Reccomendations on 600-700W PSU?

post #1 of 9
Thread Starter 
I am looking for recommendations on a new PSU. I honestly had an Antec Earthwatts 380W that was able to power my microATX system but right after I upgraded to a midATX motherboard and a new larger case my power supply was not sufficient enough and it did provide enough juice to power my rig nor did it have the juice to turn on the LED power indicator on my case. I am possibly looking to upgrade to a decent 600-700W power supply that has a price that is affordable and not break my bank, maybe somewhere around $50-$75. If anyone is wondering, my current rig spec's are listed in my sig and maybe I might purchase another 4850 to crossfire in the near future.

Here are what I have in mind thus far:

Antec Earthwatts EA650 650W

Antec NEO ECO 620C 620W


Thanks,
VAMBA

You wouldn't need that much power but it'll offer more headroom for future upgrades and for OC'ing.
Both PSUs you mentioned are pretty good.

This is a great PSU. Will definitely be enough for you to crossfire. A solid 500W PSU would do this for you, such as this, if you're not planning on doing much other than adding another GPU.

Edit: The first PSU you mentioned is also a great candidate. It's a bit cheaper than the TX650 and will probably perform just about as well. If you like the looks of it, definitely save the $15 and go for that. Didn't see the price on the thing before. tongue.gif

Your system definitely uses under 300W full load.

Antec Earthwatts xxxD weren't released that long ago, less than 3 years I think, so yours can't be older than that. So if the power supply really is to blame, it's probably under warranty.

What did you upgrade other than the motherboard and case, such that it used to work and now it doesn't? You tried booting with a less powerful GPU or something like that and it worked? What I'm trying to say is...you've confirmed it's the power supply at fault?

Unless your EA-380D is faulty, it can easily power that system with a single 4850...

Although I don't advise getting a 600w PSU as well, you can never go wrong with the Corsair HX650w. While it does cost almost as much as 750w power supplies, its modular and is one of the most high quality PSU's out there.

EDIT: I looked at the PSU's you listed and infer that you don't have a $130 budget on a PSU. I'd go with the Earthwatt

Those PSU's you listed are both great, i have a antec neo eco 620c its small quiet and gives quality power... But i got it for 45$ you should go for the earthwatts.

Yes. I tried replacing both my motherboard and my cpu and it would not power. So then after more troubleshooting I finally decided it may be my power supply. What happened was that I tried switching my Earthwatts 380D with a cheapo-brand 430W power supply with only the video card, cpu and hard drive attached and it powered without any problems. It may be the fact that my Earthwatts 380D may have had trouble powering the 3 120mm and 2 140mm fans that are in my Lancool case as well since my previous case had only 3 120mm fans but I am not certain.




I appreciate the responses guys. I might pull the trigger on an Earthwatts EA650 soon.

Those fans probably take no more than 4W each at top speeds, so I doubt that's a deciding factor. Most likely, a working Earthwatts 380D can put out more power than a cheapo brand 430W anyway.

Have you seen the Earthwatts power on anything since you've had issues? The power supply fan turns on but nothing else does? What happens when you do the power on test via shorting black/green on the 24-pin motherboard connector?

Anyway, if it's not working and you're buying a replacement, you may as well RMA it so you can get a quality backup unit or something to sell.
