1000 amps?? Wow, man what kind of a PC you running there?? Hacker system with multiple outputs??
Yeah, Josh - I haven't been keeping up SPECIFIC details with the video card word since 9000 series, but looking at newegg they provide your wattage and amps recommended now.
I always used this site to calculate a decent "Psu wattage" when I don't estimate by volts & amps for the watts - this one does most of the calculation for you:
Antec Power Supply Calculator
The corsair you posted looks like it's fine, 52A@12V. It's single rail too. Some people prefer single rails, other prefer dual, or quad rails. I think its personal choice up to you what you want.
I haven't used corsair personally before except for work, but my home choice is always antec and sparkle/fortron. They are like my "brand of soda" pick if you know what i mean. Never have problems with them.
Most antecs I use last up to 5+ years and never had a problem, always only needed to switch PSu and nothing else died. In the past, when I had junk PSU like raidmax and that crap, stuff fried from my systems.
Two things I forgot to mention previously in my PSU post:
1. There's also a thing called the regulation, if you look around manufacturer website you will see it. What regulation means that there is this % of error that it might not actually run at that power.
2. PSU juice dies after the years it is alive. This is called the
capacitor aging, you will see that on the antec calculator. After one year you should increase your % up each year due to the aging losing off a few amps.
For instance, I'll give you this example.
I use this PSU:
Antec - EA 430
I use this as my system, non overclocked.
Quad Core Q6600
G92 8800GTS no SLI
2GB DDR2
1 SATA
2 Optical drives
120mm fan
2x 80mm fans
My PSU has dual rails. 17A on Rail1, 16A on Rail2. It can provide a total of 33A. However, I'm not taking regulation into account. Regulation is 5% on both rails. so that means 5%+5% =10% of 33A should be taken off for regulation - this means 33A x 10% = -3.3A = ~30A to use. My 8800GTS I think uses either 22A or 24A at max conditions, I forgot, so if I said it's 23, I have 7A leftover on the 12V to power the rest of the system. That's plenty enough. Each year, I lose about probably 1A. So it will be by year 3-5 I should look into replacing.
I am just on borderline, but not quite. I don't use my 8800GTS at maxed out settings often because I rarely game anymore these days, so I am actually using less than my stated amp.
I hope this helps you out. I can't speak for corsair because again, I haven't used outside of work pc's. But I have heard good things about them and I can say you probably should be ok with it.
