Safe PSU?

[cats_Paw]

Hi guys, my current rig has 2 years and after adding endlesly some "wow this would look cool" crap, i hitted dangerously close to my limit as i see it.

I got a 700W thermaltake thoughtpower powering :

a Q6600, its not oced now, but it will be to 3.200 (400x8) at 1.37Vcore probably.
Asus rampage formula as motherboard.
2 ddr2 ram sitcks rated at 800mhz 4-4-4-12, and i will leave them there.
3 hdds sata 3,5
2 4850 in crossfire with custom cooling (going to molex) currently non oced, will eb up to 735 as they can go that high, memory probably very little oc. (in near future im thinking of a GTX560 ti or a pair of oced 6850 in crossfire)
-I have a Frontal led panel with fan controler,
-4 cold catodes,
-a p500 thermaltake pump rated at 24W in a liquid cooling system with aproximate length of 3 meters total run,
-1 92mm fan
-5 120mm fans
-2 120 mm led fans
-1 250 mm fan
-sound blaster x-fi titanium
-tv card
-might be forgetting something 8(


Now i used extreme psu calculator v2.5.

and under 95% load and 10% capacitator agging recomends very close to 700 (680 i think).

My computer used to run very quiet (ofc long ago), and now PSU is noticebly louder, and it keeps turned on after the PC is off for a short time to cool it with the fan.

Im thinking of getting myself a PSu with more headroom, mainly something between 850 and 1100W good quality.

Im not a rich person so i need to take care of the money ill spend on it.

Since availability is an important factor as you might know, i found myself the options and would like your opinion on them:

Chieftec APS-1000C: 162 Euros
Corsair TX950W: 180 Euros
Corsair CMPSU-850TX: 160 Euros
Scythe Chouriki 2 1000W: 167 Euros
Thermaltake Toughpower XT 875W: 137 Euros
Antec TruePower Quattro 1000: 175 Euros

As you can see im working in the 120-200E budget, but any extra save is important. However, if a 40E diffrance means i get the antec quattro instead of thermaltake XT 875W (assuming ofc that its a huge diffrence), i wont think it twice.

For those who know quite a lot about PSUs but dont quite know those models, ill post the links to them:

Under the picture there is a small dropdown menu saying "especificaciones", you can press that to see the tecnical data submited by the webpage (not the manufacturer, but sometimes they just copy/paste).

So far im leaning towards the antec quattro, can you give me your opinions?

If you want to state that i should get a certain product from a certain brand, do so, just remmber that it might be a lot more expensive here, and maybe not even availedible.

Thanks for your input.

6850 uses less power then 4850 and a 560 uses bout 40% more then a 4850

and where did you get he figure 735 watts from you not even using 500 watts

but for a good budget psu this is your best option

http://www.alternate.es/html/product/Fuentes_de_alimentacion_A_partir_de_600_vatios/XFX/PRO750W/478655/?tn=HARDWARE&l1=Energ%C3%ADa&l2=Fuentes+de+alimentaci%C3%B3n&l3=Desde+750+vatios++++

each of my gpus eats up to 119W when oced, the cpu 143-145w, each hdd 30W, pump 24W, cathodes are 6W each pair, each 120MM fan 2.4W, and the 250MM eats up to 4.8W.
Frontal panel, soundblaster x-fi and tv card: no idea but im sure it eats some more.
add the dvds and u already hit 600W, in ofc a perfect scenario. (im working on the assumption that system willl be running 95% load, this might happen few times, but better safe than sorry.

Besides this is W only, im more worried about amps

 

[obsidian86]

so does you gpu,cpu,hdd's,pump,cathodes and fans run 100% all the time ?

 

[cats_Paw]

When im playing anything that has a high stress on cpu/gpu (like crysis for example) yes.
Everything is turned on after all. (i dont have a power saving option becouse if im not using the computer its off).
And i dont care about "all time", all it takes is 1 peak to *** everything up. Also 2 year+ is a time when a PSU might start having some problems, or at least i think so. I dont know if buying a 750W psu is even worth the cash if u have a 700W one. seems like buying a gtx 570 when you have a gtx560
To see my maximum power hunger i used extreme calcualtor v2.5 and i looked for the highest peak possible in my system.

 

[obsidian86]

actually it doesn since any good modern psu can provide 10-20% over its capacity if needed


and to get that gpu's an cpu to the max you need to run linx and furmark at the same time

crysis doesn even use 75% of your max power draw at all

b ut the xfx psu i linked earlier would even be too much for your pc

750 watts is ebough for even 6970 crossfire or gtx 570 sli,850 watts is for 2 gtx 480/580/5970/6990 range

 

[cats_Paw]

I agree its enought for that, im looking for "more than enought", considering all my parts, not just the gpus/cpu.
Acording to this forums general info on gpus for 2 580, 1k PSU is recommended...

I also heard that they "can" provide more, but thats not safe at all in my book.

Again, you are missing the point, i dont want to have a PSU that is enoguht for 75% load on my system. I want a psu that will leave room for upgrades, at 100% load.

I already destroyed 1 PC due to a bad PSU, and its not that expensive to get a 800-1k PSU nowdays anyway.

 

[obsidian86]

the xfx 850 is also a good option then

http://www.alternate.es/html/product/Fuentes_de_alimentacion_A_partir_de_600_vatios/XFX/PRO850W/478657/?tn=HARDWARE&l1=Energ%C3%ADa&l2=Fuentes+de+alimentaci%C3%B3n&l3=Desde+750+vatios++++


and i meant 75% of your total gpu/cpu power

 

[cats_Paw]

That last one looks like a nice option, just need to check how well it does on reviews.
http://www.guru3d.com/article/geforce-gtx-570-sli-review/13
"800 to 1kw if planning to do any overclocking", if im thinking of a 560 ti in sli in the future, im thinking of geting something quite powerfull. Note that a pc that they test does not carry any aditional low Watt taking parts like esta fans, catodes, dvds etc.

 

[obsidian86]

thats the gtx 570 review not a gtx 560 review

the xfx pro psu's are the same as the corsair TX V2

so the xfx pro 850 = corsair tx 850 v2

http://www.alternate.es/html/product/Fuentes_de_alimentacion_A_partir_de_600_vatios/Corsair/CMPSU-850TXV2/517601/?tn=HARDWARE&l1=Energ%C3%ADa&l2=Fuentes+de+alimentaci%C3%B3n&l3=Desde+750+vatios++++

 

[cats_Paw]

i know, but isint it quite close ? in fact OCed 560 eats more than a stock 570. I know you think im taking an overkill, but i went with a 700W PSU and im really unfontable with the signs it gives me : Bad 3d performance, sometimes random blue screens, and game freze.

If i get a 1kilowat PSu and use 800 ill be perfectly happy, but i want want to have a 850W PSU running at 851W, if possible id like to avoid my PSU running at more than 90% of its capacity (into this im also factoring noise and temperature).

From the options i posted in the original post, Thermaltake is the cheapest, but according to reviews its a very good product.
I remmber from an older review antec 1000 quattro was also a great product, and its 40E more expensive.

 

[obsidian86]

good psu's are rated at their continues capacity at a certain temp and your pc will never run 100% during any game i cam promise you that

the corsair tx 850 v2/xfx pro 850 are better then the thermaltake 875

and this is the best 1kw on that site

this is second best

[cats_Paw]

Its a bit more expensive, but i actually like that psu, i can eat less fried chicken and more rice for 2 weeks in order to get it.

Any idea where i can find a good review on that product?

I tried google but didnt find a decent one.

I will only check if it fits well in my case (kandalf LCS) and if it does im probably gonna take it.

 

[obsidian86]

haven found a review yet but based on silverstone history

its made by enhance electronics the same company that made the antec tpq range and most of silverstones 750 watt + range

i got reviews on the 750/850/1200 strider gold range and they seem to be excellent

size shouldn be a problem silverstone always made smallish power supplies

 

[cats_Paw]

Its a great PSU, ill be going with it. I found the Total specs about the build itself, and its very solid. Some minior problems inthe plastic quality material used inside but very minor.
I also wanted to ask you something:

What is the most important diffrence between those 2 PSUs?

I can see the diffrence itself in sepecs, im wondering how much of a diffrence it will be in real life situations (1kilowat PSU is overkill as you well pointed out, so .. )
