Dont do it! Its a POS that shouldnt be rated higher than 350W! Dont skimp on the PSU because you risk it going out with a bang. I would really suggest getting a high quality PSU like the corsair 550VX, a good PSU will last you many years

if you are tight on money you can get an OCZ ModXStream 500W PSU, still a good PSU and way more powerful than the one you are considering

The wattage on the label of the PSU doesnt mean much, always look at the combined amperage for the 12V rail as 80% of a modern system power is drawn from there.

I need one with 24A on the 12V rail with two PCI-E connectors, two sata, etc and i'm not spending $10000000 dollars on a PSU.

The reviews on the one I posted are generally good.

Logisys is one step above junk, and obsolete junk at that. This is an old design (look at the 3.3 and 5 volt rails) dressed up with some modern cables. A good 550 watt PSU should be able to produce 41 amps @ 12 volts. A 400 watt Corsair,
Corsair 400CX:

has more usable power.

 

[Disturbed205]

I asked for compatibility, thanks.

I just need something inexpensive, that has at least 450 watts and 24a on the 12V that will go in the computer I posted. I'm not interested in "future-proofing" or giving my computer room for expansion just a PSU that can run my GALAXY GeForce GTS 250 Graphics Card.

 

[hunter315]

Then the corsair 400CX that jsc linked to will be sufficient. We just dont want you to buy a POS PSU and have it take down your rig. Its significantly stronger than the 575W Logisys you linked to, and the 450W requirement that they put out is for PSUs that are rated like that logisys one, the 400CX will handle a GTS250 fine.

 

[Disturbed205]

It has to have two PCI-E connectors, that corsair does not.

Well, as you can see from the other posts the Logisys power supply is not a high quality power supply. It's quite apparent from the +12 volt rail rated at a mere 25 amps. That's one of the lowest numbers I have seen for what is supposed to be a 575 watt power supply. In addition, that psu has no PCI-e connectors for a video card. It is a low budget power supply of questionable performance and value.

I googled and could not find a competent techncial review of the psu. If you are referring to the customer comments at newegg, then it should be obvious it is a very low quality power supply. Almost 50% of the customer comments were in some way negative.

A high quality 500 to 550 watt power supply will have a +12 volt rail rated at 40 amps.

Corsair, PC Power & Cooling, and Seasonic are some of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units. An example would be the Antec Earthwatts series which is an improvement over Antec’s older series psu’s.

BTW - You do not need two PCI-e power cables. You can use a molex to PCI-e adapter available online for 2 or 3 dollars.

Well, I'm about to just give up and forget about it, I don't know jack about PSUs, I'm just trying to find something that has two PCI-E connectors to go into a GeForce GTS 250 Graphics Card.

It says it requires 450w PSU and 24a on the +12V rail.

I just want something that won't kill me/my pc and that won't cost me my life savings.

 

[Disturbed205]

What about this?


http://www.newegg.com/Product/Product.aspx?Item=N82E16817182199

Would it be compatible with my pc?

 

[Disturbed205]

...

 

[hunter315]

wow im impressed, an 80+ Bronze rosewill with decent power outputs. Yes it will be compatible, and 80+ means that it has been tested at 100% load so it wont explode either which is always comforting to know.

 

[Disturbed205]

Yeah, that didn't work out so great.
