Is a 450W Power Supply enough for HD 4670?

[Achilleas]

I am about on the way to purchase a radeon HD 4670 from Sapphire as well as a phenomII x3 710, however I don't be familiar with if my power supply will transport the power I require as well as I don't be familiar with if my mobo will get burned up! These are my current system specifications:
amd athlon x2 5000+ 2.6 ghz 450w cpu
4gb ddr2 800
250gb at 7200rpm sata (WD)
Asus m3a78-emh-hdmi using on-board graphics ''radeon hd 3200"
I've acquired a 300w power supply that come bundled by means of the case these are the essential specifications: 2 12V rails, the first one is at 10A and the second one delivers up to 14A .I have read somewhere that the 4670 require a 400W by means of 18A 12V rails, as well as I don't be familiar with if my power supply will hold a 95w CPU as well as a HD4670 with no burning my system up. Need help. Any suggestion would be appreciated.

As per my experience for running HD 4670, Corsair VX450 may possibly be overkill. I would suggest you to allow us be familiar with your budget. On the other hand you have on the way to spend at least 1.5k for getting a good power supply. Obtain a Gigabyte LC400 80+ 400W at 1.6k. It will be adequate on the way to run HD 4670. If you desire a little additional power at that moment obtain VIP Gold 600W at 2.8k or else Gigabyte 80 Plus Active PFC 460W at 2.2k.

The most important thing regarding a power supply is Amp over the +12V rail. Not wattage you will not run the Graphic on its own. You require power designed for the CPU, HD, RAM etc.Obtain a proper power supply. A cheap power supply is able on the way to destroy your computer.HD4650 is an underclocked HD4670. As well as memory bandwidth is half that of HD4670.

VIP is fine only in efficiency. However FSP/Gigabyte is far superior as compare to it. Add to it, FSP as well as Gigabyte is PFC active, possibly VIP is not. As well I doubt VIP have any security.It’s similar to spend less today, cry tomorrow. Or else spend a bit more and smile tomorrow.Yes you are correct other than what when your power supply goes up at the same time as gaming and you end up burning your graphics card as well as processor.

Provided that your generic power supply has the necessary PCI-E power connector after that I do not distinguish why it would be a problem. On the other hand if it does not, after that the permanent solution would be on the way to replace your power supply, except of course you wish on the way to do it a cheaper way as well as obtain an adapter which be able to be used by means of your current power supply.I appreciate the minimum suggested power supply is listed as 400W other than it is just that a suggestion. You need 550W power supply however only if you intend on the way to utilize two cards in Crossfire. As a result in my opinion I believe you should be ok particularly at what time your other listed components are taken into thought.

As per my knowledge Radeon HD4670 Ultimate make use of 131W on idle as well as 189W on full load. Your 450W power supply is supposed to cope without any trouble. I believe your major worry should be the case cooling in view of the fact that HD4670 Ultimate is an inactively cooled card there is no fan on the heatsink. It does lean on the way to make quite a bit of heat as well, as a result except your case has a sufficient cooling it may possibly become a trouble.
