ATI HD 4850 PSU Requirement

[smartali89]

how much psu power is required for hd4850 ? Will it work with 300W??

 

[dark2099]

I highly doubt it, most companies are listing that it needs 450W minimum.

 

[smartali89]

I am going to have some upgrades on my pc like I will change my processor to Intel E8400, Corsiar 4gb Dominator and HD 4850

I currently have 300W PSU

 

[wolf2009]

it may work, but forget overclocking. on stock too it may not work .

 

[smartali89]

so how much will I need?

 

[dark2099]

Before you get any of that I would suggest getting a new PSU since your current one is probably being pushed to its max.

Get atleast a 450w FROM A GOOD BRAND. Most people buy bad brands!

 

[smartali89]

CoolerMaster?? 460W Or 500W???

 

[ShadowFold]

I would not recommend cooler master.. Look for Enermax, Corsair, Antec(earthwatts, True Power), Mushkin, FSP, OCZ.

If its all you can find where you live then its ok tho!

 

[dark2099]

Don't forget Silverstone.

 

[smartali89]

Corsair is available but not in my budget

 

[ShadowFold]

even the 450w? BTW A good brand like Silverstone, Antec Earthwatts, Enermax, Silverstone 350w would be good too!

 

[proletariandan]

Antec is also a good brand that is relatively affordable. I have an Athlon X2 & Radeon 3850 that only use about 160W at load, so you don't always have to follow the manufacturer recommendations but it isn't a bad idea, especially if you plan to overclock which can drastically raise power consumption.

 

[smartali89]

Here only Corsair, CoolMaster and Real Power Pro is available

COrsair and Real Power Pro have 600W+ PSU

only CoolMaster has 450W available

 

[proletariandan]

450w will be more than enough if you aren't going to do crossfire or anything crazy like that.

 

[smartali89]

I wont crossfire but will oc

Highest power consumption is 309W for a dual-GPU with an overclocked CPU. I'm sure you'll be fine with 450W.

 

[smartali89]

That means I can stay with 300W If I dont OC...

 

[proletariandan]

Most likely, but I would recommend a device that I also use called a Kill-a-watt (or something similar) that you can use to measure your power consumption. If you are constantly using 250W of a low-quality 300W PSU then its not going to last long. What brand is the 300W?

No your 300w is a crap brand. I would never trust a high wattage card with a crap brand.

Forgot to check your specs; I agree - get the 450W to protect your system. If your crappy PSU goes it could take anything or everything with it.

The power supply is the most crucial part of the system. One hiccup and your system is done. I will never understand why people will cheap out on this part.

Do yourself a favour and get a new, quality power supply. It might seem like a big investment buying a PSU for $80+ when you can get one with the same wattage for < $50 (for crappier brands) but, it's worth it for the peace of mind. Also, you're probably going to continue to use it in the future if you upgrade to newer next generation parts and not just throw it away.

I got my Antec Earthwatts 500w for 50$ on newegg cause it was on sale
