Powering my gtx 560?

[wburton]

I'm building a cheap/ newish but rather old computer out of some core 2 duo parts I had plus some new stuff like a psu, case and gpu. I'm building this computer because why not. I only spent $160 to build it and it should play all the games that I care about even if I decide to add more ram and a quad core cpu it still suits my needs. I don't really care for anything newer because I'm not so big on big title games. So I just got my evga gtx 560 2GB gpu in the mail today and I noticed that it had a 2 x 6 pin psu connector on it and my logisys 550watt psu. My psu only has 1 x 6 pin psu connector. According to the psu packaging that 1 x 6 pin provides 12v and 25 amps. I'm not sure if just that alone is enough to power that card but I also have 2 x 4 pin psu connectors and two molex psu connectors. I was wondering if it were possible to scrape by with that one 6 pin or if I got a 2 molex/ 4 pin to 1 x 6 pin adapter if it would work ok?

**Note about that psu**

I've read both good and bad reviews about that power supply but I speculate that people are buying those to cram into new or higher end builds. These units appear to be useful for old, low/ med spec desktops or desktops that are used by avg users at home or in the office.

2X 6-pin means you need 2X 6-pin. Sorry mate.

Here are my upcoming dated pc specs:

Intel Core 2 Quad Q9300 Cpu
Zalman low profile cpu cooler.
Evga Nvidia GTX 560 2GB
Intel dq45cb motherboard
4 x 1 gb ddr2 pc2-6300/800mhz ram
Seagate 600GB 2.5" hdd 5400rpm
DIYPC case with two 120mm led fans and one 90mm fan.
750watt Antec Truepower PSU

You may have problems with the CPU and RAM bottlenecking the graphics card. You may also need to change PSU, you'll need 2X 6-pin connectors for that GPU to work.

get a better power supply
logisys is not good at all

corsair cx430 is better and can power the 560
its often $40/20ar on newegg

or evga 500b-600b are often $40-50 on amazon

Logisys = toss it in the trash (recycle it properly though), never buy ones like those.

Yeah you know what I agree with you. I read a bunch of reivews on the product last night and it seems to only work ok as a replacement in old (5-7 year old) business desktops. So I started a return for that cheap psu and I ordered a used Antec 750watt Truepower psu on eBay. I was surprised that it only cost me $15 more and it was a good working unit according to the seller. It was just missing the power cable which I just so happen to have.

I guess thats it for this post. Problem solved. Thank you guys for your advice.

I decided to throw in a Q9300 cpu into the cart with my new used Antec psu. I will probably order 8gb of ram which is only under $20 now next month or two.
