Need a new PSU, how many watts?

[Koudelka]

Hello everyone.

I'm upgrading my computer. I decided its time since everything keeps crashing, although i believe it is my PSU that died after a year. I had an Enermax 12v 480w.

Anyhow.. this is what i will be running now.

AMD64 3500+(will be going for an x2 4800+ in the near future)
Evga 7800gtx
2gig corsair xms ram
160gb hd (possibly getting a 74gb raptor soon)
audigy 2 zs plat
dfi lanparty sli-dr mobo

Anyhow, what kind of PSU do you think i should get for this? I honestly dont know how many watts i'll need. But, i'm worried about getting another 480W and running into the same problem.

What PSU would you all suggest?


Thanks in advance!

fortron 450w for budget, otherwise: tagan 480 u22, seasonic s12 500w, or pcp&c 470w.

Well if you decide to sell that 480W of yours let me know. I'm still using my generic 400W which costs me $40.00 back in '98.

I wouldnt trust this PSU to sell to anyone.

Anybody else have any other suggestions for a PSU for me?

Yeah, I just junked my 460w Enermax. Went with Seasonic's, and I'm very happy with them. I'd recommend a Seasonic S-12 500w.

DFI-Street: Recommended! - NF4 Ultra/SLI MobosowerSupplies

Fortron AX500-A, if you don't plan on going SLI.

 

[Koudelka]

So a Seasonic s12 500w will work well with a DFI Lanparty SLI-DR mobo then?

I dont know enough about the whole 20/24pin molex connectors being quirky with mobo's from the threads i've read. I just know that there's a stickied topic on it, so i just want to be safe.

 

[KoolDrew]

The Seasonics are great PSUs (one of my favorites), but there are some issues with the DFI mobo. I don't know the exact issue, but you can probably check out DFI-Street and get an answer.

I don?t think I?m going to suggest a particular psu but I?ll ask, do you plan on upgrading or adding components in the near or far future? A nice heavy, beefy, name brand PSU would do nice. As many have said before, ?you get what you pay for.? Invest in a high quality unit and you $hould have it for year$. If you don't care about the warranty you can check out ebay; I've seen a few good ones sell for cheap.

Ok so I have a couple of questions:
The Fortron AX-500-A is only a 20 pin PSU, but comes with a 24 pin converter. Is there any draw back to that?
Also the Fortron has two 12V rails with 15 amps each but the Tagan 480 u22 has two 12V rails with 20 amps, I will assume that having more amps per rail is better?

 

[KoolDrew]

I will assume that having more amps per rail is better?

Yes, but you can't just go by what the manufacturer rates it as. Fortron is known for routinely exceeding their rated specificantions, while some other PSU's may not even be able to supply the rated amperage.

Yes you would be correct...I have that Tagan power supply, it works like a charm and it's a very very quiet PSU even on full load

 

[ECUHITMAN]

So I would assume that Tagan PSU would be powerfull and stable enough to run:

AMD 64 3800+ (evenually I would like to upgrade to an X2 core)
Abit AN8 SLi
BFG 6800 GT (evenually I would like to get another and run in SLi)
2 x 512 Kingston hyper-x DDR 400
WD 120 GB SATA HD

Even a quality 350w would be fine for it.

Hey, in regards to ?The Fortron AX-500-A is only a 20 pin PSU, but comes with a 24 pin converter. Is there any draw back to that?? The only drawback would be having an extra connector inside your case to hide. If you look at the slideshow on newegg, the converter is a harness that?s supplied as an extra.

Oh heck yes it would....
Mine powers a Epox 9PAJ Ultra mobo
3000+ venice @2.4
2X512mb OCZ Gold
7800GT
Samsung 200GB SATAII
plus a floppy, 6 case fans, and two optical drives

Ive had no problems with my X-Connect 500w. Its pretty and u dont have messy wires running everywhere. Just use what you need and put away the rest. My only dislike about it is that it generates alot of heat. But thats something i can live with,

So would my current PSU, which is a Thermal Take 420 Watt 20 Pin with 18 amps on the +12V rail be sufficient?

I like my Antec TrueControl 550, might be a little overkill wattage wise, but it has solid rails, long cables, and powers the beast in my sig. with no problems.
