is the corsair 620w future proof?

ive got the modular corsair 620w psu now. i just upgraded from dual to quadcore. given my system specs, how much more can i add before this isnt enough?

Q9450 overlclocked to 3.2
Gigabyte EP45-DS3R
4gb (2x2gb) corsair pc800
nvidia 8800gtx (cant believe im still running this thing. best $600 spent)
x-fi platinum with front iodrive
2 sata dvd-rw
1tb western digital caviar black
tuniq tower (120mm fan)
antec p182 4x120mm fans

i just dropped the 9450 and mobo in this weekend. the tuniq and wd black hdd will be added today once ups drops them off. i overclocked the 9450 last night and got it running prime stable. still at default voltages too save for ram which is 1.9. more oc will draw more power but im happy for the moment. i think im good psu-wise for now. but lets say i want to toss in a newer vid card. will it still be enough? gtx280 or equivalent ati for example. dont plan on sli though the mobo supports crossfire...

 
I would go ahead and get a little bit bigger one if you were buying new, but I'd just keep the 620W probably until they go to 10-pin PCI-e 🙂
 
Considering it has 50A total 12V rail continuous it should be more than capable for a while. That's why I got mine when I did last year :thumbsup:
Q6600 @ 3.45GHz 1.45V and a X1950XT. I'm planning on going to a 4870 in the semi-near future and I have no doubt it'll be capable. Not sure if it could do crossfire of 2 of them, I'd have to do the math (too lazy to) but I don't intend to have 2 GPUs.. then the 4870x2 may be tempting too if it is released before I upgrade....

LOL....we'll just make a new cable. Ahhh....the beauty of modular!

This question has gotten asked a lot on the Corsair forums and Corsair has responded that the HX620 can do 4870 Crossfire just fine.

When you use the 620HX remember to keep an eye out on the 3.3V and 5V power rail.

GPUs still use power from 3.3V and 5V power rail, your motherboard, HDs, Opticals and others like USB devices also do.

If the the 3.3V and 5V power rail became marginal for your power draw the first thing likely to die is your mobo, following by others. PSU usually is the last thing to go.

Unfortunately, not if you're running my rig it can't. That's why I had to upgrade to the HX1000.

Honestly, I think even for the "average power user" a HX620 is not enough for dual HD4870s. Each 4870 pulls about 150 watts each, right? That's 300 watts right there. Add in the MB, CPU, HDs, USB device, etc and you would probably be running up against the limit of the PS.

Don't know about you guys, but I don't want to test the limits of the HX620 by possibly letting The Magic Smoke out of it and all the other parts of my PC. :Q
 
Mine runs fine though.

Asus Rampage Formula
Intel Q6600 @ 3.2 GHz
4x 2GB G.Skill 1066 RAM
EVGA GTX 280 FTW (BIOS overclock)
1x Raptor 150GB
1x Seagate 320 GB
1x Seagate 500 GB
1x Samsung 750 GB
1x Samsung 1TB

Idle while using this PSU is around 150-180~W depending on how many HD is active at the time. Load (in games or 3D Mark) is around 298-314W

beray has done nothing but post about the Corsairs not handling crossloading of the 3.3V and 5V rails too well, but has done nothing to substantiate his claims or provide a better alternative.

Since the vast majority of desktop rigs (dare I say 99+%?) will not run into such a crossloading issue, crossloading is irrelevant.

<-- very satisfied new Corsair TX650 owner.

You don't use that much from the 3.3V or 5V rails anymore, but even if he did he has nothing to worry about because it doesn't go wacky

 
Yeah, from what I've seen, the consumption is quite microscopic compared to the pull from the 12V. GPUs are pretty much 12V and that's it.
