Hi,

I have an ASUS AM3+ M5A88-M Motherboard with Phenon II 1055T Six core processor with NVIDIA GT630 2 GB PCI-EXPRESS VIDEO card. I have connected my PC to a LED FUll HD TV's HDMI port through the NVIDIA GT630's mini HDMI to HDMI cable. I have 2 SATA Hard disks and one Internal SATA DVD Writer and I am planning to add a SATA Blue Ray Internal DVD Writer. I also have a couple of USB external hard disk attached to my PC.

I have a Hunt Key 500 watt SMPS. I am planning to upgrade to AMD FX-8150 processor along with four 4 GB 1866 MHz DDR3 RAM modules.

Will my ASUS M5A88-M Motherboard support four 4 GB 1866 MHz DDR3 RAM modules if I upgrade to AMD FX-8150 processor. Will my 500 watt SMPS be able to take the load or should I have atleast a 600 watt SMPS.

Please repply as soon as possible.

Thanks and Regards,
Sriram.

From http://www.asus.com/Motherboard/M5A88M/#specifications

*4 x DIMM, Max. 16GB, DDR3 2000(O.C.)/1866(O.C.)/1600(O.C.)/1333/1066 MHz Non-ECC, Un-buffered Memory Dual Channel Memory Architecture
* AMD FX Series CPU on this motherboard supports up to DDR3 1866MHz as its standard memory frequency.

Memory won't be a problem.

Hmm.

From here http://www.legitreviews.com/article/1414/12/ it looks like the Phenom draws about 236 watts under load and from here http://www.hardocp.com/article/2011/10/11/amd_bulldozer_fx8150_desktop_performance_review/9 the FX seems to pull about 452 watts under load.

That's about 216 watts more than the old system.  So I don't think your 500 watt or 600 watt power supply will be sufficient.

Hi,

I presently have a 500 watt smps. Some smps online calculator tools informed me that 500 watt smps is sufficient for amd fx-8120 whereas other online smps calculator tools informed me that I need atleast a 600 watt smps.

Based on 90% cpu utilization without overclocking, can you please provide me the exact approximate smps values for an FX-8120 AMD CPU. Can I try to take a chance by trying to install the FX-8120 processor in my 500 watt smps?

Please reply as soon as possible.

Thanks and Regards,
Sriram.

I presume you mean the FX-8150 rather than the FX-8120.

Yep you can try.  The figures I quoted earlier of 452 watts is too high.  Those are overclocking figures.  Apologies.

If you don't overclock you should only be using just under 250 watts maximum.  Your power supply should have no problems with that.

Got information on power supply from using Google with the following query:

FX-8150 review

Looked at a number of reviews and they didn't go over the 250 watt mark.

Hi,

I am closing this question because my computer hardware dealer installed the eight core processor on my 500 watt smps and it's been a day and my system is working fine.

Thanks and Regards,
Sriram.
