I've got kind of a noob question :ange:  . I'm getting a couple different answers about my PSU. I'm wanting to get a BFG GTX260 OC2. On there webite it says it requires a: 525W PCI Express®-compliant system power supply with a combined 12V current rating of 38A or more (Minimum system power requirement based on a PC configured with an Intel Core®2 Extreme QX9650 processor). I have an Antec Neopower blue 650W psu with three 12v rails at +19. If you add those you get 57 of course just curious if it works that way.

Some people say you can add all three together for total some say you can't. I just need a clarification since psu jargon is still a little new to me. Here is my system specs: Asus P5E, Q6600, 2 7,200 HDs, 8 gigs ram(ddr2 800), currently and EVGA 8600gt, and one combo drive. Any help clarifing wether I can use my PSU or not would be most helpful. Thanks

Max on that PSU is 52amps on 12v rail I believe. you should be fine with that one. Of course you can only use 19amps per rail. Most PSU's with multiple rails have a primary 12 volt section then break them into different rails, so you cant really just add all the rails together to get total amps but usually its close I believe.

I'm running an evga sc 260 just fine on a Antec Truepower Trio 550w. I don't know the specs offhand but you can check antec's site to compare.

We've got a member here who is running dual GTX260's and a Quad on an Antec 500, I wouldn't worry about running 1 GTX on a 650.

Unfortunately, due to a lot of poorly constructed power supplies, specs tend to be inflated on required wattage/amperage.

You *cannot* simply add the rails together to get total amperage. What you want to do is find out the total amperage of the 12V rails taken together. The easiest way to do this is to look at the sticker:

The sticker clearly states that it supports 624W on the 12V lines, or 52A.

Then, we'll go look at actual power consumption measures:
which show a single 260 consuming around 260W

Your PSU is overkill and a half. Quite literally (260*2.5=650)

Hi, I will be getting a GTX260 card along with these parts, C2D E8400, 2 GB Ram, 2x Sata Drives, 2x DVDRW Drives and an Asus P5kc Motherboard.

My current system has a Spire Rocketeer 500W PSU with 2x 12v rails at 20A each and 32A combined.

I would like to keep this PSU with the new system, will it handle it? Or will I need to get a new PSU?

Interesting... just had a post on this under the Nvidia subsection about the Antec NeoPower 480W and the BFG GTX260... People seem split on that one... :\

Hey all, I got a question, that i'm sure has been answered, but I'm having trouble finding it. My new system is highly unstable. And I'm trying to figure out why.

I have as follows:

i7 core 930 2.8ghz
Corsair TX 850w PSU
EVGA GTX 470 Video Card
Corsair Dominator GT 6gb
1 x Western Digital Blue 64gb SSD (which holds my OS and main programs.)
2 x Western Digital Black Caviar 1.5TB hard drives for storage.

Most of the time, when I boot into windows, I get to the login screen, then when i type my password the circle spins and freezes and I have to reset and try again. Sometimes it will boot in, and sometimes it wont. I am wondering if this is a power issue, or driver issue. Or what is going on? I can't figure this out. Right now I only have my SSD hooked up and not my 2 Sata drives. I am having issues with them and am RMA'ing them.

Any ideas?
