(silenty) replacement psu

[lanceuppercut]

running a core2/8800gts that is going to be upgraded to a i5 2500k/either 4xx or 5xx series nvidia card and has come to my attention that my psu (sparkle 460w psu) might not be beefy enough to run it at its overclocked settings (brought a prebuilt bundle from scan with it running at 4.5ghz)

will my psu be able to power my bits, if not, what silent recommendations are there that wont break the bank?

I opted for a Seasonic X760. sheer class.

Seasonic 560 should be able to run just about any single GPU setup. A good 500w can run a Gtx 580 even though its specifications state 600w. I pull just under 400w from the wall artificial load on both my 2600k + 580.

is that an overclocked 2600k? as i'm planning to run mine overclocked..

[tanassi]

I run a i7 2600k and a 6870. Both properly OC'ed. I opted for a higher wattage PSU because of the fan curve: the more power it draws, the more the fan will spin (usually). Thats why I opted for a Seasonic X760 (noise and squeel/ coile whine free): the load will never put the fan into overdrive (it's a hybrid fan with 3 settings, silent until a certain load, then 16db fan spin and then... I dont know, I never get that far).

how would this one cope with either a gtx560 or 560ti: 520W Seasonic S12II-520 Bronze, 80 PLUS Bronze, 85% Eff', EPS 12V, 120mm Silent S2FC Fan, ATX v2.3

I was wondering the same thing.

Your old components are much less power efficient than the new ones, and even though the new system will be faster, it probably doesn't use any more power; possibly less.

interesting, would i cause any damage to any components if i upgraded the board/cpu/gfx then if i doesn't work due to the psu not being beefy enough *then* upgrade the psu if needed?

I own this PSU myself but not gtx 560 Seasonic S12II-520 Bronze shouldn't have and issue with that video card but if you want some head room and not loading your PSU will make it more slient then get the Seasonic S12II-620 Bronze.

how about this Antec HCG-620, i can currently get it for £47 delivered compared to £60 for the seasonic.

both are 80 PLUS BRONZE certification (whatever that means!), the seasonic has a 120mm fan whilst the antec is higher rated and has a 135mm fan and the antec is, according to scan's page, more efficient by a whole 3%

taking all into account, antec should be better? bigger fan = slower spin to keep same temp? higher power rating and cheaper?

Antec HCG-620 is nothing more then slightly modified Seasonic S12II 620/M12II. The guts are the same but with 135mm ADDA fan instead of the ADDA 120mm. I cannot speak for how quiet it is but hey it's Seasonic.

if its essentially a seasonic (they're a good make, right?) i'm thinking that as i'm looking at a GTX560 Ti, the extra power overhead can't hurt.

Well yes, I don't recall Seasonic making any lemons but noise level varies from design to design. I've not heard much about the Antec HCG-620 being crazy loud as they not many reviews.

thats good enough for me, my current psu is quite old now so could do with a replacement

[systemlayers]

400w from the wall with a slightly overclocked 580 (833/2170) and overclocked 2600k (4.4ghz @ 1.28volt). I only have 1 hard drive and 2 solid state drives and slow moving fans mind you so overhead above the cpu and gpu is small.
I was benchmarking with my 580 and an old 8400 (which kept up with the 580 in 90% of my tests) from an old corsair 550vx.
So a seasonic 560 is more than enough trust me.
Also that 400w from the wall is under absolutely artificial loads you'll never ever see normally.
If you get a good 750w+ though you'll get more optimal efficiencies potentially (50% load) and even have space for SLI 580 if you ever wanted that.
