is 450 watts PSU adequate to run: Gigabyte Mobo AM3+ DDR3 1333 760G; AMD FX 6300 CPU; Crucial 2 x 4 Gig Ram

jwilli · Oct 28, 2015

I have a Logisys 480 watt power supply @ 70% efficiency and I'd like to know if its sufficient to run the following:
Gigabyte Mobo AM3+ DDR3 1333 760G;
AMD FX 6300 CPU;
Crucial 2 x 4 Gig Ram
GeForce GT 640 128-bit DDR3
Thanks Jwil

clutchc · Oct 28, 2015

No gfx card? If not, then it will be OK. But Logisys is very low quality.

Thanks Clutchc,
I forgot to mention that my graphics card is a Geforce 640 2 gig, 128 bit DDR3. I am Not a gamer but I'd like decent graphics.

In that case, I'd need to know what the +12V rating of the PSU was. Either look at the nameplate or tell me the exact model of the Logisys PSU so I can check it out. The (DDR3) GT 640 will add another 65W to the load when it is maxed out. http://www.geforce.com/hardware/desktop-gpus/geforce-gt640/specifications

But I suspect you are probably still OK.

The PSU is: Logisys Corp. 480W 240-Pin Dual Fan 20+4 ATX Power Supply PS480D2

12v Rail specs: +3.3V@28A, +5V@36A, +12V@16A, -5V@0.5A, -12V@0.8A, +5VSB@2.0A

No, I wouldn't even try and do that unless I was heavily demented, the FX series processors are greedy buggers and they love power, if it was a seasonic power supply then it would be fine but that is not a good power supply run it if you want but I have a feeling you may regret it.

This appears to be your PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817170016
You will find Logisys PSUs in tier 5 of this listing: http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html#xtor=EPR-8886 ...the "Avoid!" section.
Likewise, this listing also puts them in the last tier, the "not recommended" tier: https://community.newegg.com/eggxpert/computer_hardware/f/135081/t/45344.aspx?Redirected=true
Can you run that system on that PSU? Maybe, the +12V rail is very weak and the protection is nil. Do I recommend you run that system on that PSU? No.

jwilli · Oct 29, 2015

OK thanks to all of you for your responses and I HEAR you load & clear!!
I already had the Logisys PSU but since I've reviewed the PSU "Tier" list I will order a 80 Bronze PSU.
Therefore based on my system below that I just purchased but haven't assembled, how many PSU WATTS do you recommend for:
Gigabyte Mobo AM3+ DDR3 1333 760G;
AMD FX 6300 CPU;
Crucial 2 x 4 Gig Ram
GeForce GT 640 128-bit DDR3

clutchc · Oct 29, 2015

jwilli :

If you buy a good quality PSU, you only need a 350W or greater unit for the 65W (DDR3) GT 640 and the 95W FX 6300. But if you intend on OC'ing the CPU or GPU, or you plan on upgrading the gfx card in the future, you will need more.

As you can see, it is not all about the total watts. There is more to picking a PSU than that. A good quality 350W unit will have a much stronger +12V rail with good protection than the cheap Logisys, so as not to fry the entire system when it dies.

This XFX 550W will allow you to run just about any size gfx card the FX-6300 can keep up with: http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013
And it is a top of the line unit.

Btw, is your PSU top mounted or bottom mounted?

jwilli · Oct 29, 2015

Thanks Grandmaster! I ordered the XFX 550 80 Bronze.
I may upgrade my gfx card later to a Geforce 750 Ti. Do you think the XFX 550 PSU will be adequate then?
My PSU is TOP mounted.

clutchc · Oct 29, 2015

jwilli :

Lol... the GTX 750 Ti actually uses less watts than the GT 640. http://www.hwcompare.com/17304/geforce-gt-640-ddr3-vs-geforce-gtx-750-ti/
That PSU will handle any gfx card the FX-6300 can keep up with. That would be the GTX 970.

Outlander_04 · Oct 30, 2015

You could easily run that on a good 400 watt psu , let alone a good 450 watt unit .

But the logicsys is junk .
The Corsair CX 430 is often very cheap . Buy one of those instead

Oli_The_Anarchist · Oct 30, 2015

The cx series is not a good unit it is tier 3 and from a company like corsair i would expect a lot better and you want something good to power an fx as they are very power hungry!

logainofhades · Oct 30, 2015

Actually the CX series have been bumped down to Tier 4. The best budget PSU's, for the money, are the XFX 550w's. They usually hang around The $50-$60 mark.

Outlander_04 · Oct 30, 2015

Oli_The_Anarchist :

I have used a few dozen CX 430's over the past ten years . None have failed in service .

Is it a high quality unit capable of sustaining high loads? Probably not . But it is adequate for this build .
And the OP seems to be buying largely based on price . At $26 the 430M is a major bargain

jwilli · Oct 31, 2015

Kudos to clutchc and grandmaster for the advice. I installed the XFX 550W and it's awesome and extremely quiet.

On another topic regarding windows and NEW mobos:

My system is now completely rebuilt. I Previously had a system with windows 7 "OEM" / SP-1 that I had upgraded to WINDOWS 10 about 45 days ago and I was worried about getting a new "valid" win 7 activation with the NEW mobo and cpu. So this is how things went:
1) I installed the OLD win 7 OEM on the NEW mobo.
2) During installation, a message said my win 7 was expired and it gave a message and phone# to CALL for validation of my OEM Win 7.
3) I called the # and got VOICE prompts that asked if i wanted to use my SMART PHONE or talk to a rep so I chose my PHONE and I immediately received a text message with step by step instructions.
4) I carefully followed ALL the instructions and was activated upon completion.
The whole process took 10 minutes.
In summary, YES you can activate a NEW mobo if you have a valid OEM /SP-1 version of windows 7 even AFTER having installed windows 10 beyond 30 days.
