PSU

[AliasX]

I have pretty much everything hooked up. This is my first build, and there are these slittle cords with white ends which are really tiny, and I haven't plugged those into anything. Also, there are some internal speaker cords to hook up that I haven't hooked up. I have a 7800GT which has the optional 6pin PSU hookup. Of course I want to have all the power it needs getting to it, so I want to hook it up. My problem is that my PSU, which is a generic, but I want to use it, doesn't have any 6 pin connectors. Can someone help me? or do I have to get a new PSU.

The card should have come with a molex to 6 pin adapter

Here ya go. Why do you have a 7800GT video card and a generic PSU though? TSK TSK TSK

 

[ShellGuy]

I woudln't even power that thing up with a generic PSU in it. As you are askin 4 trouble. Do you happen to know what the wattage is and if it will push ur whole system?

420 watts.

The worst that could happen is it doesn't boot up, or it crashes. I highly doubt my parts will get broken.

You parts can get broken and there is a high chance that they will. Generic PSU's are unstable, they can provide too much voltage to certain parts and fry them. Believe me, I know. I lost 160GB of stuff cause I had a generic PSU for a while and it fried my hard drive. You're asking for trouble if you try to boot that thing up. If you push the power button and you didn't get lucky, then boom, your new computer is gone.

EDIT: Why the heck are you using 3 80mm case fans? what kind of case do you have? lemme guess, generic?

What's the worst that can happen? Oh dear.... A lot worse than that. Dead hard drives, components ruined...

Power supplies have got to be the oldest computer part, and one of the most common ones. How can a company build a friggen PSU the wrong way?

I have only heard of computers not booting up, and fried mobos.

wow, I thought everyone knows this stuff, especially people that are building their own computers. Be very careful or else you could kill everything.

EDIT: Fried mobos are VERY common when you don't have a good PSU. With that much money on the line, I wouldn't risk it.

EDIT2: Look at this

I will post the stats on the side of the PSU:

DC Output/ Current - 10A/5A
+3.3V - 26.0A
+5V - 32.0A
+12V - 13.0A
-5V - 0.5A
-12V - 0.8A
+5Vsb - 2.0A
Total Output Wattage - 420W
That was all on a sticker on the side of the PSU

Edit, I could google Computers run over by a llama and get just as many results. There are problems with every computer part, and that is all you hear about. You never see success stories. I doubt anyone has posted 120W PSU powering Monster rig, but someone probably is running a monster rig with a 120W psu.

HAHAHAHAH I highly doubt anyone is running a monster rig with a 120W PSU. Now lemme look over this.


DC Output/ Current - 10A/5A
+3.3V - 26.0A (a little low)
+5V - 32.0A (not bad)
+12V - 13.0A (Holy Crap ARE YOU OUT OF YOUR MIND?!?!?!?!?!? My psu has 44A on this rail. I WOULD NOT TOUTCH THIS PSU WITH A 10 FOOT POLE!!)
-5V - 0.5A (seems sorta low)
-12V - 0.8A (ok)
+5Vsb - 2.0A (low)
Total Output Wattage - 420W (For a rig like this, I would reccomend 500 from a GOOD brand, 420 generic is not nearly enough)

EDIT: Dude, you sound like you are trying to convince yourself that you are okay, but in all honesty, let me tell you that you are NOT. If you turn on your computer and it fries (might not be right away, could be a few months down the road), then don't go blaming us that we didn't warn you.

EDIT2: P.S., the 12V rail is THE most important rail in the PSU.

Thank you for all of your help, but I feel like taking the chance. If it blows, you will see me weeping, but I have taken into consideration all of your warnings.

Really, I don't feel like blowing $100 on a PSU, and I want to run my computer today!!!

You don't feel like blowing just $100 on a PSU to make sure that your computer won't die? Here are your options.

1. run computer now, risk killing it

2. run computer in about a week, have it last for the next 5-10+ years.

Then blow $50 on a frotron 400W.

Assuming that PSU can even supply it's rated wattage it'll be lucky to power your system. Look at the pathetic supply to the 12v rail.

You can't run your computer today as you don't have the power cable that the 7800GT needs. Live with it.

QFT. I forgot how cheap the fortron's were.

 

[AliasX]

I did find the power connector cables for the 7800GT

http://www.newegg.com/Product/Product.asp?Item=N82E16817104954
would that run my system? with 2 cold cathodes lol?

That would be excellent.

OP, ppl aren't lying to you. The system may boot and work for awhile but once under load with the PSU warm...It will happen, sooner than later.

Every week there will be three or four posts here about hardware damage from unstable voltage. Best of luck to you.

Crescent, the EnerMax Liberty 500 is highly rated and deservedly so, but combined 12V is 32A not 44A. Each 12V rail will deliver 22A but combined never exceeds 32A.
My Zippy/Emacs HG-2 6400P(400watt) has 12V@30A@40C. One 12V rail.

...Galvanized

 

[AliasX]

Those also cost upwards of $100.

If you wanna give me some money, I will get it.

The 400W fortron would be enough, the 450W is overkill, but it's not massivly more expensive so why not.

EDIT: OP, he was just telling me that because that's what I have.
