Best PSU possible - 4x 12V rails if poss

[Agent WD40]

Hi Guys,

I'm looking at a new PSU. I currently have an Enermax Noise Taker 600W and I feel that I need more stable power.

Budget isn't an issue on this one, can be either £80 - £200. I'm not fussed I just want the best for my PC.

I'm wanting 4x 12V rails with a good amount of amperage going through them but it has to be efficient. As in the range of about 85% efficacy at full load.

My system is in my sag so please let me know which is going to be best.

Many thanks,

Agent.

Have a look at some of these. Have never used thermaltake but +/-3% is better than most and surely 700w will have enough amps though the rails:

Theres also the ones with the ati logo next to them. That must show some good rails as crossfire ati cards cause problems on most psu's

The declared characteristics are truly impressive. The FX700-GLN has four +12V lines with a current of 15A each, and the only limitation to their combined load is the overall wattage of the unit, i.e. 680W for the main rails. In other words, the manufacturer promises you can load this power supply through one 12V power rail only.

TBH it's probably best if you go for something with decent single rail Ampage or a dual rail with switchable for single rail. quad rails are likely, as hilighted by Dutch, to be low ampage per rail so more likely to be overloaded.

Personally I'd go for a 580W Tagan Modular.

Hi Guys,

thanks for all of your replies.

I'm just after a PSU which will be very stable and not have too much "wobble" when at load and hence resulting in a more stable clock.

My system does drain a lot of power so I'm really after a strong, reliable and highly efficient PSU.

Any suggestions?

Yes and no, the PSU I linked to has two 15A 12V rails purely for a PCIe videocard and still has 15A for the CPU and 15A for the rest without a combined limit so you can load the PSU with 4x15A without a problem.

Do you not reckon that for your rig a good psu with 500+w would be ok. From what ive heard about crossfire cards causing probs on dual rail psu's id go for a tagan where its switchable between single and dual rails and if under dual it loads too high it switches automatically

PCP&C Turbo-Cool 1KW is the best PSU i know of, fraid your looking at a bit more than 200 for it though, still you did say money is no object.

• 1000W continuous and 1100W peak power
• NVIDIA® SLI™ READY component
• +12VDC Rails Total 66A (70A Peak)
• Extended ATX form factor fits most std cases
• High-efficiency design (85%) with .99 PFC
• Amazingly quiet!!
• Dual PCI Express video power connectors
• 15 drive connectors (6 SATA, 8 Molex, 1 mini)
• The industry's strongest warranty (5 years)

unlikely with your rig youl be anywhere near 1000w so wont have the full 85% efficiency though.

Uses 3 +12 V rails, two with 16A and one with 36 A which is 66A but has 70A peak rating.

I knew it sounded too perfect! I can't find any one in the UK who sells then!!

Oh well. Looks like the hunt continues..

there is a place in the uk but alas its a competitor and the psu is £350. If you are only using 1.4v on the cpu why do you need so much power??? I think those psu's are pretty damn noisey too.

Yes and no, the PSU I linked to has two 15A 12V rails purely for a PCIe videocard and still has 15A for the CPU and 15A for the rest without a combined limit so you can load the PSU with 4x15A without a problem.

Just takes one rail to overload though and your in trouble. I'd say it's just cutting it a bit fine. I think you'll also find you can't load all rails to 15A at once so could run out of ampage even so. In fact you can't as the supply is 680W and 4x15A on 12V is 720W.

Seasonic S12-600 is highly regarded

I recommend that one, especially for SLI/Crossfire duty, my OCZ 600W Powerstream couldn't cope with 2 7800GTXs.

UI'm wanting all that power for stability. I dont know why but of late i've become more and more worried about my CPU and how much its throwing out.

Yes I know I have a good PSU and yes it will probably last for years to come but I want to make sure that my system is going to last a while into the future with the PSU.

The idea of 4 12V rails does intreeg me a lot. I just souns sexeh tbh...

Is the FPS 700W any good? I think that has four rails.
