Cheapest PSU there is

post #1 of 19
Thread Starter 
Okay, I'm planning on getting a opty 144, biostar TForce mATX, and, eventually, a 7800GT. Only problem is, after the opty and biostar, I have almost no money. Will a 300W 12V@15A even run the computer? If it can, then I can hold off the PSU until I have money and can get a good one. But I'm guessing my PSU can't handle it, so I'm going to need the cheapest possible PSU there is, but will give me enough power to OC and eventually hold up a 7800GT as well.

Cheap PSU + A Monsterous System = Does Not make a mix. Im guessing the cheapest PSU that you can get will be more than 80bucks.

This looks OK, but your going to need another PSU because this will definately not hold up SLI if you ever consider it.

This one is $85, but will run your system very well and is SLI certified. No, your power supply will not even boot your system. Also, remember that when a power supply blows, it usually takes several parts with it, so be careful.

Ugh, money....that I don't have. It doesn't help that I don't have a job either. I guess I might be waiting until I have money for a good PSU.

I'm not sure it will power all that, (7800 = power sucker) but my 450W ePower Puma II runs my system great, and it's got 28a on the 12v rail. It was $46.50 at NewEgg, they've got 500W+ PSUs for around $60.

$42

Rosewill 450W dual 12V PSU: I have the same mobo and a 3200+, 2 HDDs, and an X800XL. Runs it fine, lots of cords.

get it at the egg. SLI? I don't know about that.... why waste money on SLI anyway?

this is the cheapest I'd go
http://www.newegg.com/Product/Produc...82E16817104954
got one for my 2n'd rig... it's pretty good. 18a on each 12v rail

but you're much better off saving another 35 and getting a sunbeam nuuo. You don't want to use anything less w/ a 7800 series card. if you don't get a powerful psu you're going to have to choose
you can either oc or get a good gfx card... or neither, there are no guarantees w/ cheap psus.

I won't be running SLI because I have to use a mATX mobo, and when I really build a new rig, I'll just get a new PSU. For now, I just need something that will OC an opty 144 and eventually a 7800GT. Thanks for all the great suggestions, I'm comparing them now, and I'm open to any more.

This is a very good PSU for the price http://www.newegg.com/Product/Produc...82E16817148008

520W and 35A on the 12V rail. Its a very strong seller and I have never heard of one killing a computer. I have one myself and it works great.
