Does HD 7750 require less power than HD 6670?

[harshilsharma63]

will my Intex 500 w psu is enough ? I dont want to invest anything on psu for now.
7750 or 7770 ? confusion.

It's not just about Wattage, its about consistent power delivery which these local PSU's fail at. You should invest in a better PSU to avoid damage to your PC.

HD 7770 is about 10-15% percent faster than a HD 7750? Correct me If'm wrong.
But you'll definitely need to change your PSU if you are getting HD 7770. But for HD 7750 even a local PSU can handle it but it's much better to use it with a better PSU(Like Corsair, Antec, Seasonic etc.)

performance difference is around ~20%

Does anyone know if I can run a HD7770 or a HD7790 on my Corsair CX430 PSU?
My Config is an AMD A10 5800K Proccy
2 WD Blue 500GB HDDs
3 Case Fans (LED) and 2X4GB DDR3 CORSAIR VENGEANCE RAM Modules

BUT I have the CMPSU-430CXV2 Model of CX 430, not the latest one. The difference being that the one I have's Max. Load @+12V is 336W NOT 384W like the latest one.

which brand and model? saying 500w is just not enough. If it's local brand , get hd 7770 at 8k and antec vp450p at 2.6k.

Corsair VS450 450 Watt PSU - Corsair: Flipkart.com

it can be available cheaper locally as flipkart is overpriced for most pc components. hd7770 and antec vp450p is best and it is approximately 20% faster than 7750. BTW, what is the pc configuration such as cpu, ram etc? nvidia cant compete with amd at this price range.
dont go for vs series from corsair. get the antec one

He is not ready to invest in psu...
cpu = Intel Core2 Duo E6550 @ 2.33GHz
ram = ddr2 2 gb 800 mhz

I guess 7750 for his local psu will be best, what say ?? 7770 might kill his psu and bottleneck the cpu also ??

Also for myself I am thinking of this... my configuration is in sigi

7770 is then just an overkill for the cpu.get hd 7750 at around 6.8k. why cant the remaining money spend on a good quality psu? get 2gb ram if possible. even if the current psu may handle the gpu ,but have a read here *www.thinkdigit.com/forum/power-supply-cabinets-mods/104472-basic-guide-right-power-supply.html

your q8300 can handle hd 7770 easily and that will produce good improvement over hd 7750. just make sure to get a new psu

my budget is not 10k.. that's why i am sticking to 7750.. I hope my Intex 500 w psu will handle it. it's handling my GT 9400 since last 4 years..

 

[topgear]

what's the +12v rail rating of the intex psu ?

 

[rijinpk1]

no problem. then get hd 7750 and not to forget....pray

 

[RohanM]

what's the +12v rail rating of the intex psu ?

Need to check that. Will upload a pic soon.

 

[RohanM]

^That comes about 25A (+12V Rail & -12V Rail: AMP. ratings together)which is dangerous if you have a Graphics card installed.
It's a crappy PSU,mate change NOW immediately,else you will repent...

General RULE OF THE THUMB...the more current AMP rating your single(or dual or multiple) 12V rail of the PSU has,it's more stable & robust & caring & COSTLY also.
Of course look out for the specs. in details and search the net for other users reviews,also be warned not to have false ratings on the PSU label from unknown manufacturers.

I am using Nvidia GT 9400 since 2008... with this psu.. + 2 WD HDD + One extra fan at back - 120 MM ... rest of config is in sigi...
Do u seriously saying to change the psu ?
Also suggest some psu but my budget is not much around 2k...

 

[Nerevarine]

HD 7770 should be around 7.5k locally..
and a good PSU will cost 2.5k..( CX430v2)
