Here is the PSU (I know it's not the best, but will be able to afford a nicer upgrade in a couple months):

I plan to replace my AMD Athlon 64 4200 x2 and MSI K9A Platinum with a Phenom II x4 and an ASUS M4A79.

My case has the following already if it matters:
3x SATA 7200rpm HDs
2x ATI x1650Pro in Crossfire
1x Tuner Card (PCI)
1x PCI slot fan
3x 120mm case fans
1x 92mm case fan

You think the power supply is strong enough? I'll be able to upgrade in a few months like mentioned to something a lot better, but would like to to these upgrades now.

if you buy that psu, you're just asking it to blow up your components

If you must get a cheap psu, this Thermaltake is $50-25mir with free shipping if you join Neweggs email account and use code EMCMNPM56 by 1/6.

That PSU only has about 22-24A on the combined 12v rails! I wouldn't get that for a crossfire setup!

Or get a nice one OCZ for $45 after MIR and it is even modular for nicer cable management.

That PSU would definately be better than the last 2 suggestions, but it's $55 after the MIR's ($80 out the door), becasue of the $10 shipping charge!

I'd recommend PSU's from Antec, Corsair, PCP&C, and Seasonic, but right now they aren't having any REALLY good deals on them, so they are about $70 and up :(

I'd add onto that list the rosewill green series.

I wouldnt' recommend teh Rosewill Green series just yet. I've only seen 1 review and that was for the 630w version and the reviewer stated:
This power supply is manufactured by ATNG. Interesting enough internally this power supply uses the same design from another unit from Rosewill that we’ve already tested, Performance 650 W, which for some reason is not listed on Rosewill’s website. In our tests with Performance 650 W we discovered that it could not deliver its labeled power at high temperatures. It seems that Rosewill got the same power supply, put components with higher current limits on the secondary and reduced its labeled power (and stating that it can deliver 630 W at 40º C), selling it with a different name.

So I'm not sold on them yet. I'll have to have more reviews to decide if I'm buying them for my systems.

Well when price is a concern (and it often is) buying the absolute best isn't always an option. Recommending something that is at least close (when there aren't more reviews yet) is better than having people ignore you and just buying, say,
which, let's be honest here, most people end up with stuff like that. Especially when people get PSU + case combos.

Now besides all that I saw in some power supply forums where people were talking about it and the manufacturers were pretty good. I got the 530 watt for $40 when it was on sale and it's done a good job in 3 different computers.

Oh I'm not saying the Rosewill is a bad PSU, but I've had my run-ins with cheap PSU's, so I won't recommend them (Raidmax, Logisys, Apevia, etc.). The BFG is a good buy for the $ right now, so that is what I'd recommend for ~$50 :)

Use this or an equivalent to figure out what you need.

Don't forget to check all the drop downs and include capacitor aging and other items. When ya done, I like to multiply by 1.2 to 1.5 so that I am operating in the most efficient range and I haven't tripped the fan onto hi speed.

Then I take the answer and go to the Editor's Choice List here.....

....look at the list, read the on site review, then head over to for a second opinion. Then off to newegg to see if it's affortdable for the build in question....if not back to the site and drop down to the "Recommended List"....."rinse and repeat" as above.

Aye, a 500w will work 100% fine with a phenom II, unless you are planning to get some more powerful components (e.g a graphics card). I've seen the phenom II work on an antec truepower 350w before.

do you already have the Rosewill if yes then like the theneomaster said will work
but not the most reliable psu might want to replace it soon
