Enermax Liberty 500w PSU - Powerful enough?

[Daze]

Is my trusty Enermax Liberty 500w PSU powerful enough to power this kit:

Antec Nine Hundred Case

Intel E6600 CPU

2Gb OCZ SLI (1066) DDR2 RAM

EVGA NF680i Motherboard

Sapphire ATI X1900XT 512Mb Video Card

Soundblaster X-Fi Sound Card

2 x SATA HD

1 x Sony DVD+RW (Dual Layer)

I can't really afford to shell out on a new one, but I've a feeling I might be asking a bit much of it.

Hmm I reckon if you should be ok tbh mate

Yup you're fine.

That rig @ stock will draw about 300w from the outlet peak.

Thanks guys - You've put my mind at ease...

Hehe np.

With the CPU @ say 3.5GHz 1.45v, and the VGA @ 700/800 (various voltages), you might pull 400-435w PEAK from the wall. You'll be set for a while. It'll handle an 8800GTS 640MB too, FYI.

People have a tendency to.. hm, "over buy" when choosing a PSU.

"LOL GOT GTX? 1kw FOR YUO!"

Is their potential damage if lets say daze used up all his power if he raised CPU/chipset voltage or would the system just not work alltogether?

 

[NickS]

The PSU would trip (shut off) from OCP (over current protection).

Most if not all high quality units have this system implemented so the PSU will cut out before damage occurs. See my sig, and clocks? I've done that on a TT TR2 430w rock solid stable for 2.5 weeks while my Liberty was getting RMA'ed from a fan dieing. Rigs don't draw as much power as people think.

how can i tell how many watts my PC is drawing? I've been only going off based on an online calculator.

Buy something called a Kill-A-Watt

Note that it will tell you how much your PSU is drawing from the wall, which is different from your components total, but it'll give you a rough estimation. This is because PSU's aren't 100% efficient, so they draw more power than they "need."

You should be fine. I'm using a 480w PSU for my system.
