According to extreme psu calculator I need 753Watts to power my system :shocked:

X2 4400+ at 2640
EVGA 7900GTX 700 1800 sli
DFI Lanparty expert
2 one gig Patriot dimms
1 Raptor
1 maxtor ide drive
dvd-rw
cd-rw
Koolance watercooled (PC2)
Seasonic 600 S12

Hmmm. System seems to run fine with Seasonic.
You running EVERYTHING at once? CPU maxed out (multiple SuperPi instances if you can set them to idle priority), vid cards maxed out (game at max resolution /w highest IQ settings), optical drives reading/writing, HDs seeking, etc.? 🙂

That calculator considers the absolute worst case, and for HDs may even use the startup current, not seeking current.

I know this, I just thought is was amusing. It is getting scary though with the modern quadcores and quad video card setups that are coming. :laugh:
 
I was curious so I took a look at the fsp 700w ps and IMHO the amps are low on the 12v rails. An enermax liberty 620 has 22ax2 on the 12v rails. The pcpc 850 has 30a on the 12v3 rail for the graphics plus 16ax2 on the other two 12v rails. Amps are the key here so don't always look at the watt rating alone.

So your saying the Fortron may not be suffient?
Dont 12v rails use a combined power?

Because the Fortron has 4x 12v rails at 15v each.

I actually can get a V good deal on that.
I have a question though...

How badly would the PCPC Turbo 1KW SLI affect my electricity bill?
I mean, would it be a huge difference over my current 500w PSU?
I'm living with a bunch of mates next year and dont want to be the reason for excessive bills.
Since its efficiency is pretty high, it won't draw much power. However, PSUs with equal efficiency (equal all across the board) with a lower maximum power output will draw less from the socket because the average load will tend to be closer to the smaller PSUs most efficient supply range.


What I mean though, is will it be a difference of £10 a month, or £2-£3 (which I can live with). Bearing in mind, I have the high powered gaming rig, but my mates have laptops and 360's and we all have every other console.
So I'm assuming my 1kw PCPC PSU wont use up so much more power then an Xbox 360 and a 32" HDTV would? 🙁
You'd have to give me the cost of electricity for me to do the calculations... and I don't feel like doing them. So nyah. 😛

It's probably on the order of 2-3 pounds a month, if that. I'd have to know how much power your TV consumes to make a comparison.


Well an extra TV in the house only adds a couple of quid.
So I'm assuming it wont be too much.
I just dont want a PC chugging out microwave 1000w style power from my wall.
It might, depending on what kind of system you have. 😛

Actually, I don't think I could spec a consumer PC that used anywhere near that much.

quad sli anyone.
 
Ok guys.

Fortron FX700 Epsilon £95

Or PCPC 510 SLI £160

Which is the better buy?
I'm heading towards Fortron.

The FX700-GLN only outputs 600W when its intake air is 35 degrees C, whereas the PCP&C 510 maintains the rated power to 50 degrees C. The FX600-GLN maintains 600W through 35 degrees C and is cheaper than the FX700-GLN - however, if you have good case ventilation or a case with a bottom-mount PSU, you'll be able to get those extra amps from the FX700.

pcpc is undoubtly the best psu man. THe amps and rails are great. But, it is a bit on the loud side.

I'm worried 510w may not be enough.
I've read reviews from users of it on Newegg, with similar specs to mine who had had problems with PCPC running they're gear.
PCPC's responses were to simply buy the 850 version instead.

Anyone else want to one up that?

Enermax Liberty 620w is also an option

I myself won't be going with Enermax ever again. I'd go with the Fortron. I killed quite a few Enermax PSUs before I got to my current setup.

Woah! Not liking the sound of that!
Ok, Enermax ruled out again 😛

Out of the Fortron FX700w and the PCPC 510 SLI again.

They aren't bad PSUs, per se. I was just overpowering the hell out of it. Me, I absolutely prefer Seasonic now. Never had a problem with them, quiet as hell. I had just the 600w powering my system for a while on accident, and it gave me minimal issues. Then I fixed the wiring so that it wasn't carrying the entire load.

So in other words it was your own fault and I should consider Enermax?
Also, I really liked the idea of Seasnic, reviews are amazing.
But I've heard they have issues with DFI lanparty boards, plus, the dual rails only output 18a.
Is that enough? Considering the Enermax Liberty 620 has 24a per 12v rail.

Yes and no. Okay, here's the deal. I had about four Enermax PSUs, including two 480w, then a 550w, then a 660w EPS12V PSU powering most of this system. It had a few less hds, and they were all IDE instead of SATA. But it was pretty much that machine. I had issues all the way through the line of PSUs. My Seasonic 600w can handle the current system with minimal issues (I normally run two PSUs: a Seasonic 600w & 500w).

So the earlier 480w were being severly overpowered, but the 660 *should* have been able to handle the system, but there were still issues. So YMMV. Me, I won't be going to them again.
 
Check out OCZ PSUs as well, the 520W or the 600W if you're concerned. Got the 600W and its been great to me and very reliable and stable voltage on the rails. It should be more than enough for your system I would think. If you're willing to spend the money for a PCPC, then I'm guessing money isnt really an issue to you. And if you're willing to get a 700W, then overkill isnt either. The OCZs has nice rebates on newegg right now too.

I've read very good and very bad things about OCZ PSU's, so I'm steering clear.
Plus they are the same price as PCPC PSU's which on the grand scale of things, have a far better reputation and product.
