Ok so here are my system specs:

PSU:coolermaster RS-460-ASSA-D3 (460 watt)

http://www.techenclave.com/community/threads/cooler-mas...

You can see from there what it says onto the sticker of my psu :) (About the railways voltage and such..i dont really know much stuff)

CPU:intel core 2 duo E-8500

MOBO:GA-EP45T-UD3LR

RAM:2 gb
HDD: 500 gb 5400 rpm

P.S i currently have nvidia geforce 9500 gt and i want to upgrade to hd radeon 7770.also i think that 9500 gt needs 50 watt at full load:) (also i dont know if my psu has an 6 pin pcie connector that i think hd 7770 needs)

Hope i was straight and understandable cause i dont know very much from pc :)

For a system using a single Radeon HD 7770 GHz Edition graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 23 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum...

The Radeon 7770 has a maximum power draw of 80W.
Your PSU will be able to provide this easily.
Your PSU has the required PCI-E 6 pin connector.
Refer to the following page on your PSU:
http://www.coolermaster.com/service/support/model/RS-460-ASAA-D3/

When you pick a brand of card, look at the dimensions. You just need to check that it will fit in your case.

Usually I would tell someone to get a 7770 over a 650TI or 650 TIboost, but the Nvidia cards use a lot less power and you're cutting it kind of close. So that might actually be a better option for you. Definitely do the memory before (or at the same time as) the Video card as it will provide more usefulness than the card will. But if you're tied to the 7770 it will be close but should work assuming the PS is still putting out what it did when it was new. I just hate to cut it that close.


◾500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended7

Not saying it won't work just saying it'll be boarderline.

I am on a tight budget so i dont have money to buy also a psu...:(Also i cant afford gtx650 cause its +25 euro in my country(from hd 7770) so all in all i am between hd 7770 and hd 7750..Also VincentP said that hd 7770 has a maximum power draw at 80 watt.my nvidia 9500 gt that i use now has 50 maximum power draw.so we are talking for 30 watts difference.Also to my country hd 7770 only costs 10 euro more than hd 7750 and i know that hd 7770> hd 7750 so thats why i do all these questions..so i can get the best for my money (P.S mu psu is 3 years old and the company has 5 year warranty so i guess its ok and it hasnt lost its effectiveness :) ) Plz help me and sorry that i have so much questions :)

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The Cooler Master Real Power Pro 460W (RS-460-ASAA-D3) power supply unit, with its maximum combined +12 Volt continuous current rating of 32 Amps and with one 6-pin PCI Express supplementary power connector, is more than sufficient to power your system configuration with a single Radeon HD 7770 GHz Edition graphics card.

Ok supahos i understand what you are trying to say :) thank you very much for your time !!! ko888 i didnt really undrstand what you said.about the amper thing and the overclock..my DC OUTPUT is

3.3V-->20A

5V-->20A

12V-->18A

12V--> 18A

-12V-->0.5A

5V-->2.5A

and ac input is 100-240,8-4A and 60-50Hz thats what it says on the label :) You said at your last paragraph that i got 32Amps maximum..I really dont understand all this stuff but i am writing in detail the specs of the psu in case u missed something:) So i really can run asus hd7770? thanks in advance and sorry for your trouble :)

See the 384W under the two +12V rails? That's the combined +12 Volt continuous power rating.

384 Watts ÷ 12 Volts = 32 Amps

Yes this PSU has more than enough capacity to power your system with a Radeon HD 7770 GHz Edition graphics card.
