Enough power?

[Vaio]

I am wondering if my current power supply is capable of handling the load of my soon to be upgraded system. It is a Corsair 620HX. It will be powering:

Q9550 @ 3.4+
Asus P5E Deluxe
8gb DDR2
4870 x2
2x 160gb raptors
74gb raptor
400gb seagate
dvd-rw
MCP-655
6 Sanyo-Denki fans
CCFL lights and random other small things

I know I'm probably pushing it, but I'd like to avoid upgrading if possible.


Thanks for helping :)

That 4870x2 will be the most power hungry device followed by the raptor. If you plan on running stock speed, then it might handle it, but if you're going to oc, that 620 will be maxed out.

Definitely overclocking the x2 :D

Guess I might need to find something that'll handle it all. Would a PC P&C 750 or a Corsair 750 be enough for it all?

Either one will give you the cushion you need.

Indeed ;)

Before you spend the big bucks, try the HX620 first and see if you experience any problems. :)

The raptor at spinup certainly isnt the 2nd most power hungry either. I mean heck, an overclocked quad vs raptor in power usage is like putting your tounge on a 9v battery vs sticking in an electric socket in my opinion.

My rig uses 460W from the wall (cpu with P95 small FFT @ clocks in sig, GPU @ clocks in sig with furmark, HDD run HD tach), add another 100W for the dual vid card and thats 560W. Then you have to think of the efficiency of the PSU and you can determine that your system probably wont even sniff 525W with the CPU and GPU in full load. Not to mention the HX620 was notoriously underrated, or rated right depending on who you talk to. 40A would power that PC, the 620 has 50A continuous available. Granted, I wouldnt put much more than that on there, but its well within spec to do so.

EDIT: Everything you see in the sig is powered by the 620HX. Oh and dont forget to add 8 120mm fans + 200mm fan and a cold cathode black light.

[Vaio]

I like that thinking. If all else fails, I can run to a local shop and grab a better psu :)

[EarthDog]

You will be fine with that I would bet good money on it.

The problem here is not whether it is capable on paper, it is. Some time ago Corsair released a recommendation not to use the HX620 on 8800GTX's SLI when they first came out. They recommended their 750w model. The 4870's SLI are about the same as 8800GTX's SLI, perhaps a little more. When the manufacturer doesn't recommend one their own models, a prudent user should take that advice. It couldn't have been a sales pitch because the HX620 cost more than the VX750 and still does.

I think Oklahoma Wolf reinforced the Corsair recommendation some time ago.

Now if a person is on a budget and has a good power supply like the HX620, then by all means try it and use it but a single 260 does not equal a 4870X2 or 8800GTX's SLI.

[wingman99]

All you have to do is try it. Corsair is a good PSU it wont let you down it will not start up or it will shut down if you overload it.


I just got a SeaSonic S12 II SS-330GB 330W today to replace one of my old PSU it was a 500w FSP, it was getting old and was hard starting, I'm now running a GA-P35-DS3L MB, Core2Quad, 2GB of RAM, OC 8800GT video card, 1 raptor 150G and 1 samsung 500G hard drive , and 2 DVD's off this 330W PSU with no problems 5 year warranty, full load it draws about 300w i figure.


I have a 620HX and corsair in my main rig and they sent me 2 cables with 4 PCi-e connectors to run any SLI or Crossfire 6+8 dual plug cards that i want and we still get the 5 year warranty.

When you buy a high performance PSU run it to the max, that's what i do with all my good equipment that i have, that's wat good equipment is for, I don't buy a 1000cc yamaha R1 motorcycle and only run it up to 80%

Pleas if anyone can find something saying from corsair not to use the advertized 620w pleas post.

QUOTE:
In our internal testing, we've identified that at full load, an 8800GTX consumes around 160-170W of power from the +12V rail. This is about 14A.

Two of them total to 28A.

The rest of the hardware is dependent upon your configuration, but an Intel Quad-Core processor (QX6700) overclocked to 3.3 GHz on an eVGA 680i motherboard draws about 11A from the +12V rail. So now we're at 39A.

Add a couple hard drives at 1A each, you're between 40-45A on the +12V rail at your ambient case temperature (which is most frequently between 35C and 40C) and our HX620 can handle 50A on the +12V at 50C, even more down at 35C and 40C.

If you have some huge number of hard drives, like more than 6, you might want to look into a higher-wattage supply. Keep in mind, it's not running at those ratings at idle.

At idle, the G80 draws about 7A, or 84W of power. The processor draws 4A, or 48W of power. The same system above that draws ~45A at full load will probably draw less than 20A at idle.


corsair says 620 continuess watts why waste it give it a try.:beer:

google 4870 x2 power consumption
http://www.pcstats.com/articleview.cfm?articleid=2304&page=3

found this website, very handy information to know. ok so based on the charts your 620watt should run your components just fine. If you decide to add another card later (I don't know if you mobo has 2 pci-e slots or not) you will need a bigger power supply, at least 750watt.

you'll know when you fired it up and run it under load if its stable, should be fine as is.

Here is the same reviewer with the same setup (Q6600/X48) with just one HD4870x2. 524W. That same reviewer did CrossfireX with 4870x2's on that same rig and pulled 739W from the wall.

If you take a peek back at my post, I said to "add another 100W". As you can see by the link I provided, looks like I was pretty close. ;)

That HX620 will be just fine. :beer:

No, but you did state:

EDIT: Everything you see in the sig is powered by the 620HX. Oh and dont forget to add 8 120mm fans + 200mm fan and a cold cathode black light.

Your setup is using less of a power draw with that 260, so what RT stated is true.

[EarthDog]

Jesus....... I guess. That was my next statement. I assumed (my bad) he was referencing that initial paragraph. It was just a reference point as I also gave those wattage numbers in the prior paragraph as well.

I still never stated, nor infered a 260 was = 4870x2. It was just supporting my wattage example for my PC in the paragraph above (where I said 460W). Which is where the "add another 100W statement came from.......ya'll following my vague post now people? :)

Here let me Cliff note that bad boy for you all for clarity.

My rig uses 460W from the wall (cpu with P95 small FFT @ clocks in sig, GPU @ clocks in sig with furmark, HDD run HD tach), add another 100W for the dual vid card and thats 560W.

[Vaio]

I really appreciate all the responses. Rather than let this arguing continue about little details that are mostly irrelevant, lets just all get along, and see if my PSU blows up when I turn everything on :D

[EarthDog]

People discussing semantics will get ya all the time. It was my fault I was vague. I wasnt trying to start anything, but just clearing the air. Im not sure the need for the other post to point out what RT was saying though and what he said was "true", I knew what he was talking about, but he missed the association of my edit, but oh well. Thats a forum for you. :)

[Nebulous]

Us argue? nahhhhh, we just have "differences" is all ;)

I'm sure Viao will make the choice he can live with for his particular setup :D

[EarthDog]

Notice I said discuss? roflmao!

Carry on guys. Sorry about the OT jacking Vaio, use that 620 buddy!!!!

Cal,

You're correct, misinterpreted on my part and my apologies.

My point was not whether the HX620 would run it all because we know it will. The recommendation statement from Corsair was relayed on this forum some time ago and the details are unknown. I don't know the tech details but one can only assume Corsair did not recommend running their unit continually at a high precentage of output but I'm only guessing here.

[Vaio]

Don't worry about it. I just felt bad that my question led to such an energetic "discussion" ;)

[RollingThunder]

Vaio,

It's all cool. These guys are all very capable and knowledgable and I respect their opinions. To reinforce my side of it, I agree to try it and run it. You won't hurt anything because your Corsair is a top notch unit. However, if you feel you need more, the VX750 can always be found at an inexpensive price.
