thats rated at 50watts it aint gonna cool ur cpu while if you buy one at 125watts it will cool it

Educated, I have been!
Thankyou

np and sorry if that sounded smartassish wasnt intended to be

I think 500W will be max for this system because now i am using this cpu overclocked to 3.6 GHz and GTX 560ti overclocked to 970 MHz and that's all powered by Corsair GS600.
Because 7770 is lower end then 560ti and gpu or cpu will not be overclocked 500W are absolute max and no need for future upgrade.
And 7770 even can make use of 500W?

 

[Pr3d4t0r]

get cx500

im having x4 phenom at 3.7 and gtx460 at 12% without any issues, have it for over 2 years and still works like a charm

 

[WooZ]

Ok I will take CX500.
If cpu will bottleneck gpu then with 500W are safe to overclock?

 

[S_I_N]

if you plan to even think about overclocking I'd get a little more power say at min the cx600
