No, different external connectors can go on the same rail internally. One needs to see the connection diagram that usually comes with the documentation.

evolabs appear to not come with any of this

This is what I managed to find on Google:

Key Features:
Type: Evo Labs 700W Modular 80+ Certified
Modular PSU: Ez Connectors
Multi-GPU support: independent double +12V rails designed specially for dual graphic cards
AMD support: supports the newest Athlon 64 CPU by AMD
Intel support: supports the newest Core i3, i5 & i7 CPU by Intel
Active PFC: enhances utilization of energy
Ventilation: 1 x 14cm fan
Full range: AC full range input
Fan Speed Control
Energy Star
Short Circuit Protection
Over Voltage Protection
20+4 pin: compatible with all motherboards available on the market
Connections 20 +4 pin x 1 Peripheral Power Connectors x 4 Floppy Power Connector x 1 SATA Power Connector x 4 PCI-E (6+2pin) x 2 ATX 12V 8pin (4+4 pin) x 1

I would expect that PCI-E (6+2pin) x 2 go on one of the 12V+ rails and everything else is on the second one. That second rail is most probably overloaded at 4.8GHz.

Difficult to say, can you find the ratings of the +12V rails? If they are around 40A each, this should suffice.

the psu comes in on monday so will have a look then. if its higher ratings than mine will swap it over.

paradisiac · 25 Jul 2011 at 10:29

ok, well the 800w psu is here and both +12v rails say 32A and mine is 30A, so would this be a worthwile upgrade?

betaspin · 25 Jul 2011 at 13:06

32A against 30A per rail is 384W against 360W per rail. It is a relatively minor improvement but might be enough to tilt the balance, if the previous PSU was marginal. Worth giving it a go imho.

paradisiac · 25 Jul 2011 at 13:15

ok, will give it a bash and see how it gets on, if not then will just hang on at 4.6GHz until the next gen gfx cards come out and do psu at same time.

im guessing as they are the same psu, just different wattage, i can just swap the psu but keep the cables from the old one? save me have to cable tidy again.

betaspin · 25 Jul 2011 at 13:56

Oh, yes, the cables will be very much the same, most probably exactly the same, so far as electrical ratings are concerned.

paradisiac · 25 Jul 2011 at 14:00

ok awesome. is there any software that tells me what ampage/wattage is being pulled?

betaspin · 25 Jul 2011 at 20:51

It is possible to see what the CPU is pulling using several programs, my favourite is the sensor status of hwinfo32. Otherwise, you can see what is the consumption at the wall with a plug-in mains power monitor.

j.col · 25 Jul 2011 at 21:15

personally i use occt, to monitor the power usage.
download occt http://www.ocbase.com/perestroika_en/index.php?Download
run the cpu stress test, (its linpak, so similar to IBT) for about 30 mins.
in the results, you will see results for the cpu etc... but also for the +12v and +5v rail on the psu.
but i may be wrong on how accurate this is

paradisiac · 26 Jul 2011 at 18:12

well the 800w is in, is bigger than the 700w so was a squeeze

but its all in. need to do some cable tidying again but got a week on in a couple of weeks so will do it then. back up to 4.8GHz and 15 runs of IBT passed, so will do a bit of gaming later and see if the crashes start.

paradisiac · 26 Jul 2011 at 20:17

managed over 30mins of crysis 2, not had chance to try crysis, but i can only hope that the small psu increase has done the job.

betaspin · 26 Jul 2011 at 22:26

30 mins of Crysis 2 on max is certainly a good sign.

paradisiac · 30 Jul 2011 at 10:29

swapped out gfx cards to a single GTX460 and seems a lot more stable now

betaspin · 30 Jul 2011 at 11:03

Well, very good, but not that surprising given the reduced power consumption.

is it not around the same (think i read 300w somewhere) as it requires 2xPCI-e 6 pin, which is what the 2xHD6850 used (1 each)?

EDIT : re-read one of your posts and you mentioned the HD6850s were around 230w each, so is a big difference
