Will my PSU run my new GTX 760?

[Michael Tinervin]

I ordered a new evga gtx 760 SC edition and I just got it from newegg yesterday. EVGA says I need 30amps on the 12vt rail, but my current PSU which is a RAIDMAX HYBRID 2 RX-630SS 630W ATX12V V2.2/ EPS12V, says it has +12V1@22A x 2. Can I use both of the 12 volt rails to my new 760 to give it the required 30 amps or will that fry the card. At the moment I don't have the money to buy a new PSU, but I really don't have the money to have to replace my new graphics card.

GTX 760 has minimum recommended system power of 500 watts. dont worry about amperes

The short answer is Nope. If it does run, you will get far less than optimal performance from the card. There are no provisions to hook both to the same card. You will need a new PSU for proper card performance.

That's what I was afraid of, I was hoping on the off chance that I could avoid having to buy a new PSU, but looks like that's exactly whats going to have to happen. I don't even want to try to use it until I get what it needs. Like I said, I don't have the money to have to replace new new graphics card just yet. On the upside of a new PSU, if I get a good one I can save up to buy a second 760 for sli. lol Thanks guys.

So I contacted raidmax tech support and asked them about it, and this is what they said, use both the 6 pin connecters and it would provide the 44amps that the GTX 760 needed. I'm almost afraid of putting it in, don't want to kill the card or over tax the PSU. Anyway here is what I got back from them on this.

yes, plug both connectors to your graphic card that provide you 44amp

Subject: Question About a HYBRID SERIES RX-630SS

Hi I have a question about one of your HYBRID SERIES RX-630SS power supplies. I bought one of these back in 2011 from Newegg.com and have been using it happily for all this time. It has never given me any problems at all. Recently I just bought a new Evga gtx 760 SC edition graphics card and was wondering if your power supply would be able to power it. The graphics card says it needs 30amp on a 12v rail and it needs both a 6 and 8 pin connector to power the card, I was looking and I saw that the HYBRID SERIES RX-630SS produces 22amps on a single 12v rail, but I have to use 2 connecters from the power supply. So I was wondering if I use both the 6 pin connecters and they supply 22amps, would using 2 give me 44amps for the card or still just 22amps? I can build a computer but I'm still hazy on the specifics when it comes to power supplies, I've looked on the net and I've gotten both "yes it will" and "no it won't". So I'm just a bit lost and confused. I really don't want to damage the graphics card or my system by doing something I shouldn't, and I don't want to have to spend a ton of money to buy a new power supply if I really don't need to. Any help would be appreciated, and I would be grateful if you could let me know the definitive answer because the internet is no help at all. Thanks in advance Michael Tinervin.

Hi Michael, Did you try the suggestion from raidmax tech support? If so, how did it work out? I have a similar problem getting my PC to start having just installed a Gainward GeForce GTX 760 2GB and connecting my modular PSU, a MIST 1000W. It has three available 12V rails of 20A each.

Hi. You Power supply has a 6 pin connector as well as a 6+2 pin connector. Plug both in as that is neccessary anyway. If the graphics start getting a bit hangy or slow when they get intensive, then you will need to change out the PSU as you are not getting enough on the rail(s). I know this from personal experience.

Hi coastie65, my problem was caused by the usage of 6 pin connectors from another power supply (Corsair). Evidently, they cannot be used interchangeably! Once I connected the two 6+2 pin connectors that came with the MIST power supply, not using the extra 2 pins on either, the computer started.

My next problem had seemingly to do with a BadDriver, where the Windows 7 autorecover tool was not able to repair any problems. While thinking that this had to do with me not uninstalling the old graphics card before installing the new, the error message was entirely misleading. Feeling rather stupid, I finally found that the power cable to the hard drive had become loose!! Connecting that properly, the system booted normally to Windows and I was able to install drivers and other software for my new graphics card.

Loose connections can be a headache for sure. Have run into my share of them to the point that is usually the first thing I check ( depending on the issue ). Don't know how you were trying to use Corsair connectors though. Those things are usually pretty much standard across the board.
