would i need to upgrade my PSU?

okay i made a thread about my h70 just recently, but i got to thinking, am i selling my system short with the PSU i have? im running 4 HD's, 2 DVD drives, 5 fans, a R5770 and my Phenom II x4

i have a corsair 400watt PSU, ive had this thing for close to almost 2 years. still running like a champ, never had a problem but i somehow feel im hurting my system by having such a low wattage PSU, with PSU's having 80 gold and so forth as the standard now. i dont know anything different, but would this make a dramatic effect on my system as far as pulling resources from the supply itself? i do game, i dont notice any lag in my system, what would be your recommendation? i was thinking about upping to 750watt corsair

To be honest I am surprised you haven't fried your 5770. My co worker fried his video card with a low watage PSU, as it wasnt pushing enough to power the fan fully.

Wow that is a low powered PSU for the setup. In your configuration you are probably maxing out your PSU. An upgrade to 750W will give you a bit of headroom and if your system is calling for max power, the PSU will only be at 50%-60% which is what you want to avoid overworking the PSU and under powering your graphics, CPU, RAM, etc.

yea, the 5770 handles the PSU like no problem, i never had a problem in game, when im running fraps im still avg 60 FPS in most games.

the fans on my 5770 run great, never had a problem, when i play games they both increase to over 2000 rpm, so its getting the power. im pretty sure ima get a new modular, just wanted a second opinion

Thats often the difference between a quality power supply and a crappy power supply. The corsair is putting out an honest to goodness 400 watts of power. And this thread goes to show that PSU, can stretch farther than a lot of people think.

Your Corsair power supply is a very good one, you are just working it very hard. That creates heat and shortens it's life. A Corsair 750 or 850 would do just great plus give you a little head room for other things down the road.

750 is way overkill, but if you want to spend the money for it, do it.
I personally wouldn't upgrade the PSU right now unless there was a very good deal on one, otherwise I would wait till I upgraded the system or the PSU fails.

I am running an Antec 650 in my current setup, and in my old setup I had more than double your hard drives (9), Intel C2Q cpu that was overclocked, had 4 sticks of DDR2 1066 ram, and a GTX285 and 9600GT video cards, on the same 650watt PSU.

yea absolutely i agree, when i bought this PSU i threw it in the dell dual core i had cause the PSU on that blew out, did my research and it led me to Corsair, ill probably keep it as a back up or if i build a browser computer cause its legit and i leave it running 24-7 and never had a hiccup. i was on newegg and i was looking at PSU's

any recommendations besides corsair

I've been running Antec PSU's in all of my personal builds and machines I build that have higher than $450 budgets.

I haven't had one fail on me yet, but I did have one that developed a loud coil whine. Antec replaced it for me, just had to pay to ship it to California.

Be sure to look at Seasonic.
Seasonic makes most of Corsair's and many of Antec's power supplies.
