can any one tell me which of the following PSU will suit my need?
1> Zebronics delta 520w 24A on 12v
2> Gigabyte superb 460w 14A+15A on 12v
3> Cooler Master extreme power plus 460W 18A+18A on 12V
4> Corsair CX430 28A on 12v
The system is as follows:
AMD Athlon II X4 640 3GHz (hoping to unlock L3 by choosing a deneb core)
2X2GB Corsair XMS3 1333 MHz
MSI/Sapphire Radeon HD 5750 1GB DDR5
80GB Seagate SATAI
1TB WD Caviar Blue SATAII
LG SATA DVD writer
Avermedia PCI AverTV 009/709
I would choose #4 Corsair plenty for the 5750. However if you will be upgrading later on, and/or overclocking your CPU, I would consider getting something 520W or better, from Antec, Corsair, XFX or any good brand for $10-20 more. That would run any decent graphic card.
Yes, I know-as cronos177 said- that corsair is plenty for 5750. But my budget is tight. So I want to avoid overkill, especially when I won't add more devices to the system. Antec is not available here. As for 5750, it would draw 89W max TDP/ 12V = 7.42 A. CPU 130W max(no overclock)/12V = 10.83 A. So 18.25 A plus others. Won't 24A be OK? I know that cheaper PSUs wear off more quickly and slowly fail to provide required power, but I will have sufficient money in the next 2years to buy a better PSU. What do you say??
Honestly, it is a tough one, since I can't find anything on Zebronics, and I am not really sure how the 2 Rails on options #3 and 4 will distribute for CPU/GPU and other components. Sorry, but to be sure, I would still have to suggest the Corsair.
But, as I would argue, 5750 is the first in 5000 series to require a PCI-e power connector. 5670 draws 64W max from mobo. I have a 4670 that has 59W max TDP, draws from a 450W 17A. Zebronics is a renowned Indian brand. They must have tried their PSU on a gfx card. What would that be, below 5750?? Don't misunderstand me, but it's my logic.
Although I bought Gigabyte, I now know CX430 should have been the ideal choice since
i) That Gigabyte is a 400W PSU
ii) Moreover it is a dual rail with a beefy 15A on CPU rail but only a 14A on GPU
iii) CX430 can deliver much more than 430W steadily and its V2 is an 80plus
