Corsair Power Supply Configurator

Seems to be doing fine. I first time posted with 4GB, then added the other 4. Came up like a dream.
The 8GB is for Photoshop CS3 and such. Running tests right now. Because.....

Cannot get the system to overclock. Not likely the RAM's fault, and just want to see if it will do it, then put it back. But gotta test all the hardware to see.

Not one OS error. Not one program install problem. Runs really well. Opens and processes 12MB RAW image files effortlessly.

Have a look, (delete the dash in the link) the fan shroud is close but...... http:-//users.adelphia.net/~allen22/quadcore.JPG

You'll need to increase your MCH voltage most likely with 4 DIMMs to get an OC. 4 modules and a quad are a heavy load to OC.

The Configurator might need a little tweaking.

I set it up with a 2 hard drive system and got the 550 as a result. I then put in the same specs changing the 2 HDs to 4 HDs and it came back suggesting a 1000 PSU. I don't think adding 2 more hard drives should do that. It should have suggested the 650 or 750.

Thanks Guys, All tests came back OK, Stable.

It was a legacy thing. When rebooting to a new BIOS (clocking) it sometimes fails and reboots to defaults due to devices attached to the PC. In my case a WD MyBook 500GB USB. I unplugged it and she will hold a clock now. I shut down, reattached the MyBook and all is well.

We are rockin in the free world now.

I'm very happy with my HX620W which I bought about 1 year ago. It's more than I need for my current rig, but I leaves room for expansion. I'm pretty much impressed with quality of the unit. Go Corsair!

I'd like to see a calc that's based on Amperage, since Wattage is basically a useless metric, and it'd be nice to be able to find a rough estimate of the Amperage common components pull without having to search all over the web.

This calc is nice and simply, which I guess is a plus for some people, but seems to always suggest the 520W and 550W no matter what I put in here, even though I can barely run my system on your 650. (Granted I do have a few PCI/Ex cards.)

What is in your system that a 650 can barely run???

I recently ran a MONSTER system with our HX-620 and while it did get warm it never flinched. Were you pulling more power than this:

EVGA 780i
QX9770 at 4.1gbz
4 x 2gb PC6400C4 DHX
EVGA 9800GX2 w/Danger Den block
2 X 74gb Raptors
1 Optical Drive
2 x Nautilus 500s, CPU and GPU
Gigabyte I-RAM
3 Fans laying on the MOBO

IP35 Pro
Q6600 @ 3GHz
4 x 1GB sticks
5 HDs
SATA DVD burner
Asus Xonar DX2
8800GTX
Intel dual port gig server NIC
Hauppage PVR-500
A bunch of USB stuff (360 controller, iPod dock, Wireless mouse receiver, uplink to hub on my monitor) - although this shouldn't be pulling that much.

If you are having problems with that setup and the 650, then the psu is defective and should be rma'ed. You have plenty of headroom amperage wise.

By my calcs, the drives and GTX alone are pulling something like ~40A out of a total of "+12V@52A." Not sure how much everything else is pulling though, as it's hard to find power ratings in Amperage most times...

With all due respect, I think your calculations must have a fundamental problem. I can't think of a hd that I've ever seen that is spec'd for more than a fraction of an amp off of the 12 volt supply, plus modest additional current from the 5V supply (aside possibly from transient peaks which would not occur simultaneously on all of the drives). I checked the specs for this 8800GTX card: BFG Tech - BFG NVIDIA GeForce 8800 GTX OC 768MB PCIe, which indicate the following under minimum system requirements:

A 475W PCI Express-compliant system power supply with a combined 12V current rating of 32A or more *Minimum system power requirement based on a standard PC configured with an Intel® Core™2 Extreme X6800 processor 30A

That does not say that the card's 12V requirement is 32A; it says that the supply should be able to provide 32A @ 12V for the entire system. So I think that 40A from the 12V supply for the drives and the graphics card is way over-estimated.

Edit: It looks like my drives actually pull about .5-.6A. We figure SATA drives at 2A in our data center, which is what I was going by...

I wasn't certain about the video card, but I KNOW that this PSU will not run all of my components properly. I guess I will try to RMA it.

Also note that a lot of those compenents will not be running at once.

Are you daisy chaining a lot of those components? Or do you have a lot of pigtails coming out of the power supply. Those wires are not very heavy and once you start pulling a lot of amps through them, you will start seeing voltage drops.

[Joe Public]

An 8800GTX would probably need 11-12A worst case. The TX650 should be laughing at that setup, so it's either a defective PSU or something else. But lack of power it is not.
