Issues with AMD budget build (FM2)

post #1 of 5
Thread Starter 
Hi guys,

a friend of mine wanted to replace his 10+ year PC with something new but he can´t really spend a lot. We went with a FM2 build with dedicated GPU with the following components:

- Athlon X4 750K
- Asrock FM2A75M-DGS
- Kingston HyperX 1600 4GB
- Gigabyte HD 7790 1GB
- Generic Tacens 500W PSU
- Aerocool VX3 case
- SATA 3 HDD and DVD writer (reused)

We assembled everything and the problems started:

- Switched it on, all fans working but no signal through the HDMI nor the DVI of the HD7790, the thing wouldn't even POST.
- Tried a 650W PSU just to be safe, no luck either.
- Tried 2 different GPU´s and still no POST.
- Tried the RAM stick on a different machine and it works.

So after all that I assumed the motherboard was faulty and returned it along with the PSU (bad quality) and I am waiting for:

- Asrock FM2A75 Pro4-M
- Aerocool Templarius Imperator 550W (mobo and PSU are 25$ more than we initially wanted to spend but better be safe than sorry).

The only other thing that I can think about is that the Kingston RAM doesn't work on that mobo, however the "memory compatibility list" shows that same RAM as compatible...

Any help?

The memory could have not worked on the board due to the motherboard being faulty. another possibility is that you could have a bent pin that you didnt know about. Anyway, Kingston memory has really low failure rates, so i doubt it was the memory that was the problem.

Get a better psu. a psu should be an investment well spent. Look at this thread for quality, recommended psu's: http://www.overclock.net/t/183810/faq-recommended-power-supplies

The memory did work on an Intel board no problem, so that rules out the Kingston.

The thing is that my friend's budget is really tight and we don't have US prices here in Spain, and on top of that we are already overspending because the HDD we were originally going to use died last week.

We have to buy the PSU from the same shop and the most sensible choices (money wise) that I can think of are:

http://xtremmedia.com/Cooler_Master_GX_450W.html
http://xtremmedia.com/Templarius_Imperator_550W_80Plus_Bronze.html

Those should be more than enough to drive a 7790, right?

Well I do a little bump to say I ordered:

- Asrock FM2A75 Pro4-M
- Corsair CX430 V2 PSU 80+ Bronze

The only thing left to see when the parcel arrives will be if the PSU can drive the 7790 + X4 750K. Gigabyte says that the PSU needs a 450W (or greater) PSU but I´ve seen reviews where the 7790 + i7-3960X draw an average of 259W (196W in Furmark).
