Will my PSU be enough to run fully the Powercolor R7 250x 2gb GDDR5?
 
PC specs:
MB: FM2A55M-VG3
APU: A8-6600K
HDD; 500GB Seagate 7200RPM
RAM: 2x4GB 1600Mhz
OS: Windows 10 x64
PSU: 500W Thermal Master 65% Efficiency 20amps on +12v rail
 
The PSU came with the case which is Cooler Master and has no 6 pin connector, but I do plan to get a 2x molex 6 pin cable. in Game Debate it says that it takes max power of 80 Watts.

:welcome:   zarxy,

 

Sorry but no it will not as when independently tested the said PSU only produced 240W, while that is terrible it is not uncommon for inferior brands to put out significantly less than what is claimed by the manufacturer, you can confirm the results for yourself by checking the PSU Review Database link in my signature below.

 

Be sure that any replacement PSU is a minimum of bronze rated else you will be purchasing guaranteed junk, the Corsair CX 500 is an example of what you should be looking for.

Thanks for replying, so my PSU is horrible, what if I went with Zalman PSU 500W ZM500-LE Efficiency 81%, cuz I cannot afford for more than this and it has decent price. In PSU Review Database it says that it has Max. Load +12V 444 W, would that be enough to supply my system with power?

Not sure where you read that the PSU has an 81% efficiency rating as it is not certified, more junk I`m afraid, bronze rated PSU as a minimum or be prepared for it to pop and possibly take out all of your other hardware along with it, take a look at the Corsair video here which shows poor quality brand PSUs being tested and you will understand why I stress the importance of only using good quality brand PSUs.

 

You are welcome btw  :)

Haha the video was interesting and funny, anyway I understand how important it is, but I cannot go over the 50 Euro prices with the money I have, so how about the RAIDMAX RX-535APRX-535AP, in PSU Review Database it says 80 plus bronze for this model and max 432w, would this be worth buying since it has  80 plus bronze? It also comes with

Circuit Protection: Over Voltage 
Short Curcuit Protection 
Over Power

 

 

Edit: Th size of this PSU won't fit my case though, as my current PSU is 140x150x86 while the Raidmax is 150x165x86. Will have to look for another.

 

Edit2: In this case I'll go with the Zalman PSU 500W ZM500-LE, it also comes with Protections: Heavy-duty protection circuitry of OVP, UVP, OPP and SCP.

The final decision is yours obviously but see if you are able to obtain the PSU here within budget.

That power supply you suggested is not found in my country, but there is EVGA 430W Active PFC 80 plus certified, but it shows that it's max 408 W, not sure if it will be best choice, although it says in evga website that it's 430w continuous power.

Looking at the review, I think I'll go with Zalman, as the Evga 430w sounds more like it won't fully power the r7 250x, thanks for trying to help, much appriciated.
