Upgrading GPU, Help!

[usurper]

I was planning on looking to buy a new GPU for Christmas. I looked around and found the Sapphire Radeon 7770, which is probably what i'm looking for, but I am not tech genius so I REALLY need help before actually purchasing it. I was reading some threads on tom's hardware forums that you need a 500w PSU to be able to run it, but It was depending on the processor aswell. If anybody could help me pick out a nice cheap PSU under $100~$150, that would help me out a lot. Here are my PC specs just incase;


Processor: Intel Core i7 3770 @ 3.40GHz
GPU: AMD Radeon HD 7570
RAM: 8.00 GB
PSU: 450W

[_I_]

7770 would be a tiny step better than a 7570
what brand/model power supply do you have?

it its under 400w, a gtx750ti is the best low power gpu
a quality 450w can run a 200w gpu, gtx 760 or r9 270x
a quality 550w can run any single gpu

I could buy a 550w PSU since it's only $100 on amazon, i don't mind getting a new one. ( and to be honest I have no idea what power supply I have sadly enough ). What would you think a good GPU to be able to run, let's say, Planetside 2 on High~Ultra settings?

Non-modular PSU[pcpartpicker.com]
Semi-modular PSU[pcpartpicker.com]

The difference between modular and and non modular PSUs is that you can detach unnecessary cables so that they won't take up space inside your computer, and you can attach them again if you need them.

Wattage is nothing to worry about, you wont ever need that much for a 7770, TomsHardware honestly is filled with people know really have no idea what they're talking about.

If I were you I'd go with the XFX power supply and use the extra to buy a beefier graphics card.

GTX 750 Ti is more powerful then HD 7770 and runs fine with 300-350W PSU.

Better would be to get 550W XFX PSU and R9 270X or GTX 760 card though.

There is currently crazy deal on this PSU at Newegg:

Which resolution are you going for?

Planetside can run on high with the HD 7770 and GTX 750 cards.
From personal experience i would go with nvidia cards.

I was planning on buying myself a 1920x1080 monitor with 144Hz

Nvidia cards are so much better, mostly because of Nvidia GeForce experience since Gpu updates and game optimization is so much easier to do with Nvidia.

Then you need something stronger like GTX 770:

Google on how to check ur PSU , it would rly help with the pc specs, if u already have a good PSU u won't have to get a new one.

Keep in mind gtx770 is over 400 dollars plus he PSU and monitor. Make sure u do ur math

a quality 450w can run a 200w gpu, gtx 760 or r9 270x
a quality 550w can run any single gpu

The hell are you talking about? Minimum for a 760 is 500W. You pulling this out your ass or am I missing something here?

760 is 170w
most systems are under 300w without a gpu
3g i7 1155 is 77w, will be around 250w for the system without the gpu

total would be 420w
under what a quality 450w psu can deliver

XFX is made by Seasonic, beats cheaper Corsairs like CX series in quality by a mile.
