I am running an Asus M2N68-AM PLUS motherboard, AMD Athalon II X3 445 Rana 3.1GHz, Corsair XMS2 4GB DDR2 800MHz (2X2Gb kit), 2 Samsung CD/DVD Sata Burners, 1 WD Caviar Blue 160GB Sata drive, 1 WD Caviar Blue 320GB Sata drive, 1 Nvidia Geforce 8800GT PCIe 2.0 x16 Graphics card, 1 PCI TV tuner card, USB keyboard & mouse, 3 120mm case fans, 1 90mm case fan and 1 multi-card reader. I have used a power supply calculator and found my system to Recommend at least a 700W power supply. I am looking to buy either a 850 or 900 watt supply to run this system. Does anybody have any suggested brands I should be looking at?

Thanks,
Brett

Well, first of all, your conclusion is hilarious..
Athlon II X3 ~ 90W
8800GT ~ 130W
everything else ~ 50W

What exactly are you planing on doing with a 900W power supply, considering you'll keep it around 15% load most of the time!?..
Anything above 450W is a poor choice for this system..
 
Also, I am building a new system for home/internet use. It will have an MSI 760GM-P35 AM3 Motherboard, AMD Phenom II X6 1090T BE 3.2GHz processor, Kingston HyperX Blu 4GB (2x2GB kit) DDR3 1333MHz, Kingston HyperX Blu 8GB (2x4GB kit) DDR3 1333MHz, OCZ Agility 2 60GB SATA II SSD, Corsair Nova Sries 2 60GB SATA II SSD, WD Caviar Green 1.5TB HDD, Samsung CD/DVD SATA Burner, Nvidia Geforce GTS 250 or GTS 450 PCIe Graphics card, 4 120mm case fans, USB keyboard, Logitec gaming mouse and Logitec game pad. Once again I have used a power supply calculator (ASUS's website) and found that this system will either require a 600W if the GTS250 is used and a 500W if the GTS450 is used. Any thoughts on power supply brands for this system?

Thanks,
Brett
 
Thanks for the Info. :)

What good is a power supply calculator if the results are way off???
 
You're cracking me up.. honestly, don't you think that something might be wrong with that PSU calculator if it suggests a lower power draw for a hexacore Thuban than a tripplecore Rana considering that both the GTS 250 and the GTS 450 are low ends with pretty modest power needs?

1'st, every single online PSU calculator out there is utter shit, looking for info in such places is like getting brain surgery at the barbershop ;)

In regards to the power needs of this system, a solid 450W unit will suffice, but may I ask, why two different SSD!?

Because they have their fundamentals wrong, and because they need to account for every trash PSU out there that can't provide half its labeled power, like this Coolmax V-500 that can't output more than ~220W 12v power ;)

As for suggestions, if you're buying from newegg, go with the XFX Core 450W which is an excellent unit for the money.. if you're in Europe, link the shops you intend to buy from and you'll get the best suggestions that way ;)

I have had this same system on a 600W supply for two years now and it shot craps on me, like I burned up the supply or something. It was a Cooler Master Silent Pro M600 600W ATX Power Supply @ 80 Plus Bronze Certified. You say that it should run on a 450w, what could have cause my $120 power supply to fail a month after the two year mark?

Two different SSDs because I am sort of on a budget is all. if i wasn't, then i would go with two Corsair 128GB SSDs one for OS and other for Programs. (128GB size just to be on the safe side)

I am in the US and I do the majority of buying from Newegg. That said, how would I be able to tell which PSUs are good and which ones are bad. I read the reviews and talk to my tech buddies at work. Should I just stick with Antec because I know that they are good?
 
A good thing to do when in doubt is buy a Corsair TX650. Plenty of power for any single card application, usually always on sale somewhere for $70 to $80, superbly built and in your case will have good headroom for future overclocmed and upgrades

Not saying it should run on a 450W unit, i'm saying it will run on a 300W unit ;)
What exactly caused your PSU's death is impossible to tell until you open it up and see what exactly failed, maybe do some close up and upload them so we can have a look.. what surely didn't cause your PSU to fail is excessive power draw, that particular unit has OCP(over current protection) which shuts down the PSU to protect it when the load exceeds its limits;).. either way, that PSU most likely never saw 50% load :)

There are many good PSUs selling under different brands and made by many different OEMs, have a look here for a large selection of excellent to decent PSUs.

There are more than a few things wrong with this approach, which i'm not gonna point out now as this is not the place for SSD discussions, but make an effort and get a larger one or simply buy two identical ones and do a RAID matrix.

Even Antec has a few bad or low quality or slightly defective PSUs in their lineup. This PSU review list is a tad outdated but should tell you which sites you should check for PSU reviews:

RE: becand75

Which one of those suggested above would be optimal for my system (signature) when I add a HD6770 or DH6870? I haven't decided on a GPU yet, it's a $60 difference.

I was looking at the Coolmax CU-600B until I read this thread.
 
corsair tx650 gets my vote for your system, tx750 if you ever plan to go crossfire. They are a great PSU with minimal ripple, even at its limits. For the price...a high quality PSU. The XFX core edition is just about the same inside. Both use a Seasonic design.

You could easily run that off a good 400-500W PSU. Here are some good options to consider:

Not all Coolmax power supplies are junk.
