I recieved my new psu a couple weeka ago. It came in the mail but I wasnt able to plat around with it till I got off at midnight.
To make it short, I swapped out my corsair hx1000w psu for this new 850. I thought my psu was going bad so I got a new one. I swapped it out, hooked everything back up, hit my power button, heard a slight pop, but proceeded to let my computer boot. Low and behold, my computer did not boot due to there not being anything to boot from except the cd drive. Finding it strange, I rebooted my pc and tried again. Same thing. I put in a install cd to format my freshly fried hdd, couldnt even do that.
By coienidence, my psu fried my hdd and my lamtron fan controller( 4 channel, 12v per).
Maybe it was a surge? I usually wait a few secs once I hooked up the psu and before I flip the psu switch. Just to give the electricity the time to settle where it needs to go.
So I grab my bros older seagate 7200.9 hdd(2007 series). I hook up the sata power and data cables, turn the pc on. Instantly see smoke coming from the sata connection. Turn everything off and its been off since then. That was last week. Im in between paychecks and tight on money to get a new hdd and fan controller. Fan controller isnt that big of a problem as ill just use the mobo headers for now.
But if my psu is messed up, I dont want to waste the money buying hdds just to keep frying them.
How would I go about testing the psu?? I can get a volt meter and check it, but what am I looking for exactly?

You can check the voltage but you need to "hotwire" the PSU to turn it on when it's not connected to anything..Do that by connecting a jumper wire from the PS_ON (green wire) terminal to any COM (black wire) terminal..Just remove the jumper to turn it off again..Some pinout charts for the various connectors are here and here along with the 12V, 5V and 3.3V tolerances as well as links to ATX12V Power Supply Design guides.. Here is even more pinout charts..The COM terminals/black wires are ground.

That was more confusing than helpful. I know what the cables are. I need to know why my parts fried by just switching psus. I used the same cables from the old psu. There shouldnt be a cable issue

You used cables from the hx1000 on the 850 G2? Bad move.

Power supply cables are proprietary between manufacturers. Even cables between our power supplies aren't always interchangeable either, for example you wouldn't want to use the 24 pin from a 750G with the 1300w G2. This usually does result in damaged components.

So your saying my old molex to sata cable from my old psu doesn't work because of the oem? When the 850 doesn't come with more than one molex cable. I need two. One for my pump, the other for my fan controller. The cable has more molex, I think 3 but none of then reach the other parts. So you guys are saying I'm stuck with what I got? Endless cycle of burning parts up because I dont have enough cables from the new psu to power all my components? Edit: im reusing 6pin and molex/sata cables to fill the lack of new ones from the new psu. Id never use cpu/vga or mobo cables

no what they are saying is you should have used the cables that came with your new power supply. some makers change the wiring at the power unit the side that plugs into your hardware is always going to be the same tho but the side that plugs in to the power supply can and is different from unit to unit.

I used all of the new cables that I could. I had to reuse a old 6pin to molex for my fan controller and a 6pin to sata for my hdd. One that came with wasnt quite long enough. And thus now im down a hdd and fan controller. So really, its not my problem but evgas for not supplying enough proper cables... Who would think one 6pin to molex would be sufficient for the computers nowadays!?
I have a new hdd on the way. If I hook it up and use evgas cables and it ruins a brand new hard drive. They should be paying for my hdd and expect an express rma from me.
This is stupid, ive been out of a computer for almost 2 weeks

According to the product specs, unless I am reading it wrong it says there should be 4 4-pin peripheral cables. So not sure why you got 1? Did you check the manual to make sure all the cable were included? As other say, as trivial as it sounds, even on molex cables, different PSUs can and do unfortunately have different pin-outs.

There is exactly one cable for every slot. Motherboard, cpu, vga. Then 3 extra vgas, 1 extra cpu, 3x sata 6pin, and one Perf 4pin to molex. It has 3 or 4 molex hookups daisy chained on that one cable.
Sata 1/sata2/sata3/perf 1 all located bottom left under the motherboard hookup.
Unless I got some kind of bootleg psu. I would like more molex cables. Them being daisy chained does me no good

My hard drive came today. Just picked up a cheap 160 gb seagate for $35.
If I hook it up and the cable that came with the new psu ruins this one. Im going to be one mad evga customer

You should not have any problems as long as you use the cables that came with the psu.

Im formatting with my win7 64 atm. Everything is running smooth.
I just dont understand why my other hdd messed up. I used the same cable as I am now.

Had two intel drives burn up for no apparent reason on my system. Have not had the same issue with my vertex drives. Things can burn out for no apparent reason at any given moment in time unfortunately.

Well, after a few days of making my hard drive and video card cry testing out some games. I believe that my problems have subsided. And in my case, I still dont know what was causing it. But a new hard drive and power supply fixed whichever part I had going bad.
Will do a few more days of heavy testing to see if it actually subsided
