I have a Corsair CX 430 PSU and i want to get the EVGA GTX 660. Would my PSU be okay for it? It has one PCI power connector. What are these two 6-pin PCI Express power adapters for and do i need them? I thought all i do is connect the one from my PSU.

Here is Guru3Ds power supply recommendation:

GeForce GTX 660 - On your average system the card requires you to have a 450~500 Watt power supply unit.


If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina. Source - http://www.guru3d.com/articles_pages/msi_geforce_gtx_66... it might be o.k. as long as you do not overclock your cpu and card you should be o.k.

the 6pin pci-e plugs go into the video card for the extra power needed that the pci-e slot can't deliver. if you look i think the card only needs 1 6pin plug. the PS delivers 32amps which is lower than i would use but should work. how efficient and how much stress it would put n your system i don't know.

On second thought i am taking back what i said.I wouldn't feel right if you killed your rig over my advice.That being said i still think it would work but why risk it.Better to be safe then sorry.

it should work fine.. even if you use Newegg's psu calculator, it comes out to about 436 watts and if you psu is 80+ bronze,silver, or gold then it will be fine. as for the connectors you will need pci-e to 4 pin molex conversions

Believe me, I've seen a guy running GTX 660 in that PSU.
But if you ask me, then I'd not risk my GPU to that PSU.

I just bought a 550 ti on clearance for 80 bucks. I just plugged in the PCI-E power cable from PSU into the card. I dont need those molex ones do i?

the 550ti actually uses a few MORE watts than the 660 :p 

i think you'll be ok with either but the million dollar question is:

what are your specs? cpu, ram, hard drive(s) case fans(?).

The builder series are made by CWT and are mediocre PSU's at best. Reviews of the builder series have found that these are unable to deliver their rated wattage. While I do reccommend them in budget gaming machine builds, don't trust them to deliver they're full rated wattage. I.E., don't trust a system that needs more than 350w under full load to the CX 430.

We wrestled 522W from the unit before it would switch off. The overcircuit protection system worked fine and it shut off safely. A really good early indication of what is in store.

not saying its ok to overload a PSU but i don't know what reviews you are reading . . .

2.8GHz AMD Phenom II 830 Quad-Core (95 watts)
8GB (4x2GB) RAM (2*4 watt=8)
1TB 7200rpm Hard Drive (5 watts read/write)
SuperMulti DVD Burner with LightScribe (meh, 8 watts)
ATI Radeon HD 4200 Graphics (not being used but 15 watts for the AMD chipset)
802.11b/g/n Wi-Fi ( 5 watts(?))

136 watts - so your fine with the 660 (110 watts) or 550ti (120 watts).

i had the inclination you were thinking of a coolermaster extreme power plus. they must had not paid CWT enough to build those . . . complete fails.

cheers.

if that really iss your pc, then forget about the gtx660, your cpu will be bottlenecking it big time. You could run a gts550 and not notice the difference as your cpu will be slowing everything down. I suggest you split the $$$ difference of the price of the 660 and upgrade your cpu and get a low-mid range graphics card for a more well balanced system.

I'm looking to bring my PC to this gen of specs. I "built" it up back when the 8800gt and those were coming out, so I've been hanging on quite well with that since then.

I'm having to re-learn what all is out there now and I'm not sure if my PSU is good to go for another round of video cards or not?

That is my exact PSU, and I'm looking into the 660 ti. What do you guys think?

Thanks!

I bought a 550 ti and it's working pretty good. I'm not worried about playing FPS games such as Battlefield. I only play RTS games such as Company Of Heroes and Starcraft.

the 550ti is not bad especially if you picked up for $80. you can get some decent frame rates ~40/45 with some setting turned down in most any game except metro 2033.

I maxed out Company of Heroes and i am getting 60 fps.
