[Solved]Enough power?

post #1 of 4
Thread Starter 
I currently have a lot of stuff powered on a 750 watt power supply.

A stock i5 2500k.
An H100 cooler.
An ASUS Maximus IV P67
Four 1.5V DDR3 RAM Dimms
One SSD.
One HDD.
Five 120mm fans.
Two crossfire 6950's, 2GB.
A controller for the fans.
A front-bay SD card reader
A CD/DVD Drive
And about 5 USB devices.

I'm pretty sure all together that has got to be around 650 watts.

The processor draws, what is it, 95 watts?
"Speccy" by Piriform says the max power draw for each of my 6950's is 200 watts.
The fans all together are a little less than 20 watts.
The H100 pump might pull 10?
The two drives together are maybe 10 watts.
I'm not entirely sure how much my USB devices draw, but it can't be too much all together. Maybe 15 watts.
The CD/DVD drive doesn't draw much, maybe 8-10ish.
And the front bay panel takes none until a card is inserted, correct? And even then, very miniscule.
Add on the motherboard wattage and what not.

This seems to be about right, as those "power supply calculators" say it's about the same. A little more, but some of my components use less power than the ones rated in their calculator. (IE their 120mm fans are 5 watts per, mine are roughly 3.5 per.)

I highly doubt it will draw much more than 20 watts, but was wondering on what the ASUStek Xonar Essence STX draws for power. I can't find any information online about it. Also, does OCN think 750 watts for an over-all 670ish is enough head room? The power supply is a Corsair AX750. One of their best power supplies.

You'll be fine, I'll be running a similar version of your setup here very soon (but overclocked) and I have no doubt my TX750 will handle it just fine. You will be fine.

God no, you must get the new 1500w evga right away. But seriously, your rig draws nowhere near 650w. 500w actual draw would be about max with furmark and prime running concurrently. Your cpu is a 65w part, 95w would be only with an oc.

I actually previously had a 750 TXV2. Corsair gave me a replacement after it failed, with an AX750.
It's a long story as to why it failed, but it's a great power supply. It should have failed sooner.
It had been through two power surges (one when I wasn't home, one during a hurricane). It also had been through a house fire. The unit itself wasn't in the fire, but the damage from the smoke made pretty much everything in the house have to be replaced. The computer, and power supply unit, was one of the only things "spared" from the fire. To go through a motherboard short, two years, and two surges. You'll be very pleased with the resiliency of these units. As I said, it took some abuse, and I was surprised it managed so long.

I figured 650 would be very high end draw. I believe my 6950's clock up to 6970 on load. But that might not be entirely true.

But thanks fro the input guys!
