Looking to upgrade my gpu

[Mariushattingh]

Hi all, this is my rig at the moment. I7 3770k, 6gb ram, gtx 750 1gb 450watt psu. Want to know what gpu to upgrade to so I can play most if not all newest games on ultra on 1920 res. By the way im upgrading my ram to 8gb.

Hello... I use this chart to compare price and performance... your MB/CPU should be able to run most of the GPU's on top of the list... But your +12Vdc current rating of your Power Supply will need to be checked for the higher output current needed for some of these cards... your GTX750 was only about 60watts/5amps... some of theses cards will need much more B /

My current psu is 450watt

What is the make and model of your power supply?

Im sure its raidmax not sure about the model have it for a few years now

Hello... There will be a electrical spec/label on the PS it's self... open the case and snap/post a digital of it... There is more than One Voltage used in a Power supply... and they get added up together for a product Number/name... you will be using the +12Vdc from it for your CPU and New GPU. Also you will need some 6 or 8 pin connectors to connect to these GPU's. So it's a good thing to Look before you Buy, and have all your electrical verified before.

Couldn't manage to upload a snap not sure how but this is the following info on the label. RAIDMAX ATX12V Power. RX-450k (Ky550ATX) ATX 12V DC Outputs. +3.3v, +5v, +12v, -5v, -12v, +5vsb
10A/5A, 28.0A, 34.0A,210A,0.5A,0.8A,2.0A,450W

I have decided to save and go for a gtx 1070

Hello... THx... you have to use an IMG uploading site and then post the link/address here B )
Basically for the math of it I need the PS +12vdc current rating, and the CPU and GPU to be used.

77(CPU)+150 (GPU)=227 watts /12vdc = ~19 amps. min needed from PS.

Does your PS have any 6 or 8 pin PCIe power connections?

That's cutting it close. If you can get a better power supply, i'd pair your i7 cpu with a gtx 1070. If you can't replace the power supply, the best gpu upgrade I can recommend is a gtx 1060, as it has a low tdp of only 120watts.

 

[Mariushattingh]

Which power supply will work with 1070 best?

 

[SgtScream]

A good quality 500w power supply will do just fine.

Hello... I would suggest looking for 25 or more AMPs on the +12VDC PS rail. And picking the Video card out first... because of the number of 6-pin and 8 pin power connectors on them... they vary by maker/model... some need two 6's or two 8's... or one of each? this way you will be ready for a fast install.

You may be able to pair that power supply with a AMD RX480 8 GB card and save a hundred dollars. It uses a little less power than the GTX 1070 and almost catches it in Direct x12 titles. here is a link to the power consumption results. http://www.anandtech.com/show/10325/the-nvidia-geforce-gtx-1080-and-1070-founders-edition-review/30
