Cheap and good PSU for Sapphire HD 4850.

Hello,

My name is Srikanth from india. Today I brought used Sapphire HD 4850 1Gb for 76$ from ebay.com. Which I may get soon in hand.

After reading plenty( Most of from this greatest site ) info and research I choiced this card. Its cheaper and great.

But I have some doubts about getting a new/used/etc PSU. At present I have 450w Intex and I'm sure it won't suit as it has only 20A on +12v rail and is a single rail PSU but card needs 30A atleast.

So I searched for PSU but socked, they are nearly costing to graphics card ( 50$ ) and I cannot pay that much. I had also searched most of computer dealers in my city and they didn't have stock and they said, we can bring for you but costs nearly 100$. pff :sweat: 

I found some cheap PSU on some websites. They are above 600w and 35A above on single +12v rail.

http://www.amazon.com/dp/B001M5DSMO/ref=asc_df_B001M5DS...

http://www.amazon.com/Blue-Star-4-pin-Supply-PCI-Expres...

I know using uses isn't good but what to do, I don't have money to get a good branded. Just I can spend 30$ max including shipping.

Could anybody tell me if these are ( above said PSUs ) are ok to use or atleast please help me to get a cheaper one.

BTW; I don't have plan on crossfire or my motherboard supports. Below is my PC Config.... :

AMD Athlon II X2 240 @ 2.8GHz of 65w
ASUS M2N68-AM Plus
2+1 GB DDR2 RAM ( I think 650mhz both cards )
320GB Samsung Sata HDD
Sony DVD/CD re/writer

p.s also let me know if 4850 card is suitable for my pc or I brought it without enough knowledge. :cry: 

Thanks a lot...
Best Regards

A 4850 would be a great match for your system. As for the PSU that is very hard. They may work, they may not. I can't think of a PSU that I'd wholeheartedly recommend in the $15 range.

Glad to hear I brought a matching graphics card to my PC but as of PSU I'm stressed. Researching since 2 - 3 days and now I'm unable to work and lil headache. Wish I have some more bucks. :pfff: 

Thanks for your reply.

Edit: I found a another psu of 500w but as of its amperes its suitable ( 380w / 12v = 31.6a ).

Not sure about its price yet but I think its nice brand.

Edit2: damn, its costly. :(

I know this is like double your budget, but I'd never recommend a no name/generic power supply, its very important to get a quality power supply.

This one has 420W on the +12V rails or 35A which will be enough for your system.


Thanks but thats hard to buy for me.

I got this http://cgi.ebay.com/RECOM-RC-PROE-A600-600W-POWER-SUPPL... just now and as per its spec +12v1 has 22a and +12v2 has 22a. But I couldn't find wattage of both +12 rails. Still searching though.

He/She says it has 500W over the +12V rails. So the max amperage the +12V rails could provide is 41.6A
I haven't heard of the brand and I wouldn't buy a second hand power supply.

Hope it works out for you.

Oops, I didn't read that he did wrote 500w over +12v rails. as most sellers don't write wattage of +12v rails or they just post snap of psu. But I think he/she wrote wrong. here its written 438w Combined power of +12v which means 438/12=36.5a Great!

Howevery, I think this card is better then others cheaper single rail psu on amazon.

Yeah of course, as its a netherlands company usa ppl won't be knowing that. :) 

Wish wish I won this.... 2:20 hours left and no bidders. Hope I won this.

BTW; I think you have misread. Its new product and not used as said but may be good as said. :D 

Thanks....

Glad you got it. That should have enough overhead so even if the specs are exaggerated, it should work.

Yeah one of a member named "abondanzieri" is using same products I brought. And I don't think he has any of issue except one that your posted :kaola:  :

http://www.tomshardware.com/forum/253651-33-4850-crysis

But as far as crysis, its a heavy game or I don't play it. I have interest in Need For Speed Shift, COD MW2, Assassin Creed 2, GTA4 ( I know it won't run so good but lot better then my inbuilt GPU ;)  ) and may be some more latest games which I couldn't remember atm.

However I have sent a PM to abondanzieri to ask his experience with these products.

Best Regards

It should run pretty well on those games. I have 4850s in my secondary PCs and it worked great in Assassin's Creed I, and from what I have heard, AC2 should not be much more demanding.

Still not solved guys. The psu what I won got costly. Not about product price but its shipping cost. Seller said 55$ for shipping to india. pff

I checked usps and First-Class Mail International Package which was 17$ but the seller wasn't not ready to go cheaper. May be he used to get som $$$ from shipping cost we pay. :( 

Still looking...

As of Graphics Card, good news. Seller has contacted to usps and he said 35$ including coverage for shipping. Its cheaper then I though ( 50$ ). :) 

Best Regards

Edit: If anybody has used psu of 450w or above with atleast 30a on +12v rail/s. Please let me know. I'm ready to pay 30 to 35$ but not over...
March 27, 2010 1:17:53 AM

Hello, I'm also purchasing a 4850, would anybody be able to post a PSU able to power one in the 30~60$ price range (the cheaper the better) that's available on Newegg? Thank you.

Hey guys,

Guess what?

First good news, I have received my graphic card card today and the card is soooooo wonderful. Purchased it as used graphic card but I got a like brand new card. Seal is opened but there are no signs of use. Not even a single.

Second good news, I used 2nd psu for graphic card itself of rating 20a on 12+ rails ( 400w psu ).

Third good news, The graphic card temperature isn't gone above 56*c on full load and 42*c on idle. Now trying NFS SHIFT and I'm sure it never goes above 60*c !


Bad news is, customs duty charged 45$ approx and that was way too much for 100$ item and there was no other ways. Either give 45$ and get the parcel or leave it as it returns back to the seller.

So thats all...

And I'm v.v.v.v.v happy. :bounce: 

Was too much worried about graphic card heating issue and psu but both solved very easily.

Thanks a lot...
Best Regards

Well, I'm glad it is working out well for you. Sure would have been depressing if it hadn't after all the work you had to do to get the parts. Enjoy your new GPU/PSU!

Now playing nfs shift and its so realistic. Its just like I'm racing car in my street..... :o 

But I cannot understand why most of ppl reported this card has heating issue. Mine never touched 57*c on full load ( while playing nfs shift ). I'm living in high heat area of 35*c today.

I haven't installed any 3rd party coolers into the gpu and nothing noticeable customizations to the cabinet. Just used a single cabinet fan and the cabinet is full tower of course.
April 16, 2010 1:11:31 PM

The original 4850s were very hot (I had one) but they quickly adjusted BIOSes and put (much) better coolers on at the factory and the issue was completely resolved. Is your 4850 a 'dual slot' card (in other words the GPU cooler blocks the PCI slot below it)?

Yeah its a dual slot type card but uses only single pci slot. SAPPHIRE HD 4850 1GB GDDR3 PCI-E HDMI.
April 16, 2010 8:22:11 PM

Yep, that is the type that fixed the heat issue.

ok thats great.

BTW; I have a few lil Queries.

As the graphic card power consumption is more, on my normal works ( other then gaming and 3d softwares ) what is the easy way to turn off the graphic card pluse 2nd psu and use inbuilt video? Or I can use the graphic card all the time as it doesn't harm anything?

1. Connect the VGA cable into mother board VGA port ( Inbuilt video ) and turn off 2nd psu?
2. do as above plus remove the graphic card from the mother board pcie slot?
3. Or is there any other easier ways?

FYI; I use my pc for atleast 20 hours daily.

Thanks....

The cards are designed to run for a long time (many around here sound like they do 24/7) and therefore have power saving features. I don't know exactly what yours does (they got better with later revisions/bioses) but it should downclock and undervolt when not in 3D which can save a huge amount of power (and it will run cooler). If you want to use the onboard, you'd have to physically remove the 4850, and it would likely make a mess of the drivers (not really made to switch back and forth) so I would not recommend it.

Yeah you are right and my card has power saving feature!

On idle or 2d, the GPU core clock goes to 160 Mhz and GPU memory clock goes to 250 Mhz. Temp below 40*c. No idea about volts as its not shown in GPU-Z.
April 18, 2010 10:13:40 PM

Wow, so they really did improve it. My 4850 would only go down to 500/750. At those speeds (and assuming equally low volts) it will not be consuming much power at all. So definitely don't worry about it.

Yeah glad to hear it. :) 

BTW; the bios version and date seems bit old. Version : 011.014.000.03. Date : 2009/01/07 Cannot understand its 01 July 2009 or 07 January 2009




Does it require any updates or its ok to go with this?

Sorry for going out of topic. But this is last query. ;) 

April 19, 2010 12:13:50 PM

Well, the ones that ran very hot were made in summer of 2008, so either way you have a fairly new BIOS. So no, no need to update. And updating a card BIOS is no simple task like for a motherboard.
