New PSU for HD 4850

Last response: in Components
Share

Hi,

My graphics card broke recently and I bought a new one, XFX Radeon HD 4850 (XFX's page (serial HD-485X-YNFC), requirements). They recommend a 450W PSU and I only have a 430W one. I thought it'd be enough but I was wrong. The computer shuts down every now and then during games, apparently during power drain peaks.

My current PSU is Antec's NEO HE 430W (specs) and it should be a pretty good PSU. However, it's 3 years old now, I think, so the performance may have gone down.

I'm looking for a new PSU but I'm trying to keep the costs down. After all, I only got a new GFX card because my old one broke and now I'm a little bugged that I even have to get a new PSU. Anyway, my setup looks like this:

ASRock ConRoeXFire-eSATA2
Intel E6300 + fan
2 x 1GB DDR2, 667MHz
Radeon HD 4850
DVD drive
Disk drive
1 x SATA HDD
1 x 120mm rear fan

However, I might do the following in the future:

-Overclock the CPU to improve the performance a little, nothing extreme
-Get a sound card
-Get an SSD HD (in the distant future)
-Get more memory

Do you think Antec's Basiq 500W (specs) would meet the current requirements of my system? What about the future requirements (with OC, SSD...)?

Recommendations are welcome, though their availability in my geographical area might be limited. I can't really give you a price range either because here we pay with rat pelts, and things generally cost a bit more than in, say, the US.

I'm surprised to hear you have problems, I have a 4850 too. I use a generic 450W PSU, my CPU is overcloked and I've never had any problems with my PC... I doubt 20W would make any difference.

I would have thought you would be ok too since that Antec unit is a pretty decent PSU however as you mentioned it may less effective due to its age.

The Corsair 550VX would suit your needs very well if you can afford it and obtain it in your area. Although saying that the Antec NEO ECO 520W is on sale on Newegg at the moment - I know its an American site but its a steal at its price so if you can get hold of that it would also be a good choice. Hope this helps!

If budget is a concern then you can go as low as OCZ Modxstream 500W PSU. It will handle the rig just fine.

But I would recommend you a Corsair 450VX which is an awesome 450W PSU with 5 year warranty and it will handle quite a number of cards :) 

Thanks for the suggestions and help.

I checked the prices of the PSUs you mentioned and here's what I found (with currency converted):

Antec Earthwatts 550W - $100
Antec Earthwatts 650W - $100 :heink: 
Antec NEO ECO 520W - couldn't find
Corsair 450VX - $92
Corsair 550VX - $102
Corsair 550TX - couldn't find
OCZ ModXStream 500W - $92

A tad bit expensive, the Antec Basiqs I've been looking at are:

Antec Basiq 500W - $64
Antec Basiq 550W - $83

I think I might go with one of those unless someone has any objections. By the way, which one would you pick at those prices?

The best bet would be an Antec Earthwatts 650W which is a very good unit. It can even handle 2 4850 is CF!!

It will be good for your future builds also.

The second one I Choose is Corsair 550VX.

The Antec Basiq models are ok but as the name suggests they are the basic, entry level PSU from Antec. They don't have the build quality or durability of their newer models (those which were manufactured by Seasonic). That's not to say they are bad PSUs just that they aren't quite to the standard of their mid-high end models. You can by all means go for one of these if thats what your budget allows, although the Corsair 550VX would just give you that little bit more. It depends on what your budget allows. Hope this helps :)

You have some very good PSUs there.

Anyway, given the price, I recommend you to go for the ANTEC EarthWatts 650W. It has an excellent price/performance ratio.
This PSU has been made by Delta Electronics which is one of the best PSU manufacturers nowadays.
It has a good ripple and noise suppression and a high efficiency (80Plus certified) that keeps itself cool and because of that it runs very quiet. The fan is an ADDA AD1212HB-A7BGL (high-speed and low noise ball bearing fan) of 12cm in diameter and 2,5cm high with seven blades and 85,2 CFM at 12 V (0,37A).
It has plenty of connectors (6x Molex Power Connectors, 6x Serial ATA Power Connectors,...)
The voltage regulation on the +12V is very good providing 540W on the three 12V rails (2x22A+1x25A). It has 1x6PCIe and 1x(6+2)PCIe connectors. Both PCI-E connectors are joined to take the 12V3 (25A) all to themselves.
The protection circuitry prevents damage resulting from short circuits, power overloads, over voltage, and under voltage.

I also have running an Antec NeoHE 430W (by Seasonic) in one of my computers, so We both know about the high quality of the Antec PSUs. The EarthWatts 650W is not an exception. I highly recommend it.

Alright, I think I'm gonna get a bit better one then. Either EarthWatts 650W or Corsair 550VX, I'll have to sleep on it. Thanks for the help!

Edit: and the lesser EarthWatts was apparently 500W, not 550W like I said earlier
