I will be upgrading my CPU, RAM and mobo very soon. I'm not sure if i will need a more powerful PSU.?

750W is more than adequate. A regular i7 system only draws around 400W, 750W gives enough overhead and power in case of any increases in wattage due to heavy load.

Of course, I'm taking into account the fact that your PSU is stable, reliable, and accurate.

I'm running my i7 920 and a 4890 with pretty much everything else you have on a 700W OCZ PSU. Only difference is I have two TV tuners.

Internal sound cards are adequate and good enough in most circumstances. Though It's not plugged in into any epic home theater system so I wouldn't have any use for a sound card.

Computer power supplies are way over-sized. If you do the math you'll see. A HDD consumes about 30-45 W max. Even the most power hungry processor uses 200 W on full load, which is rare, even if you're rendering video files. Video cards can consume 270 W on full load, which is also rare. Memory uses 20-40 W per DIMM. Optical drives use 35-50 W. The remainder of the motherboard can use up to 200 W. So, that's (45*2)+(200)+(270)+(40*2)+(100)+(200)=1040 W absolute maximum load, if everything in the box is running at full speed. But that's impossible unless the machine is a busy server. A desktop cannot use all the drives continuously, and drive the video hardware full blast, load the processor to 100% continuous load, and drive 100% of all the memory all the time. One person can't do use all that simultaneously. Power supplies are made to produce momentary peak outputs 150% of the max. continuous output. That means a 750 W PSU will output ~1050 W for a second or two. If the 750 W PSU is quality, it should be perfect. Realistic power consumption for a modern gaming machine is ~600 W continuous, because either the GPU and video memory are working at full load, or the processor and memory are at full load. And memory can only be accessed one row at a time.

It is possible you have unseated a device from the motherboard, so check everything is pushed in tight. I would reset the BIOS using the CMOS jumper. It could also be that your BIOS doesn't support this CPU so check it does and if possible get the latest BIOS. As in a few of my other posts disconnect power from the tower and then from the motherboard to dissipate any residual charge, also take the battery off the mobi and use the CMOS jumper to reset the BIOS, you'd normally do this when you update the BIOS too. This will also remove any overclocking that may add to the systems instability. Just checked and it looks like the mobi supports the CPU: AM3 Phenom II X3 HDZ720WFK3DGI(BE) Heka 2800MHz 2000MH... x3 6MB C2 95W P1.10 Make sure you have BIOS P1.10 or above.

If you aren't going to do any form of OC, you should be just fine with a 750 watt PSU. But if you feel nervous, you can always upgrade it if the performance seem inadequate. As for the sound card, it would hardly use any power.

PSU with 750Watt its very power full PSU First you should see what Power your CPU need if you decided to not do Overclocking you will no need extra power Sound quality will be good if you don't take sound card it always good sound quality with your sound card that on board i think it will be enough 750Watts but if you afraid just buy more power full one and replace it but in my opinion its no necessary its all depend what you will do with computer if you some day decide do overclocking that you will need some extra power but antill then it no necessary

Ermmmm....this will come as no surprise, but you kinda lost me after the 5th word in your opening question!!!

What do I think????

I have no fecking idea - that's what I think!!!...lol

btw...wtf is overclocking??!!

I'll give you a star doc, even though you are my number 1 tech support /computer geek contact and I'm not so sure any of my other contacts will be able to help...but hey - you never know right??!

In the meantime, best of luck with ramming that mobo....and be extra careful not to overclock it too!

Oh my goodness!! All that technical talk is hurting my tiny tiny brain!

I think I need a Bex and a lie down... Lol!

:D

its sweet 750W is a good psu, if you started saying 4 hdd plus, then you might need more.

I must concur with Maz & Ange. I mean really, WTF???

@Maz-hi honey!!!

you can calculate your power supply here
