I am upgrading the rig in my sig was thinking about putting in a 5850 and a q6600 with a decent OC and maybe some faster ram. I currently have the PSU unit in my sig and was wondering if anyone thinks it wont be enough? I also have 1 dvd burner and 2 hdd in there right now.
 
Hi! I'm the one who PMed you about selling my Q6600. The spec I had when I OCed same Q6600 were OCZ 500w PSU, GTX260, 1 HDD and 4 sticks of ram so I don't see why not with your PSU. Also, I'm in process of selling fast 2x2GB RAM too if you are interested. Let me know if you are interested and I'l PM you the deal.

Thanks

how many amps on your 12v rail? i see the 18 + 18 but that doesnt mean you have 36. you get the total watts in your 12v rail and divide by 12 thats give you your amps.

w/your card stock under load you draw 199 watts and a Q6600 GO @ 3.33ghz you draw 259 watts. add those thats 458 watts. you still have to add hd, dvd drive overclocking the gpu, ram putting you q6600 to 3.6ish. you get the picture. get another power supply. id go with 650/750 to play it safe

WTF? Try looking up Ohms Law (W=V x I). If there's a total of 36 amps on the +12, then there's 36 amps. The wattage would be 36a x 12v, 432w for the 12v.

He means that the sum of all the +12V rails' individual OCP limits is not necessarily equal to the total rated current on all the rails combined.
 
With a brand new decent (well reviewed + high power on 12V) 500W it will be fine but I wouldnt do it as PSUs dont remain new.
Yours isnt new so it will have aged meaning maximum power output has dropped and will drop further.
Get a good 600 to 700W for peace of mind.

If the PSU isnt strong enough, it may just result in crashes or shutdowns.
There are many other modes of failure though such as extra noise on voltage rails (extra heat and other issues), through varying voltages to catastrophic failure of the PSU. Any one of these can damage things connected to the PSU.

My sig rig has been running on a 430 watt for over a year now.

Its not exactly high power kit you have and whether its a high risk or not after a year depends which 430W PSU you have.
How long you intend to use it can be crucial too.


Most PSUs use electrolytic capacitors which age fast, this basic lists demonstrates.
http://my.execpc.com/~endlr/aging.html

Take a look at the Antec PSU calculator.
http://www.antec.outervision.com/
It includes capacitor aging
4 Electrolytic capacitor aging. When used heavily or over an extended period of time (1+ years) a PSU will slowly lose some of its initial wattage capacity. We recommend you add 20% if you plan to keep your PSU for more than 1 year, or 25-30% for 24/7 usage and 1+ years.

Feeling lucky? ;)
 
It's not a high power setup, you're right. But this PSU brand is AGI, and AFAIK, it's not really a big name company. I really do need a new one though. That's a lot of good information you gave there though.
 
Using the following:

Desktop motherboard
Q6600
100% TDP
Overclocked to 3.5GHz @ 1.35V (you need to check this with your chip)
4 sticks of DDR2
2HDDs
1DVD WR
3x120mm fan (assumed, dont know how many you have)
100% peak load
30% capacitor aging.

This came out to 571W.

There's no way to know that's what he meant when he posted the following gibberish:

you get the total watts in your 12v rail and divide by 12 thats give you your amps.

I know that English is the second language for many folks on boards, but if you can't get Ohm's Law straight in a PS forum don't bother posting.

Uh, this is the OP's setup:
Intel E5200 @ 2.8, 1066 FSB
Gigabyte GA-EP31-DS3L
4x1 GB Crucial DDR2-667
VisionTek Radeon HD 4850 512mb DDR3 (675/2190)
Silverstone ST-50F 500W

If that system drew more than 200w, I'd buy him a new PS.
