Which PSU with this setup?

.:dhry:. SiroVa · 8 Nov 2006 at 08:04

E6400
Gigabyte DS4 or Abit AW9-D (Havent decided yet)
2x1gig Corsair 6400 C5 (twinx)
Connect 3D 256mb x1900 XT

WD Raptor 150 x 2 in Raid 0
DVD/CD-RW
Maxtor Diamond Max IDE HD - 200gig - backups
Razer diamond back mouse
Webcam
USB printer
USB router

I will be getting DX10 cards in CrossFire Format when they come out for ATI. Thats why I'm getting an average card now. So the PSU would have to be able to cope with CF when it comes to it.

Heres some ive had my eye on as they support ATI CF on their spec, if someone can give me some reccommendations, thanks.

Hiper HPU-4M730 Type R 730W ATX2.2 PSU
FSP Sparkle FX700-GLN Epsilon 700W ATX2.0
Corsair HX 620W ATX2.2 Modular SLI Compliant PSU
Seasonic M12 Modular 700W Silent ATX2.0 - most expensive, really worth it?

Have you thought about an Enermax Liberty 620?

Supports crossfire and gets some top notch reviews.

interesting , I just put your spec to a calculator under 100% cpu ultization and for a xfire setup...

heres the resuly

I also added 2 pci cards and 1 firewire card...

i got a result of 1473w

wow.......surely that cant be right....

I would get the gigabyte board opposed to the abit as abit boards with conroes are picky with the type of RAM used...

You must be made of money to be able to purchase a x1900 for temporary use...

650 Watt Antec Trio. 57 Amps.

It's the only way forward.

I'm slightly curious how you managed that, :confused:

I put in the same system as .:dhry:. SiroVa specified and even allowing an overclock to 3.4ghz with 1.5v vcore, the Crossfired setup and I put the Raptors in as 10k SCSI drives also but even then it still only comes in at less than 530w.

I'd probably pick the Corsair(basically the same as the Seasonic M12 but cheaper) or the Enermax, either will be more than capable.

yes me too, ive never seen a system come out at 1437w EVER EVER lol

The Enmermax 620 Watt is 80% energy efficient, has 22 amps on each of the two +12v rails (44 amps in total) and costs £105.74 inc VAT.

The Antec Trio 650 Watt is 85 % energy efficent, has 19 amps on each of the three +12v rails (57 amps in total) and costs £91.64 inc VAT.

edit: Now I'm confused. going from the Enermax site it looks like 44 amps, but reviews are showing 36 in total?

Smashin,

Thanks for all the suggestions.

Combined rails never give the equivalent of the independent rails so 2x22A giving 36A is probably right, likewise the Antec won't give 57A, it is probably more like 45A(at a guess), there is probably some mathematical formula to determine it but I don't have a clue what it is.

Rails are not additive. You have to look at the maximum combined output wattage. For example, on the Antec Trio 650W spec, it says "+12V1, 12V2,12V3 maximum output 624 Watts max". You then divide the wattage by the 12 (for +12V) to give you the amps, which in this case is 52A.

Antec Trio has better features than Enermax Liberty, but it is a lowend design from Seasonic. The highend designs from Seasonic are their M12 and Corsair HX Series.

Oooh ok, now I get it. Adding the rails just seemed to make sense.

Not that much in it though in fairness.

Lowend design you say?

With respect to reviews, I'd suggest some research from reviewers that thoroughly investigate PSUs. Too many reviewers simply recieve a PSU, plug it into a MOBO, declare that it is great simply because it does not catch fire, then give it some award.

For example, JonnyGuru properly reviews a PSU. He HEAVILY taxes a PSU and is more thorough than most. He uses excellent methodology and tests a variety of things many reviewers skip such as ripple, output at excessive temperatures, capacitor and PCB layout, etc.

As far as this thread goes, he has an excellent PSU review of both our HX520 and HX620. They perform better than any PSU listed so far in this thread.

Corsair PSU Links

From what I have seen at OCUK and others, the prices are very competitive and our PSUs outperform ANY PSU in its class.

For what it is worth, we have an HX620 in our lab right now running 2 8800 GTX cards in SLI along with the rest of the system, solid as a rock.

That's a very good site. Found the Antec Trio review very interesting, especially the fact that he pulled it apart to really see what was going on. He proved it couldn't pull off the amps it was rated for, but in all fairness it was close enough not to matter. I only got the thing 'cause I knew it was high.

I still recommend it though.

.

Point well made. The Hiper series of bling PSUs got rave reviews from many of these these self appointed online reviewers. I was one of the many who should have known better and bought one of these toytown PSUs. Fortunately mine only lasted half an hour so I was able to return it for an immediate refund.
