Would This be a PSU Problem?

[Marilyn1958]

I've recently started building my first PC, and have had some trouble with it. At first I thought the trouble was the motherboard, but now I think it may be the PSU at fault since when I plug in my keyboard, the backlights don't come on. Does this narrow it down?
(I have a better PSU and mobo on the way, I'm just curious at this point)
Current build
Biostar TA970 motherboard
Logisys 480w PSU
Zotac GeForce GTX 750 TI GPU
AMD FX 6300 CPU

Thanks in advance for any help.

Edit: I should clarify the problem was that the fans would start but I'd get no video

Yes, it looks like the PSU problem. I don't know which one 480W you had. http://www.logisyscomputer.com/products.asp?PID=200W&DID=POWERSUPPLY But they maybe same, the +12V rail has only 16Amp on it, and the gtx750ti requires 400W PSU with 20Amp on the +12V. So open the case to check the PSU. Also check out your new PSU too when you get it.

Sorry I didn't get the full specs, this was my PSU:

And here's my revised build http://pcpartpicker.com/user/Marilyn1958/saved/Lv2scf

It has the 16A on the +12 rail. http://images17.newegg.com/is/image/newegg/17-170-012-Z04?$S640$ You should get the Corsair cx430 at least.

With a Logisys power supply you will get nothing but problems.

REPLACE ASAP fire hazard.

As bad as Raidmax Supplies , which are probably the worst.

Yeah, I got the whole "logisys is fucking trash" thing as soon as I asked for some sort of help (What I should've done in the first place)

Corsair CX PSUs are also crap. Cheap design with cheap components. See This List (Link).

The CX is Tier 4:

Tier Four
Built down to a low price. Not exactly the most stable units ever created. Very basic safety circuitry or even thin gauge wiring used. Not for gaming rigs or overclocking systems of any kind. Avoid unless your budget dictates your choice.

Get an EVGA, Seasonic, Superflower, Seasonic or XFX from Tier 1 or Tier 2.

Cx430 is not the good one, but for the low power consumption computer ( 254W ), the PSU is good enough. And I will not recommend the cx series for the high performance pcs.
