Power Supply HELP please

[thechankwhoganks]

Hi guys,                  *Warning My english is not strong, since it is my second language
I have a concern about choosing my power supply. I'm looking at a EVGA 1300watt G2 PSU and after some research I stumbled upon a warning about checking my peripheral connectors and something about SSD and hard drive connectors because the 12v rail is too powerful and that it might blow those items from a short? it has 103A but I'm not sure how to check this. My system is a i7 3770k, SLI 780 ti's, 2 SSD in raid 0 and 3 Hard drives, and full custom waterloop. Right now it's out of commission since my 850 watt power supply broke. I have a chance to get 1300 watt PSU for 180  so I'm thinking why not.

You don't need that many watts Just get another 850 watt if it worked fine before.

It will not harm any components. Amps are not volts, having 'too many' doesn't cause damage. Think it like each component 'sips' the amount of amps required as long as the voltage is correct.

oh I see thanks for the info, I was just confused because the review that I read said to be careful with high power 12V rails because it could fry my components, so I should be safe then.. Would a power outage hurt my components or my PSU ?

Well that is true, I just thought having more headroom, and having my powersupply having to work less would be better and that the 1300G2 from Evga is only 40$ more than a 850 watt psu. So why not ?

A high strong 12V rail is complicated for the PSU manufacturer, not the user; as you need very high quality inner components (caps, etc) to reduce temperature and instability; as well as to make the whole thing work properly. If the PSU maker delivers a good product, then it's perfectly safe for use. Now, I wouldn't trust Diablotek with a 100+amp 12V rail...

Short answer, if it's well within your budget, yeah why not. That EVGA unit is a great psu,albeit 1300w is a bit overkill for your system but nevertheless shouldn't be a problem at all. You can even do quad SLI should you wish to.

such high wattage tho..the psu probably won't be operating at a good efficiency

a 850 would be more then enough...max 1000w

so as long as the efficiency is good too? I read a review that at 10% load it had 87% efficiency, but I'm not that knowledgeable about PSUS, I normally just buy w.e 850watt or 1k thats 80plus gold . So I wouldn't have to worry about a power outtage shortage ? as long as the manufacturer is good?

this is where I getting the information, but somethings I don't understand http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story3&reid=349

850W - 1000W is more than enough, 850W ideally
