Hello, I need to run this query past everyone before I pull the trigger on an order.

Im going to be running the following.

Armoursuite P50R with 120mm fans (antec ones).
Prolimatech Cpu cooler with 2 antec 120mm white led fans in push pull.
i7 920 G0 at around 3.8ghz
OCZ Reaper 4GB (2x2GB) DDR3 PC3-14400C7 1800MHz Dual Channel
(was told dual channel is about same performance as trichannel, this is cheaper with better timings).
Gigabyte UD5 EX motherboard
1x GTX275
1xGTS250
2x SATA2 HDD's
1x SATA2 DVDRW

The gfx cards ARE NOT going to be run in SLI, they are used for folding, the 275 will be run 24/7 folding as my gaming needs are low ill use the 250 for BF2, and then folding when not in use.

All this off a Corsair 520w modular.

is this safe of do I need a higher spec Corsair Modular ? If so which one ?

Thankyou.
 
Hi,

One of the best and newest PSU's on the market is the Corsair HX 750. The reason for suggesting a 750 watt PSU is to reduce load on the PSU and therefore the life expectancy, because we all know that heavy load on a PSU creates heat and therefore reduces its efficiency and life expectancy.

Oh and its one of the best modular PSU's around at the moment.

From experience with a similar set-up (I have that power supply), I find that my power supply is heating up a great deal with only one graphics card an Nvidia GTX 275

To sum up if from the impression you are giving, you will have the set-up under load for long periods of time I would recommend that there is sufficient safety margin to protect your valuable equipment, after all it is recognised that power supplys become less effective over periods of time.
 
I don't know why you guys go for branded PSs? most are made by CWT and then re-badged.

" Channel Well Technology Co., Ltd. was founded in Tao Yuan, Taiwan. They have been manufacturing power supplies
since 1993. Since then, their products have shown up under different disguises including Antec, 2theMax, Thermaltake
Koolance, and Xigmatek, CWT themselves and now Corsair. CWT is one of the more complete OEM manufacturers
producing not only power supplies for the retail market, but also for the industrial sector.

I got a CWT OEM 550W 38amp on the 12v rail for £25.
I would really look into the PS you want then get the OEM version.
 
Hi,

While I agree that a lot of manu's do indeed use PSU's like the one mentioned above, in the case of Corsair, I understand they ask a company like Seasonic to build them to their own designs.

Seasonic build the modular ones, CWT make the non modular ones i think

But id say youd be better off with the 650 or 750w version. My 750w has 4 pci-e connectors which you'd need 3 of with a GTX 275 + 250
 
850 is overkill on pretty much any machine. Corsair's 620W Modular or 650W should be the max, for environmental and sanity reasons.

Also, it will last you longer? What are you talking about. If it's using more electricity then it's going to burn itself out faster, and technology is getting more energy efficient, not less.

GPU's are also progessing on and on which means to be on the safe side, a higher PSU should be considered. If a GTX 295 recommends a 680W PSU for your system, then i hate to see the recommended system power requirement for the GTX 300 series, the ATI 5800 series isn't really a problem, but i still predict a recommended system power requirement of 700W considering the 4800 series recommend's 600W.

I agree a 650W Corsair PSU is efficient currently, but if GPU's require more power as they have proved so far, then either a 750W or an 850W PSU should be considered and some people would rather be on the safe side.
