Antec 1kw PSU.

[daza]

Right after chucking in my upgrades for this year (X38 Quad gt and a second 8800gts for sli) plus my overclocked Q6600 it doesn't look like my 730w hiper psu is going to be able to cut it (+5v rail is already at +4.98v).

So after being told that I would require near 900w I had a look around and stumbled across the antec truepower Quattro 1000 so whats everyones thoughts. Its little brother the 850w version looks to be getting some good reviews as well just cant find any for the 1000w version, plus it looks to retail for around £140 as well which isn't to bad I think.

And if theres better out there for the same price(ish) suggestions would be welcomed.

How do you know that the "+5v rail is already at +4.98v"? Do you have one of those little amp metre thingies or something?

[daza]

I use everest to monitor the sensors as well as uGuru to double check.

[staffsMike]

How about the enermax galaxy.. supposed to be quite good

dont trust those programs for monitor readings! if you want accurate use a multimeter. 4.98v is nothng to worry about anyway!

[acrobat]

Yeah, "multimetre". Thats what I meant by "one of those little amp metre thingies"

As for Everest, I didn't realise that told you what power is being drawn. It is quite reliable for temperatures and most other info, but I couldn't say whether its reliable for amps/volts etc.

Anyway, try this, incase you haven't already:

That should give you a pretty accurate idea of how much power you will need. An overclocked Quad core and two 8800GTS's... is gunna use a fair bit of power. But whether it would actually need more than a 730W PSU, would be worth checking. The GTS's aren't any way near as power hungry as the GTX's. So you might be ok.

But if you did upgrade, a 1000W would be a good idea. Nice and future proof. I can't help you with that brand though The 850W gets good reviews, but thats no indication of the 1000W. Google is great for these things though. If you struggle getting a good answer about that specific PSU, you should be able to find plenty of decent "1000W PSU reviews" on google, if nobody here knows any good ones.

Everest is a bit pants for some voltages on some boards, it shows the 12v line on my Galaxy to be 8.xx volts, yet everything else shows it as 12.xx.

The PSU Calculator gives about 710W for everything. And that calculator is quite over-estimated (so that people don't try to overload the PSU). The fact that 710W is the worse case scenario, your 730W will easily handle it.

If it doesn't (highly unlikely), buy the 300W FSP PSU that fits in the 5.25" bay for extra juice.

4.98V is normal for 5V rail. I doubt there is any PSU that does 5.00V and 12.00V constantly, at various load level. The ATX specification is quite lax, and +-5% rarely cause ANY problem. Not to mention the efficiency is lower when you idle on a high-power PSU, than a low-power PSU.

Worse of all you only have 2x19" 1440x900, is there any game that a 8800GT can't handle, let alone SLI?

i see the marketing dept has been working overtime again

You would not need a 1kw PSU. The Corsair 620 HX demonstrated it could run SLi GTX, so no way is a 1Kw needed.

While I'd agree that replacing the Hiper would be an idea, most peoples opinons on Hiper on this forum have been vented often enough, a quality 700 watt or if you want to be xtra sure an 850 would be enough.

Personally I would look at the Enermax Infiniti 720 or 650 then sell your GTS and get the new 8900GTX that is due for release near xmas. Its possible it will use the 8 pin connector as well so the Infiniti will be a natural choice.
Enermax 720 watt review
Oh I would also start saving for a decent 24 inch monitor to get the best out of the card.

SLi GTS review and they used a Zeus 650 watt.

I would get a bigger monitor than 19" but 19" is big enough for me that and I could never go back to a single display.

The 8800gts I have at the moment is OK but does struggle on a few games when everything is fully maxed out i.e BF2142 slows to 25fps when the bombs go off take it to 8xaa and its in the 30 range.

And I will consider a new card BUT as Im water cooling you have to take into account that its the card and a block I have to buy which is a pita.

Great shame that about the monitor.

I am curious if your struggling with BF2142. I know that the net code is pretty crap so it can lead to lag. Which drivers do you have and what OS?

[Blitzen]

I use everest to monitor the sensors as well as uGuru to double check.

Which will both probably be nowhere near.
Software to monitor you PSU outputs is ALWAYS wrong. Even if it were right, 4.98 is well within the 5% tolerance allowable.
Test using a DMM to find the true results.

Who told you that 900W was your draw now? If it was a PSU calculator then chances are that is wrong aswell (i havent found one yet that is any good).

If the 730W unit you already have is any good then its more than enough for what you have.

But if you did upgrade, a 1000W would be a good idea. Nice and future proof.

No such thing tbh.

I use a 19" @ 1400x900 aswell with a 800gts and dont get the lag. Have you taken a look around all of your system to se if the problems lie elsewhere?

Agreed for all things apart from uGuru.
uGuru is a dedicated chip to measure these things, and is considered quite accurate.
I just compared uGuru's voltage readings with a multimeter on my DMM and there was a 0.03 difference between them on the +5v line. The +12v line was smack on. the USB +5v was 0.03 too (DDM was higher).
I might do some readings on the CPU voltage off the points on the board and compare that too next week (too busy at the moment).
Considering that was with a £5 DDM, which probably isnt calibrated brilliantly, that's pretty dam accurate from uGuru

[Blitzen]

Yep.....The software i meant was things like Everest/Speedfan. They are never ever right.

The only thing about uGuru, although its fine for the Voltage readings, is that its temperature die readings are bloody awful

[daza]

Everest reads the same voltages as uGuru and is always the same.

[Clunk]

Everest reads the same voltages as uGuru and is always the same.

That is interesting, maybe the dodgy voltage thing is an Asus problem with everest then?
