help what psu for core i7 system?

[Sniper101]

Hello Jonnyguru members,

I went here because i heard that Jonnyguru forum is an expert of PSU's.

I ordered my new pc components (and will watercool the cpu and gpu already have the watercooling components)
here is the list:

Lian Li Tyr PCX-500 case
650WATT or 750WATT PSU?
Intel Core i7 920 (do) overclocked to 3.0 or 3.2ghz
Intel Postville ssd 80gb (G2)
EVGA X58 SLI LE motherboard
EVGA GTX260 super clocked
Mushkin XP3-12800, 6GB, PC3-12800, 1600 MHz, cas 7-8-7-20.
Western Digital Caviar Black 500 GB, 7200 Rpm, 32 MB
Sony Optiarc dvd burner
Cherry G80-3000 keyboard black
Razer Salmossa mouse
And 6 to 7 fans

I'm really doubting wich PSU brand i should get (sillence is a priority, and i live in Europe, holland). First i wanted a Be quiet dark power pro 650W but the innards of seasonic used in Corsair are better then be quiet innards right? The innards of the be quiet dark power series (p7) are FSB.

Any way i tought i should get a Corsair HX620 or HX750. This is the PSU to get... But after reading Corsair forums and searching other forums i noticed complaints regarding the annoying "Coil whine" wich i indeed heard at some posts on youtube. And this issue is not an exeption more people having this issue. Offcourse there are solutions like disable C1E and EIST in bios it works sometimes or do something about Vsync. Anyway what would you recommend me for this setup? Please note il be using 6 or 7 casefans, and pump 5watt.
And i wont be using SLI not now not ever.

Also is a 750WATT a bit overkill for my setup? I tend to think the "headroom" is for more stability so the psu wont ever stress itself wattage or AMPS. Or is a 650 watt more then enough and also great for stability?

I'm realy tired of all the researching cant make a good choice doubting very much....Corsair or Be quiet? Help is much appreciated, thanks in advance.

Corsair HX620 would be more than enough power.
Antec TruePower New 650 is another good choice, or Antec Signature 650.

I think you mean to say "FSP" instead of "FSB"

In that case, the Corsair hands down. FSP is significantly lower in quality than the Corsair no matter what.

The headroom is also there so that you have enough power for future upgrades. In addition, power supplies last longer, are quieter, and cooler if you stay in the 40% to 60% range of their output.

With that, a good quality 650W is more then enough.

750W is a bit overkill, but if the HX620 is significantly cheaper, there's no reason to spend extra money on power you don't need.

Wouldn't say that about the Darkpower P7 Series 'cause it's a full custom design only used in that series.
Here some reviews (and Pics of the inside):

Too bad that they aren't testet by a really good, english site like Jonnyguru 'cause they are sold in Europe only (like the Arctic Fusion 550R)...

How moch Money do you want to spend?
For a little over 100€uros there is the Cougar-S, but only available at Atelco or Hardwareversand in Germany.
Or a 680W Tagan Superrock/Piperock II.

Looks similar to the Silverstone Eelement 700W and some of the Thermaltake Toughpoer XTs too me

Nah, those are based on FSP's LLC resonant design. This indy regulated platform used in the Dark Power P7 series is completely different.

No, it looks more than an Epsilon on steroids than that new Plattform.

Thanks for all the reply's guys appreciate it,

As for the PSU il go for the Corsair HX650 wich is now available here in holland. Its new, the HX620 is a couple of years old now. Since a lot of people recommend corsair it has better innards then FSP, il then go with the flow so to speak. Its sillent and rock solid thats all i want. And it does fit my money spending reserve. I could get a psu for arround 125 euro max is arround 180 dollar. The new one costs me arround 105 euro, so thats all good for me.

Thanks again for the help guys

There's no information available about the HX650 yet (other than the fact that it exists), but it's a safe bet that it's a better PSU than the FSP-built Be Quiet units.
