Will Zotac Gtx 750ti work with 450W Local PSU

Ok so here it goes...really in need of answers as fast as possible . I am planning to upgrade my GPU from my Nvidia GT 610. The PSU that I have is FRONTECH ATX P4 JIL-2414A . Its a 450W local PSU . Image : http://imgur.com/IJgYnZo

It has 19A on the +12V rails and no 6pin connector.


So I plan to buy Zotac GTX 750ti 2gb DDR5 as it does not require 6pin connectors !!
Now whatever information I have gathered on the Zotac Gtx 750ti 2gb DDR5 is that it is a very power efficient card,does'nt require a 6pin connector , has a minimum PSU requirement of 300W with 20A on +12V rails (info from Nvidia Website).

My other PC Components are as follows :
Intel core i3 2120 @3.3Ghz
3 X 2gb DDR3 1333Mhz RAM
GIGABYTE H61M D2H Motherboard
Seagate 500gb HDD

So my question is, will this Card work on my PSU ?? How much current will my system draw from the +12V rails when gaming ?? Is there a high risk if I use this PSU with this card ???? Please Help !

Even if that power supply is only efficient up to 300w you will be fine, my low power pc which uses a 350w seasonic power supply from another system, a low power haswell i7, and the 750 ti. All of my stuff uses only about 134w of power, and that is with a slight overclock on the video card. So 450w even if it isn't a super good brand you still will be fine.

Relieved to hear that ........ thanks man ...... !!! and btw i dont have any optical disk drives (i.e CD or DVD drive ) ..so i save a bit of power over there too right ?? and another thing ............ i was thinking whether the +12V rails current might be a bit of a prblem ............ can u please tell me whats urs +12V Amperage rating of ur 350W Seasonic PSU ??

The one on the computer I think it is only like 25 maybe 30. but the max wattage for a pci-e slot is about 72 or 76 watts, which is only about 6 amps, so you are more than good. Just make sure that you get a single fan cooler version of the card so you won't need to use any power cables to connect the card. So you will be perfectly fine, I have even seen people use something as low as a cheapo 250w power supply and that card still ran fine.

You won't have any problems with it, the card just runs off power from the pci-e, I have power supplies that are 10 years old that could power something like that, don't worry about it, just go out and buy it. Some people just bug the crap out of people to buy a new power supply not knowing that it is the efficiency that separates a good from a bad, your system won't even be using 300w so even if your power supply was only efficient up to 350w you will still be fine for years.

tHanks for the info man ....was really worried ............. i reallt did'nt want to spend so much money on a PSU ....so was looking for a card that can run without the 6pin ............... and since i only have a 720p monitor ...... i hope to play games on ultra with these card and 6gb RAM!!!!! :) 

The PSU worry is off the table as of now !! :)
